Impressions drop on google. In Yandex, the quality is not enough. CHADNT?

Question

HTML

CHADNT?! :(

In google, the number of page impressions in search queries is falling. Although the amount of content and pages, on the contrary, is increasing.

Yandex today generally issued that the last added page ( https://ForexApps.ru/nav/post/... ) is of insufficient quality and excluded it from the search. Google indexes it, although I couldn’t find it in the search, apparently something is also wrong.

The site was written in PHP using Bootstrap 4. Maybe I did something wrong with the tags so that search engines cannot index the content normally? Something tells me that something is apparently wrong with the tags, apparently the content itself needs to be wrapped somehow differently. Who could look and suggest what is wrong? :(

PS Do not judge strictly. I'm a beginner, and only at the beginning of the path:) I will be glad for any hints.

Answer 1

Express audit showed that you have a small number of duplicates in meta tags, but it's not scary and you don't live with it. Didn't look at the code.
According to the text on the specified page : only the 1st paragraph is repeated, exactly the same is on the Main page. It is advisable not to produce internal duplicates of content.
There are 24 HTML pages on the site in the Yandex/Google search results, almost the same number. But the problem is not in this, but rather in the total number. For more traffic you need more pages. How to understand how much? Look at how many pages competitor sites have for promoted queries, display the average and it will become clear. This may be one of the reasons for the lack of traffic.
Why Yandex considered the page to be of poor qualityand thrown out of the index: Yandex itself explains this by the fact that pages optimized for requests with a frequency of "0" will be thrown out of the index until the frequency rises. I can’t give a link to this Yandex statement, it’s a long search, but you can find it through the search if you’re interested.
So, the page you indicated is most likely optimized for a microfrequency request that no one is requesting now:

Maybe it's the content? Tags, layout are not as important as the content itself. Is this copypasta?

Answer 3

Because Yandex had a failure on April 24, which led to the release of a very large number of pages on many sites. Now everything should settle down. If the problem persists, then throw a link at me.
