How is the current YAN coverage calculated?

Question

Yandex.Direct

Hello. Please tell me how the current coverage is calculated from the YAN rate
Here is an example

Interested in how 33% turned out on the second line

Answer 1

Coverage in YAN depends on the topics and platforms presented in this topic. For example, in the Auto theme, there may be ordinary automotive sites and the auto.ru portal (or the largest projects of other players).
They do not have equal conditions for participation in YAN in fact. You can’t get on auto.ru at a rate of 5 rubles, for example, but you can only get at 10. At the same time, conditionally, auto.ru generates 800 thousand impressions per day, and all other sites combined 1.2 million.
Then the rate for 100% coverage will be 10 rubles, the rate for coverage of 50% will be 5 rubles, but it is enough to raise it a little, for example, to 5.1 rubles and you can already get 60% coverage, but to make the next jump, you will need several rubles, because you need to bet enough to enter expensive sites, because. all the cheap ones you have already chosen.
Then there are topics in which there are no premium sites with special conditions, or there are almost no regular sites, or there are no advertisers, then it is possible that all 3 coverages: 20%, 50% and 100% cost the same. This means that you either come in and advertise or you don't.
In general, there is no single formula by which you can calculate the dependence of price on coverage, because everything changes depending on the subject matter, advertiser competition, site competition + Yandex does not reveal to us the whole inner workings of working with sites.

Answer 2

There is no strict linear dependence, you can only trust Yandex, if the dependence was linear, you could calculate it like this:
1) 50-20=30 - we calculate the percentage in the interval.
2) 6.1-4.1=2 - count the number of rubles in the interval.
3) 2/30 \u003d 0.067 - we consider how many rubles fall on one percent.
4) 0.067 * (33-20) + 4.1 = 4.97 we consider what cost should be at around 33%
or vice versa to find out the coverage based on the click cost 5.08:
5) 30/2=15 - we consider how many percent are one ruble.
6) 15*(5.08-4.1)+20=34.7 - we consider what coverage should be.
As you can see, the numbers do not coincide with what you gave in the example, this is just the same due to the non-linearity of the dependence of coverage on the cost of a click on YAN.
