Hi all, I'm seeing a disturbing trend with my adsense earnings. Lately (last 2 weeks or so) my MSN traffic has been growing but my adsense earnings per click are dropping... now it's less than half of what it used to be. My CTR is about the same, nothing else changed on my site as far as layout or optimization. It's a blog but the new posts have always followed the same theme and style so I don't think it's because of that. When my site was 90% Google traffic, I was making a killing. Now with 15% of my traffic coming from MSN, I'm making even less than before! Could this be the problem? If so, should I redirect MSN visitors to another site?
