The new evergreen Googlebot

Googlebot is the crawler that visits web pages to include them within Google Search index. The number one question we got from the community at events and social media was if we could make Googlebot evergreen with the latest Chromium. Today, we are happy to announce that Googlebot now runs the latest Chromium rendering engine (74 at the time of this post) when rendering pages for Search. Moving forward, Googlebot will regularly update its rendering engine to ensure support for latest web platform features.

What that means for you

Compared to the previous version, Googlebot now supports 1000+ new features, like:

• ES6 and newer JavaScript features 
• IntersectionObserver for lazy-loading 
• Web Components v1 APIs

You should check if you’re transpiling or use polyfills specifically for Googlebot and if so, evaluate if this is still necessary. There are still some limitations, so check our troubleshooter for JavaScript-related issues and the video series on JavaScript SEO.
