Case a second price auction is valid. The way it works is that the advertiser with the highest bid wins. But what is deducted is not the specified rate but the competitor's rate (second price) kopecks. Advertisers get maximum results at optimal cost. The minimum spend strategy also applies to second price auctions. The advertiser sets the maximum bid he is willing to pay. At the same time the system attempts to use the lowest rate allowed by the competition and never.
Exceeds the given allowed rate. algorithms to determine the winning last database ad. The system calculates the total value of each ad based on several criteria: advertiser bid; audience response; ad's relevance. At the same time, the total advertising value and the relevance score are not the same indicators.
The latter can be seen in the advertising account which is a simplified assessment of the value of advertising. It allows the advertiser to understand the effectiveness of the ad but this number does not affect the display of the ad. Relevance score is a perfect score determined after ad impressions. Bidding is automatic. The system determines the lowest rate that will allow you to spend your specified budget during the selected campaign period.
