Here's a bit about SEO that I've learned lately.
Titles:
Word 1: what is the item (bracelet, ring, necklace, etc)
Next phrase: other words describing the item (colours, other adjectives)
Last phrase: "by [your shop name]"
Tags:
-Use all of them!
-Some great tags: the colours of the item, the materials you used
-Think about what shoppers will type in the search box when they are browsing.
The first line of your shop announcement should be a description of what you create. Same with the phrase that is underneath your bold username on the top left of your shop. The phrase that is underneath your username is what will show up on the tab on the top of the internet window (for example, the title of this window is "Brutal honesty, only, please")
You also should put in shop policies. There are a lot of people who will see no policies, and walk out of the shop. Buyers need to know your policies on shipping, refunds, returns, customer service, etc.
Photos: Try to use all five photo slots. Since buyers can only see pictures of your items, and not hold them, they need to be able to see as much of your items as possible.
I would like to see a little more about you in your profile too. What makes you want to create? How did you start? People want to know more about you, and they look to your profile for that information.
Also try to add more inventory. I know that is very time consuming, but it's worth it in the end. The more items you have, the more chances that people have to click on your shop!
I hope these ideas help, and I hope I haven't babbled too much! :)
Good luck!
