San Francisco – Google (NASD: GOOG) may be
earning $497 million each year from the ads that run on sites whose URLs are
similar to a popular site but mistyped by users, ZDNet.com reported, citing a
study from Harvard
Ben Edelman and Tyler Moore. The researchers looked at 285,000 of 900,000
misspelled website URLs, and estimated that the top sites are collectively
receiving at least 68.2 million daily visitors.
