HTTP/3 does not have a direct effect on SEO despite its faster efficiency, Google states.
Google Search Supporter John Mueller unmasks a theory that the faster speed of HTTP/3 can straight affect
a website’s SEO. This subject is dealt with during the November 2022 edition of Google’s SEO office-hours Q&A session. Joined by the Google Browse Relations group, Muller answers the following question:
Could making use of HTTP/3 improve SEO because it improves performance?
HTTP/3 offers performance advantages over HTTP/2 and HTTP/3. However, the performance gains are unlikely to make a difference relating to SEO.
Mueller On The SEO Impact Of HTTP/3
Mueller starts his reaction by mentioning Google doesn’t utilize HTTP/3 as a ranking element or in web crawling:
“Google doesn’t use HTTP/3 as a factor in ranking at the minute. As far as I know, we don’t use it in crawling either.”
Google mainly uses HTTP/1 for web crawling. Googlebot supports HTTP/2 but just utilizes it when there’s a clear benefit over HTTP/1.
Support for HTTP/3 is likely a long way off. Websites that pick to embrace it early will not see a direct enhancement in search rankings, Mueller explains:
“In terms of efficiency, I believe the gains users see from utilizing HTTP/3 would not be enough to significantly affect the core web vitals, which are the metrics that we use in the page experience ranking element. While making a faster server is always an excellent idea, I question you ‘d see a direct connection with SEO just from using HTTP/3. Comparable to how you ‘d be tough pressed to discovering a direct connection to utilizing a much faster kind of RAM in your servers.”
Mueller gave a similar action when inquired about HTTP/3 in December 2021.
However, he suggested HTTP/3 could “potentially indirectly” impact core web vitals.
I don’t believe we crawl with http/3 however that doesn’t imply you will not see favorable results for users (and with that, potentially indirectly core web vitals too).

Mueller sounds more positive now in saying that there’s no impact.
