Posted by HTTP/3 does not have a direct impact on SEO despite its faster performance, Google says.
Google Search Supporter John Mueller unmasks a theory that the faster speed of HTTP/3 can directly affect
a site’s SEO. This subject is resolved throughout the November 2022 edition of Google’s SEO office-hours Q&A session. Joined by the Google Browse Relations group, Muller addresses the following question:
Could making use of HTTP/3 enhance SEO because it improves efficiency?
HTTP/3 provides efficiency advantages over HTTP/2 and HTTP/3. However, the efficiency gains are not likely to make a distinction concerning SEO.
Mueller On The SEO Effect Of HTTP/3
Mueller starts his action by mentioning Google doesn’t utilize HTTP/3 as a ranking element or in web crawling:
“Google does not use HTTP/3 as a factor in ranking at the minute. As far as I understand, we don’t use it in crawling either.”
Google mainly utilizes HTTP/1 for web crawling. Googlebot supports HTTP/2 but just uses it when there’s a clear advantage over HTTP/1.
Support for HTTP/3 is likely a long way off. Websites that select to adopt it early will not see a direct improvement in search rankings, Mueller discusses:
“In regards to performance, I suspect the gains users see from using HTTP/3 would not suffice to substantially impact the core web vitals, which are the metrics that we use in the page experience ranking aspect. While making a much faster server is always a great concept, I question you ‘d see a direct connection with SEO just from utilizing HTTP/3. Comparable to how you ‘d be difficult pushed to discovering a direct connection to using a quicker sort of RAM in your servers.”
Mueller gave a similar response when inquired about HTTP/3 in December 2021.
Nevertheless, he suggested HTTP/3 could “possibly indirectly” affect core web vitals.
I do not think we crawl with http/3 but that does not mean you won’t see positive impacts for users (and with that, potentially indirectly core web vitals too).

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