As a publisher, your revenue depends on the fill rate and CPC (or CPM). if you run campaigns from the admob network, under the CPC model you pay with a click. You can set a short update time, although it barely affects the number of clicks, it has a negative effect on your fill speed. The Admob network engine is smart enough (like the others) to serve these stocks with better performance.
if you join the RTB market, you probably want to split the ad units in different activities. Thus, you can transfer various metadata or attributes (for example, the ad unit is located on the sports content page or on the cosmetics page) to ad units, which greatly affects the actual price of the buyerβs participation. As a publisher, if you want to maximize revenue, try passing some user information to an ad unit, for example, geographic location, if any, or gender, etc ... impressions with the data are of the utmost importance.
