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 3 rendered pages; latest measurement 2026-10-07. Every number is a mechanical fact about the page, not a judgment of its design.

WhatMeasuredThe bar

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.

How we know

Pages rendered3
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
Speed varied1.5s to 27.6s across 3 pages, so we show the range rather than one number. A spread that wide usually means our measurement, not the site.

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.
