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.
Why it is excluded
| Gate | What tripped |
|---|---|
| G1 | Hard 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 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 Raw automated findings may have been superseded by later review or detector replay.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 rendered | 3 |
|---|---|
| Site verdict | errors dropped; majority of remaining; ties to the stricter verdict; active reviewed exclusions override admission |
| Figures shown | numeric 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.
