The short answer
- Misleading advertising is any ad that leaves a reasonable buyer believing something untrue or unproven, even if every sentence is technically true.
- Documented cases include Skechers toning shoes ($40M FTC settlement), Volkswagen "clean diesel", Dannon's Activia, Lumosity and UK ASA bans of retouched beauty ads.
- The common failure is a claim with no proof behind it, or an image that shows a result the product cannot deliver.
- The fix is simple: hold proof for every checkable claim before the ad runs.
What makes an ad misleading
Misleading advertising is any ad that leaves a reasonable buyer believing something that is not true, or that you cannot prove. The ad does not have to contain a lie. A true sentence can mislead through what it leaves out, a picture can mislead without a word, and a number can mislead by hiding what it was measured against.
Regulators such as the US Federal Trade Commission (FTC) and the UK Advertising Standards Authority (ASA) judge the net impression an ad creates, not the fine print. The cases below are documented, public, and each one shows a different way an ad goes wrong.
| Type | What the ad does | Case in this post |
|---|---|---|
| Claim with no proof | States a benefit that no study supports | Skechers, Dannon, Lumosity |
| False product claim | Says the product is something it is not | Volkswagen "clean diesel" |
| Edited visual | Image shows a result the product cannot deliver | UK ASA retouched beauty ads |
| Puffery taken literally | Slogan read as a factual performance claim | Red Bull |
Skechers: toning shoes that promised weight loss
In May 2012 Skechers agreed to pay $40 million to settle FTC charges over ads for its Shape-ups and other "toning" shoes. The FTC said Skechers made unsupported claims that the shoes would help people lose weight and tone their muscles, and that it falsely implied clinical studies backed those claims. The FTC said the money went to refunds for consumers who filed claims, and in 2013 an administrator mailed 509,175 checks.
What made it misleading. The ads promised a physical result and borrowed the authority of science to sell it. The shoes did not need to be bad for the ad to fail. The ad failed because the claim had no evidence behind it.
What to do instead. Describe what the product is and what you can show. "Rocker sole for a different walking feel" is a product fact. "Burn more calories with every step" is a result that needs proof you hold before the ad runs.
Volkswagen: the "clean diesel" campaign
The FTC charged Volkswagen with deceiving consumers through an ad campaign promoting "clean diesel" VW and Audi cars as low-emission and compliant with emissions standards. A court-approved FTC order in 2016 made up to about $10 billion available to owners of 2.0-liter diesels for buybacks, lease terminations and fixes. In a 2020 summary the FTC reported that Volkswagen and Porsche had repaid more than $9.5 billion to car buyers. The broader $14.7 billion US settlement also covered emissions cheating and pollution mitigation, handled by other agencies.
What made it misleading. The cars used software that behaved differently during emissions tests. Every ad that said "clean" repeated a claim the company knew to be wrong.
What to do instead. Environmental and performance claims are only as good as the product behind them. If a claim depends on a test, the product must pass the test in real conditions, not only in the lab.
Dannon: probiotic yogurt and the cold and flu claim
In December 2010 Dannon agreed to drop exaggerated health claims for Activia yogurt and the DanActive drink and to pay $21 million to 39 state attorneys general working with the FTC. The FTC said the claim that Activia was clinically proven to regulate digestion was false, and that DanActive ads suggested the drink reduced the likelihood of colds and flu without the science to say so. The final FTC order was approved in February 2011.
What made it misleading. "Clinically proven" is a specific factual promise. Using it without a study that proves the exact claim turns a marketing phrase into a false statement.
What to do instead. Keep "clinically proven", "doctor recommended" and "scientifically tested" for claims where you can hand over the study, in the form the ad describes.
Lumosity: brain training and age-related decline
In January 2016 Lumos Labs, the maker of Lumosity, settled FTC charges over ads claiming its games could improve performance at work and school and reduce or delay age-related cognitive decline. The FTC said the claims were unfounded. It also said the company failed to disclose that some testimonials came from contests that offered prizes. A $50 million judgment was suspended because of the company's finances once it paid $2 million.
What made it misleading. Two things. The claims outran the science, and the testimonials looked like spontaneous praise when they had been prompted by prizes.
What to do instead. A review you incentivised is not a neutral review. Say so, or do not use it as proof. Our guide to ad copy examples shows how to write specific, true proof lines instead.
The UK ASA and retouched beauty ads
The ASA has repeatedly banned beauty ads where post-production exaggerated what a product could do. Its guidance says advertisers should not use digital retouching to exaggerate the effect a product can achieve. Ads featuring Julia Roberts for a Lancome foundation were among those banned, and in 2007 the ASA published rulings against L'Oreal and Rimmel for mascara ads that exaggerated lash effects, after which beauty advertisers had to state when false lashes were used.
What made it misleading. The photograph was the claim. If the image shows skin or lashes the product cannot produce, the picture is a false promise even with no text.
What to do instead. Use unretouched before and after shots of real results, or keep retouching to colour and lighting and out of the area the product is meant to change. For layout ideas, see the before and after ads guide.
Red Bull: when a slogan is read literally
In 2014 Red Bull agreed to a roughly $13 million settlement of class actions in New York federal court that argued "gives you wings" was misleading because the drink offered no edge over coffee. Eligible buyers could take $10 in cash or product worth about $15. Red Bull did not admit wrongdoing and said its marketing was truthful. This was a private lawsuit, not a regulator action.
What it teaches. Playful exaggeration is usually safe when no reasonable person takes it literally. It gets risky when the slogan sits next to a performance promise. Keep the joke in the headline and keep any measurable benefit in plain, provable words.
Five patterns behind most misleading ads
- Proof implied, not held. "Clinically proven", "tests show", "experts agree" with no study in a drawer.
- Result without a baseline. "Up to 70% off" where one item is 70% off. "2x faster" with no comparison named.
- Price that changes after the click. Headline price excludes fees the buyer meets at checkout.
- Urgency that is not real. A countdown timer that resets, "only 3 left" on unlimited stock.
- Reviews and endorsements with a catch. Paid, prompted or cherry-picked, shown as typical.
Most of these show up in the hook, the first line of the ad. Our notes on ad hook styles cover how to write a strong opening that stays true.
A pre-publish check for your own ads
- Highlight every claim in the ad that a customer could check: numbers, comparisons, outcomes, "best", "only", "first".
- Next to each one, write where the proof lives. If you cannot name it, cut or soften the claim.
- Read the ad as a stranger who sees only the image and the first line. What would they think they are getting?
- Match the landing page. Same price, same offer, same product as the ad shows.
- Check that any testimonial is real, current and typical. If it is not typical, show the typical result.
- Keep a folder of the proof for each live ad, so a platform or regulator query takes minutes, not weeks.

Frequently asked questions
What is an example of misleading advertising?
The FTC case against Skechers is a clear one. Ads for Shape-ups toning shoes claimed they would help people lose weight and tone muscles without evidence, and Skechers paid $40 million to settle the charges in 2012.
What is the difference between false and deceptive advertising?
False advertising states something untrue. Deceptive advertising can use true statements but still leaves buyers with a wrong impression, through omission, framing or imagery. Regulators judge the overall impression an ad creates.
What is an example of unfair advertising?
An ad that causes real harm buyers cannot reasonably avoid. The Volkswagen "clean diesel" case is often cited, because buyers had no way to learn the cars behaved differently outside emissions tests. The FTC treated that campaign as deceptive.
Can an ad be misleading if every word is true?
Yes. Leaving out a fee, showing a retouched result or choosing an unrepresentative testimonial can mislead even when each sentence is accurate. The ASA bans retouched beauty ads for this reason.
Is advertising puffery illegal?
Obvious exaggeration that no reasonable person takes literally, such as "world's best coffee", is generally treated as puffery. It becomes a problem when it implies a measurable fact you cannot prove, like a performance benefit.
How do I avoid making a misleading ad?
Hold proof for every checkable claim, match the ad to the landing page, label incentivised reviews, and avoid images that show results the product cannot deliver. Keep a proof file for each live ad.
