1 day is not enough to evaluate any network. Try it at least for 1 week since you have a good number of requests. Do you use only banners? Still the CTR rate(~0.09%) is horrible, most likely something is wrong with your app(ad placement, background…).
You need to stay patient (yet aggressive in testing) - if you’re looking to increase revenue.
The thing you really need to understand about ad networks is that the RPM/CPM/CPC/CPA always depends on the advertisers spending money with the network. So it is unavoidable - one day revenue will be great because a MAJOR advertiser decided to spend millions of dollars or Clash of Clans is spending loads to get people to install. However, the days that these advertisers stop spending is the day everyone will experience a drop. It’s just the nature of the business and a huge reason why there’s huge volatility day to day. It’s like trying to switch lanes in traffic jams - you see one lane going faster than yours so you switch.
Switching networks and trying new things is great - as long as you stay diligent and methodical in your approach.
