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.
1st Page:
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.
