Scraptrapped:
I would have searched on cell phone cover, not cozy or case. When I did that, none of your items came up. Also, in tags, I would put iphone, ipod, Droid, cover, case, cozy, crochet, knit (yes, it is a stretch, but some people don't know the difference between knit and crochet and are just looking for something made of yarn).
Another recommendation I've red is to put the keyword in the first line of your description also, ie "This cell phone cover case is crocheted...."
Also, for Google Searches, they don't like lots of items titled exactly the same. That is hard for you since most of yours ARE the same. Maybe do one as IPOD cover, the next as IPHONE cover, next as DROID case, next as CELL COZY, next as CELL PHONE CROCHET COVER.... get the idea? You can explain in the description, but that will at least get them to your shop in a search.
Nice items. Now I need one for my Droid!
