From Business Insider:

Microsoft’s upstart search engine now delivers results that are just as good or slightly better than Google’s, according to a post on Search Engine Land by a marketing manager for legal directory Avvo.

Conrad Saam conducted 20 searches on both Bing and Google, avoiding easy navigational searches like trying to find the right URL for a particular company. Instead he split searches between tough informational questions, like “attorney Tom Brady,” which Google mistook for a query about the famous NFL quarterback, and transactional searches like “Cheapest flights Seattle to Launceston”. Then, he subjectively rated the accuracy and authority of the results.

Bing won.

Proof being the best doesn’t mean you get branded as being the best.
