Vercel's guide explains that Google uses Core Web Vitals field data from real users—specifically Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS)—to influence search ranking, while Lighthouse lab scores are not considered. The post details how field data is collected via the Chrome User Experience Report (CrUX), which excludes iPhone users and requires pages to be sufficiently popular and publicly discoverable. It notes that page experience is one of many ranking factors, with query relevancy and content quality being substantially more important.

## Evidence

Verbatim from https://vercel.com/blog/how-core-web-vitals-affect-seo:

> Google only considers the Core Web Vitals field data when ranking your site. Google does not consider your Lighthouse score in any way for search ranking.
