Video content showing what a business is does, the products or services that it provides, it's values, insights, the list is almost endless, all help to break down barriers and let potential customers see what the business is about rather than having to read about it.
It can also help to build up a level of trust. Humans are visual creatures and more people prefer to learn about a product or service by watching a video rather than reading about it. Eg. A website visitor, seeing an interview of a business owner talking passionately about their business, can decide if they like the person that they might well be dealing with and being paying money to. Like we've said, videos can help break down barriers.
