Need help with youtube

Hi all?
I plan to work with Cpa through youtube.
I have one question,

Someone tell me best keyword research process for youtube to find keywords had low competition and medium searches in month?
I'm newbie and researched for that but I feel confused.

I don't know keyword in google search and youtube search are same or not(search volume, competition...) because most free tools in internet show me keyword of google search.

Any suggest? Very Appreciate that.

much people in my country use vidiq for research keyword
