About This Check
Checks the rendered page for a main, article, or role="main" landmark containing the primary content.
What To Do Next
39.4% of audited sites need attention on semantic main landmark (1,199 of 3,040 sites are warning or failing).
- Prioritize semantic main landmark on templates that create many URLs, because one template fix can improve a large share of the relevant audit section.
- After changing the page, re-run the audit and compare the observed value for this check instead of relying on visual inspection alone.
- Use the 60.6% pass rate as a benchmark: if your site fails here, passing the check moves it closer to the majority of crawlable, AI-readable pages.

Key Insight
The largest gaps are content metadata and trust signals: only 7% to 11% of sites include visible or structured dates, testimonials or case studies, and cleanly organized rendered DOMs. In this baseline, core security and server configuration checks are universally met, while page-level content quality and machine-readable publishing signals are much less consistent.
