Conflicting hreflang entries

Error severity, in the Hreflang tab

Why it matters

The same language code points to two different URLs on one page, so search engines cannot tell which version to show.

How to fix it

Keep one URL per language code; remove the duplicate entry.

How Crawlune finds it

Crawlune flags Conflicting hreflang entries automatically on every crawl and lists the affected URLs under the Hreflang tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 550 URLs with every check enabled.
