Why landing pages without meta tags can be at the top of Google search?

Question

Search Engine Optimization

There is a topic - a driving school in Vitebsk (a regional center in Belarus). Why, for example, does a site like this vit-avto.by usually have positions in Google only on page 2 for targeted queries (driving school in Vitebsk, driving school in Vitebsk), despite the fact that other landing pages, as far as I can tell, do not even mention there is no optimization (no meta tags). How is this possible?
Maybe they have some sort of robots.txt or sitemap.xml file? Can they influence it? I am confused.
I’m not very good at SEO, I’ll say right away, I myself am a programmer by profession. Maybe this case will be of interest to SEOs

Answer 1

Now search engines rank by a hundred factors and not only by meta tags
, not the nineties

Answer 2

Google for some behavioral should throw out this vit-avto

Answer 3

And why robots.txt or sitemap.xml for a one-page site? :)
At least the title has a query entry. Therefore, I would not say that it is completely without meta tags :)
