HTTP/3 doesn’t have a direct effect on SEO regardless of its faster performance, Google says.
Google Search Supporter John Mueller unmasks a theory that the faster speed of HTTP/3 can straight impact
a website’s SEO. This subject is dealt with during the November 2022 edition of Google’s SEO office-hours Q&A session. Signed up with by the Google Search Relations group, Muller answers the following concern:
Could the use of HTTP/3 improve SEO because it improves efficiency?
HTTP/3 offers performance advantages over HTTP/2 and HTTP/3. However, the efficiency gains are not likely to make a difference regarding SEO.
Mueller On The SEO Impact Of HTTP/3
Mueller starts his response by mentioning Google doesn’t use HTTP/3 as a ranking aspect or in web crawling:
“Google does not use HTTP/3 as a factor in ranking at the minute. As far as I know, we do not use it in crawling either.”
Google mostly uses HTTP/1 for web crawling. Googlebot supports HTTP/2 however just uses it when there’s a clear benefit over HTTP/1.
Support for HTTP/3 is likely a long method off. Sites that select to embrace it early won’t see a direct enhancement in search rankings, Mueller discusses:
“In terms of efficiency, I think the gains users see from utilizing HTTP/3 would not suffice to substantially 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 a good concept, I question you ‘d see a direct connection with SEO only from utilizing HTTP/3. Similar to how you ‘d be hard pushed to discovering a direct connection to utilizing a faster kind of RAM in your servers.”
Mueller offered a similar reaction when asked about HTTP/3 in December 2021.
Nevertheless, he suggested HTTP/3 could “potentially indirectly” impact core web vitals.
I don’t think we crawl with http/3 however that doesn’t imply you won’t see positive results for users (and with that, potentially indirectly core web vitals too).
