Today I got a cent on AdSense for just 10 page impressions and no clicks. Ofcourse it was others visiting those pages.

This means that, they do pay per impression and not just per click. That motivates me to create more content.

I also decided to add google.com itself in my competitive filter ads, because now who doesn't know about Google. Everyone knows about Google, so having them take up the Ad space is a waste in my opinion.
