Sıkça Sorulan Sorular
What are Core Web Vitals?
Core Web Vitals are Google's three key metrics for measuring user experience: LCP (loading speed), INP (interaction speed), and CLS (visual stability). They have been used as a Google ranking signal since 2021.
Do Core Web Vitals affect SEO?
Yes. As part of Google's Page Experience signal, the Core Web Vitals score can lead to ranking differences among similar quality content.
Why is INP used instead of FID?
FID (First Input Delay) only measured the first interaction. INP measures the delay of all interactions on the page, providing a more comprehensive indicator of user experience.
What is CrUX data?
CrUX (Chrome User Experience Report) is field-based data collected from real Chrome users. Unlike lab data, it reflects real user experience.
