Adserver.Online chooses ads for display from the set of ads assigned to a particular zone. And ads prioritisation is a way to influence that process. Here are the options:
- Top rate
- Second rate
Firstly, we will talk about Weight and Rate options. They are very much alike and both use weighted-random logic.
Therefore, every campaign/ad has a chance to be displayed. Users are able to adjust the probability of that via the Weight property in their settings. Besides, you can use a campaign's Rate as Weight in case you find it more suitable for your business.
Top Rate method means campaigns/ads with the highest rate will always win the auction. In this case, lower bidding campaigns/ads may not receive any traffic (subject to frequency capping, limits, and traffic volume available).
If you select Second Rate, the winner of an online auction is the one who makes the highest bid, but the sale price does not equal the bid. Instead, it equals the previous bid of the competitor. If your bet is, for example, $2, and the previous competitor has set $1.5, then you will be charged $1.5, not $2, as is the case Top Rate.
Top Rate and Second rate options were implemented for RTB/XML-feed integration in particular. Therefore, we don't recommend using it on usual zones and ads unless you have a complete understanding of how it works.
How to configure ads prioritisation
In order to select one of the prioritisation types, you should go to zone's form in Advanced section:
Besides, you can set ads prioritisation manually for each zone. Another way is to set its default value in the Settings menu.
