Just had a quick look at your shop, and I love your banner, and you have some great items with good photos too.
~ I think you need more stock in your shop, as people tend to like to browse through at least a page or two of items. Apparently having plenty of items gives buyers the impression that you are 'serious' about your shop.
~Also, your shop sections don't mention gift tags any way - it might be an idea to have a section for that.
~ I've just picked on one listing for a closer look:
http://www.etsy.com/listing/110428806/hallloween-gift-tags-double-sided~The title looks good, but I would add the colours in there as well, or maybe 'Pumpkins' and 'Candy Corn', as those are both things people looking for Halloween items might use in their searches. Maybe you could also add a line or two about why someone needs the tags? So something like 'The perfect finishing touch for that spooooky Halloween gift!' It's very early here.;-) Also maybe mention the colours in the description, and perhaps in the tags?
~A very quick one for this wreath:
http://www.etsy.com/listing/111189668/18-halloween-wreath-spider-glamAgain, I would put 'Halloween Wreath' at the beginning of the title (important words should go first), then add the colours, and maybe 'Spider' as well? I don't know if people would search for an 18" wreath, but they would search for a 'Halloween Wreath' or 'Orange and Black Wreath'.
Feel free to ignore any or all of this advice, as I sell jewellery, not home decor.
