Why? Because this is the reality.
One of the so many SEO tactics is to publish own videos to YouTube linking to the original content. Right? Wrong.
I learned that any sales videos and your opt-in videos must be kept in your own server.
The reality is that your YouTube videos might easily outrank your own website content - your own web property.
And if so, why should you do that? Doing that, it might be YouTube displacing you rather than a competitor displacing you.
I think it somehow not ethical, but making a choice letting this giant this capacity is everybody’s own fault.
