it depends on the content of your site. BEcause according to the content the ads will get placed. I will put some highest paying keywords later which pays from 5 to 20 dollars a click.
I havent seen any niche where you can get that range though. The person should be very confident of his ROI for 5-20 USD per click if he pays you
Yes it's very much normal to get $0.10 or less than that. Your EPC or earning per click depends on the quality of eCPM which is again the result of CTR, page impression and the amount an advertiser has actually bid for keywords while making content match option on. I do not deny the fact of getting $5 or even $10 per click but those are not usual case and possible only when your website content is related to some highly competitive segments such as mortgage or education where bid goes as high as $45-$50 on certain keywords.
