As further evidence of Reddit's red-hot growth, the news aggregation site had 100,000 unique visitors at one time on Monday, breaking a previous record.

The figure, provided by Google Analytics at 1:43 p.m. ET on Monday, didn't come from a particular post. The site had been nearing the 100,000 figure for a few weeks and finally hit it, according to Erik Martin, general manager at Reddit. The milestone comes after Reddit raked in more than 2 billion pageviews in December, double the amount the year before. Reddit also got around 35 million unique visitors that month, meaning the average users viewed around 13 pages per visit. Reddit broke the 1 billion pageview barrier last February.



Alexa currently ranks Reddit as the number 50 website in the U.S., with a daily reach ranging between around 600,000 and 1 million unique visitors. Digg, which has historically led Reddit in traffic, is still ranked higher on Alexa at 48 in the U.S., but has a reach of between 400,000 and 500,000 unique visitors.



Digg, which lost a lot of traffic after fans rejected its Version 4 introduction in August 2010, had less than half of Reddit's uniques in December — 14.1 million, according to a Digg rep.



Martin says the site's growth has been steady over the past couple of years — it zoomed past Digg in April 2011. He adds that there hasn't been a dramatic bump in traffic since the site he site took a stand against SOPA. Reddit's blackout on Jan. 18, made the site national news, but Martin says there's been "no bump, much less anything dramatic."



Reddit's growth is especially remarkable given the site's lack of reliance on SEO, Facebook and Twitter. In a blog post celebrating its 2 billion pageviews, the site claimed it “doesn’t know anything” about SEO and doesn’t link to its Facebook and Twitter accounts.
