Web spam or search engine spam denotes the manipulation of web pages with the intention of improving their position in search engine results. Spammers use many techniques such as content spam, link spam or a combination of both. Detecting spam in search engine results has been a challenging task for search engines. This paper presents a review of three different approaches for detecting web spam. The first approach deals with language modeling that involves building a language model from different sources of information extracted from web pages. The second approach deals with checking the reliability of links, that is, the ability of a search engine to find, using information provided by the page for a given link, the page that the link actually points at. The third approach deals with the topology of a web graph by exploiting the link dependencies among the Web pages.
