## What it means

One of this page's hreflang tags has an invalid language/region code or a link that isn't a full web address, so Google ignores that tag and shoppers may land on the wrong regional page.

## What to do

Usually a Markets or translation app change. Check the tag's language code and link, then fix whichever is wrong. Rabbot re-checks automatically and will confirm when it's fixed.
