Facebook was outdone by the Mountain View based tech giant Google in the race to nail the top spot in this year's No. 1 Web brand, according to Nielsen's annual report.
Google, according to the report, secured the top spot with around 153.4 million unique visitors on average per month. Facebook, on the other hand, stood at No. 2 spot - all thanks to the 137.6 million unique social media enthusiasts who visit the site every month.
Facebook was closely followed by the online portal Yahoo! with 130.1 million unique visitors every month. The fourth and sixth spots were captured by MSN/WindowsLive/Bing, and Microsoft itself respectively, leaving the fifth spot open for Google's online video sharing portal YouTube.
YouTube, on average attracted around 106.6 million unique visitors every month throughout the year.
When it came to the social media and blogs, no other platform could even come remotely closer to Facebook. In comparison to Facebook's 137.6 million unique visitors every month, the second spot holder Blogger could attract just 45,712 monthly unique visitors.
"Smartphones were popular in 2011, making up the majority of new phone purchases with Apple as the top smartphone manufacturer and Android as the leading OS," the report added.
