A frequency cap is a function that allows you to set the maximum number of ads a customer will see in a certain time period. Such as 3 ads per hour, or 10 ads per 12 hours etc.
While this cap is in place you might see a couple of extra ads if you are rapidly refreshing your page. Why this happens is that we bid across multiple exchanges and an impression might be served before the other one is counted down. We do not see this happen often, but in general, it doesn't alter the overall performance of the campaign. In all frequency, caps are loose rules and are not guaranteed but the system usually hits pretty close to the mark every time. With the knowledge, it is highly recommended that when setting up a campaign consider the audience size and the brand. At a minimum, 3 ads per 12 hours should be the least you do, we also do not recommend leaving a cap off because the system will then try to serve as many ads as it can win and you might "banner spam" your potential customers.
