I know I am very new to this "game" but many times Adsense does not make sense at all. I have seen most of the Adsense Ads competing with the website's content and many times those competitors take away sales from you by literally giving pennies to you !
Adsense can only make sense if your content is optimised for heavily searched . Also, it is not enough to just display the ads you have to increase your CTR. Check this site out ... to help you
( I hope this is okay Lynn these happen to be my affiliate links, if not please delete, and guys you can check the links for
Top Paying Keywords ... and
Triple your Adsense CTR ... in my signature. Thanks )
Also it makes a lot of sense to have adsense style Ads but only of affiliate programs you are promoting.
So you have Adsense Optimised Content so that you get ads for , You have applied the techniques to and you have Adsense Style Ads to Promote Your Affiliate Programs.
So one can take "MAXIMUM" Advantage and have multiple income streams !
... just my 2 cents
