Marketing on YT: 100 views in less than 2 hours!

We have been using YT for sharing 'how to' videos related to the product. Today, I published a video with useful funda for students, who are part of our target audience along with teachers. The video is receiving a good response and crossed 100 views in 2 hours.
Here is what I did.

• Recorded the video at home
• Hired an editor from freelancer
• Posted on YouTube
• After posting the video, I also shared on Reddit and Facebook. (No paid ads run)

I also added the video to the product website,

On first impression on the response to video is pretty good. It is ~10X the response I have received in the recent past for Medium and Linkedin articles. Would like to hear from Indiehackers who have successfully used video marketing on their experience.
