You got that right. The click came through my corporate flight attendants site which deals with business aviation. Today, that niche is so saturated and nobody is paying the big $$$ for clicks as they have wised up!
I am still trying to figure out what all those google stats mean. I set up my channels to see where the clicks come from and how much I am earning and that's about it!
Only a few dollars for me, but then again, I don't use Adsense anymore...and haven't since around a year ago or so.
Google determines the click trough IP Address and Geo Location. The click Rate depend on keywords and Location . Its depends on the amount of money Advertiser Bid for Ads from that country . My highest was around $7 for insurance
