Site Quality
Site Quality (/site-quality) reports lab-measured performance and UX signals from Playwright-based audits of your pages.
What it is
Section titled “What it is”Per-URL lab results including Core Web Vitals (LCP, CLS), mobile readability, Lighthouse performance, and axe accessibility violations — summarized in a scorecard with page-level detail tables.
When to use it
Section titled “When to use it”- After onboarding or site quality re-run
- Before and after performance or mobile layout fixes
- When Unified Report flags Web Vitals or accessibility fails
How it works
Section titled “How it works”The site quality pipeline loads pages in a headless browser, records metrics, and ingests lab rows. Checks compare against Google-aligned thresholds (e.g. LCP ≤ 2.5s, CLS ≤ 0.1).
Step-by-step
Section titled “Step-by-step”- Open Site Quality in the sidebar (
/site-quality). - Review scorecard sections: HTTP, Web Vitals, Mobile, Lighthouse, Accessibility, Run.
- Inspect the page results table for URLs with fails or errors.
- Refresh data after scans complete; Re-run all scans for a full new lab pass.
Understanding results
Section titled “Understanding results”| Section | What it measures |
|---|---|
| Web Vitals | LCP, CLS |
| Mobile | Viewport, horizontal scroll, text size, tap targets |
| Lighthouse | Performance score (0–100) |
| Accessibility | Critical axe violations |
| Run | Navigation timeout / load failures |
Reference: Site quality scorecard checks.
- Lab scores vary by URL and run conditions — focus on consistent fails across runs.
- Navigation timeouts often indicate slow TTFB or blocking scripts on specific pages.
