When I signed up for Adsense, I created 3 sites, 1 that I focus on updating and optimizing, and 2 that I ignore just to get a little bit of extra money. I was parousing my stats today, and I saw that one of the sites I ignore that I just invited a lot of friends to, that gets about 10 hits per day, has a significantly higher click thru percentage even though I stuck with the Blogger Adsense widgets and didn't focus the topic at all (It is a free for all for whatever the writers want to write.) Since it only has about 600 total hits through 2 months, I'm not sure it's a good sample size, but still, it was an interesting discovery. Any thoughts on why?
No, they aren't really my friends, just other bloggers, and my CTR isn't high enough to get banned. They were recruited from other blogs, so I'm sure they know about Adsense.
your ctr is not relevant to getting banned. a 1% ctr that is 100% fraudlent clicks would get the boot.
