Google Bombing

A Google bomb (also referred to as a 'link bomb') is Internet slang for a certain kind of attempt to influence the ranking of a given page in results returned by the Google search engine, often with humorous or political intentions।[1] Because of the way that Google's algorithm works, a page will be ranked higher if the sites that link to that page use consistent anchor text. A Google bomb is created if a large number of sites link to the page in this manner. Google bomb is used both as a verb and a noun. The phrase "Google bombing" was introduced to the New Oxford American Dictionary in May 2005.[2] Google bombing is closely related to spamdexing, the practice of deliberately modifying HTML pages to increase the chance of their 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)
Some website operators have adapted Google bombing techniques to do spamdexing। This includes, among other techniques, posting of links to a site in an Internet forum along with phrases the promoter hopes to associate with the site (see Spam in blogs)। Unlike conventional message board spam, the object is not to attract readers to the site directly, but to increase the site's ranking under those search terms। Promoters using this technique frequently target forums with low reader traffic, in hopes that it will fly under the moderators' radar. Wikis in particular are often the target of this kind of page rank vandalism, as all of the pages are freely editable.

Another technique is for the owner of an Internet domain name to set up the domain's DNS entry so that all subdomains are directed to the same server। The operator then sets up the server so that page requests generate a page full of desired Google search terms, each linking to a subdomain of the same site, with the same title as the subdomain in the requested URL. Frequently the subdomain matches the linked phrase, with spaces replaced by underscores or hyphens. Since Google treats subdomains as distinct sites, the effect of a large number of subdomains linking to each other is a boost to the PageRank of those subdomains and of any other site they link to.

On 2 February 2007, many have noticed changes in the Google algorithm that largely affects, among other things, Google bombs: only roughly 10% of the Google bombs worked as of 15 February 2007। This is largely due to Google refactoring its valuation of PageRank.
