Google Updates Testing Tools With Better JavaScript Support

Google Updates Testing Tools With Better JavaScript Support

Google has updated most of its testing tools with Googlebot evergreen rendering, which improves how the tools process modern websites.

With Googlebot now being “evergreen,” it will be continuously updated when a new version of Chrome is released.

“At its core the update is a switch from Chrome 41 as the rendering engine to the latest stable Chromium. Googlebot is now using the latest stable Chromium to run JavaScript and render pages. We will continue to update Googlebot along with the stable Chromium, hence we call it “evergreen.””

  • Search Console’s URL inspection tool
  • Mobile-friendly test
  • Rich results test
  • AMP test

Google notes that these updates went through extensive testing before being rolled out to everyone.

Lastly, users should be aware that Googlebot still uses the same user agent as it did before becoming evergreen.

That may change in the future, but at least for now there is no change to the user agent used in testing tools.
