A Excellent overall on the measured subjects

Loading speed is diagnostic only; it does not affect this grade or search ranking.

SubjectWeightScore
Interruption 35.71% not scored
Readability 28.57% not measured
Accessibility and keyboard 21.43% 88
Stability and weight 14.29% 100

This letter rests on 36% of the grade. The subjects marked “not measured” are left out rather than scored as zero (which would fail a site for something nobody looked at) or as full marks (which would be a claim we have not earned). How this is worked out.

Observed interruptions

Ad and tracker counts above are network requests, not counts of visible ads or separate companies. They do not affect the interruption score.

Interruption evidence is incomplete or needs review, so this subject is not scored. Missing evidence is not treated as an interruption-free page.

The type, and who can use it

Measured on 1 rendered page; latest measurement 2026-09-05. Every number is a mechanical fact about the page, not a judgment of its design.

WhatMeasuredThe bar
Body type size not measured 16px, the browser default
Characters per line not measured 45–90
Line height not measured 1.5 (WCAG 1.4.8)
Text contrast not measured 4.5:1 (WCAG AA), 7:1 (AAA)
Text column not measured at least 45%
Reflows at phone width yes WCAG 1.4.10
Dark mode no noted, not scored
Automated accessibility checks 1 automated check failed (1 serious): color-contrast WCAG 2.1 A and AA, via axe-core
Keyboard no trap; focus visible on 100% of stops never trapped, always visible
Structure main landmark, 0 h1, no skipped heading levels a main landmark, one h1, no skips
Alt text no content images every content image
Reader mode parses parses (Firefox’s Readability)

Automated accessibility checks catch an estimated 30–40% of real problems, so “no automated violations detected” is a floor, not a certificate. We never say “accessible”. How these are scored.

Recorded automated findings

Cookie dialog blocks the page, with no refuse button 0.35 Needs review; not scored

These records are retained for inspection. Only verified interruption evidence contributes to that subject; uncertain records are not silently treated as clean. Metering keeps its separate grade cap. These costs are not currently applied as search-ranking multipliers.

Measurement dates

Oldest evidence 50 days old. At least one subject is due for rechecking (30 days or older). Dates refer to the evidence, never the card rebuild.

Measurement history

Newest 4 saved observations. Each describes a sampled page at that time; older, failed or held observations do not override the current reviewed card. Raw automated findings may have been superseded by later review or detector replay. No previous grade is inferred.

Think this is wrong? It may well be — the measurements cover only a handful of pages. Any reviewed admission decision and its dated evidence are shown above. Re-measurement on request is not built yet, so there is no button here that would do anything. When it exists it will be free and it will be on this page.
