We offer a Pinterest for Business site to help brands and businesses who wish to use Pinterest to connect with their audience. There you'll find Pinterest tools and resources relevant to you, and see examples of how other businesses are using Pinterest.
As simple as it sounds, best practices for using Pinterest for business purposes center around Pinning like a regular user. Most importantly, this includes:
Pinning from various sources rather than one specific site.
Pinning from within Pinterest to engage with others – Pinning is one of the most social activities on Pinterest and it's how any user really builds his/her network of followers.
Creating at least a few boards that cover a broad range of interests, rather than maintaining a single board devoted to one topic.
Pacing your Pins so that your followers aren't overwhelmed by too many Pins in their feed at once.
For businesses, Pinning can be a great way to highlight aspects of your brand that may not come to mind at first when people consider your brand. Pinterest can also be a great tool to learn what your audience/users/customers want and like.
