The URL in question is an AMP Page URL which is facing a Redirect (3XX) situation.
Why is this important?
Should an AMP Page URL be set to redirect, there is a risk that search engines will be directed to an unintended page. This may interfere with the correct indexing of the page or its visibility in search engine results.
What does the Optimization check?
This Optimization will initiate for AMP Pages that issue a 3XX HTTP status code in response to a request.
Examples that trigger this Optimization
Take into consideration the AMP URL: https://example.com/amp-version-of-page/
This Optimization would trigger if the previous URL returned a 301 (Permanent Redirect) status code:
HTTP/... 301 Moved Permanently ...
Additionally, other 3XX status codes tied to redirection would activate the Optimization.
How do you resolve this issue?
To ensure indexing, AMP URLs should not be involved in redirection. In such instances, the AMP URL might be redirecting to a different URL, possibly the wrong target. Redirects cause a delay for search engines which may lead them to disregard the AMP page or exclude it from results.
To solve this issue, verify the
<link rel="amphtml">
link is directed to the appropriate AMP version of the page and that it returns a 200 HTTP status, signifying availability to both search engines and users.
