So, I have to confess that I often forget to do this, even though I know I should!

I am talking about changing your MP4 filename BEFORE you upload it to YouTube.

It should include the keyword that your video is about.

This gives you two more opportunities for traffic - it tells both Google and YouTube's algorithm what your video focuses on. 

Here's an example - the screenshot below is my best-performing Short for one of my YouTube channels.

But, how does it tell Google and YouTube what my video is about - it could be anything!

And, unfortunately, you cannot change the filename after you have uploaded it.

I hope this helps, thanks for reading!
