I would suggest working on your tags. Most of yours are single word tags like 'earring' and 'set'. If someone searches 'earring set' in Etsy search, shops with a tag 'earring set' will be more relevant than any with two separate tags 'earring' and 'set' (like you have).
Basics:
--use multi-word tags over single-word tags whenever possible
--whatever category your item is in, those are automatically tags for you (consider them free tags). For example some of your items are in category: Vintage --> Jewelry --> Brooch. You dont need to add tags 'vintage' 'jewelry' and 'brooch' again. That is a waste of 3 tags.
--repeat multi-word tag phrases in your titles
Read some of the info in discussions in the Etsy Team called "Etsy Relevancy SEO and Stats" or look at the article called 'tags titles and descriptions' in the Etsy Seller Handbook Archive.
Best of luck!
