Launched a little more than two years ago, the social photo-sharing service has doubled its number of daily unique visitors to 4 million since January, according to new data from social media marketer Tamba. The site’s core users are women, age 25 to 54, but the site is attracting the interest of men, who now make up 28 percent of new members compared with 20 percent in January.
More money is also being associated with the site, according to Tamba. The percentage of social media-driven revenue that comes from Pinterest has grown from 1 percent in the second quarter of 2011 to 17 percent in the second quarter of 2012. In that same time, Facebook has declined from 89 percent to 82 percent, and Twitter has plummeted to 1 percent from 10 percent.
