I'm looking at your tags, and they really need a lot of work. Definitely studying up on SEO and Etsy relevancy will do absolute marvels for your views, and I'm confident that if you get plenty of views, you will get plenty of sales.
1. Use keyword phrases in the title (things buyers will search for). Avoid single words as much as possible. You might go for tags such as: halloween jewelry, pumpkin pin, halloween pin, halloween jewellery, halloween brooch, pumpkin brooch, wearable art, handmade brooch, handmade pin, kids jewelry, etc. I, personally, wouldn't waste tags with team names unless you've thought hard and can't think of anything else to fill all 13 spaces.
2. Repeat the keyword phrases as many times as you reasonably can in the description.
3. Repeat the keyword phrases in the tags. Sometimes it's a good idea to write the tags first.
4. Try to alternate which keyword phrases you use between your similar items, so whatever a buyer searches for, one of your items will come up.
5. Pack your shop announcement with keywords.
6. Your SEO and Etsy relevancy may also be affected by your shop categories, so use more specific categories (such as Owl Jewelry, Pumpkin Jewelry, Monster Jewelry).
7. Make your shop title (the little thing under your shop name, in the left column) something like "Handmade Halloween Jewelry." This will help SEO. For instance, mine is "Vintage Kitchen Utensils, Small Appliances."
Anything you can do to be found in searches will be time very, very well-spent.
