Frequently Asked Questions
Why are Core Web Vitals important for SEO?
Core Web Vitals measure user experience speed, visual stability, and interaction responsiveness. Google uses these metrics (especially LCP, FID/INP, and CLS) as a ranking signal, making speed directly linked to organic performance.
What is Largest Contentful Paint (LCP)?
LCP measures the time it takes for the main content of a page to render. A good LCP is 2.5 seconds or faster. Higher times prompt Google search warnings.
Why are security headers like CSP and HSTS crawled?
Search engines prioritize secure, trusted web destinations. Having correct Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS) headers protects visitors from scripting injections and reinforces search trust signals.
