“You will be thrilled if you hire ABC Corp.”
“If you work with the marketing team at XYZ management, you’re guaranteed to see better revenues.”
“Clare is the best graphic designer in Phoenix, hands down.”
Testimonials from enthusiastic fans are great. But when they say things they can’t back up, they lose credibility.
If your clients over-the-top sentences like these, say “gosh, thanks!” Then do a minor edit. Add an “I believe that” or “I’ll bet that” (or some modest qualifier) that lets their love for you shine through, without creating a credibility gap.
