95% confidence interval: 98.2%–100%
About This Check
Checks whether hreflang tags are present for multilingual or multi-regional pages.
Why This Matters
LLM Discoverability
hreflang tags tell AI language models which URL to prefer for a given locale–language combination, reducing the chance of an AI returning the wrong language variant to a user.
SEO Impact
Correct hreflang implementation prevents duplicate content penalties in multilingual sites and ensures the appropriate language/region variant ranks in each target market.
What To Do Next
Every audited site in the current sample passes hreflang, so this check is currently a baseline expectation rather than a differentiator.
- Prioritize hreflang on templates that create many URLs, because one template fix can improve a large share of trust & security.
- 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 100% 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.
