I started mine a while ago as well and made a few posts and then stopped because I didn't have the time. But I've started up again and have learned some things to help build up my blog. Here are some tips:
-Post interesting content. Readers tend to like lists of thing. Top Ten Favorite Etsy Items, Top Ten Favorite Pinners... etc.
-Post about a fellow blogger. Feature them in an article, and then Tweet them to tell them you did. You will start to get a fan base (hopefully) from that bloggers followers.
-Post often. And better yet, post regularly, on the same days, so readers know when to look for new posts.
-I think the MOST valuable tool that a new blogger can use is social media. Use Twitter, Personal Facebook, Facebook Fan Page, Pinterest, Personal Website, EVERYTHING! Most social media sites make it EXTREMELY easy to share links to your blog. I always post to my Facebook Fan Page, Twitter and Pinterest whenever I have a new blog post.
-If you already have a customer base, you should try sending out a weekly or monthly newsletter. Full of tips and products, but most important,your social media links!
-Most importantly, don't overflow your viewers with product, special offerings, discounts..etc. Make your content worth reading. It doesnt always have to be about your shop. Post a variety of topics to gain readership from different kinds of people.
Hope some of these help!
Best of luck!
