Infolinks is an in-text advertising program. In-text ads appear within the text instead of being displayed in ad blocks like Adsense. After activating the Infolinks advertising program on your blog, double underlined words randomly appear throughout your blog posts. When a visitor mouses over the double underlined Infolink, a bubble ad appears and you earn some money if the ad inside is clicked by the visitor.
I read some good reviews about Infolinks and decided to put the ads in my blog to see what would happen. I ran Infolinks ads for less than one month before removing them for a few reasons.
Decrease In Adsense Earnings
I noticed a drop in my daily Adsense earnings soon after activating Infolinks. I waited a couple days, but decreased Adsense earnings continued until I took down the ads. After removing Infolinks from my blog there was literally an instant increase in Adsense earnings within one hour of removing the ads.
