However starting from September 2020, all sites were switched to mobile-first indexing, meaning Google is crawling the web using a smartphone Googlebot.

[3] There is increasing evidence Googlebot can execute JavaScript and parse content generated by Ajax calls as well.

A problem that webmasters with low-bandwidth Web hosting plans[citation needed] have often noted with the Googlebot is that it takes up an enormous amount of bandwidth.

Google provides "Search Console" that allow website owners to throttle the crawl rate.

[10] Since May 2019, Googlebot uses the latest Chromium rendering engine, which supports ECMAScript 6 features.

This will make the bot a bit more "evergreen" and ensure that it is not relying on an outdated rendering engine compared to browser capabilities.
