Social media data analyst Dan Zarrella has tracked what kind of content gets "repinned" most often on Pinterest.

The lessons: Items about food (particularly recipes) and tall vertical photos seem to get the most sharing traction. So the photo embedded here, for example, seems almost irresistible to a Pinterest user. Images about design and style are the most commonly pinned overall.

The most pinned words are: love, home, things, style, ideas.
