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 3 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 2026-09-05 — no article measured yet. Every number is a mechanical fact about the page, not a judgment of its design.

WhatMeasuredThe bar
Body type size 14px 16px, the browser default
Characters per line 21 45–90
Line height 1.50 1.5 (WCAG 1.4.8)
Text contrast 7.0:1 4.5:1 (WCAG AA), 7:1 (AAA)
Text column 15% of the window at least 45%

Dark mode no noted, not scored
Automated accessibility checks 2 automated checks failed (2 serious): link-name, list WCAG 2.1 A and AA, via axe-core
Keyboard no trap; focus visible on 100% of stops never trapped, always visible
Structure no main landmark, 1 h1, 2 skipped heading levels a main landmark, one h1, no skips
Alt text 80% of 15 content images described 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.

Why it is excluded

GateWhat tripped
G1Hard paywall — the content requires payment

A site that fails any of these is not indexed at all — not ranked lower, absent. It keeps this page, and the measurement that produced the verdict stays visible.

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 Raw automated findings may have been superseded by later review or detector replay.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.
