If you’ve been curious about what sites benefit the most from Pinterest, we now have some insight.  RJ Metrics has the inside scoop…and boy does it look yummy. I mean it. If you’ve checked out any of the food-related boards, they make you hungry. I digress…

Their recent research looked at a database of nearly one million pins to identify the top-level domains most often “pinned.”

The most popular domain was Etsy.com, which powered just over 3% of pins.  Close behind was google.com, although almost all Google links point to Google Image Search, which is technically misattributed content from other 3rd party domains.  Flickr (2.5%), Tumblr (1.1%), and weheartit.com (1.0%) round out the top 5, after which no domain represents more 1% of pins.

Here’s the actual breakdown:

FUN FACT: More than 80% of pins are re-pins.
