- in the 13 tags section (and my tags are in perfect conformance with 20 digits limitation that Etsy has)
- in the title of your listing (that has a 150 or more characters, so a few can go there)
- in the description itself
you can use some in Styles, Materials, Who is it For, etc - wherever appliable.
What I can do: I look at 5-7 successful shops in your niche, someone who is already established and has done research and come to some conclusions, look at ALL their listings, take all the tags and analyze them.
I also SORT them from most to least popular. And you really have a lot of choice for your own products!
What I need: up to 7 names of shops in your niche (preferrably), or just keywords to choose shops myself. I prefer that you find your competition yourself as it will be more efficient for you, you know it better than me.
