What is PageSpeed Score?
Definition
PageSpeed Score is Google's comprehensive performance metric, rating your site from 0-100 based on multiple factors including loading speed, interactivity, and visual stability.
Why It Matters
Higher PageSpeed scores correlate strongly with better SEO rankings, lower bounce rates, and higher conversion rates. Google has confirmed page experience is a ranking factor, and scores below 50 are flagged as 'poor' in Search Console.
How We Measure It
We run each store through Google's PageSpeed Insights API, which combines lab data from Lighthouse with real-world Chrome User Experience data. The score weights metrics like LCP, FID, CLS, and Time to Interactive.
