I agree & i didn't look at your listings,that's just general things to look at as a possible cause when sales are down.

I had a huge drop in views & sales for over a month.I keep record of everything & have not changed start price,kind of items etc.So i see a pattern change & know that something different is going on & many others are noticing it too.The only common factor is eBay.They can turn your listings on or off whenever they please & i think they are experimenting with it.

They don't even hide the fact that they fiddle with that as in the User Agreement somewhere that states something to the effect-'...accordingly to guide user satisfaction,an item may not appear in a search regardless of the search order" something very close to that wording.In other words if eBay think that a customer may not be happy with a sale from you if you have low DSR defects,they may protect them by hiding your listing.

My defects dropped from 1.73% to 1.32% (i think) & it was the 1st week of views & sales like i used to have say 2 months ago.

Not much can be done by the seller except keep up on the right keywords without spamming & hope that it is seen.
