Why is the page not showing up for a search query?

Question

Search Engine Optimization

Hi, such a problem, I don’t understand how to solve it for 2 months
there is a site for the sale of cars, there are several dozen pages.
Main page - car sales in Moscow, on this page in the car catalog there are both ordinary cars and several trucks, about 10 pieces.
Then there is a page purely for trucks, there are already about 15 trucks only in the catalog, and in general the word trucks is much more common than on the main one.
And it turns out such a problem that on request the sale of cars in Moscow, that on request the sale of trucks, the main page is shown in the search.
For the 2nd month I have been trying to edit the page on trucks for everyone, so that it finally starts showing up on requests, but to no avail.
I’ll also add that to the page on trucks: I
bought 5-8 good trust links,
the design of the site is not worse than competitors, the
behavioral factors are good
The page itself is in the index, but when you drive in the query “trucks in Moscow”, the main page of the site is shown, and there is no page that is designed for trucks in the search results (I scrolled through at least 10 pages, it was not there)
Maybe someone understands what the problem is and how to solve it?
PS: when I was making the main page about clustering, I didn’t know yet, also the main page has an age of about 1.5 years, and all this time the page has been in the index, and the page for trucks has an age of 2 months (maybe somehow affects)

Answer 1

When checking, specify the site parameter simply, it is obvious that you are just checking crookedly

Answer 2

Is the url directory structure built on a hierarchy?
Of course, two pages of the same site will not be shown in the search results.
Remove occurrences of cargo from the main.

Answer 3

Check whether Yandex ate the page with cargo in principle, remove entries on the main page, carefully place links from the COP to the desired page on the important pages of the site.
