I love your shop! You have a nice profile section and your policies are clear and understandable in laymen's terms (so thanks!)
You could try reworking your titles a bit. Take your lowest performer and work the title. I grabbed this cute spider to give you an example
Spider SVG, Girl halloween, Halloween svg, Fall svg, Halloween cut file, DXF, eps, DXF, spider clipart, cricut, silhouette
I would do:
Halloween Girl Spider SVG, Halloween Spider cut file, spider cut file, spider clip art', DXF, EPs, cut files for cricut, cut files for silhouette
Just be aware that the "new" etsy rules tell you to make a readable title but left it open to interpretation. They also said you could use punctuation or symbols to separate phrases. My titles look similar to this and I'm experiencing my best months ever. If you're worried about breaking etsys rules, change one or two poor performers and see if it makes a difference. Good luck!
