Ive seen VERY successful shops that have NOTHING there. Just their name and where they live. I dont read anyones story when I am shopping. Its not really going to change my decision from buying (unless they said their items come from a drug infested home- it doesnt matter to me, personally) so im not sure if they get read alot.
I have some things but it doesnt talk about my husband, kids, dog, and extra activities like some people write. Whatever feels right to you, youll know.
From my experience, having my own photo as my avatar (on my profile) instead of an item or shop avatar, slowed down sales. I tested it many times and everytime I took down the personal photo (I dont think im hideous or anything, HAHA), sales flooded back in where they were stagnant before. Maybe it was a weird coincidence, multiple times, lol but whatever works best for you :).
