I opened my shop on March 30th and so far have had 24 sales. I started by joining a few teams and really networking.
I also used the ETSYONSALE application to run a grand opening sale to draw business in. I only held the sale for one week, but it did bring in sales for me which I hope will be repeat customers. I didn't know that if you use a referral code you get 10 free credits. If you want to try it, my code for referrals is below.

The other advice I got that was really helpful is that the titles of your products have to be exactly what you would type to find the item. As much as you may want to make up a cute title to set your item apart from the rest, it won't show up in searches that way.
Also, pictures are so important. Try to use all five spots and make sure they are high white around the edges. This gives you the opportunity to show up in treasuries and makes your photos more appealing to the buyer.
Lastly, use all 13 of the SEO tags. Use phrases like "handmade knitted hat" rather than single words, as this helps your stuff show up better in searches, too.
Hope this is helpful!
Best to you all!
