Here's some advice that I was given that I will pass along:
*DON'T list your items all at once. Someone once told me you are getting promotion every time you list a new item right? (blast on facebook, twitter, posting in promotion teams, etc.) So if you add them all at once, you are essentially getting the promotion of one product at the cost of 20 - it makes more sense to slowly release those items individually rather than list them at the same time.
In fact, if you just post-and-run on facebook (I'm guilty of this) then you aren't taking advantage of the tools you already have. I have seen the sellers with the most success on Social Media sites is to engage their customers, not just post their new items, but also before you post, put out teasers announcing a new product is coming soon. You can also just post musings or thoughts, what you are working on at the moment, etc.. Turning your business page into a more personal one is the best chance at getting your customers to get excited about your products. Getting a customer base is important if you want to stay in business for the long term.
*If you changed something and you are getting less views, you need to figure out what that was and change it back. It could have been a small tweak in SEO that turned out to be a bad choice, none of us really know what you did to change so you will have to figure out that one.
*PHOTOS, PHOTOS, PHOTOS. I don't know how to say this so prepare for the non-sugar-coated version: Your photos need serious work. I mean SERIOUS "learn what makes great photography on Etsy" - work.
I have seen nothing in your shop that shows "Front Page worthy" photos and that should be your goal in the next few months. You don't want just okay photos, you want GREAT photos - - this is a challenge we all face and ultimately, the success of your photos will depend largely on your current skills and how much you are willing to learn about how to take great product photos.
Study the front page. People always complain that the FP is never diverse, but really those people aren't paying enough attention. I see diversity on the FP every day, but no matter what, the 'theme' is always the same: great photos, well lit items that aren't washed out (and of course, there's the 'whimsical photos' but that's a whole other topic, lol), great close up shots.
All in all, jewelry is the toughest category to get into. Not only do you have to have an awesome product that is desirable (and not something they can find at 1000+ other stores) but you also have to present it in a category with people who hire professionals to photo their products.
In order to compete, it's going to take some serious skill, and not everyone has that skill. Good luck!
