Testimonial (review) videos
These are just what they imply; a testimonial from a satisfied customer explaining to the world what a great experience they had with your company. This is probably the single best way to create trust from your reviews as video is more believable than ordinary written reviews.
Plain and simple, this is a video that promotes your company, service or product. This is where you make special internet-only offers and provide a sweet deal on a service call or repair. Don't mess around with $10 or $15 coupons; give them something super enticing to get your foot in the door and keep them as a client for years to come.
