On the very first step it might seem little bit hard but it shouldn't discourage you, give some time for your Pinterest profile and I would recomment you
-Pin consistently at least 5x per day
-Write keyword-rich descriptions and boards. Use Pinterest like the search engine it is. Make sure your pin descriptions are on point. Use rich pins to add more information to each post.
-Design images at the proper size.
I hope it helps!
@PinterestGabby Terrific! Looking forward to that article, as I'm finding it hard to understand why Pinterest wouldn't want you to pin other peoples pins. I would've thought it would be just the opposite.
