"?no redirect=true" started appearing in Googe Search Console

[etibv]

On google search-console, I was notified - "Duplicate without user-selected canonical", which refers to pages on my site that have the extension:
?no_redirect=true
I don't understand, it's unclear, from where and when this extension "popped" into the site pages ? And what should I do with it?

Hi etibv and Welcome to WebmasterWorld [webmasterworld.com]

If you are certain that these pages do not exist then I would say to ignore them. Many others are seeing similar type problems recently. I've seen some of my own that don't exist. If I try to "inspect URL" it is not found. Personally, I think that they are still working on the "new" GSC since it was new.

Another discussion here that is similar: [webmasterworld.com...]

one option you may have (possibly the easiest to implement) is using the URL Parameter tool [google.com] in GSC.
(see: Block crawling of parameterized duplicate content [support.google.com])


the preferred option would be to implement a 301 redirect from the ?no_redirect=true url to the same url without a query string.
assuming you're on an apache server you could ask these questions in the Apache Web Server forum [webmasterworld.com].


another option is to implement an appropriate link rel canonical [support.google.com] element in the header of your document.

Welcome to WebmasterWorld, etibv!

Thank you.
I will implement the canonical URL.
