Adsense Spam blogs as the name suggests, are those blogs that have very little or nothing in terms of content and are set up mainly to attract and drive traffic in a certain direction. The vast majority of these spam blogs carry Adsense ads because the purpose of the spammers is to generate lots of Adsense revenue in this illegal and unacceptable manner. Many Adsense spam blogs are set up for the sole purpose of creating hundreds of links pointing to a target blog so as to improve its’ SEO ranking with leading search engines. The spam blogs also contain links pointing to one another, designed to maximize their illegal traffic in the network of spam blogs.
This Adsense spam blog menace has mainly hit popular service providers who host free blogs. Blogger.com, the most popular and host to millions of blogs has been the worst hit.
