One of the easiest and most important things any website can do to help people to discover their stuff on Pinterest is to install the Pin It button. The Pin It button makes it super simple for people to save and share things they find on your site.
These Pins link back to your website and increase the spread of your content across Pinterest.
The Pin It button is easy to integrate. You just copy and paste a few lines of HTML and JavaScript into your pages, and you're ready to go.

Find  </body>, that is on the bottom of some blogs, ussually custom blog templates and imidiatly above that, post this code:

<script data-pin-hover='true' src='//assets.pinterest.com/js/pinit.js' type='text/javascript'/>

That's all and I hope you'r satisfied because it's simple but great. Thank you for reading and please share if you like it.
