Google Bomb | Googlewashing

The terms Google bomb and Googlewashing refer to practices intended to influence the ranking of particular pages in results returned by the Google search engine.

A Google bomb (or "link bomb") is Internet slang for a certain kind of attempt to raise the ranking of a given page in results from a Google search, often with humorous or political intentions. Before 2007, Google's search-rank algorithm could rank a page higher if enough other sites linked to that page using similar anchor text (linking text such as "miserable failure");but Google changed the ranking by January 2007 to instead list pages about the repeated linking of that text.
Google bombing is closely related to spamdexing, the practice of deliberately modifying HTML pages to increase the chance of their website being placed close to the beginning of search engine results, or to influence the category to which the page is assigned in a misleading or dishonest manner.

The term Googlewashing was coined in 2003 to describe the use of media manipulation to change the perception of a term, or push out competition from search engine results pages (SERPs).
