Yandex targeting, or how to find out the visitor's commercial interests, gender, age?

Question

API

When a visitor enters the site through an advertisement, it is possible to find out which company he came from, which ad, which city he is from. Is it possible to find out his commercial interests, his age and gender, perhaps somehow through the API metric

Answer 1

I subscribed to your question, but I see that no one is torn with answers. I will share what I know.
At the expense of gender and age - Yandex has Crypt technology, a cat. using machine learning determines the gender and age characteristics of customers. In fact, it is a symbiosis of advertising preferences with behavioral factors. You can view the corresponding report in Yandex.Metrica. This is the Demographics report (Visitors - Demographics - Gender and Age, step by step).
Commercial Interests: Visitors - Interests - Commercial Interests.

At the expense of companies, as I understand it, you mean Direct companies? Then there is nothing difficult. The simplest thing is that you can link it with Google Analytics by goals (but you need to link it, because each counter "lies" in its own way, because there are always errors in those tools).
