Why we check this
We check this because unresolved technical issues can silently block Google from crawling, rendering or indexing your pages at all — no amount of good content fixes a page search engines can't reach in the first place.
How it's checked in your audit
In your seoaudits.ie audit, this is checked as part of the Technical SEO pillar, using crawl data, log files and manual verification.
A common issue we see
One-directional hreflang tags — where the UK page points to the US page but not vice versa — are one of the most common hreflang errors.
How to fix it
Validate that every regional page references itself and links back symmetrically to and from all its alternates.
