HTTP/3 does not have a direct impact on SEO in spite of its faster efficiency, Google states.
Google Browse Advocate John Mueller exposes a theory that the faster speed of HTTP/3 can straight affect
a site’s SEO. This subject is addressed during 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 question:
Could the use of HTTP/3 enhance SEO since it improves performance?
HTTP/3 uses performance advantages over HTTP/2 and HTTP/3. Nevertheless, the efficiency gains are not likely to make a difference regarding SEO.
Mueller On The SEO Impact Of HTTP/3
Mueller begins his response by mentioning Google does not use HTTP/3 as a ranking aspect or in web crawling:
“Google does not utilize HTTP/3 as a factor in ranking at the minute. As far as I know, we do not utilize it in crawling either.”
Google primarily uses HTTP/1 for web crawling. Googlebot supports HTTP/2 but only uses it when there’s a clear benefit over HTTP/1.
Assistance for HTTP/3 is likely a long way off. Websites that select to embrace it early will not see a direct enhancement in search rankings, Mueller describes:
“In regards to performance, I presume the gains users see from using 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 factor. While making a faster server is constantly an excellent idea, I question you ‘d see a direct connection with SEO just from using HTTP/3. Similar to how you ‘d be hard pushed to finding a direct connection to using a much faster kind of RAM in your servers.”
Mueller gave a similar reaction when asked about HTTP/3 in December 2021.
Nevertheless, he recommended HTTP/3 might “possibly indirectly” impact core web vitals.
I don’t believe we crawl with http/3 but that doesn’t mean you will not see favorable effects for users (and with that, possibly indirectly core web vitals too).

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