What is the eCPM with a-ads?
The way our ad network operates you get a share of impressions which is related to your share of our daily budget. Clicks are not guaranteed because they depend on your ad (is it attractive, properly designed, etc.)
Let's say today we have 1 btc budget and your have set your budget to 0.1. That means you'll get roughly 10% of our impressions.
As for the number of clicks we receive daily, please check out stats:
