How to turn reviews into ad copy

Mine your product reviews for hooks, proof and objections, then turn them into ads that quote customers honestly and stay inside the FTC's endorsement rules.

What this is for

Your reviews already contain the sentences an ad needs: the doubt a shopper had, the moment they decided, and what happened after. Customers describe the product in plainer words than you would, and those words read as proof rather than a pitch.

US rules allow it. The FTC says a business can take what customers said about the product and use it in advertising, as long as the endorsement is honest and represented fairly. This guide takes you from a review export to a set of ads you can test. source, checked 28 September 2026

Time needed and what you need

Time needed: about 2 hours. Sorting the reviews takes most of it; writing the ads from a sorted sheet goes quickly.

  • A full export of your written reviews from your review app, with star rating, date and whether the product was given free
  • Your review app's terms, to check how you may reuse reviews in ads
  • A spreadsheet with columns for the review, the bucket and the ad line
  • The persona cards for your store, if you have them

The steps

Treat every review as evidence you are quoting, not raw material you can rewrite.

1. Export the reviews and keep only the detailed ones

Pull every written review into the sheet, then filter out the ones that say nothing specific ("Great!", "Love it"). You want reviews that name a situation, a worry or a result. Keep the star rating and date beside each one so you can check later that you did not pick only the glowing outliers.

2. Flag reviews from people who got something in return

Mark any review written by someone who got the product free, a discount for reviewing, or who works for you. If you quote one in an ad, the ad has to say so, because it changes how much a reader trusts it. source, checked 28 September 2026

The simplest rule: build your ads from reviews by paying customers, and set the flagged ones aside.

3. Sort sentences into four buckets

Copy single sentences, not whole reviews, into a bucket column. One review can feed three ads.

  • Doubt: what they worried about before buying ("I was sure it would be too small")
  • Trigger: why they started looking ("my old one finally broke")
  • Result: what happened after ("no more pulling on walks")
  • Comparison: what they used before and why this is different

4. Choose lines that describe a typical experience

A quoted result is read as a promise. The FTC treats a customer's specific result as something every viewer will expect, and a small print line does not undo that. source, checked 28 September 2026

So prefer lines about ease, fit, quality, delivery and service, which most buyers share, over a dramatic outcome only one person had. If a result line appears again and again across your reviews, it is a candidate; if it appears once, leave it out.

5. Turn each bucket into a part of the ad

A doubt line makes a strong first sentence, because the reader who shares the worry stops. A result line becomes the body. A comparison line works as a headline on the image. Put the quote in quotation marks and attribute it with a first name and initial or "verified buyer", with permission where your review app's terms require it.

  • Primary text: the doubt quote, then one line on why it is not a problem
  • Headline: the comparison or result, under ten words
  • Image or video: the product doing what the quote says

6. Trim without changing the meaning

You can cut words; you cannot add them. Use an ellipsis where you shorten, never join sentences from two different customers into one quote, and never tidy a line into something the customer did not say. Testimonials are your advertising, so a quote you altered is a claim you made. source, checked 28 September 2026

7. Check each line as if you had written it

Read every quote and ask: could the store say this in its own voice and prove it? If not, the ad cannot say it through a customer either. This matters most for health and skin products, where a customer writing "it cured my eczema" is a medical claim the moment you run it; the supplements industry page covers where that line sits.

On Meta, also check that the ad does not turn a customer's story into a statement about the viewer. "It finally calmed my skin" in quotation marks is a testimonial; "Your skin will finally calm down" is a claim about the person scrolling.

8. Write several versions per angle and test them

Group the finished lines into angles, one per doubt or result, and write three to five ads for each so the test compares angles rather than single lucky ads. The guide to testing ad creative covers how to run them without overspending.

A worked example

  • For a dog harness store with 640 written reviews

    Worked example (an invented store with invented numbers)

    The export has 640 written reviews. Filtering out the one-liners leaves 212 with something specific to say, and 9 of those are flagged as free-product reviews and set aside, leaving 203.

    Sorting sentences gives three strong clusters: 74 reviews mention the dog no longer pulling, 51 mention a good fit on a deep-chested breed, and 33 compare it with a harness that broke. The other 45 are too general to use.

    That makes 3 angles. The owner writes 3 ads for each, 9 ads in total, every one opening with a customer's own sentence, such as "I was sure it would rub under his legs. It doesn't."

Common mistakes

Picking the single most dramatic review. It is the one most likely to mislead, and the one a regulator or a sceptical reader will question first. Pick lines that many customers would recognise.

Paying for positive reviews to use in ads. The FTC says an incentive cannot depend on the review being good. Ask every customer for an honest review, then choose from what comes in. source, checked 28 September 2026

Polishing the quote until it sounds like your brand. Customers write "it just works", not "engineered for effortless performance". The rougher version is why the ad reads as real.

Forgetting the landing page. An ad that opens with a worry about sizing should land on a page that answers sizing near the top, or the reader who clicked for that answer leaves.

Tilly publishes ads to Meta paused and never turns spend on, and nothing goes out without your approval, so you can check every line against the typical-result and trimming rules above before a penny is spent.

Questions people ask

Do I need the customer's permission to quote their review in an ad?

Check your review app's terms and the platform the review was left on first; some limit reuse. Using a first name, photo or video in an ad is safest with written permission, and asking takes one email.

Can I use reviews from Amazon or another marketplace?

Those reviews sit under the marketplace's terms, not yours, so read them before you reuse anything. Reviews left on your own store are simpler to work with.

When did the FTC's reviews rule start to apply?

The FTC's rule on consumer reviews and testimonials took effect in October 2024. It targets fake and bought reviews, and courts can impose penalties for knowing violations. source, checked 28 September 2026
