If a video is going viral, should I post another while it’s still climbing or should I wait for the video to die down?

in my experience, you could post a video relating to the one going viral. Like if a comment is asking a question, make a video regarding that to also drive traction to the original video.

Literally does not matter. If u post it sooner you’ll get more views but the number is inflated because people went on your account from the viral one. It’s not high because it’s on the for you page for loads of people, unless it is actually a good video and also gets lots of fyp views

Make more videos replying to comments on the main video. Can literally be a reaction video where you don’t even talk and just react to the first video going viral lol. I did that and got 500K views on the back of a viral 1M video - the SpaceX rocket catch last year lol
