Why does the site dislike Yandex so much?

Question

Google

Hello comrades!
I have one site lilium-center.ru
Site of a psychologist, market, respectively, local - urban.
The site should be located on a request like "psychologist in [*city name*]", etc.
In Google - in the first places, in Google maps - under the letter A, everything is ok.
In Yandex - 24 - 30 place, in the maps it is not visible at all.
At the same time, nothing was done specifically for Google on the site. For Yandex, both the metric was set and the direct was given. At one time, links in Sapa were purchased. All to no avail.
A little about the site:
by age - about 5 years old;
- I update the content weekly, add news, sometimes articles;
- the texts on the site are mostly unique, and everything else is rewriting;
- the main page is all unique;
- there is no engine, the database is not used, the response time is very fast (checked through services);
- Titles, metas on each page are different, headings highlight everything you need;
- Webmaster from Yandex is connected, the region is set;
- Phones have a city code, the name of the city is also written;
- Down site is extremely rare, 3 times in 5 years;
- Black SEO methods didn't seem to be used (I'm not sure about links, but it was not for long and the situation was the same before);
- Site map is, updated;
- Indexing in .htaccess is not prohibited;
As a result - attendance only from Google, groups in VK and direct visits.
See what else can be improved?

Answer 1

Perhaps Yandex users from Rostov-on-Don do not need the services of a psychologist. Grow the direction of Google.
UPD: Yandex "does not love" you for a small TCI (10). The solution is to slowly increase the TCI (link building).

Answer 2

Eh, it's required. And sites from the top from Yandex customers come.

Answer 3

You were right in the comments. Buy links and add content to the site. Link inside tighter.
At the same time, give context (not too much) to increase user factors (traffic, time on site, depth). By August, catch up if you start today.
ps
I recommend that you think over the content plan, the volume of links and context IN ADVANCE and approve it with the customer so that there is no "let's do it again!" later.

Answer 4

The same story with my blog 3mu.ru , there is search traffic from google, but few from Yandex.
