Technical SEO FAQ · Core Web Vitals, Performance & HTTP
How should server performance be considered in Technical SEO?
Server performance affects:
- crawl capacity;
- user experience;
- TTFB;
- availability;
- rendering;
- migration reliability.
Google's crawling infrastructure explicitly considers server responsiveness when determining how aggressively it can crawl.
A server returning frequent 5xx errors can cause Google to reduce crawling.
