Multi-Site Speed Comparison
Core Web Vitals side-by-side for up to 3 websites — real Google PageSpeed data, mobile and desktop.
How it works
Each domain runs through the official Google PageSpeed Insights API (mobile strategy). The table compares the performance score plus the four Core Web Vitals: FCP, LCP, TBT and CLS — the same metrics Google Search Console uses for ranking signals. Results are cached 6 hours per domain.
