Low Lighthouse performance score: what it is, why it matters, and how to fix it

Google Lighthouse's overall performance score for this page (measured on mobile) is below the good threshold. 90+ is good, 50-89 needs improvement, and under 50 is poor. The score is a weighted roll-up of load and responsiveness metrics including LCP, CLS, and TBT.

The performance score is the single headline number Google's own tooling reports for a page. A low score signals a slow experience that hurts Core Web Vitals rankings and conversion rates — faster pages consistently convert better and rank higher.

Open the full PageSpeed Insights report for this page and work through its Opportunities and Diagnostics: compress and right-size images, eliminate render-blocking resources, reduce and defer JavaScript, and improve server response time. Fix the individual Core Web Vitals flagged in this audit first, as they carry the most weight.

This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it. It belongs to the performance family of checks.

Run a free Dr Urls audit: it crawls your site, detects low lighthouse performance score on every affected page, shows example URLs, and generates a ready-to-use fix task. Re-scan after fixing to verify the issue is gone.
