Incorrect Language & Region Codes
What This Means
URLs with hreflang annotations that contain invalid language (in ISO 639-1 format) and or optional regional (in ISO 3166-1 Alpha 2 format) values.
What Triggers This Issue
This issue is triggered when hreflang annotations contain invalid language codes (based on ISO 639-1 format) or optional regional codes (based on ISO 3166-1 Alpha 2 format). For example:
https://www.getasky.com/technical-seo/ Has the hreflang annotation:
<link rel="alternate" hreflang="en-UK" href="https://www.getasky.com/technical-seo/" /> Where ‘en-UK’ is not a valid regional code, and instead should be ‘en-GB’.How To Fix
Update hreflang annotations to include valid language and regional values, so they can be used for geotargeting the right audiences appropriately.
