Is it possible that ebay is dead right now ?

The first 6 months this year I was focussed on sales (while having my ebay store still) but now I put more effort, listed new paintings and can't believe no one is buying.

I am asking myself what else I can do? Where can I found out where to list, online I came across artprice, where I will pay 400EUR per year to list.

Where else I also can list besides etsy ?

Every help is appreaciated.

you can list on amazon, it will be better for you to list it everywhere, if the product you are selling is your own.

Maybe start with own page, shope, blog to show Your items and then link them, social media, groups etc.

Check the competition, the niche, the category, optimize your title, prrice your paintings competitively and eventually you'll get sales.
Other places you can list: FB Marketplace, Etsy, Onbuy, Amazon.

eBay still good for now mate .
You should choose the products which people like . Many sales or less sale , it's depend on niche/demand .
Beside Etsy , you can list them on Amazon and Facebook Marketplace .
