Because your definition of a “conversion” is up to you, the metrics to measure here can vary. Generally, a strong video will have a high percentage of clicks, calls, signups, or sales. A strong video may also lead to more interaction with your brand, meaning your video has maintained the viewer’s attention, but they may need just a little more information before making their decision.
Trust is the foundation of conversions and sales. But building trust should be a goal on its own. The whole concept of content marketing is based on trust and creating long-term relationships. Stop selling and let the people come to you by providing them interesting and useful information. I couldn’t have said it better than Mark Schaefer, the Executive Director of Schaefer Marketing Solutions:
Instead, place a laptop below the eye-line of the camera. Break the script into short paragraphs and record it section by section until you capture a great take of each. If you plan in advance when the final video will show b-roll (supplementary footage or screenshots), you can have your talent read those lines directly off the laptop like a voice over.
When it comes time to shoot, clear out unnecessary people from the room and turn off the overhead lights. With your three-point lighting setup, there will be no need for those harsh fluorescents. When — and only when — everything is set up, call in your talent. There's nothing worse than being nervous, and then having to anxiously watch as lights are turned on and the camera is tested.
