Hreflang Missing Return Links

What This Means

Page A has an hreflang tag pointing to Page B, but Page B's hreflang set does not include a return link pointing back to Page A. The hreflang relationship is one-directional.

Why It Matters for SEO

Google requires hreflang to be bidirectional: if Page A (English) references Page B (French), Page B must also reference Page A. This mutual confirmation is how Google validates that both pages are aware of each other as language variants. A missing return link makes the hreflang signal incomplete and may cause it to be discarded.

What the Platform Checks

The platform crawls all hreflang target URLs and verifies that each target page references back to the source page in its own hreflang set. Fires when this return link is absent.

How to Fix It

• Add the missing return hreflang tag to the target page.
• Every page in the set must have hreflang tags for ALL other pages in the set, including a self-referencing tag.
• If the hreflang implementation is managed via templates: audit the template to ensure all language variants output the complete hreflang set including all counterparts.
