How to Find Keywords in your Niche on Pinterest:
The trick I use to find keywords on Pinterest is really simple: The search bar! When you begin typing in things related to your niche, the most popular searches related to it will usually try to pre-populate first.
Write those down to keep track of them then make sure to use them in your board titles, pin titles, and pin descriptions. When used in any of those places they will pop up under that topic if anyone searches for it.
