When a user clicks on the button : I'm feeling lucky
, the first search result will be opened in your browser, bypassing the search engine results page. The concept behind is that, if a user is "feeling lucky", the search engine will return the perfect match the first time without having to look around through the search results.
Reports denote that this feature costs Google about $110 million each year as 1% of all searches made using this feature bypass all advertising.
