Search engines (especially Google) evaluate performance as one of the ranking factors, because fast sites provide a better user experience. ### What performance includes: 1. **Page loading speed** How quickly a user sees the first content and can start interacting. The longer the wait, the higher the chance they leave. 2. **Core Web Vitals (Google's key metrics)** Three main indicators: - **LCP (Largest Contentful Paint)**: loading speed of the main block; - **FID / INP**: responsiveness and delay on first interaction; - **CLS (Cumulative Layout Shift)**: layout stability (nothing should jump during loading). 3. **Resource optimization** How the site's files load: images, fonts, CSS, JS. Their size and count directly affect speed. 4. **Server response time** If the server is slow, the page will be slow too, even with an optimized frontend. ### Why this matters for SEO: - search engines rank fast sites higher; - users leave less often and interact with the page longer; - improving performance directly reduces the bounce rate. Summary: **performance is the technical speed and convenience of loading a site, which affects both ranking and user behavior.**For the reviewerNote to the moderator (optional)Visible only to the moderator.
