This year has been, without a doubt, the year of the Pin, and that reign shows no sign of stopping. Today, Compete revealed that Pinterest has surpassed Tumblr in terms of unique visitors.

For context, Tumblr launched in February 2007, and Pinterest hit computer screens in March 2010. In only a little over two years, the latter has overtook Twitter twice as a source of referral traffic, and even became the third most popular social network, directly behind Twitter and Facebook.

Each service is a valuable resource for digital marketers, who often rely on visuals to engage with fans. Both pull in a tremendous amount of traffic, but unlike Tumblr, Pinterest has a lot of “sticky” content — which encourages visitors to stay on-site longer and continuously come back for more.

According to Compete, the “appeal towards either site” is very different. Pinterest’s demographic seems to match the domestic Internet average while Tumblr tends to attract a younger audience. This is key for businesses using either platform to reach specific audiences. Depending on your target, you’ll want to focus more effort and energy on building a presence on one more than the other.

Still convinced that Pinterest is a passing fad? Only time will tell, but it appears to be going strong. We recommend taking a look at how other businesses are using the service, or now that it’s open to everyone, give pinning a whirl.
