Requires Opti-Behavior Pro. Errors & Performance is a Pro module. View pricing or start the 6-month free trial.
The performance score condenses a page’s Core Web Vitals into a single 0–100 number so you can rank pages at a glance.
Requirements #
- Plan: Opti-Behavior Pro
Where to find it #
Go to Opti-Behavior → Errors Tracking → Performance. Each page shows its score alongside its vitals; the header shows Avg Performance across the site.

How the score works #
- The score is derived from the page’s real-user Core Web Vitals (such as LCP, INP, and CLS).
- Better vitals produce a higher score; a slow or unstable page scores lower.
- A higher number is better: treat scores as a quick triage, then open the vitals to see the specific weakness.
Expected result #
You can sort pages by score, fix the lowest first, and watch the score improve as vitals improve.
FAQ #
Why does my score differ from a lab tool? #
This score uses field data from your real visitors, so it reflects real conditions rather than a single lab run.
