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.

Assessed 2 sampled pages. The largest detected ad area was 0% of a sampled viewport. No qualifying obstructive prompts were detected.

This is a sample, not a promise that the whole site has no interruptions. Ad detection can miss formats and content outside the sampled view. Older scans did not check visibility or overlapping ad rectangles as thoroughly. The score uses the strongest observed deduction, so one panel is not penalized under multiple names. How interruptions are scored.

The type, and who can use it

Measured on 1 rendered page; latest measurement 2026-09-06. Every number is a mechanical fact about the page, not a judgment of its design.

WhatMeasuredThe bar
Body type size 15px, 15px at phone width 16px, the browser default
Characters per line 141 45–90
Line height 1.60 1.5 (WCAG 1.4.8)
Text contrast 4.9:1 4.5:1 (WCAG AA), 7:1 (AAA)
Text column 80% of the window at least 45%
Reflows at phone width no — scrolls sideways at 360px WCAG 1.4.10
Dark mode no noted, not scored
Automated accessibility checks 1 automated check failed (1 serious): link-in-text-block WCAG 2.1 A and AA, via axe-core
Keyboard no trap; focus visible on 79% of stops never trapped, always visible

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.

Measurement dates

Oldest evidence 45 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 3 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 Raw automated findings may have been superseded by later review or detector replay.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.

How we know

Pages rendered2
Site verdicterrors dropped; majority of remaining; ties to the stricter verdict; active reviewed exclusions override admission
Figures shownnumeric measurements generally use medians; interruption costs, overflow, keyboard traps and accessibility failures retain the strongest observed finding

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.
