You asked for a testimonial and a happy customer replied within the hour: "Great product, highly recommend!" It feels rude to push back — they took the time, they were kind, they meant it. But you already know the problem. A one-line rave with no specifics is the weakest form of social proof there is. Prospects have read a thousand of them and skim straight past. The good news is that the customer who sent it is almost always willing to say more; they just answered the only question you actually asked, which was a vague one.
Going back for a richer quote is not greedy. It is the difference between a testimonial that decorates your page and one that closes a sale. Here is how to do it without making the customer feel like they failed a test.
Why the short version happens in the first place
People write short testimonials for the same reason they write short performance reviews: an open-ended request gets an open-ended, low-effort answer. When you ask "Would you mind sharing a testimonial?", the customer has to invent the structure, decide what matters, and self-edit — all unpaid work. So they default to the safest, fastest thing: a generic compliment.
The fix is almost never "ask again harder." It is to ask narrower questions that do the structuring for them. This is the same principle behind writing a testimonial request email that actually gets a reply — specificity in the ask produces specificity in the answer.
Lead with genuine thanks, then reframe the second touch
Your follow-up should never read as "that wasn't good enough." Open by accepting and appreciating what they sent, then position the second request as you doing more work, not them:
Thank you — that genuinely made my day. Would it be alright if I asked two quick questions to flesh it out into a fuller quote for our site? One-word answers are totally fine and I'll write it up; you just approve the final version.
Three things are doing the heavy lifting here. You thanked them sincerely. You capped the effort ("two quick questions," "one-word answers are fine"). And you offered to do the drafting, which removes the blank-page burden entirely — a tactic that overlaps with what to do when a customer asks you to write the testimonial for them.
The four questions that turn fluff into proof
You do not need a survey. Pick two or three of these, tailored to what you sell:
- What were you doing before, and what was annoying about it? This surfaces the "before" state — the pain a prospect recognizes in themselves.
- What specifically changed after you started using us? Push gently for a number, a time saved, or a concrete moment. "We cut our review-collection time roughly in half" beats "it's so much faster."
- Was there a moment you remember thinking 'this is working'? A scene is more believable than an adjective.
- Who would you tell to use this, and why them? This reveals the ideal-customer framing and often produces the most quotable line.
The aim is to move from adjective ("great") to evidence (before, after, number, scene). A quote built from even one of these reads as lived experience rather than a polite reflex.
Draft it for them, then get explicit approval
Once you have a sentence or two of raw material, write the polished version yourself and send it back for sign-off. Customers approve far more readily than they compose. Keep their voice, do not inflate the claims, and never add a metric they did not actually give you — inventing numbers is exactly the kind of thing that creates a problem later, like a testimonial that contains a factual error.
A simple approval message:
Here's how I'd write it up — feel free to edit anything or tell me to scrap it: "Before ProofShow we were chasing reviews over email and losing half of them. Now collection is automated and we've roughly doubled the testimonials we publish each month. I'd recommend it to any small team that hates manual follow-up." Happy as-is, or want changes?
That gives them an easy yes and a clear chance to correct anything, which protects both of you.
Know when a short testimonial is fine to leave alone
Not every one-liner needs expanding. A short quote from a recognizable name or logo can carry weight on reputation alone — "Indispensable. — Jane Okafor, VP Eng at [known company]" works because the attribution is the proof. The thin quotes worth fixing are the ones from unknown authors, because there the content has to do all the persuading. If you are unsure which of your quotes are pulling their weight, that is really a question of trust signals and author attribution.
The takeaway
A vague testimonial is not a dead end — it is a first draft. The customer already told you they like you; they just answered a loose question loosely. Thank them sincerely, come back with two or three narrow questions, do the writing yourself, and confirm the final wording. You will turn "great product, highly recommend" into a specific, credible story — and the customer will feel helped, not audited.
