https://www.etsy.com/listing/176491884/always-radiate-sunshine-yellow-original?ref=shop_home_feat_4I think your photography is great. I like the variety of photos in each listing. Could you fill the last two photo slots?
Your tags are lacking. I love this listing above, it's beautiful. But let's think like a buyer:
Will I search you by name? Probably not.
I'm assuming your "etsy promotion" tag is from a team? I put that in the search bar and you weren't in the first 5 pages of listings for that search. I think you're wasting valuable space with it. Unless you've seen sales with that search, let your product tags use that spot!
"Watercolor" is getting there but needs another word with it.
Maybe
bright watercolor
sunshine watercolor
yellow watercolor
And whatever you have in your tags you should also have in your title. Google will say "hey, that matches and we'll rank this high on search results."
Tags and titles is an art form in itself. I'm just now catching on to SEO and tags. My sales are good but I am excited to take it to the next level. I think by joining teams and studying up you will have great success. Continuous improvement!
