About This Check

Checks whether a viewport meta tag is present for mobile-friendly rendering.

Why This Matters

LLM Discoverability

The viewport meta tag has no direct bearing on AI content extraction, but its absence is a strong indicator of poor mobile optimisation, which correlates with lower content quality signals overall.

SEO Impact

Google uses mobile-first indexing; a missing viewport tag triggers mobile usability warnings in Search Console and can result in the mobile version being deprioritised in ranking.

What To Do Next

8.4% of audited sites need attention on viewport (50 of 596 sites are warning or failing).

Prioritize viewport on templates that create many URLs, because one template fix can improve a large share of html extractability & main content clarity.
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 91.6% pass rate as a benchmark: if your site fails here, passing the check moves it closer to the visible majority of crawlable, AI-readable pages.
