Parasite hosting

Parasite hosting, in computing, is the process of hosting a website on someone else's server without their consent, generally for the purpose of search engine benefit.

Mechanism[edit]

Search engines such as Google rank search results based on the relevance to the search query and, importantly, an importance rating, such as PageRank, which is based in part on a link analysis of the web. Therefore, one strategy for increasing the search engine traffic to a website is to place a link or redirect on a highly-valued domain on which one can host a webpage. Educational institutes (including .edu domains), as well as some social news sites (for instance, Digg and Reddit), often allow users to create webpages, thus creating an opportunity to parasite host a webpage whose sole purpose is to increase traffic to a given target, without regard for the hosting domain's policies or intended use of the exploited space.
