Use it to follow people who will then likely follow you back.as your pins grow in popularity people are much more likely to follow through to your site and then maybe click on Adsense or CPA offers whatever is relevant to your niche

There is the possibility to post pictures associated with your brand usage and try to win more supporters to follow your feed. There isn't much of Pinterest you can use to help your site, in terms of SEO. It's made for pure sharing usability and nothing more.

Accurately describe the photo or video. Make sure the pin links to something relevant and informative. Run a pin it to win it contest. When people follow you, repin something of theirs.
