Hi Nicole,
Beautiful jewelry! Brand new seller here, so what I would say has more to do with things I have read in articles for new sellers, etc. and less from personal experience. Fair warning :)
The first thing I have read is that Etsy ranks you and places you higher in searches the more items you have. So, I would recommend adding more items to your shop if you have the ability to! Especially if you are active on social media, promoting new items I think is a great way to draw in customers old and new.
Also, when looking at your photos - the neclace and anklet photos draw a lot of my attention, while the earrings don't as much - I think it might be because they are not shown on a person. I'd highly recommend putting them on a model or yourself or at least holding them in your hand, to show scale and add a personal touch.
FInally, when tagging your items, I have read that it is better to do longer, more specific tags. For example, instead of tagging "silver" and "anklet" separately, a shopper would be more likely to actually type "silver anklet" together, so that should be your tag. The more specific the better, because you are more likely to show up in a specific search of someone looking for a "fresh water pearl choker necklace" than someone looking up "choker."
Hope that's helpful! Good luck!
