Google factors in Web Vitals (LCP, FID, CLS), and if the metrics are poor, the site ranks lower, all else being equal. 2. **Behavioral metrics** A slow site increases the bounce rate and reduces time on page. Search engines read this as a signal that the site does not provide a good user experience: rankings drop. 3. **Mobile priority** Google indexes sites using a mobile-first model. If the mobile version loads slowly, the SEO result suffers even for a fast desktop version. 4. **Worse indexing** Slow loading increases the load time for the search crawler, so it indexes fewer pages per crawl. As a result, some content may get indexed with delays or not indexed at all. --- **Summary:** good performance helps a site rank higher, get indexed faster, and retain traffic, meaning it improves SEO both technically and behaviorally.For the reviewerNote to the moderator (optional)Visible only to the moderator.
