I need to get my website approved on AdSense

I can suggest some ideas. Take time to rewrite the articles in your own words, Add your own thoughts even if summarising, share your own ideas and examples and If using others' work, give them credit.Focus on original content that helps your website and readers in the long run.

If articles are good enough, and you cover everything Google is looking for, you are good to go.

I have a 1 - 100% AI website that was approved without any problems.

Content must be first class, images, the whole structure of the website, SEO optimized, etc.

I was even on Discover for some 40+ days.

AI-generated content isn't a big problem unless it's really poor quality AI content.

AI-generated content is not problem. If you can provide the right information in the article and best of all if you get some organic visitors to your site every day. Then getting approval will be much easier.
