I started my blog about 2 months ago when I opened my Etsy shop...
I see trough Google Analytics that most of my readers are returning visitors...but they are not always "followers"... Haven't got much followers so far...
I did put an Etsy Mini on my blog and saw that it did bring a bit of traffic to my Etsy shop.
I just suscribed to Hello Cotton, that can be helpful too...got some followers there...
Anyway, for now, I'd say I'm blogging because it keeps me motivated. I like to share with people, even if I don't know who they are! Also, since I've been on mat leave for almost a year now, I had a huge need for communication...and blogging made me feel good so...why not?!?! ;)
Here's mine:
