Just read that Google is estimated to lose approximately $110 million of
revenue each year due to searches done through the “I’m Feeling Lucky” button and bypassing all the ads. In other words, around 1 percent of visitors expect Google to place the actual best result on top of others and are willing to go there directly without any browsing. Despite being a huge fan of Google, I personally never use that button and prefer to go through the results myself.

You may ask why the button is still there? Because, after all, Google was born from a couple of grad students sharing a dream and doesn’t want to look too much like the corporate (and sometimes scary) giant it has become.
