Claire, thanks so much for the Pin button! LOVE it :) New to Storenvy, been on Etsy for a while and looking to expand. Here's some things I do:
-Connect with bloggers like has been said, this is especially great for my FB numbers as I don't have a blog myself, only an FB page
-Hosting giveaways on my FB page with my own product
-I host product reviews as a thanks to other vendors when I win something from a giveaway. They usually promote for me as well.
-Advertise on blogs this is nice because smaller bloggers will do it for free/product exchange and be willing to talk you up quite a bit
-Participate in other page's giveaways if they are at least twice as big as me. This has helped a lot.
Hope some of this helps a little :)
