Sample: completed crawl jobs from May 3, 2026 to Oct 4, 2026. Statistics were generated at Oct 9, 2026, 01:25 PM.
Reported means, medians, interquartile ranges, and sample sizes are computed from available measurements only. Missing readability or Lighthouse results remain visible through the coverage values above.
Accessibility
Lighthouse accessibility is an automated screening result, not a complete WCAG conformance assessment. Scores are reported on the Lighthouse 0-100 scale.

- 84-95

Languages
Language rows use the detected language stored with the readability result. Formula scores are shown only within the language row where that formula is available.

Readability Indices
Formula outputs are separate scales. The table reports each available index with its own direction and sample size instead of averaging unlike formulas together.
