Re: DON'T USE TESTIMONIALS on Your Sales Page...
I would have to agree whether online or onstage, ase studies pack more of a punch, there are more details that might answer some fence sitters questions. they can connect with others who are dealing with some problem that your product is going to solve for them.
I love case studies! (tho an authentic testimonial isn't bad either)
Re: DON'T USE TESTIMONIALS on Your Sales Page...
Personally, I prefer unsolicited testimonials. In doing some outreach for my latest product, I was sending it out to potential JV partners and asking for feedback. I wound up with something unexpected, not feedback on what to do to make the product better, but actual testimonials, and ones from some well-known people in the industry. Needless to say, I was thrilled.
