One of the simplest ways of including UGC is by having your top clients record a short testimonial and send it your way. You could have them upload to YouTube and embed the video onto your page, or you could upload and stream it from your server.
Another option is to take numerous testimonials and edit them into a single promotional video. Editing videos to be uniform can be difficult, though, as lighting, sound quality, and other elements will vary.
There are some third-party services like Billo that can help you to ease the process of receiving video testimonials from your clients. If you have just freshly opened your eCommerce store, then it can be hard to acquire testimonials so quickly. Luckily, Billo can also help you out with finding people who are willing to give an honest review of your product or service in front of the camera.
