TTFB
Time to First Byte
The time between a browser's HTTP request and receiving the first byte of the response, measuring server responsiveness.
รายละเอียดทางเทคนิค
Search engines evaluate ttfb as part of their ranking algorithm, which considers hundreds of signals including content relevance, page experience (Core Web Vitals), backlink authority, and technical implementation. Google's crawlers (Googlebot) render JavaScript-heavy pages using a headless Chromium engine, but server-side rendered content is still discovered and indexed faster. Implementing ttfb correctly provides both direct ranking benefits and indirect improvements through better user experience.
