Please don’t worry it’s not an issue it’s just a notice from Google as the main pages get indexed and google bot found the two URLs of the same canonical that’s the reason one page gets index and one page get excluded.
So I recommend you to please ignore this notice.

That’s it for this tutorial!
We hope it helped you. If you have any feedback or questions, then please share them in the comments section below.
Hi,
My Website is “https://www.helixengineering.co.in” I am getting more excluded warning in coverage issues “Alternate page with proper canonical tag” . That why still now no index my URL in google search engine. All product pages are live but not indexed in Search Engine. Please give the solutions. We applied the redirection for old URL & no index robots tag given in old URL.
Sample Product page is “https://www.helixengineering.co.in/rubber-products-manufacturer-and-seller/neoprene-o-rings”
Please sort out the problem.
