Testimonials and Case Studies

Collect and use real testimonials and case studies ethically: consent, typical-results context, general FTC endorsement guidance and a case study template.

Proof is one of the most persuasive parts of any sales page, which is exactly why it has to be real. A single honest story from a genuine customer does more for you over time than any number of polished, exaggerated claims. This page shows you how to collect real proof, get proper consent, present results responsibly and turn your best client stories into case studies.

What’s in the box: when and how to ask, questions that get useful answers, a consent checklist, typical-results disclosures, general FTC endorsement principles, a case study template and AI prompts.

The rules of real proof

Real people

Every testimonial comes from an actual customer or client, in their own words. No invented names, stock photos or composite characters presented as real.

Real consent

They agreed to how and where you will use their words, name and image, and they can change their mind.

Real context

Standout results are presented with context about what is typical, so nobody is misled.

Real disclosure

If you gave the person anything of value (a free product, a discount, a payment), that connection is disclosed.

When to ask

Timing matters. Ask when the experience is fresh and positive:

  • Right after a client reaches a milestone or tells you something went well.
  • At the end of a cohort, program or coaching engagement.
  • When someone sends you a spontaneous thank-you (ask if you may share it).
  • A few weeks after purchase, via an automated feedback email.
  • During beta programs, where feedback is part of the deal.

How to collect useful testimonials

  1. Use a simple form. A short survey with a few open questions and a consent checkbox.
  2. Ask specific questions. “What was going on before you joined? What did you do inside the program? What changed? Who would you recommend it to?”
  3. Welcome honest answers. Invite constructive feedback too. Mixed reviews make the positive ones more believable, and you learn what to fix.
  4. Offer formats. Written, a short video, or a quick recorded call you transcribe.
  5. Edit only for length and clarity. Never change the meaning or add claims. Send the edited version back for approval.
Pro tip: the most persuasive testimonials name a specific “before” and a specific “after” in the customer’s own words, and often mention an objection they had (“I was worried I would not have time, but…”).
  • Written permission to use their words, stored somewhere you can find it.
  • Agreement on how they are identified: full name, first name, initials, business name or anonymous.
  • Separate permission for photos, video or their business logo.
  • Clarity on where it will appear: sales page, emails, social, ads.
  • An easy way to withdraw permission, and a process for removing it everywhere if they do.
  • Extra care for sensitive topics such as health, finances or relationships. Anonymize by default and never share private details from coaching sessions.

Typical results and honest context

If a testimonial describes an unusually good outcome, many readers will assume it is what normally happens. That is why you should give context. You do not need a wall of legal text, just honesty.

Instead of Try
Showing only your single best result Showing a range of real stories from different kinds of customers
Implying everyone gets that result “Results vary based on effort, experience and circumstances. Here is what [name] did.”
Hiding what the person did Explaining their starting point and the work they put in
Income or health outcome claims as headlines Focusing on skills learned, clarity gained and experience in the program
Heads up: health, financial and legal outcomes deserve extra caution. Avoid presenting a client’s earnings, weight loss or medical results as something others should expect, and include appropriate disclaimers. When in doubt, ask a qualified professional.

FTC endorsement guidance, in general terms

In the United States, the FTC’s endorsement guides set out principles for testimonials and reviews. In general terms, and not as legal advice:

  • Endorsements must reflect the honest opinions and actual experiences of the person giving them.
  • You should not use a testimonial to make a claim you could not legally make yourself.
  • If results shown are not what people can generally expect, you need to make clear what typical results are, not just add “results not typical.”
  • Material connections, such as payment, free products, or a family or business relationship, must be clearly disclosed.
  • Fake reviews, buying reviews, and suppressing honest negative reviews are prohibited practices.

Other countries have their own rules. Review the FTC’s official guidance at ftc.gov and talk to a qualified attorney about your specific situation.

Case study template

A case study is a longer, structured story of one customer’s experience. It is ideal for sales pages, emails and webinars.

  1. Who they are. A short, consented description: role, situation, anything relevant.
  2. The starting point. What was hard, what they had tried, what they were worried about.
  3. Why they chose you. What made them decide, including any hesitation.
  4. What they did. The steps they took, the parts of your program they used, the effort involved.
  5. What changed. The outcomes in their own words, with honest context.
  6. What is next. Where they are going now.
  7. A quote. One strong line in their words, approved by them.

Where to use your proof

  • Near the top of your sales page, and again next to the price and the FAQ.
  • Inside launch and welcome emails, one story per email.
  • In webinar and workshop slides, with the person’s permission.
  • On your About page, to show who you have helped.
  • In social posts, only where the person agreed to social use.

Keep a simple proof library (a spreadsheet works) listing each testimonial, the consent given, where it may be used and the date collected. Review it periodically and retire anything outdated.

AI prompts for proof

AI angle: AI can draft your feedback form, organize interview notes and structure case studies. It must never invent a testimonial, a quote or a result. Real words only.
AI Prompt

Create a short customer feedback form for [product]. Include 5 open questions that capture before, during and after, one question inviting constructive criticism, and a consent section with options for how they can be identified.
AI Prompt

Here is a transcript of my interview with a client who has approved being featured: [paste]. Organize it into a case study using this structure: who they are, starting point, why they chose us, what they did, what changed, what is next. Use only facts and quotes from the transcript. Do not add or exaggerate anything. Flag any claims that may need a typical-results note.

Keep going

Put your proof to work on your sales page (try the Sales Page Builder), in your launches and in your evergreen funnel. And remember, the best way to get great testimonials is to help people get real value, which is what Retention and Upsells is all about.
