Views don't equal sales, that's been proven to me - I've had weeks where I've had hundreds a day, and never sold a thing, and when they dropped to like 20 a day, I sold a couple of things. It's about the right people seeing your stuff.
HOWEVER, my views have been atrocious for the past month and a half, eventhough I've added lots of new items this week, and while I remind myself that views don't equal sales, if people don't see your stuff then you can't sell it.
Unfortunately I can't offer much in the way of suggestions. Try tweaking titles and tags, and revisit photos if the need is there, maybe also renew some items and ask a blog or two if they'd be so kind as to do a feature on you, or interview you.
