Traditional methods for Optimizing eCPMs

Waterfall Mediation – Waterfall mediation is an aging advertising system that works as a yield optimization model, delivering ads from networks depending on their past eCPMs. For each ad request, ad impressions go from one ad network to the next, from the highest projected CPM to the lowest.

In-app Bidding – In-app bidding is a sophisticated advertising technique in which publishers can sell their ad inventory in an auction, allowing all of their advertisers to compete in real-time for impressions. Because of the intense competition, the publisher’s prices are much higher. This technique effectively enhances fill rates, and as a result, eCPMs.
