Repeated hreflang code: Raptor SEO check

What we look for

The hreflang tags (lines in <head> listing the page's versions in other languages) on these pages use the same language code more than once.

If the repeated code points to different addresses, search engines cannot tell which one to show for that language and may ignore both.

Keep one hreflang tag per language code and remove the extras, in the page template or the plugin that writes the tags.

Raptor flags a repeated code whether or not the tags point to the same address.

The id is stable, and every surface uses it, so it’s the thing to search for or hand to an agent.

Terminal: When it is one of the five findings under Fix first, raptor crawl prints the id under it.
Check: hreflang.multiple_entries
crawl.json and the CSV: The crawl JSON names the finding by this id, and so do the CSV and raptor_query.
"check_id": "hreflang.multiple_entries"
The HTML report: This link opens the finding in the report, and each finding shows its id.
crawl.html#finding=hreflang.multiple_entries
MCP: raptor_findings with this check_id returns the finding in full, with a fix brief ready to paste into a task. If it didn’t fire, it says why.
raptor_findings { "job_id": "...", "check_id": "hreflang.multiple_entries" }
