Hi Elizabeth, I'm certainly no expert as I'm here for a critique myself, but I had a little look at some of your lovely yarns and think that you could perhaps improve a little on some of your keywords. I'm sure there are people a lot more in the know about this than me, but if I was searching for yarn I'd be typing in 'chunky yarn' or 'double knit yarn' or 'knitting yarn' or something a bit more descriptive of what I'm after. Good luck with your shop and I hope you get some helpful responses :)
Kate
