7 Ways to Collect Customer Testimonials

Collecting testimonials is not a writing problem. It is a logistics problem: the praise already exists, scattered across an inbox, a chat thread and a call you did not record.

Here are seven ways to gather it, what each is genuinely good at, and where each one fails.

1. Email

Best for: client work, B2B, anything with an invoice attached to it.

Email is the default because it is where professional relationships live. It is also easy to ignore, so timing matters more than wording — the week the work lands, not the month before your launch.

Ask one specific question rather than requesting "a testimonial", and include a link so nobody has to compose a reply. A request that requires the recipient to write an email gets answered at the rate emails requiring writing get answered, which is badly.

2. SMS or WhatsApp

Best for: local business, trades, coaching, anything where you already message the person.

The response rate is far higher than email, because the medium is informal and the reply is expected to be short. The catch is that it feels intrusive if you have not messaged them before — sending a first-ever text to ask for a favour reads badly.

Keep it to two lines. A long message in a chat window looks like a form letter and gets treated as one.

3. LinkedIn

Best for: consultants, freelancers, B2B services.

Two advantages: the person is already thinking professionally, and their reply carries a real name and job title attached to a verifiable profile — which makes the resulting testimonial more credible than an anonymous one.

Worth knowing: a LinkedIn recommendation and a testimonial are different things. The recommendation lives on their profile and does you good there. Ask for the testimonial separately, with a link, if you want it on your own site.

4. A QR code

Best for: anywhere physical — a shop counter, an invoice, a receipt, packaging, an event table.

Underused, and genuinely effective for businesses where the customer is standing in front of you. The moment somebody is most pleased is often the moment they are paying, and a QR code catches that moment. Anywhere else, the pleasure has already faded.

Print it larger than feels necessary, and put one word above it explaining what it does. An unlabelled QR code gets scanned by almost nobody.

5. A button on your own website

Best for: products with logged-in users, communities, membership sites.

If somebody is already using your product and enjoying it, a small "share your experience" link in the right place catches people at the peak of their goodwill — after a successful action, not on a settings page.

The failure mode is putting it in the navigation, where it competes with everything else and is seen by people who have not formed an opinion yet.

6. Reusing what already arrived

Best for: everybody, and almost nobody does it.

You have already been paid the compliment. It is in a Slack message, an email signed off "honestly, this has been brilliant", a comment on a post. Most businesses collect testimonials from scratch while ignoring a year of praise already sitting in their archives.

Two rules. Ask before publishing — a private compliment is not consent, and a one-line message asking permission almost always gets a yes. And do not edit the meaning, only the typo.

7. A hosted collection link

Best for: all of the above, because it is what you put in the other six.

This is not really a seventh channel; it is the thing that makes the other six work. A link you can send by email, paste into WhatsApp, encode in a QR code or put behind a button on your site — and every response arrives in one place instead of six.

What matters is what happens on the other end. The person should not need an account, because every step between the ask and the answer costs you replies. And the answer should not be public automatically, because the thing people are actually nervous about is not writing something — it is losing control of it.

What to expect

Being honest about numbers, because the usual advice is not.

Asking once, late, by email, with no link and no specific question gets you a response from roughly one in ten people. Asking in the week the work landed, with one specific question and a link, gets you something closer to half — and the answers are longer and more useful.

The difference is not persuasion. It is timing and friction.

Where to start

Pick the channel you already use with that customer, ask one specific question, and send a link rather than requesting a written reply.

Set up a collection form, or read how to phrase the ask so it does not feel awkward.
