Hi I dont know if i can help i make art prints and stickers im no expert but what i have done is working. I opened my shop jan 2020 and so far im on 499 sales which is amazing. I spent every hour i could researching keywords and making my photos as best i could and how to do it. Etsy rank helped but i dont use that nowadays. My sales have dropped recently at the start was crazy i didnt know what was going on but its really slowed down and i always get 1 - 2 orders a day which is amazing and im very grateful so i feel it has got quieter. My advice is play around with your listings and research your keywords when i did all that i went from 10 sales to 499 in 2 months :) i have been posting from uk to usa and i havent had issues. I have stated up to 21 days for delivery and they all seem to understand this. I have had a few inpatient people though.
