Here are a few ways to use Pinterest to boost your search ranking.
1. Link Pinterest to Facebook.
Pinterest allows you to link your activity to Facebook so all your pins and repins on Pinterest will appear on your Facebook wall, as well as the Facebook ticker.
You can also promote your pins on Twitter and Flickr. These are good opportunities to showcase your pins on other social networks.
2. Take advantage of link-building opportunities.
As Pinterest’s domain authority grows, your pins will have higher visibility in search engine results. (The more popular a domain name, the more likely it will appear in search results.) The more links you build to point people back to your site from Pinterest, the better your search results will be.
3. Enhance your keyword strategy.
Google now indexes personal Pinterest profiles and private Pinterest boards. Adding keywords to your boards increases the odds of them appearing in a search.
4. Add “pin it” buttons to your blog.
