Why does Yandex Webmaster consider pages of insufficient quality?

Question

Search Engine Optimization

Over the past three days, Yandex has removed several pages from the site from the search and, apparently, continues to do so. And this is not about SEO-water, but about technical longreads that I translate from foreign sites. For example, here and here . I checked the post with the RankMath SEO plugin - it rates the page at 91 out of 100. The text is long (>2000 words), text.ru says that the text is unique.

What can be wrong?

Answer 1

- in the domain
- in the general structure of the site
- in SEO re-optimization
- in competitors, which Yandex considers the standard
... and so on and so forth

Answer 2

Look towards fixing internal duplicates on the site.
Example:
lvsolutions.ru/h265/
lvsolutions.ru/arts/video-art/h265/
