Use video testimonials they are very powerful!
My tip: Because you all are already at an event it is going to be EASY… have your phone or small recording device ready and get video testimonials from:
1. The planner
2. A couple of the audience members.
Many of you won’t want to go and ask but the worst that can happen is they will say No, which is not likely.
You can also ask the planner before the event that is they enjoyed the presentation you would like to do a quick 30-40 second (or shorter) testimonial that way they have been notified and there are no surprises. Get as many as you can they are a very powerful marketing tool for you.
