Questions people ask us
What are Core Web Vitals?
Three measurements Google uses as a ranking signal: LCP (how fast the main content shows), INP (how fast the page reacts to taps) and CLS (how much the layout jumps). Good = LCP under 2.5 s, INP under 200 ms, CLS under 0.1.
Why is there no field data for my site?
Google needs enough real visitors (Chrome users) to publish field data. Small sites get lab data only — still useful, just not what ranking uses.
Mobile or desktop?
Mobile. It is where most Indian traffic is and what Google indexes first.
