I know it looks like garbage and reused spam.
But I had no issues for like 1+ year. It made me around 6000€. No problems.
The copyrighted clips YT detected in my vids were deleted by YT, there is 1 button that appears if copyrighted content is found.
And YT asks permission to remove themselves. I always did this. Its literally 2-3 secs.
You make the 2-3 first minutes good, add clips, good script start, make everything as best as you can and the rest are just slides.
If you can then use clips in the rest of the video too. About some persons there is very few clips, if any..
And yes, better content is a must have for longterm. I analyzed different niches for 2 hours yesterday..
Found very interesting niches, and even unique niches, I havent seen before. With very good views.
Some have AI clips with stock images. But I have to analyze further.
