What's the use of guessing or saying something when they have a special group with their entire price list. Don't be lazy and look at it, buddy.
I will add to the answers that the owners of the MDK own a dozen other VKontakte publics, where there are over a million subscribers and advertising on average costs about 5-15 thousand rubles per post.
In short, advertising business in communities - quite a profitable thing.
Do not forget that teams like MDK own whole promotion companies that have up to 10 large millionaires in use and the budgets there are very solid. ZY everyone can go to the VK advertising account and see statistics, prices, etc.
I agree with Andrey and Ivan. To be honest, their audience is very poor, this is due to their theme. In general, they earn a lot, since advertising posts are expensive, but if you decide to order advertising from MDK, then get ready for such an audience.
When I last found out, the cost of placing on a public page increased from 15 to 80 tr. (For one post). Perhaps more expensive now. Just count the number of advertising posts, and multiply by 80-100 tr. for each one.
By the way, when I once posted there, it turned out (and what else I expected) their target audience is terrible, it's really a bunch of fucking schoolchildren. So it is profitable to mix only all kinds of toys, etc. and guys who have nowhere to do with advertising budgets
Advertising is the engine of progress, as you know. According to Wikipedia, in 2013, the daily attendance of the MDK public was 12 million people, and the net profit was $ 1.3 million (!!!) per year.
Earn on advertising. Almost all popular publics are created for this. The larger the audience, the higher the cost of advertising posts.
