The client is happy.
So happy, in fact, that she takes a minute to tell you how pleased she is with your work.
Thank her for telling you. But don’t stop there. Ask her if you can use it as a testimonial.
In fact, offer to “ghostwrite” her glowing comments so she doesn’t have to. And explain that you’ll submit the testimonial draft for her approval before publishing.
Most (if not all) clients will say yes … if you ask them at that moment.
You’ve stacked the deck in your favor by making the request when she’s thinking about you and your excellent work. And you’ve taken the hard work off her plate by offering to transcribe her comments.
Train yourself to do this every time you get praised. It won’t be long before you have five or six excellent testimonials.
