"Similar content in our collection" problem

Here's what Adobe Stock has to say about 'Similar Content.'

Keywords, titles & descriptions can be a factor. But not the only one.

AI is trained on content in a database. Similar content comes with the territory. I often see the same hairstyles, body types, facial features and clothing styles used again & again. There's nothing random about AI. It has rules it follows to keep it from derailing. 

I don't recall who posted this comment/advice, but a while back I read that using your own keywords and avoiding using only the keyword suggestions Adobe supplies might be a way to avoid "Similar content in our collection" rejections. I thought this to be good advice.

Some think that the keywords and the title has a major influence on the similar refusal.

Check the multiple posts on this subject here.

"Does the title, keywords, or other metadata added to the image influence this 'similar content' rejection?"

That is the working theory. 

How can we avoid this issue when uploading images in the future?

Try more specific keywords while putting more generic keywords at the bottom of the list.

Also, how can we check whether the image we created has similar content already available?

In my experience, it doesn't matter. I've had what I believe are unique assets rejected as similar content, while assets that I was sure would be rejected for the same reason were accepted.

[Edit: changed rejected to accepted directly above; it's late.]
