A fast page holds attention; a slow one loses traffic before the content even shows. ## Why this matters to search engines 1. **The user factor** If a site loads in 3-5 seconds or longer, the bounce rate rises. The search engine sees that a person didn't wait, which means the page is not the best result for the query. That's a signal to lower it in the results. 2. **Search result satisfaction indicator** Fast loading means a higher chance that the user will read, click, and move on. And what matters to search engines is not traffic, but **quality traffic** that leaves satisfied. 3. **Core Web Vitals as an official ranking factor** Google directly includes loading speed and stability (LCP, INP, CLS) in the algorithm. Poor metrics mean a ranking penalty, especially on mobile. 4. **The competitive environment** All else being equal, a search engine will always favor the faster-loading site for the top spot, because it guarantees fewer "lost" users. Conclusion: **speed is an SEO signal channeled through audience behavior.** A slow site doesn't just irritate people, it gives the search engine grounds to consider it a worse answer, so it loses ranking and traffic.For the reviewerNote to the moderator (optional)Visible only to the moderator.
