fc.lc is a highly popular url shortener from Morocco. It has relatively high rates, but in my opinion their monetisation strategy is flawed, because they use only AdSense partners as monetisation.
AdSense Partner Banner from Redmas.com x4 - $1 (CPM)
PopUp from Adshort.media x2 - $1 (CPM)
PopUp from PropellerAds x1 - $0.3 (CPM I think)
The second page matches this one, there is the same amount of ads with same earnings.
Altogether, the earnings are approximately $4.6 per 1000 worldwide views.
RPM - Earnings from Clicks and CPM in ad networks altogether per 1000 impressions.
CPM - Earnings from just views and no clicks per 1000 impressions
CPC - Earnings for 1 click
CPA - Earnings when someone completes an action such as a signup.
