I just looked at the tags of one of your aprons (so cute BTW) and you have too many tags that are just colors. You can use one or two to specify the main color but not every single one of them. I think you're wasting your tags. Try to use phrases instead of just one word (especially if that one word is just a color).
I'm not sure what tags I would use. I know if I was searching for them, I would type "girls apron" and go from there, but that's just one tag and you should use all of them. Maybe try synonyms for "girl" like toddler or infant. Maybe something like girl cooking apron or craft apron or school apron. I don't know.. I'm just thinking of the situations where a girl would use an apron.
I hope I helped a little.
Good luck!
