I get a really high clickthrough rate on that banner, even though it's only at the bottom of one page. But recently someone offered to review my website, and I accepted.. and they reviewed that Instant Grammar Checker site instead! That's right, they clicked the AdSense ad on the front page and reviewed that. Apparently people think it is part of my site because the ad fits in with my layout.
What do you think, warriors? Should I take the ad down so people actually look harder at my services without clicking to another site? Or should I enjoy the (small but consistent) amount of AdSense income it brings?
