With hashtags on Pinterest, now it’s easier than ever for people to find the freshest Pins for the businesses and topics they’re into.
Starting today, when you include hashtags in the description for a new Pin, Pinners can visit a feed of all the Pins that share that hashtag. Whether those Pins are promoted or not, the freshest Pins will always appear right up top.
How to hashtag
Hashtags on Pinterest work pretty much just like they do everywhere else. The key is to select the right hashtag for your Pin.
