If your business has front line staff that regularly engage with your customers, Staff Intro videos can be very helpful in heping your customers not only put a face to a name or voice, but also to get to know who your staff is. We like to have people talk about their hobbies, memorable experiences in their lives, their qualifications, etc.
Think of these videos residing on your About Us or Sales pages. Perhaps you have certain staff that specialize in a particular product or service; you can put their staff intro video on the sales page for that product or service. This makes it easy for the buyer to learn about their sales person and understand who they will be talking with.
