Computing Reviews released an interesting topic: “Adversarial
Information Retrieval: The Manipulation of Web Content:” by Dennis Fetterly of Microsoft Research. To summarize, Fetterly demonstrates: how search engine results can be manipulated by content providers. By using methods such as adding unrelated content to meta tags, duplicating information, and cloaking content so it is indexed
differently, Web pages can improve their result rankings. While the economic incentive for achieving high rankings is significant, manipulated results undermine the trust of millions of users. Fetterly suggests research into link-based spam detection and the identification of spam blogs, and advocates the development of a clear set of rules
for search engines. This is a worthwhile read.
