Retargeting Primer

What is retargeting?

Retargeting means showing a user advertising for a product that they’ve looked at in the recent past. Retargeting, from a users perspective, is broken down into two stages: In the first stage they’re looking at a product or service at the product’s web site. In the second stage they see ads on (possibly unrelated) web properties for the product or service they were looking at previously.

Daily and Global Cap Primer

This is the second part in a series on The Basics of Online Advertising. I’ll be posting a new entry each week for the next four or five weeks.

What are the Daily and Global Caps?

The Daily Cap is the limit of the number times an ad is shown throughout the day. With branded campaigns these are usually in the 10s or 100s of thousands. When used on a performance campaign it can vary based on the confidence in performance for the given targeting parameters. When the cap is achieved the ad stops serving. The next day the ad starts serving again until it reaches the daily cap once more.

The Global Cap is a bit of a misnomer. It behaves as the limiter for the entire campaigns impressions from beginning to end. Once the global the ad stops serving, period. It doesn’t start up again the next day. In ideal circumstances the global and daily cap are harmonious so that the daily cap was restrictive enough, but not overly restrictive such that the global cap was reached or nearly reached on the end date of the campaign. Mathematically speaking – an ideal daily cap is equal to the global cap divided by the number of days in the campaign.
