Content creators and publishers use many channels beyond their own websites to reach their audiences. As people gravitate toward firsthand perspectives and different content formats, we want to make it easier for site owners and creators—even those without their own website—to get a consolidated view of how all of their content is getting discovered on Search.

What : Removed a section on accessibility from the JavaScript SEO basics documentation . Why : The information was out of date and not as helpful as it used to be. Google Search has been rendering JavaScript for multiple years now, so using JavaScript to load content is not "making it harder for Google Search". Most assistive technologies are able to work with JavaScript now as well.

Why : Based on feedback, we're clarifying that Google uses both schema.org markup and the og:image meta tag as sources when determining image thumbnails in Google Search and Discover.

What : While moving over the information about the default file size limits of Google's crawlers and fetchers to the crawler documentation , we also updated the Googlebot documentation about its own file size limits. Why : The original location of the default file size limits was not the most logical place as it applies to all of Google's crawlers and fetchers, and the move enabled us to be more precise about Googlebot's limits.
What : Added preferred sources documentation for website owners. Why : To help publishers understand how to help their audience find their site as a preferred source.

What : We added a section on canonicalization best practices for JavaScript to our JavaScript documentation and the best practices for consolidation of duplicate URLs . Why : Canonicalization happens before and after rendering, so it's important to make the canonical URL as clear as possible. With JavaScript, this means setting the canonical URL to the same URL as in the original HTML or if that isn't possible, to leave the canonical URL out of the original HTML.
What : Clarified in our JavaScript documentation how Google's crawler handles noindex tags in pages that use JavaScript. Why : While Google may be able to render a page that uses JavaScript, the behavior of this is not well defined and might change. If there's a possibility that you do want the page indexed, don't use a noindex tag in the original page code.

Why : To clarify that site owners that make content improvements can see a rise in position in Google Search results without having to wait for the next major core update.
What : Consolidated robots.txt error handling documentation into a single spot. Why : We previously had information about robots.txt error handling in several places (specifically, HTTP status codes and Search Console documentation ), which lead to some confusion.

What : Added new documentation about crawling faceted navigation URLs . Why : While the information was already public in form of a blog post , it was never officially made into documentation.
What : Added a section about how Google's crawlers handle cache control headers in the overview of Google's crawlers . Why : While the information was already public in form of a blog post, it was never officially made into documentation.
