One of Python’s strong points is its interactive capabilities. By running python you start the interactive interpreter, or REPL, which allows you to perform quick calculations or explore and experiment with your code. In Python 3.13, the interactive interpreter has been completely redesigned with new modern features.

Python’s REPL has remained largely unchanged for decades. Instead, alternative interpreters like IPython, bpython, and ptpython have addressed some of the built-in REPL’s shortcomings, providing more convenient interactive workflows for developers. As you’re about to learn, Python 3.13 brings many significant improvements to the interactive interpreter.

In this tutorial, you’ll:

• Run Python 3.13 and explore the new REPL
• Browse through the help system
• Work with multiline statements
• Paste code into your REPL session
• Navigate through your interpreter history

The upgraded REPL is just one of the new features coming in Python 3.13. You can read about all the changes in the what’s new section of Python’s changelog. Additionally, you can dig deeper into the work done on free threading and a Just-In-Time compiler.

Get Your Code: Click here to download the free sample code that shows you how to use some of the new features in Python 3.13.

A New Interactive Interpreter (REPL) in Python 3.13

To try out the new REPL for yourself, you need to get your hands on a version of Python 3.13. Before the official release in October 2024, you can install a pre-release version. After October 2024, you should be able to install Python 3.13 through any of the regular channels.

A REPL, or a Read-Eval-Print Loop, is a program that allows you to work with code interactively. The REPL reads your input, evaluates it, and prints the result before looping back and doing the same thing again.

Note: To learn about the built-in REPL in Python and how it works in general, check out The Python Standard REPL: Try Out Code and Ideas Quickly.

In any version of Python, you can start this interactive shell by typing the name of your Python executable in your terminal. Typically, this will be python, but depending on your operating system and your setup, you may have to use something like py or python3 instead.

Once you start the REPL in Python 3.13, you’ll see a small but noticeable difference. The familiar Python interactive shell prompt, consisting of three right angle brackets (>>>), is now colored differently from the rest of the text:

The color difference indicates that the shell now supports color. In the new shell, color is mainly used to highlight output in tracebacks. If your terminal doesn’t display color, then the new REPL will automatically detect this and fall back to its plain, colorless display.

If you prefer to keep your interpreter free of color even when it’s supported, you can disable this new feature. One option is to set the new environment variable PYTHON_COLORS to 0:

Shell $ PYTHON_COLORS=0 python Python 3.13.0rc2 (main, Sep 13 2024, 17:09:27) [GCC 9.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> Copied!

Setting PYTHON_COLORS=0 disables color in the REPL. If you set the environment variable to 1, you’ll get the colored prompt and output. However, since it’s the default, this is rarely necessary.

Before going any further, you’ll exit the REPL. As you may know, the old REPL, that you’ve used on Python 3.12 and earlier, has been widely commented on for the following idiosyncrasy:

Python >>> exit Use exit() or Ctrl-D (i.e. EOF) to exit Copied!

The shell clearly understands your intention to end the session. Still, it makes you jump through hoops and add parentheses to your command. In Python 3.13, the REPL now understands special commands that you can write without any parentheses:

• exit or quit: Exit the interpreter
• help or F1: Access the help system
• clear: Clear the screen

Having these commands more easily available is a small thing, but it removes some friction when using the interactive interpreter. You can still use parentheses and type something like exit() if you prefer. These commands are not reserved though. That means that you could shadow them with variable assignments:

Python >>> exit = True >>> exit True >>> exit() Traceback (most recent call last): ... TypeError: 'bool' object is not callable >>> del exit >>> exit Copied!

Here you create a variable named exit, effectively disabling the exit command. To end your REPL session, you can either delete the exit variable or use one of the alternative ways to exit the interpreter.

Note: Even with the new improvements, the built-in REPL is not as powerful as some of the third-party alternatives. If you’re already using any of these, there’s no immediate reason to revert back to the standard interactive interpreter.

The main advantage of the new REPL is that it’s installed together with Python. In other words, it’ll always be available for you. This is great if you find yourself in a situation where you can’t or don’t want to install a third-party library.

You can learn more about the alternative interactive interpreters in the following tutorials:

• Unlock IPython’s Magical Toolbox for Your Coding Journey
• Discover bpython: A Python REPL With IDE-Like Features
• Boost Your Coding Productivity With Ptpython

You can also read more about alternative REPLs in the guide to the standard REPL.

Hey everyone!

The 2024 Linux Display Next hackfest concluded in May, and its outcomes continue to shape the Linux Display stack. Igalia hosted this year’s event in A Coruña, Spain, bringing together leading experts in the field. Samuel Iglesias and I organized this year’s edition and this blog post summarizes the experience and its fruits.

One of the highlights of this year’s hackfest was the wide range of backgrounds represented by our 40 participants (both on-site and remotely). Developers and experts from various companies and open-source projects came together to advance the Linux Display ecosystem. You can find the list of participants here.

The event covered a broad spectrum of topics affecting the development of Linux projects, user experiences, and the future of display technologies on Linux. From cutting-edge topics to long-term discussions, you can check the event agenda here.

Organization Highlights

The hackfest was marked by in-depth discussions and knowledge sharing among Linux contributors, making everyone inspired, informed, and connected to the community. Building on feedback from the previous year, we refined the unconference format to enhance participant preparation and engagement.

Structured Agenda and Timeboxes: Each session had a defined scope, time limit (1h20 or 2h10), and began with an introductory talk on the topic.

• Participant-Led Discussions: We pre-selected in-person participants to lead discussions, allowing them to prepare introductions, resources, and scope.
• Transparent Scheduling: The schedule was shared in advance as GitHub issues, encouraging participants to review and prepare for sessions of interest.

Engaging Sessions: The hackfest featured a variety of topics, including presentations and discussions on how participants were addressing specific subjects within their companies.

• No Breakout Rooms, No Overlaps: All participants chose to attend all sessions, eliminating the need for separate breakout rooms. We also adapted run-time schedule to keep everybody involved in the same topics.
• Real-time Updates: We provided notifications and updates through dedicated emails and the event matrix room.

Strengthening Community Connections: The hackfest offered ample opportunities for networking among attendees.

• Social Events: Igalia sponsored coffee breaks, lunches, and a dinner at a local restaurant.

• Museum Visit: Participants enjoyed a sponsored visit to the Museum of Estrela Galicia Beer (MEGA).

Fruitful Discussions and Follow-up

The structured agenda and breaks allowed us to cover multiple topics during the hackfest. These discussions have led to new display feature development and improvements, as evidenced by patches, merge requests, and implementations in project repositories and mailing lists.

With the KMS color management API taking shape, we discussed refinements and best approaches to cover the variety of color pipeline from different hardware-vendors. We are also investigating techniques for a performant SDR<->HDR content reproduction and reducing latency and power consumption when using the color blocks of the hardware.

Color Management/HDR

Color Management and HDR continued to be the hottest topic of the hackfest. We had three sessions dedicated to discuss Color and HDR across Linux Display stack layers.

Color/HDR (Kernel-Level)

Harry Wentland (AMD) led this session.

Here, kernel Developers shared the Color Management pipeline of AMD, Intel and NVidia. We counted with diagrams and explanations from HW-vendors developers that discussed differences, constraints and paths to fit them into the KMS generic color management properties such as advertising modeset needs, IN\_FORMAT, segmented LUTs, interpolation types, etc. Developers from Qualcomm and ARM also added information regarding their hardware.

Upstream work related to this session:

• KMS color management properties (new version - v5);
• IGT Tests;
• drm_info draft support of v4 DRM/KMS plane color properties;
• gamescope draft support of v4 DRM/KMS plane color properties;
• Kwin WIP implementation of DRM/KMS plane color properties.

Color/HDR (Compositor-Level)

Sebastian Wick (RedHat) led this session.

It started with Sebastian’s presentation covering Wayland color protocols and compositor implementation. Also, an explanation of APIs provided by Wayland and how they can be used to achieve better color management for applications and discussions around ICC profiles and color representation metadata. There was also an intensive Q&A about LittleCMS with Marti Maria.

Upstream work related to this session:

• Wayland color management protocol;
• Wayland color representation protocol;
• HDR support merged on Mutter;
• Color management protocol on Mutter;
• Color management protocol on GTK.

Color/HDR (Use Cases and Testing)

Christopher Cameron (Google) and Melissa Wen (Igalia) led this session.

In contrast to the other sessions, here we focused less on implementation and more on brainstorming and reflections of real-world SDR and HDR transformations (use and validation) and gainmaps. Christopher gave a nice presentation explaining HDR gainmap images and how we should think of HDR. This presentation and Q&A were important to put participants at the same page of how to transition between SDR and HDR and somehow “emulating” HDR.

We also discussed on the usage of a kernel background color property.

Finally, we discussed a bit about Chamelium and the future of VKMS (future work and maintainership).

Power Savings vs Color/Latency

Mario Limonciello (AMD) led this session.

Mario gave an introductory presentation about AMD ABM (adaptive backlight management) that is similar to Intel DPST. After some discussions, we agreed on exposing a kernel property for power saving policy. This work was already merged on kernel and the userspace support is under development.

Upstream work related to this session:

• Kernel series: Add support for ‘power saving policy’ property (merged)
• Mutter: issue: support for “power saving policy” property
• Kwin: MR Draft: backends/drm: add support for the “power saving policy” property

Strategy for video and gaming use-cases

Leo Li (AMD) led this session.

Miguel Casas (Google) started this session with a presentation of Overlays in Chrome/OS Video, explaining the main goal of power saving by switching off GPU for accelerated compositing and the challenges of different colorspace/HDR for video on Linux.

Then Leo Li presented different strategies for video and gaming and we discussed the userspace need of more detailed feedback mechanisms to understand failures when offloading. Also, creating a debugFS interface came up as a tool for debugging and analysis.

Real-time scheduling and async KMS API

Xaver Hugl (KDE/BlueSystems) led this session.

Compositor developers have exposed some issues with doing real-time scheduling and async page flips. One is that the Kernel limits the lifetime of realtime threads and if a modeset takes too long, the thread will be killed and thus the compositor as well. Also, simple page flips take longer than expected and drivers should optimize them.

Another issue is the lack of feedback to compositors about hardware programming time and commit deadlines (the lastest possible time to commit). This is difficult to predict from drivers, since it varies greatly with the type of properties. For example, color management updates take much longer.

In this regard, we discusssed implementing a hw_done callback to timestamp when the hardware programming of the last atomic commit is complete. Also an API to pre-program color pipeline in a kind of A/B scheme. It may not be supported by all drivers, but might be useful in different ways.

VRR/Frame Limit, Display Mux, Display Control, and more… and beer

We also had sessions to discuss a new KMS API to mitigate headaches on VRR and Frame Limit as different brightness level at different refresh rates, abrupt changes of refresh rates, low frame rate compensation (LFC) and precise timing in VRR more.

On Display Control we discussed features missing in the current KMS interface for HDR mode, atomic backlight settings, source-based tone mapping, etc. We also discussed the need of a place where compositor developers can post TODOs to be developed by KMS people.

The Content-adaptive Scaling and Sharpening session focused on sharpening and scaling filters. In the Display Mux session, we discussed proposals to expose the capability of dynamic mux switching display signal between discrete and integrated GPUs.

In the last session of the 2024 Display Next Hackfest, participants representing different compositors summarized current and future work and built a Linux Display “wish list”, which includes: improvements to VTTY and HDR switching, better dmabuf API for multi-GPU support, definition of tone mapping, blending and scaling sematics, and wayland protocols for advertising to clients which colorspaces are supported.

We closed this session with a status update on feature development by compositors, including but not limited to: plane offloading (from libcamera to output) / HDR video offloading (dma-heaps) / plane-based scrolling for web pages, color management / HDR / ICC profiles support, addressing issues such as flickering when color primaries don’t match, etc.

After three days of intensive discussions, all in-person participants went to a guided tour at the Museum of Extrela Galicia beer (MEGA), pouring and tasting the most famous local beer.

Feedback and Future Directions

Participants provided valuable feedback on the hackfest, including suggestions for future improvements.

• Schedule and Break-time Setup: Having a pre-defined agenda and schedule provided a better balance between long discussions and mental refreshments, preventing the fatigue caused by endless discussions.
• Action Points: Some participants recommended explicitly asking for action points at the end of each session and assigning people to follow-up tasks.
• Remote Participation: Remote attendees appreciated the inclusive setup and opportunities to actively participate in discussions.
• Technical Challenges: There were bandwidth and video streaming issues during some sessions due to the large number of participants.

Thank you for joining the 2024 Display Next Hackfest

We can’t help but thank the 40 participants, who engaged in-person or virtually on relevant discussions, for a collaborative evolution of the Linux display stack and for building an insightful agenda.

A big thank you to the leaders and presenters of the nine sessions: Christopher Cameron (Google), Harry Wentland (AMD), Leo Li (AMD), Mario Limoncello (AMD), Sebastian Wick (RedHat) and Xaver Hugl (KDE/BlueSystems) for the effort in preparing the sessions, explaining the topic and guiding discussions.

My Kickstarter for my latest Python book is still going on for another eight days. Now is a great time to pre-order the book as well as get my other Python books.

The project is fully funded, and I added a stretch goal.

Stretch Goal

The stretch goal is $5000 or 350 backers. If we reach either of those, I will create a video course version of the book and release it to all backers. I think being able to show JupyterLab in a video format may be an even better medium for teaching this type of topic, although the book may be better for quick browsing.

What You’ll Learn

In this book, you will learn how about the following:

• Installation and setup of JupyterLab
• The JupyterLab user interface
• Creating a Notebook
• Markdown in Notebooks
• Menus in JupyterLab
• Launching Other Applications (console, terminal, text files, etc)
• Distributing and Exporting Notebooks
• Debugging in JupyterLab
• Testing your notebooks

Rewards to Choose From

As a backer of this Kickstarter, you have some choices to make. You can receive one or more of the following, depending on which level you choose when backing the project:

• An early copy of JupyterLab 101 + all updates including the final version (ALL BACKERS)
• A signed paperback copy (If you choose the appropriate perk)
• Get all by Python courses hosted on Teach Me Python or another site  (If you choose the appropriate perk)
• T-shirt with the book cover  (If you choose the appropriate perk)

Get the book on Kickstarter today!

The post JupyterLab 101 Kickstarter Stretch Goal appeared first on Mouse Vs Python.

As track leads for search in Drupal CMS (formerly Starshot), we developed a concept and aligned it with the other leaders. To refine our approach, we conducted a survey to gather feedback and identify potential improvements. This article presents the survey results and the planned implementation.

As KDE grows, so does the interest in each of its projects. Gathering all KDE news in one place no longer works. The volume of updates coming from the KDE community as a whole has become too large to cover in its entirety on the Dot. With this in mind, we are archiving the Dot, but keeping its content accessible for historical reasons.

The news coming out of the community was curated and edited for the Dot. The current rate of news items being published today would've not only made that impractical, but would have also led to things being unjustly left out, giving only a partial view of what was going on.

But we are not leaving you without your source of KDE news! We have figured out something better: we have worked with KDE webmasters to set up a blogging system for contributors. You can now access Announcements, Akademy, the Association news, and the news from your favorite projects directly, unfiltered, unedited, straight from the source.

Or... If you want to keep up with what is going on in ALL KDE projects and news on a daily (often hourly) basis, use the Planet! Access it on the web or add an RSS feed to your reader. You can also follow KDE news as it happens in our Discuss forums and talk about it live with the rest of the community. You can even follow @planet.kde.org@rss-parrot.net on Mastodon to stay up to date.

Do you have kids? Maybe nieces and nephews? Or maybe you work in a school environment? Maybe it's just friend's who know you're a programmer and ask about how they should go about introducing programming concepts with them.

In a previous article I wrote about the importance of the HTTP headers and web security avoiding the technical stuff. In this article I want to get into all the dirty technical details. 

Some time ago we came across the HTTP Header Analyzer by Dries Buytaert. This tool, as the name suggests, analyses the headers of the HTTP response from a website. There are other header analysers out there, but this one, published by the creator of Drupal, also takes into account Drupal-specific headers. The tool displays a report of all headers found, along with an explanation of the purpose of the header and notes on the values of the header, sometimes including recommendations for better values. It also displays information about missing headers that should be present. 

With all this information, the tool gives a score based on the missing headers, warnings and notices detected during the analysis. On the first runs on our website, I have to admit that the score was not bad, but not good: 6/10. Now I am happy to say that we get a score of 10/10 on the home page. Unfortunately, not all pages can get the highest score, as I explain below.

…

DrupalCon Barcelona 2024 kicked off with contribution workshops, the Women in Drupal award ceremony, and Dries Buytaert’s 40th State of Drupal address. Key announcements included the upcoming Drupal CMS 1.0 launch, AI integration, and the Experience Builder initiative.

Do you ever feel like you’re living ahead of your time when you watch those world-conquering AI movies? The only reason such movies are gaining popularity with every passing day is because a similar reality is not too far away. The world today is living wire-free and digitally. Online is the popular and future-demanding way of living. And for your business to prosper in this online world, mastering SEO is a necessity! Now, to achieve optimal visibility, you need to understand the three most important concepts: crawlability, indexability, and mobile-first indexing. Why all of them? These three concepts are codependent, and they make the most crucial pillars to determining how search engines discover, understand, and rank your website. Your goal here is to make your website stand out in this ever-competitive online space; your tool: SEO. In this blog, we focus on the what and why of all three concepts and the best practices to help your website rank higher on Google search results. Introduction to Crawlability, Indexability, and Mobile-First Indexing Each of these three concepts is connected to the other and therefore, can get confusing for the masses to understand the difference without proper analysis. Crawlability refers to the process search engines like Google use to discover web pages easily. In simple words, Google discovers web pages by crawling, using computer programs called web crawlers or bots. Indexing is the process that follows crawling. Indexability refers to the process where search engines can add pages to their index. Google indexes by analyzing pages and their content to add them to the database of zillions of pages. Mobile-first indexing refers to Google’s crawling process as it prioritizes the mobile version of website content over its website version to inform higher rankings. Why These Concepts Matter in Today’s SEO Landscape With the continuous evolution of Google and other search engines, your SEO strategies need to be top-notch. With Google prioritizing mobile traffic, and hence, its mobile-first initiative, optimizing your website for both crawlability and indexability is the need of the hour. Without proper measures implemented in these areas, your website may be heading towards stunted organic growth. And you don’t wish for that to happen, do you? So, go on reading till the end. What is Crawlability in SEO? Performed by crawler bots, crawlability is the ability of search engines to find and index web content. Google crawl bots are essential computer programs that analyze websites and collect their respective information. This information helps Google index websites and show relevant search results. Google crawl bots follow a list of web page URLs based on previous crawls and sitemaps. As crawl bots visit a page, they detect links on each page and add those links to the list of pages to crawl. These new sites then become a part of SERP results and change to existing sites. Furthermore, dead links are spotted and taken in to update the Google index. However,  it’s important to know how to get Google to crawl your site. If your website is not crawlable, chances are, some of your web pages won’t be indexed, leading to a negative impact on your website’s visibility and organic traffic, thus, affecting your site’s SEO numbers. Key Factors Affecting Crawlability While crawlability is crucial for optimizing your site’s visibility, there are several factors impacting it. Learn about some of the most crucial ones are below: Site structure – Your site structure plays a pivotal role in its crawlability. If any of your pages aren’t linked to any source, it won’t be easily accessible to crawl bots for crawling. Internal links – Web crawlers follow links while crawling your site. These crawl bots only find pages linked to other content. To get Google to crawl your site, make sure to have internal linking structures across your website, allowing crawl bots to easily spot these pages in your site structure. Robots.txt and Meta Tags – These two parameters are crucial to maximizing your crawl budget. Make sure to avoid commands that prevent crawlers from crawling your pages. Check your meta tags and robots.txt file to avoid common errors:       ◦ <meta name="robots" content="noindex"/>: This robots meta tag directive can block your page from indexing.       ◦ <meta name="robots" content="nofollow">: Although nofollow links allow your pages to be crawled, it exudes all permissions for crawlers to follow links on your page.       ◦ User-agent: * Disallow: /: This particular code bars all your pages from getting indexed. Crawl Budget – Google offers limited recommendations for crawl budget optimizations since Google crawl bots finish the job without reaching their limit. But B2B and e-commerce sites with several hundreds of landing pages can be at the risk of running out of their crawl budget, missing the chance of your web pages making their way to Google’s index for crawlability. Tools to Check and Improve Crawlability There are various tools in the digital realm that claim to improve crawlability. Let me highlight a few most popular tools you can use to improve crawlability: Google Search Console What better tool to analyze Google crawlability than its in-house tool? Although it’s not a surprise to know how often does Google crawl a site, i.e., once every 3 days to 4 weeks, there are no fixed times.  How to fix crawl errors in Google Search Console? You can analyze your page traffic, keyword data, page traffic broken down by device, and page rankings in SERP results. Google Search Console also provides you with insights on how to rank higher on Google search results following Google algorithms. Submit sitemaps and provide comprehensive crawl, index, and related information directly from the Google index. Screaming Frog SEO Spider This is the tool you want to use to take charge of two essential jobs at once: crawl your website and assist with SEO audits. This web crawler helps increase the chances of your web content appearing in search engine results. Analyze page titles, and meta descriptions, and discover duplicate pages – all the actions that impact your site’s SEO. The free version can crawl up to 500 pages on a website and can find if any pages are redirected or if your site has the dreaded 404 errors. If you need more detailed features, the paid version brings many to the table, including JavaScript rendering, Google Analytics integration, custom source code search, and more. XML Sitemaps A roadmap for search engine crawlers, XML sitemaps ensure crawlers reach the important pages that need to be crawled and indexed. For better crawlability, ensure that the following requirements are met while creating sitemaps: Choose Canonical URLs: Identify and include only your preferred URLs (canonical URLs) in the sitemap to avoid duplicates from the same content accessible via multiple URLs. CMS-generated Sitemaps: Most modern CMS platforms can automatically generate sitemaps. For platforms like Drupal, you get to apply the benefits of the Drupal XML sitemap module that allows you to create XML sitemaps adhering to sitemaps.org guidelines. Check your CMS documentation for specific instructions on sitemap creation. Manual Sitemaps for Small Sites: For websites with fewer than a few dozen URLs, create a sitemap manually using a text editor and follow standard sitemap syntax. Automatic Sitemap Generation for Large Sites: For larger websites, use tools or your website’s database to automatically generate sitemaps. Make sure to split your sitemap into smaller files if necessary.Submit Sitemap to Google: Submit the sitemap using Google Search Console or the Search Console API. You can also include the sitemap URL in your robots.txt file for easy discovery. Bear in mind that submitting a sitemap doesn’t ensure Google will crawl every URL. It serves as a hint to Google but does not guarantee URL crawling or indexing. What is Google Indexing in SEO? The process of adding pages of a website to a search engine’s database to display them in search results when relevant is called indexing. Search engines like Google, crawl websites and follow links on the sites to add new pages. They analyze their content to determine its quality and relevance. When search engines find quality and relevant content, they add those pages to their index. One of the main processes of the Google search engine is indexing. Google Indexing allows it to discover and analyze web content and display them as search results to users, resulting in higher SEO ranks. Factors That Influence Indexability Given the importance of indexability for search engines to work properly, it is only understood that several factors can hinder or contribute to its influence. Below is a list of the common factors that influence the indexability of website pages: Content Quality and Relevance - Search engine bots or bot crawlers are fonder of high-quality content. Well-written, original, informative, and content with clear headings and organized structure that is relevant to users make it to the list of indexed pages in search engines. Canonical Tags and Duplicate Content - Search engines cannot index duplicate content. Duplicate content raises confusion during Google page indexing. Therefore, canonical tags are the counter activity here to solve duplicate content issues. These tags help search engines distinguish between original and duplicate content while indexing the relevant content pages. Technical Issues – Technical issues like broken links, page load times, noindex tags or directives, redirect loops, etc., can contribute to a negative impact on SEO, preventing crawling or indexing your site content. Using Google Search Console for Indexing Your Site Various tools allow you to check whether or not your web pages are crawlable or indexed. However, Google being a giant search engine, it’s highly recommended to use Google indexing service to meet your SEO goals relatively easily. Let me walk you through a brief guide as to how you can use Google Search Console request indexing for your website. Verify Website Ownership: Confirm ownership by adding an HTML file or meta tag. Submit Your Sitemap: Submit your sitemap URL in the Sitemaps section to help Google discover your significant pages faster. Use the URL Inspection Tool: Submit specific pages for re-crawling or direct indexing requests. Monitor Coverage Issues: Use the "Coverage" report to identify and fix indexing issues like blocked pages. Improve Internal Linking: Ensure proper internal links for better crawling. Enhance Content Quality: Avoid low-quality or duplicate content to improve indexing chances. Fixing Common Google Indexing Issues Here are some common Google indexing issues (similar and in addition to those of crawlability issues) you may come across on your website that affect its visibility and performance in SERP results: Low-Quality Content Google always targets original and relevant content to rank highest in user search results. If your web content is low quality, scraped, or includes keyword stuffing, chances are, that Google won’t index your web pages. Make sure to cater to the needs of your users and provide relevant information to them that is unique and aligned with the Webmaster Guidelines. Not Mobile-Friendly Google prioritizes mobile-friendliness while crawling web pages. If your website content isn’t mobile-friendly, Google is likely to not index it. Make sure to implement an adaptable design, improve load times, compress images, get rid of pop-ups, and keep finder reach in mind while curating your website. Missing Sitemap Without proper sitemaps, you cannot get Google to crawl your site. Make sure to use XML sitemaps instead of HTML. It helps enhance your website performance in search engines. Once you’ve created the sitemap, submit it with the help of Google Search Console or robots.txt file. Poor Site Structure Websites with poor navigability are often missed by crawl bots. Poor site structure negatively impacts your site crawlability and indexability. Make sure to use a clear website structure and good internal linking for SEO purposes. Redirect Loops Redirect loops block Google crawl bots from indexing your pages correctly, as these bots indulge in these loops and cannot crawl your website. Check your .htaccess or HTML sources of your website for unintentional or incorrect redirect loops. 301 redirects for permanent pages and 302 redirects for temporary pages should be used to prevent this issue from occurring. What is the difference between crawlability and indexability Since these two concepts are connected, oftentimes people mistake one for the other.Crawling is the process of search engines accessing and reading web pages. On the contrary, indexing is the process of adding pages to Google index. Indexing comes after crawling. However, in selective cases, indexing website on Google or other search engine bots can take place without reading the content. What is Mobile-First Indexing As the name suggests, mobile-first indexing means Google crawl bots prioritize indexing the mobile version of website content over desktop. This Google mobile-first indexing is meant to inform rankings. If your website content is not optimized for mobile devices, it could hamper your SEO ranks, even for desktop users. Having mobile-friendly content gives your website the edge for getting recognized for relevance and accessibility, thus improving visibility in search results. Mobile-first indexing is highly prioritized today to meet the expectations of the growing number of mobile users. For a seamless mobile browsing experience, it is crucial to have relevant, navigable content to reduce bounce rates and improve the overall SEO performance of your website. The Impact of Mobile-First Indexing on SEO Mobile-first indexing is a necessity today. It highly impacts the implications of crawlability and indexability, necessary for SEO purposes. Optimize your website for mobile devices using an adaptable design. You can develop your website specially for mobile devices using a responsive web design with a mobile-friendly theme or a completely separate mobile website. Alternatively, you can develop app-based solutions or AMP pages to enhance your website performance on mobile devices. Small businesses, e-commerce and B2B websites, and enterprise-level organizations stand highly affected by this shift to mobile-first indexing. It’s high time for these organizations to develop mobile-friendly websites to meet their customers’ expectations. Additionally, SEO professionals have witnessed a surge in demand for mobile-responsive website design and development services. Therefore, aligning your SEO strategies to Google’s algorithm to stand alongside your competitors in this mobile-first landscape is key. Are mobile-first indexing and mobile usability the same? Definitely not. A website may or may not be usable on mobile devices, despite containing content that calls for mobile-first indexing. Best Practices for Optimizing Crawlability and Indexability in a Mobile-First World In a mobile-first world, it is important to optimize your web pages in the direction of gaining greater visibility and better performance in search engine results. Below are a few best practices supported by Google and other search engines that can help improve the crawlability and indexability of your website for Google mobile-first indexing as a priority in the present scenario. Mobile-friendliness: Effective responsive designs serving the same HTML code on the same URL, irrespective of the device used, is key to optimizing mobile-friendliness. Your site should adapt to the screen size automatically. According to Google, adaptable web designs work best for ease and maintenance. Navigation: Mobile users often use one hand to operate their devices and therefore, make sure to design your website with liquid navigation. Implement larger buttons, and menus, add ample spaces, and additional interactive elements for easy finger-friendly navigation. A pro tip: maintain a minimum tap target size of 48 x 48 px. Content Consistency: Use the same meta robot tags for the desktop and mobile versions of your website. Ensure that your robot.txt file has not barred access to the main content, specifically on mobile devices. Google crawl bots can crawl and index content only when mobile-first indexing is enabled on your website. Page Speed Optimization: Avoid lazy loading of web content. Slow loading times hamper user experience for mobile users. Make sure to optimize your web images without compromising quality. Minimize HTTP requests and leverage browser caching. Ensure faster loading times for your web content across the globe with the help of CDN distribution. Tools and Techniques for Ongoing Optimization With mobile-first indexing in mind, it only makes sense to stay updated with the ongoing trends to check your site for mobile-friendliness. Here are a couple of ways to do the necessary: Use Mobile-Friendly Test Tools with Google Search Console Open your account in Google Search Console and click on “Mobile-Friendly Test” in the Enhancements sections. Input the URL to be analyzed for mobile-friendliness and proceed with the “Test URL” button. Review the report generated that presents you with the result of whether or not the page is mobile-friendly and also offers suggestions to address any issues found. If not mobile-friendly, the list of issues may include small text, appearance issues, content too wide for the size of the screen, or other similar and/or related usability problems. Once you’ve addressed these issues, re-test the page using the Mobile-Friendly Test tool. Run regular audits like this on Google Search Console to ensure the mobile-friendliness of pages across your site. Optimize Core Web Vitals Pay attention to page speed, interactivity, and visual stability to align with Google’s Core Web Vitals. One of the ways to go about it is by utilizing the PageSpeed Insights tool by Google. It allows you to examine web pages and provides data based on both mobile and desktop content versions, along with improvement suggestions. You can simply input the URL in the tool and click on “Analyze.” Proceed from here accordingly to generate a report that checks your website’s mobile-friendliness with a Core Web Vitals Assessment. Higher metrics mean greater mobile responsiveness! Common Pitfalls to Avoid in Mobile-First Indexing Ignoring the Mobile Version of Your Site: Make sure all content, inclusive of text and media, is accessible not only on the desktop version of your site but also on mobile devices. Maintain content parity and SEO rankings. Overlooking Technical SEO on Mobile: Mobile content also needs indexing for SEO purposes. Ensure that both your mobile and desktop sites use the same structured data for consistency. Doing so helps search engines properly analyze your web content. Slow Mobile Page Speed: Compress images, leverage browser caching, and minimize code to enhance the page loading speed for your mobile site. This way, you deliver a seamless user experience for mobile users. Final thoughts Crawlability and indexability are two significant entities that shape the SEO performance of your website. With Google prioritizing mobile-first indexing today, it’s time to roll up your sleeves and strategize a brand-new mobile-focused SEO strategy that aligns with Google’s algorithm and highlights your brand identity. With AI and machine learning increasingly shaping SEO today, optimizing for mobile devices isn’t just about adapting to algorithms—it’s about meeting user expectations and staying competitive. A mobile-friendly site with fast loading times, responsive design, and consistent content will improve search rankings and user experience. As mobile usage grows, embracing mobile-first strategies ensures businesses stay ahead, enhancing both visibility and customer satisfaction in the evolving digital landscape.
