Testimonial videos are a great way to show your potential clients what your current clients think of your service. These days, seeing someone sprouting off on camera about how good they are is simply seen as pretentious showboating. So what better way to promote your business than to have someone else talk it up for you? It highlights the commitment and professionalism you strive for, the lengths you go to serve your clients and the reasons why people should be dealing with you. A testimonial video used as part of a sales pitch can often be the difference in getting the sale.
