We all know Pinterest is hugely popular with people who want to save photos of lava lamps (or standup desks), but like other business concept trackers, we’ve been waiting to see how Pinterest plans to make money from all this user love.

How else? Advertising.

Today, Pinterest announced an expansion of its recently launched “paid pin” plan. While the early users are major brands, today’s announcement of a “Do it Yourself Promoted Pins” platform is following the business-model path created by Twitter and Facebook. (The 80 billion lb. gorilla in the “how to make money on the web” has a different approach to selling ads.)

Today’s announcement covered two new Pinteresting developments:

Do-it-yourself Promoted Pins

A do-it-yourself promoted pins tool “so businesses of any size … (can) get visits back to their website.” Users of paid pins can manage them at ads.pinterest.com.

New and Improved Analytics

According to Pinterest, you’ll be able to see which of your pins and boards are driving the most impressions, clicks and repins. (Sidenote: We’ve learned over the years to fear advertising metrics lists that leave out the word “revenues.”) You can see the new analytics page at analytics.pinterest.com. According to the announcement, Pinterest is rolling it out slowly to make sure everything works, but all business accounts should get access soon.

Please note: As with other social media platforms, advertising is not the only way to use them for marketing purposes. We’ve even mentioned a few small business marketing with Pinterest ideas ourselves, before.
