I don't claim to understand anything about bounce rates as I am one of the many Etsians who pay no attention to anything like that as it's too time consuming, though I do look at my Etsy stats now out of curiosity.
There may be a reason behind, I honestly don't know either way. Having had a very quick glance at your shop though I would highly recommend that you read and apply this
http://etsymentors.blogspot.com/p/critique-your-own-shop.html because I can see areas on first glance that need some work that have nothing much to do with SEO and will help you full stop. Your bounce rate might purely be down to a lack of items in your shop - you don't even have a full page of listings.
1) Use all 10 sections
2) Set your location to the correct format so you appear on local searches. To correct it go to Your Account - Public Profile - scrowl down to City, delete the current text, start typing in your home town/city, select the location suggested by Etsy and save it.
3) List more items - less than a page is not going to help you at all.
As for everything else I don't know without digging deeper. Do read and apply the above and when you have either ask here or on SASsy Critiques for further advice, we will be happy to help.
