Hi Katrina,
Cute shop!
https://www.etsy.com/listing/186685759/day-of-the-dead-earrings-halloween?ref=shop_home_active_9Ehhh, I don't see anything wrong with your titles. I looked up a couple keywords and you were on the first page. These were specific to items in your shop, like candy skull earrings. Besides being on the first page, your listing really stood out.
I've learned titles to start with a simple few words on what it actually is.
Candy Skull Earrings for example. Then, I've seen people posting their success with adding more groups of keywords after. Ex ....Stud Earrings. Clay Earrings. for x, y, z holiday.
Just have time for the first shop. I know it's not much information. Just wanted pass along what I know and say your shop is awesome!
Much success!
