Davide Previti, a SEO specialist, did a little research on the correlation between Lighthouse Performance Score and page visibility changes in the middle of the Google July 2021 Core Update.

The results were as follows: the "slowest" pages with a score below 25 decreased their visibility by 14%. Other groups did not show significant dynamics.

The research sample consisted of 100,000 URLs from 7,000 domains. Visibility was checked for 36,000 requests. He parsed the Lighthouse Performance Score with the Screaming Frog program, through the Page Speed ​​Insights API.
