The most important thing to consider with Pinterest is how people use the site. It’s virtual window shopping, so anything you do on Pinterest needs to center around extremely strong visuals — the goal is to capture someone’s attention and draw them into your “storefront” (click through to your website).
Apartment companies can create their own Pinterest pages (business.pinterest.com), but they should also be thinking about how they can create their own “pin-worthy” visuals. What can you showcase on your website that looks so great that your visitors might want to pin it to one of their boards?
