https://www.etsy.com/listing/160680178/18-inch-handmade-rag-doll-stars-on-dress?ref=teams_postBy having the tags 'rag doll', 'cloth doll' and 'cloth rag doll' you're really repeating yourself and it's not going to help you. Eliminate the cloth doll and rag doll tags. You've got that covered in the cloth rag doll tag.
You have the tag 18 inch. 18 inch what? Ruler? work of art? you need to specify that this is an 18 inch doll
What does children and toddler mean? If you're doing what I think you're doing, you're trying to attract people looking for general children or toddler items and it's too general a tag. Try specifying childrens doll (the apostrophe won't show up) or toddler doll
soft toy isn't bad but I'd also add the word doll to it
I would avoid using the word homemade -- it has a connotation of not being made well, true or not. Say handmade cloth doll instead
handmade rag doll
straight curly what? if you mean hair, your description and title say straight hair. If you imply the doll has curly hair when it has straight someone looking for a curly haired doll won't be pleased. Say straight hair doll
stars on dress -- what is this for? Save this for the description.
Is this at all customizable? If so, mention that
If you need other tags, try saying gift ideas, birthday gift, gift for toddler
Make sure you use the same tags in your title as you use in your tags and make sure your tags are sprinkled through out your description, especially in the first 140 characters.
