Today when I was talking with my cousin brother, he was just telling about the "Miserable failure" problem which was intended to George W. Bush in September 2006. It was really a funny story to how to change the Google page ranking. Google page ranking is an important criteria to optimize the google search results in the google search engines. So some peoples was trying to change the google page ranking through "Google Bomb" method. Actually "Google bomb" is mainly refer to practices intended to influence the ranking of particular pages, in results returned by the the search engines like Google. A Google bomb it can simply says as a "link bomb" is 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 (Miserable failure), but Google changed the ranking by January 2007 to instead list pages about the repeated linking of that text. Google bomb is used both as a verb and a noun.

It is intended to the search Engines through 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.

Further, the Google bombs were introduced to the history through the problem where a search for "more evil than Satan himself" resulted in the Microsoft homepage as the top result in 1999. And there after many Google Bombs have been encountered. But the most popular one is "Miserable failure" problem. When peoples entered the words "miserable failure" or "failure" into the Google search engine by September 2006, were directed to the biography of the president on the White House website - 'Miserable failure' links to Bush. Other search engines use similar techniques to rank results, so Yahoo, AltaVista, and HotBot are also affected by Google bombs. George Bush was ranked first for the keyword 'miserable', 'failure' and 'miserable failure' in both Google and Yahoo!, Google has since addressed this and disarmed the George Bush Google bomb and many others. Normally Google do not condone the practice of google bombing, or any other action that seeks to affect the integrity of their search results, but they're also reluctant to alter their results by hand in order to prevent such items from showing up. By January 2007, Google changed their indexing structure so that Google bombs such as "Miserable failure" would "typically return commentary, discussions, and articles" about the tactic itself.
