Highest Paying YouTube Keywords?

I've been Googling for the best YouTube keywords all day for various niches without any clear solutions.

I've used keywordtool.io in the past, but it's VERY hit or miss. Same thing with VidIQ or TubeBuddy. I'll upload a video, optimize the description and video title, copy relevant tags from a successful video, and insert a sexy ass thumbnail with barely any tangible results.

I need something consistent and helpful.

What are the current, highest paying keywords in general? What are the best sites and methods to find them out? All of the advice I've read online is vague and it has been stated that even Google's Keyword tool doesn't work effectively.
