You Can Pass 421 HTTP Status to Googlebot to Opt-out of Crawling over HTTP/2

Google has updated its documentation on Googlebot add some info on their ability to crawl through HTTP/2 and how to opt-out of it temporary if your site is having issues when being crawled over HTTP/2.

To opt-out from crawling over HTTP/2, instruct the server that’s hosting your site to respond with a 421 HTTP status code when Googlebot attempts to crawl your site over HTTP/2. If that’s not feasible, you can send a message to the Googlebot team (however this solution is temporary).


tl;dr marketing is a huge timesaver, Saijo does an excellent job and has really saved me missing a few big things that would have otherwise slipped by. It's one of the only two marketing newsletters I subscribe to and a great resource for our podcast.
