In 2021, Google is hosting a half-hour "ask me anything" session on vital signs on the web.During the AMA, someone asked if page experience was a binary ranking factor.

Philip Walton, Google's engineer in charge of web performance, replied that web vitals are mostly not binary ranking factors.

Google search advocate John Mueller confirmed during the AMA that while online vitals can affect rankings, relevance also plays a role.If site A is faster than site B, but B is more relevant to search user queries, site B will still outpace A.

Mueller also noted that sites that go from "needs improvement" to "good" are likely to see improved rankings.However, a site that is already good and has improved a millisecond or two in speed may not see a ranking change.

In 2021, Google updated the original blog announcement of Core Web Vitals.They confirmed that the page experience rollout will be complete by August 2021.
