The main landmark sits inside another landmark
4.8%
of the 609 sites we scanned fail this
Ranging from 1.9% of EU e-commerce to 8.2% of Indian financial services. Pooled across five targeted cohorts, so treat it as a convenience sample rather than a rate for the web.
What it means and how to fix it
Main is the landmark people jump to in order to skip the navigation. Nested, it may not be offered at all.
The fix. Move the main element so it isn't contained in another landmark.
How often it fails
Share of scanned sites in each cohort. These are five targeted studies, not a random sample of the web, so read the contrast between cohorts rather than any one figure as a web-wide rate.

Groups smaller than 8 sites are not shown: a rate over a handful of sites moves by tens of points on a single result.
What this does not measureLimits of these figures, and where the corpus came from
- This rule maps to no success criterion, so a site failing it is not failing WCAG. It is still worth fixing: these are the patterns that decide whether assistive technology can navigate a page efficiently rather than merely read it.
- These are five targeted cohorts, not a random sample of the web. Per-cohort rates are the figure to quote; the pooled rate is a convenience sample.
- Denominators count sites that produced a result. Sites that were blocked or errored are excluded rather than counted as passing.
- Occurrence counts are floors: the engine records at most 25 occurrences of a rule per page.
- The EU and Indian cohorts retained only the primary success criterion per finding, so a rule mapping to several criteria contributes to one of them in those two cohorts and to all of them in the other three.
