Alot of people say their sales are down from the last 18 months or so, this is mainly due to Etsy Ads, they want you to pay for the SEO, don't see this as a bad thing, adapt and over come, like all new expenses the cost must be past down to the customer, that's just good business sense, this is how I made it work for me. First of list all of your products on Etsy Ads Remember to turn off those products that are not in season. Make your sure your budget is affordable for the next 3 months. Over the next 3 months you are collecting data, don't focus on profits. Once you have found out what is selling turn off Etsy ads for the product's that have not been selling and adjusted the amount to just the products that have been selling, Then work out on average how much you are spending on Etsy Ads for the products that are selling over a 3 month period, then apply that to the price. Unfortunately you have invest a little bit to swim again. Etsys business model changed, and must go with the tide not swim against.
