HTTP/3 doesn’t have a direct influence on SEO despite its faster performance, Google states.
Google Search Supporter John Mueller debunks a theory that the faster speed of HTTP/3 can directly affect
a site’s SEO. This topic is dealt with throughout the November 2022 edition of Google’s SEO office-hours Q&A session. Joined by the Google Search Relations group, Muller responds to the following concern:
Could using HTTP/3 improve SEO since it improves performance?
HTTP/3 uses efficiency benefits over HTTP/2 and HTTP/3. However, the efficiency gains are unlikely to make a difference regarding SEO.
Mueller On The SEO Effect Of HTTP/3
Mueller begins his reaction by mentioning Google doesn’t use HTTP/3 as a ranking factor or in web crawling:
“Google doesn’t use HTTP/3 as a factor in ranking at the minute. As far as I understand, we do not use it in crawling either.”
Google mainly utilizes HTTP/1 for web crawling. Googlebot supports HTTP/2 but only utilizes it when there’s a clear advantage over HTTP/1.
Support for HTTP/3 is likely a long way off. Sites that choose to adopt it early will not see a direct enhancement in search rankings, Mueller explains:
“In terms of performance, I presume the gains users see from utilizing HTTP/3 would not suffice to considerably affect the core web vitals, which are the metrics that we utilize in the page experience ranking element. While making a much faster server is always an excellent idea, I doubt you ‘d see a direct connection with SEO just from using HTTP/3. Comparable to how you ‘d be hard pressed to discovering a direct connection to utilizing a quicker kind of RAM in your servers.”
Mueller gave a comparable action when inquired about HTTP/3 in December 2021.
Nevertheless, he recommended HTTP/3 could “possibly indirectly” impact core web vitals.
I don’t think we crawl with http/3 however that does not mean you will not see positive results for users (and with that, possibly indirectly core web vitals too).

Mueller sounds more confident now in stating that there’s no effect.
