My YouTube Strategy

Do you think this strategy will work?

I will create 20 different videos. Each of them will be slightly modified and duplicated 30 times. So I will have 30 different versions of each video = 600 videos total.

I will have a list of 30 keywords and will target each keyword with 20 different videos.

Any tips or advice on how I can improve this strategy? do you think it will work?

The niche is currently making me money with very few videos.

well if its currently making you money then yeah it is a good startegy. scaling up....its a numbers game,i guess.
