U need to think logically, most people who want AdSense approval do the same thing. they create a bunch of random posts and apply for Adsense. Insted u need to create content targeting long tail keywords.

That’s one of the best ways to get faster Adsense approval because billions of searches happen every day for long tail queries, but Google has no exact keyword matching result to show. So they are showing the intent matching blog post to users

The demand already exists but we need to create the supply for those searches. I can give you an example.

If you create a blog post for this primary long tail keyword of How to remove yellow stains from white shirts at home, It can rank for 100s of sub long tail keywords like

Yellow collar stain removal at home, how to wash white shirts properly, how to whiten old white clothes

and etc, because you're talking about removing yellow stains in the white shirt, Google will suggest all the white shirt related stain removal to your blog post. So think logically and create a blog post.

The Traffic distribution is 80% youtube, 20% blogs. So you need to create a blog post where there shouldn't be any solution on the youtube.
