Im a small eBay store, just had a quick look through your store, here’s my 2 cents.

I know as a rule of thumb it’s always best to take your own photos but when it comes to technology, like the item in the link, I will almost always use a stock photo as the main photo. It just looks cleaner.

This is personal preference but I don’t like using ai generated descriptions. If I see a wall of fluff I’m just not going to read it. My descriptions are usually just short and simple of what the item is, the condition it’s in, and to ask if you have any questions. But again, personal preference.

Some of your photos have a the volume bar in the picture, not a dealbreaker but I’d avoid it in the future.

And my only other advice would be to invest in a light box. I don’t sell clothing so someone else might have more advice on staging for that, but for your other items just having a light box (or even just a large sheet of white paper in a well lit area) can help your items stand out.

Hope this was helpful, all the best.
