Wedunit Jewels: Beautiful jewelry in your shop! I think what might have happened before is that you were making sales based primarily on photos and luck in getting seen in searches. Now that there's more competition, possibly you need to up your game as far as SEO goes, and also with the copy. Couple things:
First thing to do is decide what your main objective is. The very first thing a buyer sees is an invitation to go to your outside website. If that is your goal, then fine. But if not, you've just lost a customer in your Etsy shop! If you want people to purchase here, then focus on Etsy and put any links to your outside website toward the end of your pages.
Also, there's more space that you can use in many pages to emphasize some of the special qualities of your jewelry. Right now there are only descriptions. You have lots of competition, so try to figure out what's so special about your items, what the top selling points are, what value your jewelry adds, and so forth.
Related to this is the About page. Currently you start off: "At Wedunit Jewels (pronouced We-dunit), my main focus is customer service." Is that really true? Not quality, beauty, style, quality of life, enhancing a person's lifestyle, or other messages along those lines? Think more carefully about what it is you would like to tell buyers. What will engage them and make them want to know more?
Also get going on the SEO. Ask for Mary's tips or even consider her professional services.
Hope all of this helps! Best of luck to you and your lovely shop!
