Multiple rejectections!!

Upscaled from what exactly?

When you upscale bad pixels, it just makes more bad pixels. 

We need to see one or two rejected assets and the reasons for refusal. 

Always check GenAI for accuracy and other rendering mistakes. Fix all errors if you can, or discard & start over.

Meanwhile, read the submission requirements from your Contributor User Guide.  Stock expects the highest visual & technical quality for GenAI as they do for other assets.

AI content is super saturated. Editing images and creating content that is new, fresh, and marketable is also important. Artsy AI images have their own space and platforms.

Rejections rarely have anything to with the number of keywords one uses. As suggested, post a couple of rejected assets here, along with the reason given for rejection.

Please also post the image you uploaded to Adobe Stock to the community.
I will check to see what the issue is.

Hardly. Unless you tell us what the rejection reason is and show us two or three of your rejected assets.
