Image-based platform Pinterest can drive a lot of brand interest as users share upwards of 250 million photos a day, most of which include wedding dresses, sweets, makeup and more wedding dresses. Brands can also gain a lot of insights into their audience and which images are most engaging. But there’s a catch. Pinterest is a blackbox for marketers without a public API. As a result, an entire cottage industry has surfaced with companies like Pinfluencer and Triple Lift which crawl the site to collect some of this data. We anticipate brand tools coming to the site, but until then, you’re best bet is giving these guys a call.
