The AJAX crawling scheme was introduced as a way of making JavaScript-based webpages accessible to Googlebot, and we've previously announced our plans to turn it down. Over time, Google engineers have significantly improved rendering of JavaScript for Googlebot. Given these advances, in the second quarter of 2018, we'll be switching to rendering these pages on Google's side, rather than on requiring that sites do this themselves. In short, we'll no longer be using the AJAX crawling scheme.

As a reminder, the AJAX crawling scheme accepts pages with either a "#!" in the URL or a "fragment meta tag" on them, and then crawls them with an "?_escaped_fragment_=" in the URL. That escaped version needs to be a fully-rendered and/or equivalent version of the page, created by the website itself.

With this change, Googlebot will render the #! URL directly, making it unnecessary for the website owner to provide a rendered version of the page. We'll continue to support these URLs in our search results.

We expect that most AJAX-crawling websites won't see significant changes with this update. Webmasters can double-check their pages as detailed below, and we'll be sending notifications to any sites with potential issues.

If your site is currently using either #! URLs or the fragment meta tag, we recommend:

We hope that this change makes it a bit easier for your website, and reduces the need to render pages on your end. Should you have any questions or comments, feel free to drop by our webmaster help forums, or to join our JavaScript sites working group.
