Okay, I'm just picking one item at random to talk about here:
http://www.etsy.com/listing/114501777/beaded-bracelet-swarovski-crystalPictures: Okay, right off the bat, it looks like your main picture is a bit blurry to me. Try to clean up those pictures a little bit. Second, use all the photo spots. Show it from as many different angles as you can.
Titles: You're on the right track, but you need to keep in mind that the first 3 words of the title are the most important. If you're selling earrings, make sure 'earrings' is one of the first 3 words of the title. For this bracelet, you've done well there.
Descriptions: You're doing well on selling the item, but there are some grammar issues to clean up. Misspelled words, words that shouldn't be capitalized, etc. Things like that do matter to those shopping. Also, don't be afraid to put in back links! Add a link at the bottom of the description pointing people to the earrings that compliment the bracelet! It's a perfect way to boost traffic and sales.
Tags: Especially important for getting found in such a swamped section as Jewelry, you need to stay away from one word tags all together!! You're doing well on the number on this listing (you always want to use all 13!), but you need to make sure that you have the same keywords that make up your title in your tags. That's extremely important for SEO. Also, keep in mind that Google doesn't look at the tags, so make sure you work as many of the tags you come up with into your descriptions so that you can get traffic coming from Google and other search engines too!
And lastly, number of items in your shop: You only have 45 items right now. That's a very small number for such a saturated market. Work on raising that number to get more exposure. The more you have for sale, the more traffic you will get.
Hang in there, and keep at it! You'll get there!
