Typo squatting is a method of registering a misspelled variant of a popular web domain and Google may be earning a whopping $500 million a year via companies and people who register these deceptive website addresses.

 

Tyler Moore and Benjamin Edelman at Harvard University have estimated how much money this could bring to Google.

 

According to them, up to 68 million people a day could visit a typo site and up to 60 percent of typo sites could have advertisements supplied by Google. The team of two from Harvard say that the company can easily earn $497 million dollars a year in revenue from typo domains.

 

In the year 2009 , the revenues from advertising were about $23 billion.
