AMP: Missing Non-AMP Return Link

AMP URLs that have a canonical non-AMP version that does not contain a rel=”amphtml” URL back to the AMP URL.

This could simply be missing from the non-AMP version, or there might be a configuration issue with the AMP canonical.

How to Analyse in the SEO Spider

View URLs with this issue in the ‘AMP’ tab and ‘Missing Non-AMP Return Link’ filter, and export all URLs using the ‘Export’ button.

The ‘Canonical Link Element’ column shows the non-AMP version that is missing the rel=”amphtml” back to the AMP URL.

What Triggers This Issue

This issue is triggered when AMP URLs are associated with a canonical non-AMP version that lacks a rel=”amphtml” link pointing back to the AMP URL.

For example:

https://www.screamingfrog.co.uk/amp/technical-seo/

References its non-AMP counterpart with the below canonical link element:

<link rel="canonical" href="https://www.screamingfrog.co.uk/technical-seo/">

But the canonicalised URL does not point back with the below ‘amphtml’:

<link rel="amphtml" href="https://www.screamingfrog.co.uk/amp/technical-seo/">

How To Fix

Ensure canonical and non-AMP versions of URLs contain a rel=”amphtml” link to the AMP version so they are discoverable and confirm the relationship.
