I noticed a lot of my clients know they have to invest in video content, but they don't know how and why.
I like to explain them what kind of content they could need and how to use video. I really like giving this speech. But I've never been able to explain it as precise as Alicia Collins and Megan Conley in this article: https://blog.hubspot.com/marketing/video-marketing.
Anything you need to know or want to know is here. Interesting stuff!
