Testimonial vs Review: What's the Difference, and Which Do B2B Buyers Trust?

A review is an opinion the customer posts on a platform you don't control; a testimonial is one you choose and publish. Buyers trust reviews more, so here is how to make your testimonials believable, what the FTC says, and when a case study beats both.

Key takeaways

  • A review lives on a third-party platform and the customer controls it. A testimonial lives on your site or in your ads and you choose it.
  • Buyers discount testimonials because they know you picked the best ones. Reviews earn trust because the bad ones can appear too.
  • Under US rules a testimonial is a type of endorsement, and a review you paid or rewarded someone for counts as a testimonial.
  • To make a testimonial believable, name the person, keep their own words and add the detail a buyer can check. A short case study does that best.

The short answer: a review is a customer's own opinion, posted on a platform the business doesn't control, while a testimonial is a customer's words that the business chooses and publishes in its own marketing. Buyers trust reviews more because they can't be curated, so a testimonial only persuades when it carries detail a buyer can check.

What is the difference between a testimonial and a review?

The US Federal Trade Commission draws the line clearly in its guidance on the rule covering both. A consumer review is an evaluation submitted to and published on a site that exists, wholly or partly, to collect evaluations. A testimonial is an advertising message people are likely to believe reflects the experience of someone who used the product, and it can appear on a company website, in ads or on social media.

The FTC adds one point that trips people up: most reviews are not testimonials and most testimonials are not reviews, but a review you paid for or rewarded counts as a testimonial under the rule.

Which do buyers trust more, testimonials or reviews?

Reviews, because of control. A buyer looking at a wall of five-star quotes on your homepage knows you would never publish a lukewarm one. On an independent review site, the occasional three-star review is exactly what makes the five-star ones believable.

That doesn't make testimonials useless. It means a testimonial has to work harder. Compare:

Easy to dismissHard to dismiss
"Great product, highly recommend!", J.S."We stopped rebuilding the rota by hand every Sunday night." Jo Smith, Operations Director, a 40-person logistics firm
"Saved us so much time.""Month-end reporting went from two days to about an hour."
A stock photo and a first nameA real name, job title and company the buyer can look up

The right-hand column is still a testimonial. It is believable because it is specific and attributable, which is the same reason reviews are believed.

Is a testimonial the same as an endorsement?

A testimonial is one type of endorsement. In the FTC's wording, endorsements also cover statements by experts, celebrities and influencers, and the same rules apply: the words must reflect the person's honest experience, and any payment, discount or free product given in return has to be disclosed. Our guide to anonymous testimonials and FTC rules covers what that means when a customer won't be named.

Can you use a review as a testimonial?

Often, yes, with care.

  1. ●Check the platform's terms. Review sites set their own rules for quoting and displaying their reviews, and some offer approved widgets.
  2. ●Quote accurately. Trim for length with an ellipsis, but never change the meaning or make it stronger.
  3. ●Keep the attribution. Use the name and title shown on the review, and link back to it where you can.
  4. ●Ask the reviewer when it matters. For a homepage hero or an ad, a quick "may we feature this?" turns a review into a testimonial you have permission for.

Going the other way, from a story you already have to more reviews, is covered in turning case studies into G2 reviews.

Skip the writing entirely. StoryVoice interviews your customer with voice AI for 5 minutes, then writes the publish-ready case study for you — real quotes, hard metrics, and all.

Where should a B2B company use each one?

Buyer's questionBest proofWhere it goes
Is this company real and safe?Reviews on an independent siteA link or badge in the footer and on the pricing page
Does it work for people like me?A named testimonialBeside the claim it supports, on product and feature pages
Will it work for us, and what changes?A case studyProduct pages, sales emails, proposals
Can I defend this choice to my boss?A case study with a numberThe deal room and the business case

Reviews and testimonials both stop at a sentence or a paragraph. When a buyer is deciding, they want the before, the after and the person who lived it. That is a case study, and it is the format published proof favours: in our Customer Proof Index 2026, 84.8% of the 335 B2B software companies whose stories we could read named the customer and 83.6% quoted them directly. The Index is our own study of one directory's listings, so read it as directional.

How do you make testimonials as trusted as reviews?

Borrow what makes reviews believable.

  • ●Name the person. Full name, job title and company. If they can't be named, use concrete descriptors instead of initials.
  • ●Keep their words. Fix spelling, not voice. "It stopped being the thing I dreaded on a Monday" beats polished marketing copy.
  • ●Add the checkable detail. A before and after, a time frame, a number if they gave one.
  • ●Get written approval. It protects you, and the customer is far happier to be featured when they have seen the final wording.
  • ●Put it next to the claim. A testimonial about onboarding belongs on the onboarding page, not in a homepage carousel.

The fastest way to get all five is to interview the customer rather than ask them to write. StoryVoice does that end to end: you enter your customer's name and email in about two minutes, they talk to a friendly voice AI for about five minutes on their phone whenever suits them, and StoryVoice writes the case study, follows up and gets their approval by link. You also get a pull quote to use as the testimonial, a sales email, a LinkedIn post and an X post, for $39 a story against $2,530 and up for a written case study from a specialist agency.

The definitions of reviews, testimonials and endorsements, and the rule on fake reviews and testimonials, come from the FTC's "Consumer Reviews and Testimonials Rule: Questions and Answers" (ftc.gov) and 16 CFR Parts 255 and 465, read 9 November 2026. Customer Proof Index figures are StoryVoice's own research (1,000 B2B software company websites, crawled 2026-08-21, 954 usable, 335 with readable stories), published at storyvoice.io/research/customer-proof-index-2026.

Frequently asked questions

What is the difference between a testimonial and a review?

Control and location. A review is a customer's own evaluation posted on a platform built to collect reviews, such as G2, Capterra or Google, and the business does not choose what it says. A testimonial is a customer's words that the business selects and publishes in its own marketing, such as its website, ads or sales decks.

Which do buyers trust more, reviews or testimonials?

Reviews, as a rule, because buyers know a business only publishes the testimonials it likes. A mix of good and mixed reviews on an independent site looks honest. A testimonial earns the same trust only when it carries detail a buyer can check: a named person, their role, their company and a specific before and after.

Is a testimonial the same as an endorsement?

A testimonial is one kind of endorsement. The FTC describes a testimonial as an advertising message that consumers are likely to believe reflects the views or experience of someone who used the product. Endorsements also include statements from celebrities, experts and influencers, and the same honesty and disclosure rules apply to all of them.

Can a review become a testimonial?

Yes, in two ways. If you pay for a review or give anything for it, the FTC treats that incentivised review as a testimonial under its rule on reviews and testimonials. And if you take a review from G2 or Google and quote it on your own website, you are using it as a testimonial, so check the platform's terms and keep the wording accurate.

Should a B2B website show testimonials or reviews?

Both, in different places. Link to your G2 or Capterra profile so buyers can see independent reviews, and put testimonials beside the claims they support on your own pages. For the pages where a buyer is deciding, add a short case study, because it gives the context a one-line testimonial or review leaves out.

Are fake testimonials illegal?

In the US, yes. The FTC's rule on consumer reviews and testimonials, 16 CFR Part 465, bans businesses from writing, buying or selling fake or false reviews and testimonials, including ones that misrepresent what the person actually experienced, and courts can impose civil penalties for knowing violations. Other countries have their own consumer protection rules, so this is not legal advice.
