Break down the key words and be sure you are using keywords that really describe what you are selling.
Example: The "Steampunk" earrings are not. They are Celtic Knots. The Celtic lovers would never find those earrings and the Steampunk people will be disappinted when they click on the listing and there aren't cogs, gears, or other steamy goodness to be had. I know it's natural to want to get on the boat for whatever the hot new trend is to pull in buyers, but you have to have truth in advertizing.
Another example:
http://www.etsy.com/listing/74875490/big-butterfly-earrings-goldButterflies are ox brass or bronze but not "gold". IMHO
Break down keywords into their simplest form=: Example:
Instead of Gothic Evil Eye-do
Gothic
Evil
Eye
Instead of Deep Blue Sapphire-do
Blue
Sapphire
Instead of Gypsy Bohemian Renaissance-do
Boho
Bohemian
Gypsy
Renaissance
