Do You have Low Adsense Click-Thru Rate??? Try this...
 

As you know Google treats different accounts differently...ultra-high earning affiliates get perks most don't. But that being said somethings can be done if you have relatively high traffic, yet a very low click-thru rate (sometimes they do this on thier own) Shoot an email to adsense explaining how your site get ligitimate and genuine traffic yet yeilds a very low click thru rate (it may take a few dozen emails even if you got some primo hook-up in there - they just got a corporate culture like that where support is pretty weak) but they will eventually for their own interests investigate your account and adjust to ads that may not be as relevant yet fit the site user demographics - and this can make a whopping difference. You can also do much of this withn your own adsense account - but I still find it tricky to get it just right..

Thanks for the tips, what do you suggest would be a low enough CTR to make it worthwhile to contact them?

Good info to know!

this really works?? i think it is not that so simple!

Never heard that before. Makes sense though, it is in their interest too.
Be curious to know if anyone else has done this and had success.
