Extras are unique to your needs — you might benefit from behind-the-scenes footage, a quick photo session, or certain types of b-roll. Get it done! Any content you can create on set during production will only benefit you. It can add more long term value to your clients and give you more content to post. If you work with an agency, ask them what they can do. You might even ask for raw video footage so you can continue editing and repackaging your video for future use. Think about your needs and see what you can do!
The engage stage is the hardest to correlate to cold, hard sales. Because users aren’t necessarily looking to purchase here, they can watch your video, learn some information, and not come back to your website for a long time. Try to implement detailed tracking information to show you big-picture user behavior; drop cookies and retrieve path information for every person who views your video or goes to your site. Then, you can see what percentage of visitors end up buying from you.
