Hey Evelien,
Sorry that you feel so invisible :(
I had a quick look at your shop and I'm sure others will help too. Not sure why someone told you you have no banner because you obviously do!
There were two things I noticed from looking at your shop for a minute or so.
First thing I would suggest is to brighten up your photos. They are a little dark and its a really easy thing to be able to do. There are a few free photo editors available on the internet you can use to adjust the brightness and contrast of your photographs.
The other thing was, the first thing I clicked was this:
http://www.etsy.com/listing/78105521/crochet-puff-from-recycled-materialI clicked it because I think it is lovely! But the listing says it is a powder pink but it looks like a blue grey. This would put me off buying because I would be confused so make sure all your listings are right, and if it is powder pink, make sure it looks the right colour :)
Hope this helps a little. I'm no expert though!
Oh and to get more visits, make sure you promote new listings in promotion teams and other teams where you can link your newest stuff, join twitter and tweet everything and join facebook. Maybe even blog. Trust me, you end up spending more time talking about your items than actually making them :D
Good Luck!
