Recently, I've signed up for all three of these programs (actually, used google for a while, then signed up for Chitika, then YPN. I have been rotating them for all of December, and I have around 4000 Page Views/Day. Now, here's my question: is it overkill to have all 3 of these? I have a low CTR (less than 0.1%), because my site is a forum. Also, weirdly, I noticed that on a day I got digged, and got 12,000 page views (my site went over bluehost's stupid CPU quota, so got removed), google got a CTR of 0.6%, Chitika, NO CLICKS, and Yahoo, 0.05% CTR. This month (so far), I've earned $25.13 from google, $8.59 from Chitika, and $8.91 from Yahoo. All are balanced evenly, impressionwise. Now, here is my question: it seems logical that if I remove my Chitika ads and Google ads from my webpage, my google ads revenue would triple or more (according to Dakait, "Income Per AD= CPC x Fractional pay out x CTR x Page Traffic x Appearance Frequency.") But will it? Or is having the multiple ads increasing my click through rate by introducing more variety? Which ads should I keep? Which should I remove?
do you have any problems running into the TOS or violations if you would have all 3 on the site at a time? just wondering because im planning to soon use another ad service for my site along adsense
