How to Write Testimonials That Sell (With Templates to Send Clients)

How to get testimonials that sell: the interview questions, request email templates and draft-for-approval process copywriters use to get specific customer quotes.

By Mehdi Hassan8 min read

The short answer

To get testimonials that help conversions, don't ask customers to write one. Interview them for 15 minutes with structured questions about their situation before, the moment they decided and what changed, then draft a short quote from their own words and send it for approval. Specific, attributed quotes do far more work than generic praise.

Key takeaways

  • Asking 'can you write us a testimonial?' gets compliments. Asking structured questions gets evidence.
  • Interview first, then draft the quote yourself from the customer's own words and send it for approval.
  • The best testimonials name a before, an after and a detail only a real customer would know.
  • Ask at a moment of success: after a launch, a renewal or a thank-you email, not at random.
  • Always get written approval, use full attribution and never change the meaning of what was said.

Most testimonials on B2B sites say some version of 'great to work with'. They're polite, true and almost useless, because they don't answer any doubt a buyer has. This guide shows how copywriters collect quotes that do the work: the timing, the email to send, the interview questions, how to turn answers into a quote, and how to get it approved. It's one part of our broader guide to social proof on landing pages.

Why do most testimonials fail to convert?

Most testimonials fail to convert because they're vague, unattributed or about the wrong thing. 'Amazing team, highly recommend' tells a visitor the customer was happy, but not why, with what, or whether the visitor would get the same result. Buyers skip it the way they skip stock photos.

The root cause is the request. When you ask a busy customer to 'write a few words', they write the fastest polite thing they can. They aren't copywriters, and they don't know which of your claims needs supporting. The fix is to take the writing off their plate: you ask questions, they talk, you draft, they approve.

How to get testimonials: when is the best time to ask?

The best time to ask for a testimonial is right after a customer has felt a win: a launch, a milestone, a renewal, a support issue solved quickly, or an unprompted thank-you message. At that moment the result is fresh and their goodwill is high, so they say yes more often and remember specifics.

  • After an unprompted compliment. Reply with thanks and ask if you can use it, or turn it into a short interview.
  • After a measurable milestone. A first month of results, a project shipped, or a goal hit.
  • At renewal or expansion. A customer who chose to stay has already made the case to themselves.
  • After a strong support moment. Quick, personal help is often what customers remember most.
  • Not right after signup. They haven't experienced the value yet, so you'll get expectations instead of outcomes.

What should a testimonial request email say?

A testimonial request email should be short, specific about what you're asking, and make it easy to say yes. Ask for a 15-minute call rather than a written quote, explain that you'll draft the text for their approval, and say where it will appear. Make declining easy too, which makes accepting more comfortable.

Template: the request email

Subject: A quick favor, 15 minutes

Hi [first name], it was great to see [specific win, such as the launch last week]. Would you be open to a 15-minute call about how it went? I'd like to turn a few of your thoughts into a short quote for our website.

You won't need to write anything. I'll draft the quote from our conversation and send it to you to edit and approve before anything goes live. If now isn't a good time, no problem at all.

Would [two specific time options] work?

[Your name]

Template: the follow-up when they prefer writing

Thanks, [first name]. To save you time, here are four short questions. One or two sentences each is perfect, and I'll shape it into a quote for you to approve.

1. What was going on before you started working with us? 2. What made you decide to go ahead? 3. What's different now? A number or example is ideal. 4. Who would you recommend us to, and why?

Thanks again. I'll send the draft back within a couple of days.

Which interview questions get specific testimonial quotes?

The interview questions that get specific testimonial quotes ask about the situation before, the decision, and the change after, in that order. This mirrors the story a buyer needs to hear: someone like me had this problem, chose this product, and got this result. Open questions and follow-ups like 'can you give me an example?' do most of the work.

  1. The before

    What was happening before you started? What had you already tried? What was that costing you in time, money or stress?

  2. The hesitation

    What almost stopped you from going ahead? What were you worried about? This answer is gold, because it mirrors your prospects' objections.

  3. The decision

    What made you choose us over the alternatives, including doing nothing?

  4. The experience

    What was working together or using the product actually like? Anything that surprised you?

  5. The after

    What's different now? Can you put a number on it, or give me a specific example from last week?

  6. The recommendation

    Who would you recommend this to, and what would you tell them?

Record the call with permission and get a transcript. The best lines are rarely the answers to your main questions; they're the asides, like a customer saying 'I stopped dreading Mondays' or 'I sent the page to my CEO without changing a word'. Those phrases are also a source for your page copy, which is why we treat customer interviews as part of writing a value proposition, not just collecting proof.

How do you turn interview answers into testimonial examples that sell?

You turn interview answers into a testimonial by picking the strongest before-and-after from the transcript, keeping the customer's own words, and trimming it to one to three sentences. Edit for length and clarity only. Never add claims they didn't make, and never change numbers.

The examples below are illustrative rewrites, not real customer quotes. Each shows the same raw interview answer turned from a weak quote into a strong one, and what the stronger version does better.

Illustrative weak draft

Illustrative stronger draft

What improved

'They were great to work with.'

'We'd rewritten our homepage four times. The new one finally explains what we do, and I haven't touched it since.'

Before, after and a detail

'The tool saves us time.'

'Approvals used to take three email threads. Now they're one click, and nobody chases me on Fridays.'

Concrete task and feeling

'Highly recommend.'

'If you're a two-person ops team drowning in spreadsheets, this is the one to try first.'

Names who it's for

'Great support.'

'I posted a bug at 9 p.m. and had a fix and a reply from an engineer by morning.'

Verifiable specific moment

Notice that the strong versions answer doubts: is this fast, is it for someone like me, will they help when something breaks. Once you have a few, place each one beside the claim it supports. A quote about speed goes next to your speed claim, not in a carousel at the bottom. For quotes that sit next to the button, our guide to CTA button copy covers the words around them.

How should the testimonial approval process work?

The testimonial approval process should be written, simple and on the customer's terms. Send the draft quote with exactly how it will appear: their name, role, company, photo and the page it's going on. Invite edits, ask for explicit written approval, and keep that approval on file.

  1. Send the draft in context. A screenshot or mockup of where it'll appear helps them see it's professional.
  2. Invite edits. Say 'change anything that doesn't sound like you'. Most people change little, but they appreciate being asked.
  3. Confirm attribution. Full name, role and company, and ask whether you can use their logo and a headshot.
  4. Check company policy. Some companies need marketing or legal approval for public endorsements. Ask early.
  5. Store the approval. Keep the email thread. If someone leaves their company, check whether they're happy to stay attributed.

If you offered anything in exchange for a testimonial, such as a discount or a gift, disclose it. In the US, the FTC's guidance on endorsements expects material connections to be disclosed, and other regions have similar rules. Honest disclosure rarely hurts conversion, and hiding an incentive can.

What if customers say no or never reply?

If customers say no or never reply, it's usually timing, effort or policy, not that they're unhappy. Follow up once after a week, offer the written-questions option, and ask whether an anonymous quote by role and industry would work if their company restricts endorsements. Then move on and ask someone else.

While you build up a set, there are other honest proof sources: usage numbers, a pilot result, or the team's track record. Our guide to social proof for startups with no customers yet covers those. Once you have a strong quote and the full story behind it, it can become a full case study page, and the best companies to feature on a logo wall are often the ones who gave you a quote.

Frequently asked questions

Is it OK to write a testimonial for a customer?
It's fine to draft a testimonial for a customer as long as it's based on what they actually said and they approve it in writing. Copywriters do this routinely because it saves the customer time and produces clearer quotes. What isn't OK is inventing claims, changing their numbers, or publishing without approval. The words should be faithful to their meaning and recognizably theirs.
Should I offer an incentive for testimonials?
You can offer a small thank-you for a customer's time, but disclose any incentive wherever the testimonial appears, as endorsement rules in many regions expect. Incentives tied to positive content are riskier than those offered for any honest feedback. In B2B, most customers agree because they like the product and the request is easy, so lower the effort before adding a reward.
How long should a testimonial be on a landing page?
A testimonial on a landing page works best at one to three sentences, roughly 20 to 50 words. That's long enough to include a before, an after and a specific detail, and short enough to read at a glance. If the customer's full story is longer and stronger, link from the short quote to a case study page.
Where else can I find testimonials I already have?
You likely already have testimonial material in thank-you emails, support tickets, Slack messages from customers, sales call notes, review sites and social media mentions. Search your inbox and support tool for words like 'thanks', 'love' and 'finally'. Any of these can become a quote, but always ask permission before publishing, even if the original was public.
Do testimonials need a photo?
Testimonials don't strictly need a photo, but a real headshot with full name, role and company makes a quote far more believable. Faces signal that a real person stands behind the words. If a customer prefers no photo, use their company logo instead. Never use stock photos next to testimonials, as visitors spot them and they undermine trust.
