Hmmm, I find this very intriguing. My site gets around 750 clicks (daily) with Adsense and makes a hefty chunk of change. But I only get 6 clicks with my WidgetBucks ads in the hotter spots on my site. Kinda gets you wondering.
Different programs will filter clicks differently, they have different fraud filters etc. Although that is a large difference.
I have noticed a similar drop in clicks between my adsense and widgetbucks but I think it is because the style of the ads. Adsense is much easier to blend and fools your users into clicking a lot of the time...whereas widgetbucks are just blatant ads.
728x90 3,276 3 0.09% $0.12 $0.36 300x250 4,035 6 0.15% $0.11 $0.66 My Widgetbucks stats of yesterday.
The same has happened with me... I get around 15-20 clicks per day... but with widgetbucks the clicks since last 3 days is 0. I can easy see that that ads 100% match the content of my site. SO what can be the issue?
