Turning one customer review into an ad

Why does one review beat a star rating?

A star rating is a summary, and summaries are easy to ignore. A sentence from a real customer is a story, and stories are specific: the burn time, the gift box, the second order. Specific details are what make a claim believable, because they are hard to invent.

The best review ads read like overheard conversation. "I bought one to try. I have now bought four" says more about quality than any adjective the brand could choose, because the customer did the persuading with their wallet.

There is a practical reason too. A single quote set large is readable at a glance in a feed, while a block of stars and small print needs the viewer to stop and study it, which most will not.

How do you choose and design the review?

Read your reviews looking for three things: a specific detail, a change of mind and a repeat purchase. Reviews that mention a feature, admit doubt and then report the result do the most work.

Set the quote as the headline, in quotation marks, with the customer's first name. Keep the product visible: in this ad the candle is too small, so the eye reads the words but cannot picture what to buy. Half the image for the quote and half for the product is a better split.

Match the background to the brand's packaging or site, so the ad looks like the shop rather than a template. If you want us to pull the strongest quotes from your own reviews, our free ad review starts there.

What are the rules for using reviews in UK ads?

Reviews must be genuine. The CMA's guidance on fake reviews explains that writing, commissioning or publishing fake consumer reviews is banned, and that a review given in return for an incentive must be clearly labelled as such.

The ASA's guidance on testimonials adds that advertisers need evidence the testimonial is real, permission to use it, and that a testimonial is not proof on its own of any objective claim it makes. If a customer says the candle "burns for 60 hours", you need your own evidence for that figure.

Asking customers for reviews is fine as long as you do not dictate what they say. Picking a positive review to feature is normal; editing it so it says something the customer did not mean is not.

How should you test a review ad?

Test the quote, not the design. Run the same layout with three different reviews: one about quality, one about gifting and one about value. The winning quote tells you what customers actually buy the product for, which is useful far beyond the ad.

Then test where it sits. Review ads often work best for people who already know the brand, so try them for visitors who have seen the site but not bought.

Finally, refresh the quote as the season changes. A gifting quote before December does a different job from a quality quote in spring. That weekly refresh is what our how it works process is designed for.

How do you turn reviews into a steady stream of ads?

Treat reviews as a content source, not a badge. Each month, export new reviews and tag them by theme: quality, gifting, value, service. Each theme becomes a family of ads you can rotate.

Keep a simple record for every quote you use: the original review, where it was published, the date, the customer's permission and the exact wording in the ad. That record answers any question about the quote later.

And close the loop with the customer. Thanking them and showing them the ad builds goodwill, and some will happily become the face of a short video version of their own review.

How does this work for other kinds of business?

Any business with happy customers can run this ad. A service business can quote a client on the experience ("they arrived when they said they would"), a software company can quote a user on the time saved, and a local shop can quote a regular on why they keep coming back.

The principle is the same in every case: choose the review that names a detail only a real customer would mention, and let it speak in their words. Specific beats general, and plain beats polished.
