Question

Search Engine Optimization

Hello, in the duplicate pages identified by Yandex, I noticed pages that are completely different in content and url, the pages are not yet filled with sufficient content and description, is this the case?

Answer 1

I would like to see a couple of links to the pages.
Look at the titles of these pages, are they different?

Answer 2

And how can they not be filled enough if you say they have different content

Answer 3

For example, these robot identified as duplicates.
https://buroshop.ru/product/komplekt-videonablyude...
https://buroshop.ru/product/trubka-grandstream-dp7...
But these are non-canonical, although one of them has the tag:
https: //buroshop.ru/product/samonabornyy-shtamp-tr...
https://buroshop.ru/product/samonabornyy-shtamp-tr...
