In fact, you should be spending a lot of time figuring out what the best way is to promote your content—I try to live by the 80/20 rule. I spend 80% of my time distributing my content, or figuring out the best way to promote it, and only 20% on the actual writing. Obviously, the quality of the writing is important, but it doesn’t matter how good it is if you aren’t spending the time to get it out there.
Most importantly though, remember that Pinterest is a community just like any other social media, so make sure you’re active, connecting with others in your niche and re-pinning others’ content too. If you’re just shouting into the void by only sharing your own images, you’re going to have a hard time gaining traction and figuring out how to drive traffic to your blog from the platform.
