Video is excellent for marketing because
1.It makes your product or service come alive. It;s the closest I can get to touching and playing without having the physical product.
2.It can work as a simple tutorial after I have bought yr product. Great for non-techies like me. How do I get your thing to work and do...
3.It's fun . People watch TV for fun, they equate video with fun and entertainment.
Here is an example of "How to" use a product I have bought the Zoom H2 digital recorder. 90 second video, enough!
N.B.I have no relationship with Zoom apart from being a customer.
Now it might seem a little cheesy but it does the job. Message to Zoom...Where is your YouTube Channel?
