The infographic below should convince you that you need to include video into your marketing mix. Think about your own experiences. What is more entertaining? Reading through a PDF or watching a video, all things being equal?

One item that you should pay close attention to is the one that states "Customers Expect Video Content". So it really is no longer even a choice. It's a must. And if you have shied away from including videos before because you are not aware of how to do it, then outsource the process.
Another great take away from this infographic is the item that states "Visitors who watch a video are reported to stay on sites Twice as Long & look through twice as many pages". That means using video can help lower your bounce and exit rates. That's pretty cool (and can be profitable too!)
