According to Compete, the popular social networking site "surged past" Yahoo in January by drawing nearly 134 million unique visitors in a single month.
"It's been two full years since we've seen a shakeup at the top. In February, 2008, Google overtook Yahoo as number one, and never looked back," wrote Compete's Aaron Prebluda.
"Is Facebook's next conquest the Google traffic throne? While eyeballs are newsworthy, the real story is engagement, especially in the ongoing battle for those coveted big brand dollars. On this front, Facebook is second to none."
Prebluda added that 11.6% of all time spent online was spent on Facebook, compared to 4.25% for Yahoo and 4.1% for Google.
However, Prebluda speculated that Google's recently announced Buzz feature could eventually affect Facebook's ability to "keep up” its current pace.
