Hi, Please take a look at my site. I just bought it. It's got ads all over it, but very few people click on them.Why. The site is practical ebay selling . com
Well, if it's less than 1% CTR, that means you're most likely already smart priced. Google smart prices accounts that don't perform well to save their advertisers money - so if you're smart priced, you won't make as much per click as you would otherwise. When you're smart priced, ALL sites using your Adsense code will be affected, so I'd recommend removing the Adsense blocks from all sites that have under 2% CTR for about a week, then add them back. But anyway, the ads have very good placement and blend nicely, so I'm not sure what the problem is.
