"Now that we've presented all the main features and benefits of the product, we're moving on to another testimonials section, to bolster our claims with some social proof."
"A great, eye-catching testimonial should include a heading (use the best part from the testimonial for this), the testimonial text itself, an image and the name of the testimonial author."
"You can use this testimonial example if you don't have an image of the testimonial author. Whenever possible, it's recommended that you get an image to show along with the testimonial, though. It goes a long way to adding more credibility."
