Hi @falkor4eva
I definitely understand your concern and this is a sensible question to ask. While I can’t speak on behalf of Google and how they review rankings, I can share their very detailed doc on this topic for you to review: Google Search’s guidance about AI-generated content.
Quoted from their FAQ section:
Is AI content against Google Search’s guidelines
Appropriate use of AI or automation is not against our guidelines. This means that it is not used to generate content primarily to manipulate search rankings, which is against our spam policies.
I hope this information will help ease your mind about using AI automation in the future!
