The truth is that if you found 100 high payng keywords, by next week they would have changed because keyword demand varies from week to week and month to month. My advice is to target a niche and then create high quality content that will be attractive to your readers. Don’t download junk articles from article sites
The best niche is in insurance and finance. You can hire writers to write many articles using the high paying keywords.
That does not guarantee that Google will show those expensive ads on your website. You may get those cheaper ones and earn lower.
Man These things keep changing. What u Fount may not be the High Paying Keywords in future. But there are some Steady Keywords witch Fluctuate a little. Better stick to those Key Words.
