I never got a chance to have such a big CPC. I've also tried many keywords but not use. And i finally realized that if we have a US/Canada clicks on such top paying keyword ads then we are able to generate the big numbers as you said.
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.
In what niche you are sadek? We cannot expect to get that much since this is how much advertisers pay and not how much we get from adsense, anyway I have never got more than 2$
I was not able to track the post where the click was made. Check it here: http://www.maxblogtips.com/earned-23-56from-adsense-for-one-click/ NB: there was a typo in my first reply, the amount is $23.56
I guess the cpc of 17.31 is not from a US visitor, if it was US visitor clicking on the ad then i guess it would be around $30+
$ 55 per click???? It is very hard to believe. Did anyone get more than $ 10 from single click from adsense over here???
