help PageSpeed Compare FAQ
What does PageSpeed Insights measure?
Google PageSpeed Insights evaluates a web page using Lighthouse and reports performance signals such as Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. It provides separate lab results and, when available, real-user Chrome data.
Is PageSpeed Insights the same as Lighthouse?
They use the same Lighthouse auditing technology for many performance checks, but PageSpeed Insights is Google's web interface and also includes Chrome User Experience Report data when a URL has enough traffic. Lighthouse can be run locally in Chrome DevTools or from the command line.
Does a high PageSpeed score guarantee fast rankings?
No. A score is a diagnostic signal, not a direct guarantee of search position. Google also evaluates relevance, content quality, links, technical accessibility, and real-world page experience.
What should I fix first after a PageSpeed test?
Start with issues that affect the main content, such as oversized images, render-blocking resources, and slow server response. PageSpeed Insights links each finding to a category such as opportunities or diagnostics, which helps separate likely improvements from lower-impact warnings.
