Intro
Google has confirmed that it now renders all webpages, including those that are heavy on JavaScript, as part of its search indexing process. This update was discussed in a recent episode of Google’s “Search Off The Record” podcast, featuring Zoe Clifford from the rendering team alongside Martin Splitt and John Mueller from Search Relations.
Comprehensive Rendering for Search Indexing
During the podcast, Clifford detailed how Google processes web pages using a headless browser, ensuring that all content, including that which relies heavily on JavaScript, is fully indexed. This rendering process simulates how a user would experience the webpage, allowing Google to capture the complete content after all scripts have executed and the page has fully loaded.
Clifford stated, “We run a browser in the indexing pipeline so we can index the view of the web page as a user would see it after it has loaded and JavaScript has executed.” This approach applies to all HTML pages, ensuring a thorough indexing process, although it does not extend to other content types like PDFs.
Google's Commitment to Comprehensive Indexing
The podcast revealed that Google is committed to rendering every HTML page, despite the resource-intensive nature of this process. This dedication underscores Google's effort to ensure that even JavaScript-heavy websites are fully accessible and indexed, enhancing the visibility and accessibility of web content.
Introduction of Evergreen Googlebot
The discussion also touched on Google's adoption of the “Evergreen Googlebot” in 2019. This version of Googlebot stays up-to-date with the latest stable release of Chrome, improving its capability to render and index contemporary websites, which often employ advanced JavaScript frameworks.
Implications for Website Owners and Developers
-
Enhanced JavaScript Processing: Websites utilizing significant JavaScript can be assured that Google will index them effectively.
-
Importance of Website Speed: Despite improved JavaScript handling, website loading speed remains a crucial factor for user experience and SEO.
-
Simplicity and Accessibility: Simplifying website design where possible can aid both search engines and users, especially those with slower internet connections or older devices.
-
Testing and Optimization: Tools like Google’s Fetch As Google can help webmasters ensure their sites are properly rendered and indexed.
-
Broad Accessibility: Developers are encouraged to ensure that core content is accessible even if JavaScript fails to load, catering to users with diverse needs and capabilities.
Conclusion
Google's advancements in rendering technology offer greater flexibility for developers but emphasize the continued importance of optimizing website performance and usability. By focusing on creating fast, user-friendly websites, developers can ensure a positive experience for both Google and their audience.
