But what's not mentioned nearly enough is how good this traffic could be for online retailers who are willing to do a bit of research, and able to give a small (10%) discount for a product for a limited time to drive traffic.
added some functionality (which was later to become Rich Pins) to a number of leading websites. This functionality enabled (for this purpose) "Product pins for things like clothes and furniture with pricing, availability, and where to buy (updated every day!)"
Then, in August 2013 Pinterest added notification emails of price drops on products that you had pinned.
Then in October 2013 Pinterest made Rich Pins available to everyone.
These Rich Pins make it possible for all e-tailers to add the meta tags and validation necessary to generate a richer pin experience that for e-commerce sites includes pricing, a buy link, and more.
So what generates a price notification?
recent pins from Pinch Good's e-commerce site. Notice clusters of one product being pinned over and over again? If you are an e-commerce site manager and see a large cluster, you might want to wait a few days, and then change the product price (via a sale perhaps? no coupon code!) the threshold amount and all of the people that have pinned that product will get a notification like the one shown at the beginning of this article.
How much does the price need to drop? That question had us searching... and what we found amazed us: "if we detect a price change of more than 10% on product pins, we'll automatically send out a notification to people with this Pin that lets them know the price has dropped."
Lower your price 10% on a product and all of the people that have pinned a product from your site will get notified of that price change.
In our opinion we believe this can be huge. How big?
And because this original pin was a Rich Pin, 5,000 people will be notified (from this one pin!) when you drop that price. Rather than discounting your product 20%, sending out a mailing to your subscribers (costs money), and promoting it on Facebook (also costs money), this -10% sale price will go out to people that perhaps haven't followed you or subscribed to you, and will also result in them getting an email direct to their inbox.
