Observations from the results of a 7 month old site which just reached 10m monthly interactions on Pinterest and just passed 200k visitors per month from Pinterest.
- The Pinterest account for that site was created on the same day it launched
- The site owner created outstanding large image pins with text
- The images were all watermarket across the bottom with the site url
- The site covers 3 of the most popular topics on Pinterest
Then it gets interesting
- None of the images are on the site, they were created solely to be added to the Pinterest account(not hidden etc)
- None of the text associated with the pins is on the site, title or otherwise, 100% manually done
- The site does have a pinit button but it's at the bottom of the page and not used
- The site had no visitors from search when it passed 100k monthly from Pinterest
If getting traffic from Pinterest is your goal then create awesome pins with enticing text and unique descriptions FOR PINTEREST, not on your site. In fact you can block Pinterest from working on your site and get fantastic results anyway.
The question isn't 'what can I do to my site to get traffic from Pinterest', it's 'What can I do ON PINTEREST to make THEIR users interested in checking out my site FROM PINTEREST'. The answer, awesome images with text and an appealng account layout. Pinterest is a search engine which lets you decide which searches to satisfy, but only if you get great stuff on the site, your site is irrelevant to Pinterest.
If your site is not for the 18-34 86% female crowd Pinterest is not for your topic. Collecting pins from around the web or re-sharing pins is optional. This and several other newer sites confirm that just putting amazing pins on Pinterest directly, even if the images aren't on your site, works well.
