HTTP/3 does not have a direct influence on SEO in spite of its faster efficiency, Google states.
Google Search Advocate John Mueller unmasks a theory that the faster speed of HTTP/3 can directly impact
a site’s SEO. This subject is addressed during the November 2022 edition of Google’s SEO office-hours Q&A session. Signed up with by the Google Browse Relations group, Muller answers the following question:
Could the use of HTTP/3 improve SEO due to the fact that it enhances efficiency?
HTTP/3 offers performance advantages over HTTP/2 and HTTP/3. Nevertheless, the efficiency gains are not likely to make a difference concerning SEO.
Mueller On The SEO Impact Of HTTP/3
Mueller starts his action by mentioning Google does not use HTTP/3 as a ranking factor or in web crawling:
“Google doesn’t use HTTP/3 as a factor in ranking at the moment. As far as I understand, we don’t use it in crawling either.”
Google mainly uses HTTP/1 for web crawling. Googlebot supports HTTP/2 but only uses it when there’s a clear benefit over HTTP/1.
Support for HTTP/3 is likely a long way off. Sites that choose to embrace it early will not see a direct enhancement in search rankings, Mueller discusses:
“In regards to performance, I suspect the gains users see from utilizing HTTP/3 would not suffice to significantly impact the core web vitals, which are the metrics that we utilize in the page experience ranking factor. While making a quicker server is constantly a good idea, I question you ‘d see a direct connection with SEO only from utilizing HTTP/3. Similar to how you ‘d be tough pressed to finding a direct connection to utilizing a faster sort of RAM in your servers.”
Mueller gave a similar action when inquired about HTTP/3 in December 2021.
Nevertheless, he suggested HTTP/3 could “potentially indirectly” impact core web vitals.
I don’t believe we crawl with http/3 but that doesn’t indicate you will not see favorable effects for users (and with that, possibly indirectly core web vitals too).
