The fact that an advertiser bids for $80 or something doesn't mean they are going to pay that much for any click. They raise the bid to get ahead of the competition but at the end of the day they pay that much only once in a while. Perhaps less than half of that number in average.
It is the higher of the paying keywords, notice the all have 1 thing in common, see if you can figure it out it is simple
If you want revenue don't look at high paied KW, because you will never come to first page. Some one else have done it before.
Hi, I think they have got mixed up with CPM (cost per 1000 impressions) and CTR. Your website content must be good and keywords must match your content for adsense to work for you. An example of keywords and costing can be found at highpaidkeywords.moonfruit.com You CAN achieve these payments but please concentrate on your CTR and not as much on keywords itself. I hope this help.
