What this is
A rolling aggregate of completed website scans. It is built from the same six-basic scoring model used in every individual report.
What it measures
Higher scores mean fewer blockers across speed, findability, accessibility, trust, action and credible copy.
What it is not
It is not a list of every site on the web, and it does not publish private scan reports. Public numbers are aggregated.
How to read the score
Higher is better. The score is a readiness score, not a shame score. It asks whether the site is ready to do its job across the six basics.
How to use it
If your site scores below the Index average, the question is not whether the site is embarrassing. The question is which basic is costing attention, trust or action first.
If your site scores above the average but below the top quartile, the opportunity is usually a focused cleanup rather than a full rebuild.
If your site reaches the top quartile, keep monitoring it. New AI-built websites, new browser behaviour and new content patterns move the benchmark over time.
Distribution
Quartiles show where a scanned website sits against the current sample. A score of 72 means more if the median is 58 than if the median is 74.
P25
A quarter of sites score at or below this.
Median
The middle of the sample. Half score lower, half higher.
P75
Top quartile starts here. This is a useful improvement target.

Builder signals
The scanner detects builder fingerprints where it can. We publish builder-level rankings only once there are 30+ recent samples, so early rows should be read as directional diagnostics.
