Vladislav Ulendeev about traffic with Yandex.Market

To liven up the group, I’m posting the answer of the executive director of the eHouse holding, Vladislav Ulendeev, who was not included in the interview.

For all its power, eHouse practically does not use traffic from search engines, while all other online stores literally sit on traffic from Yandex.Market.
I asked Vladislav why eHouse does not participate in the Market, and this is what he replied:
The answer is simple. The rest do not know how to count the effectiveness of advertising on the Yandex Market. Advertising on Yandex is not effective. And there are no other reasons not to advertise there. We are able to calculate, with an accuracy of up to a cent, the effectiveness of advertising per visitor and per source Also, you are wrong about the fact that we do not advertise on search engines. We are actively advertising on Google. From it we get real buyers, not robots, who click on the link in the “Market”.
We tried several times. But the result of working with the “Market” is pitiable. And do not look here for pitfalls. They are not. Just expensive and not effective.

So, how true is the assertion that advertising on Yandex.Market is not effective?
