I am receiving a warning from Google:
Search Console has detected that your website is affected by 1 problem(s) of the “page indexing” type. The following issues were found on your website. We recommend fixing these issues if possible, so that Google Search works optimally and has a high reach.
Most common issues: Duplicate - not set as canonical by the user
I have no idea how to fix this, nor what the problem is.
When I click “Troubleshoot”, I get this message as a response:
Google has begun reviewing your troubleshooting of page indexing issues on your site. Specifically, we are looking for “duplicate - not set as canonical by user”. There are currently 1 pages affected by this.
I don’t have duplicate content though.
What is bothering Google here?
Any advice is very welcome.
p.s.: the results after searching for “canonical” in the posts did not help me.
