Hi there! I've found it's best to search for group boards that work well with the topic you write (like healthy receipes or grocery shopping tips). Once I find one I like, I will review the board to see what they require to join -- some are closed, so you need to read. When I know a board is taking new pinners, I'll follow the creator and send them a request either via the Chat or Email (Depending on their preference). Sometimes you won't hear back, but most of the time they're happy to add you!
This is the best way that I've found group boards: look through the boards of some people you're following. Personally, I like to look at profiles of those who are larger authority figures in my niche (as those boards tend to be more active and high ranking), but it can really be anyone. 🙂
Thank you @authorbrookevs! Great tips! This is something I have not done as much as I need to as I was focusing on using Tailwind Tribes to grow but will not be branching out to group boards more as well. 🙂
Have you noticed if a lot of the group boards also have rules such as for every 1 pin you add you need to pin 1 or anything similar?
I have also heard that you can request to join a closed group also and that sometimes they let you join. I say it's worth the try if it is a good fit for you.
