Pinterest is a good place to get your products or offerings in front of people if you are in a creative field such as photography or architecture, or create unique one-of-a-kind products. According to socialtimes.com,
Among e-commerce sites, Etsy gets most traffic, with more than twice what Amazon gets despite having a far more limited selection of products. (Etsy’s total share of outbound traffic is 1 percent.) Etsy’s niche audience syncs nicely with Pinterest’s crafty and female-leaning user base. Etsy was also the first e-commerce site to include “Pin It” widgets on every item listing.
MarthaStewart.com gets only a tiny fraction less traffic than Amazon. Walmart didn’t get enough traffic to rank.
This should tell you that creative people will have an edge in getting Pinterest users to click on their links to their own websites.
