https://www.etsy.com/listing/127578358/crocheted-pixie-hat-crochet-baby-hat?ref=shop_home_active Sure! First, I would put "Crochet Baby Hat" as the first phrase in your title. It's more likely to be searched that "Crochet Pizie Hat". Just switch those 2.
Next, don't forget to use "Baby Bonnet" as a tag. Also "infant baby girl" doesn't really work, because no one will search that particular phrase. Split out "baby girl."
I noticed that you use the tags "knit" and "beanie." Those seem inaccurate for this listing. If I searched for a "knit beanie" and this came up, I wouldn't click it because it's not what I want.
