Is there a connection between low-quality pages and positions on the site as a whole?

Question

Search Engine Optimization

There is an online store with a bunch of product pages. Yandex mows down hundreds of product pages as low-quality (700-800 pages per day). Positions on average around the top 30 hang out. The question arose, could it be that, due to a bunch of low-quality ones, Yandex crushes the main pages or low-quality ones and the positions of other pages are not connected?

Answer 1

Algorithms evaluate too many factors to give an unambiguous answer. Probably there is taken into account the number of low-quality pages. Try to figure it out. Too many a day to ignore

Answer 2

Classic for online stores. Well, for reasons:
1) Yandex itself is not particularly picky and can, instead of removing a duplicate from the search, mark both as low-quality. But at the same time, this will not affect the issuance of other, high-quality pages of the site in Yandex, unlike Google.
2) The quality of the content on your pages and low-quality SEO links placed on other resources can also affect.
3) Which pages are marked as low quality? Maybe these are pagination pages or with different get-parameters?
4) Did you by any chance recently migrate from HTTP to HTTPS?
But I’m more than sure, since you have an online store, that the problem is in non-unique title, description and headings (h1, h2) + since you have so many products, then most likely the product cards are filled with poor quality. I advise you to compare these parameters of several low-quality pages with each other, and there you will get the reason.

Answer 3

What have you done to promote quality pages? If nothing, then the question is meaningless.

Answer 4

There is a connection because search engines rank pages in the context of the entire site. That is why, if the whole site is shit, licking a separate page is ineffective.
