I'm by no means an expert...but in the listing I looked at you had several tags twice. The first 3 are Etsy generated by your categories, no need to add them again. And I would use more than one word, for example instead of just 'gentle' I would use ' gentle soap' or 'glycerin soap' or 'natural soap'...you get the idea. Use short phrases.
Lovely shop, btw! I'm going back to look some more :)
