Just as the name suggests, an explainer video explains how a business, or product works. It communicates with viewers in a simple and straight forward manner so that they have a better understanding of your brand and what you have to offer. From learning how to use a particular app on your smartphone, to unraveling how your vacuum cleaner works, why a particular cocoa bean has a richer flavour, or even how a particular beer is bottled — explainer videos can cover just about any product and service.
