I started testing adwords for the first time and definately the traffic has increased on those sites which I advertised through adwords. My adsense income has also increased. In fact, the traffic and my adsense revenue has doubled since last two months from the same old sites. Another thing I noticed that image ads are generating more revenue than the text ads.
My blogs traffic decrease a little due to not updating my content, but suddenly my earnings increase. Ad placements may be one of the huge factor that really affect the change.
Ie we do the add's optimisation then we can earn alot.. even. .10 visitors... 3clixs... 2$....this is my way...

I manages 70 different pictures gallery while the traffic is usually came from google images, 1000 impres get 1 click, its bad, so don't follow my way
