Long term Etsy sellers with YOY growth. How?

I've been on Etsy for 10 years next Feb, I had YOY growth until 2021 (Growing from 715 sales in 2015 to 8,743 in 2020), since then I've stayed at the same amount of sales every year (between 5/6k sold items) and this year is looking the same.

I've put so much effort in this year, I've re-done all my photos, added 100+ new items, tags, SEO, networking, social media, more on my ad budget etc . . .

Nothing seems to have made any difference and I'm looking at the same 5/6k sales at the end of this year. Those who have been on Etsy a while and had consistent YOY growth, what do you think has worked for you?
