YouTube video and Facebook Ads

Dear Experts, How could i promote my YouTube videos by using Facebook ad to get Good ROI. Is there any tutorials for That, If Yes Kindly Share.
Thanking You in advance for your kind courtesy.

Well you can’t promote a channel to get subscribers directly. Depending on your strategy, this might make sense. But, if you want to be successful on Facebook, you might choose to upload your videos to Facebook to be able to track the views directly on FB and make it easier to share and promote them as part of the Facebook advertising machine.

Start by setting up an ad campaign and test things on a small budget. Review the gathered data and adjust accordingly.

It might also just be better to promote your YT video with YT ads (Google Ads) since it's the same platform.
