The best way to increase the number of social signals that your pins generate is to optimize each one. Since a big part of this is to maximize their visibility within Pinterest’s search feature, a good starting point for optimizing your pins is giving them rich filenames. If you’re uploading a picture you took with your camera, change the filename to something descriptive instead of leaving the random letter and number combination that most cameras use. And if you’re pinning from another website, take a second to fill out the alt attribute with a descriptive phrase.
The next tip for optimizing pins is to link every single one to a URL. Even if you upload your own pictures from your computer, all you have to do is click edit and then you’ll be able to add a linked URL. The reason this step is important is because it will increase the amount of traffic that your pins are able to drive to the site or page of your choice.
Another thing to keep in mind is even though Pinterest descriptions can be significantly longer than tweets, brevity is usually still a good thing. So instead of feeling the need to use almost all of the 500 characters that Pinterest makes available, you should be able to write a catchy description in the 200 character range.
Speaking of Twitter, Pinterest also supports the use of hashtags. So even though they’re not something you want to overuse, don’t be afraid to add relevant keyword hashtags to your pins. Finally, as you’re getting in the swing of writing really good descriptions, one thing to remember is that you can include a clickable link within them. While image links are good, multiple studies have found that description links actually have a higher click-through rate.
