How do ad units work?
The ad units provide the publisher with information on the ad format, and when the publisher publishes the ad formats suitable for the placement that has been requested, the ads begin to run. While it may seem that choosing an ad unit is sufficient, there is also the requirement of selecting an ad format, ad type, targeting, etc., to ensure that ads run correctly.
