2) 500 characters are allowed in the description. Be extremely specific when explaining exactly what the picture represents, and how it relates to your business. I use this area to ask the viewer a question to try and engage them. Make sure you insert keywords or keyword phrases in the description to make your pin searchable for both Pinterest and Google. This will also help your Google ranking.
3) Insert a call to action. Tell the reader what you would like them to do, as in the following examples:
click your link, subscribe to your newsletter, download a file, sign up for more information, leave a comment, watch a video, etc.
4) Add #Hashtags to your post. You can place them in the content, but I prefer to place them after the call to action. This is another way your pin can be searched for on Pinterest, so it maximizes the amount of viewers who may see your pin.
The example below is a motivational quote I recently posted. I used it to relate to the online business offer on my website. I asked the viewer a question, gave them a call to action (visit my website), inserted my website link, then gave them two more calls to action on what to do once they are at my website. Finally I inserted my hashtags keywords.
