Performance

Core Web Vitals and page speed in the same audit

SiteGaps does not stop at a Lighthouse score. Speed issues sit beside SEO and security so you can explain why a slow LCP matters for both rankings and the sales conversation.

Metrics we surface

Reports highlight Largest Contentful Paint, Interaction to Next Paint (or TBT when that is what PSI returns), Cumulative Layout Shift, and related opportunities from the Lighthouse audit.

  • LCP — largest contentful paint
  • INP / TBT — interactivity
  • CLS — layout stability
  • FCP and overall performance category scores

Why agencies care

A prospect who fails Core Web Vitals already has a concrete, Google-named problem. Pairing that with missing meta tags or weak security headers gives you a tighter outreach hook than “we do SEO.”

Frequently asked questions

Where do the performance scores come from?

Core Web Vitals and Lighthouse categories are pulled from Google PageSpeed Insights for the URL you submit, then shown next to crawl-based SEO and security findings.

Lab data or field data?

PageSpeed Insights can include both lab (Lighthouse) and field (CrUX) data when Google has enough samples. The report surfaces what PSI returns for that URL.
