Will the cost of a click in direct go down if the keyword accuracy is high?

Question

Yandex.Direct

Good afternoon.
There are 2 requests from customers: 1. Buy an iPhone - for 100r per click and 2. Buy a black iPhone for 50r per click.
I have an ad with the only key phrase "Buy iPhone"
The client entered in the query "Buy a black iPhone", he naturally thought of my ad, because it fits, he clicked.
How much money will I have? 100 or 50 rubles?

Answer 1

Roughly speaking - 50 rubles, since the ad will participate in an auction with advertisers on the request "buy a black iphone" and if you are sure that in this auction the price to be charged will be exactly the same for the amount of traffic you are applying for, then exactly this price will be charged the price written off, not the rate you set.
Also consider the possibility that competitors will impose bid adjustments that could affect the auction. The presence of adjustments in your campaign that may increase your bid, but give you a higher position. Also take into account the work of Yandex's optimization algorithms, which can arbitrarily increase your bid if they consider this user to be a very conversion rate for you.
