When you watch a promo video, you get more than a few lines of texts and a couple of Photoshopped pictures. Promo videos often feel real when you see the character's facial expressions, body language and even hear their vocal tones and how they emphasize different thoughts. The combination of seeing and hearing encourages trust and loyalty, especially in this day-and-age where business is done virtually rather than face-to-face. A promo video gives your business a bit of personality.
