Would appreciate a general explanation of how Google Adsense determines the click rates on my eCommerce websites. Take 2009HDTV.com for example. I've been getting anywhere from 6 cents to $1.50 this month on individual clicks, varying greatly per each click. What puzzles me is that when I myself tried adwords out for this site, it would have cost me, minimum 50 cents to $10 a click, for various keywords. Why does there seem to be such a disparity between what I'm getting paid per click and what Google would charge me per click for adwords? Does Google take a set percentage for each adword or does that vary? I'd appreciate your input. Thanks
You are probably talking about minimums for google search or network. Those are ads that run on google search or partners like AOL. The content network are ads that display on regular sites running adsense. The bids are usually much lower because they don't convert as well and are prone to click fraud by publishers clicking their own ads. The $10 bids are because google doesn't feel the landing page is relevant, MFA, low CTR, etc., giving it a (low quality score). Google determines the value of the clicks on your site based on its content and how well it converts for the advertiser compared to other sites. If the people who click your ads aren't buying anything, then you get smart priced - the advertiser is charged less, and you are accordingly paid less.
