The easiest way to do keyword research is to explore Pinterest itself. Use descriptive terms that are aimed at your audience and industry and conduct a search on Pinterest. Once you start typing, you’ll notice that the site auto-suggests terms to help you narrow your search. Jot a few of the words down and include them in your pin descriptions, board titles, image text and profile.
Before you even start pinning, you can tweak your profile and pick the right username. You can change it through your settings and use one that reflects your presence and the way you want to be discovered. The URL will serve as your keyword, so make sure you pick a clear, direct and memorable username.
