Inconsistent Hreflang Return Links

What This Means

The hreflang return links from language variants point to different URLs than the source page expected. For example: Page A (en) points to Page B (fr), but Page B's hreflang points back to Page C (a different en URL) instead of Page A. The hreflang set is internally inconsistent.

Why It Matters for SEO

Inconsistent return links indicate that hreflang was not implemented consistently across all language variants — perhaps because different CMS templates or plugins are managing hreflang for different sections. When the cross-reference URLs don't agree, Google cannot build a consistent picture of the language-equivalency relationships.

What the Platform Checks

After crawling all hreflang target URLs, the platform cross-references which URLs they point back to. Fires when return links do not match the originating page's URL.

How to Fix It

• Identify the source of inconsistency: which template or component is generating the mismatched hreflang URLs?
• Ensure a single authoritative source generates hreflang tags for each page based on a consistent URL mapping.
• Rebuild the hreflang implementation from a canonical URL mapping table that all templates draw from.
