Express Claims, Implied Claims, and How an Ad's Meaning Gets Decided

An advertiser is answerable for what an advertisement says and for what it suggests. The test is not what the marketer meant. It is what the whole page conveys to a reasonable member of the audience it was aimed at.

Key takeaways

  • Identifying what an advertisement claimed is a separate step that comes before asking what supports it, and the FTC guidance describes the process in that order.
  • Responsibility runs to implied claims as much as express ones: a marketer may not suggest indirectly what it could not claim directly.
  • Meaning is assessed as a net impression across text, product name, images, charts and graphs — the entire mosaic, rather than each tile separately.
  • Where a page carries more than one reasonable reading, the advertiser is responsible for substantiating each of them.
  • The intended audience is part of the test, and the guidance names terminally ill consumers as an example of a group judged by its own reasonable member.
  • Omissions are claims too: material limitations on a benefit, and significant safety risks in customary use, are things the guidance says should be disclosed.

Answer first: the meaning is set by the reader, not by the writer

Before anyone can ask whether an advertisement is supported, somebody has to decide what the advertisement actually claimed. The Federal Trade Commission's health-products guidance describes this as the first of a two-step process: identify all the claims the materials communicate to reasonable consumers, then assess the evidence behind those claims.

The guidance is blunt about whose reading counts. Under FTC law, a marketer is equally responsible for the accuracy of claims suggested or reasonably implied in advertising. Marketers cannot suggest benefits, safety, or other characteristics about their product indirectly that they could not claim directly.

And it states the perspective explicitly: FTC law focuses not on the marketer's intent, but on the consumer's understanding. The determination of what claims are made is consumer-driven — what reasonable consumers understand the materials to communicate about the product.

That single sentence relocates the whole question. A marketer who never typed a sentence promising a result can still have made the promise, if the assembled page communicates it.

The net impression rule, and what it sweeps in

The guidance tells marketers not to focus narrowly on individual phrases or statements, but to consider each advertisement as a whole, assessing the net impression conveyed by all elements of the advertisement, including the text, the product name, and any charts, graphs, and other images.

The older deception policy statement says the same thing in an older idiom. In advertising, the Commission will examine the entire mosaic, rather than each tile separately. It quotes a court of appeals describing the principle: the Commission's right to scrutinise the visual and aural imagery of advertisements follows from the principle that the Commission looks to the impression made by the advertisements as a whole; without this mode of examination, the Commission would have limited recourse against crafty advertisers whose deceptive messages were conveyed by means other than, or in addition to, spoken words.

The worked examples in the health guidance show how wide that is. A brochure for a weight-loss product showing doctors in white lab coats looking through microscopes, molecular structures and a stack of medical journals gives an impression of scientific legitimacy and, the guidance says, likely conveys an implied claim that the product has been clinically proven to be effective for weight loss. Not one word of that claim appears in the text.

Another example runs on a chart. An infant formula advertisement includes an unrelated graph from a pediatric journal showing that colicky babies generally cry less over the first twelve weeks of life. The graph has nothing to do with the formula. Using it in the advertisement, the guidance says, likely implies that the formula, rather than the babies' ages, causes the decrease in crying time.

A third runs on the product's own name. A supplement called Cold Away, advertised as boosting the immune system to help maintain a healthy nose and throat during the winter season, with images of people sneezing and coughing, likely conveys that the product helps prevent colds — and the guidance adds that even without the name and the images, the winter-season reference alone likely conveys the prevention claim.

More than one reasonable reading, and the advertiser owns all of them

This is the rule that surprises people. The health guidance states it plainly: when an advertisement lends itself to more than one reasonable interpretation, the advertiser is responsible for substantiating each interpretation.

The deception policy statement gives the same rule its longer form. To be considered reasonable, the interpretation or reaction does not have to be the only one. When a seller's representation conveys more than one meaning to reasonable consumers, one of which is false, the seller is liable for the misleading interpretation. And an interpretation will be presumed reasonable if it is the one the respondent intended to convey.

There is a boundary on the other side, and the policy statement quotes it at length rather than paraphrasing. An advertiser cannot be charged with liability with respect to every conceivable misconception, however outlandish, to which his representations might be subject among the foolish or feeble-minded. A representation does not become false and deceptive merely because it will be unreasonably misunderstood by an insignificant and unrepresentative segment of the class of persons to whom the representation is addressed.

So the standard is not the most gullible imaginable reader, and it is not the most careful one either. It is a reasonable member of the group the advertisement was aimed at.

The audience is part of the test

Both documents make the intended audience an input rather than a background fact. The health guidance says the Commission views advertising claims from the standpoint of the intended audience, and offers a pointed illustration: terminally ill consumers might be particularly susceptible to exaggerated cure claims.

The deception policy statement builds that out in both directions. When representations or sales practices are targeted to a specific audience, such as children, the elderly, or the terminally ill, the Commission determines the effect of the practice on a reasonable member of that group. By the same token, a practice or representation directed to a well-educated group, such as a prescription drug advertisement to doctors, would be judged in light of the knowledge and sophistication of that group.

For material aimed at people who are already looking for a weight or metabolic treatment, that matters. The audience is self-selected and motivated, and the reasonable member of it is not a disinterested browser. The same page can therefore carry a claim to that audience which it would not carry to a general one.

How the meaning gets established in a contested case is a separate question. The guidance says extrinsic evidence such as consumer surveys and copy tests can be valuable in determining how consumers interpret certain implied claims. In many cases, however, it says the claims conveyed are clear enough on the face of an advertisement, without the need for extrinsic evidence.

Omissions count, and structure-or-function wording is not a safe harbor

An advertisement can also be deceptive because of what it leaves out. The health guidance points to Section 15 of the FTC Act, under which an advertisement is misleading if it fails to disclose information that is material in light of the claims in the advertisement or with respect to how consumers would customarily use the product. If the advertisement would be misleading without certain key qualifying information, that information must be disclosed.

The guidance lists the obvious cases. Advertisers should disclose any significant limitations on an advertised health benefit. Advertising that makes an express or implied safety representation should include information about any significant safety risks. And even absent affirmative safety representations, advertisers may need to inform consumers of significant safety concerns related to the customary use of a product.

One example is close to home for any results claim built on a trial. A weight-loss supplement marketer cites a placebo-controlled double-blind study showing an average loss over eight weeks, and the treatment group did lose significantly more than the controls. But both groups exercised regularly and followed a restricted-calorie diet as part of the study regimen. The guidance says the advertisement should make clear that users will also need to reduce calories and exercise to achieve similar results.

The guidance also closes a route people assume is open. Depending on how it is phrased or the context in which it is presented, a statement about a product's effect on the normal structure or function of the body may also convey an implied claim that the product is beneficial for the treatment of a disease. If elements of an advertisement imply a disease benefit, the advertiser must be able to substantiate the implied disease claim even if the advertisement contains no express reference to a disease.

The guidance's own summing-up is a two-item list. Consider what express and implied messages consumers are likely to take from your advertisements, and where appropriate carefully qualify your claims. Then review the support for each claim to make sure it is scientifically sound, adequate in the context of the surrounding body of evidence, and relevant to the specific product and advertising claim.

How to read a page with this in hand

The practical use of all this is to stop reading a sales page as a list of sentences and start reading it the way the rule reads it: as one impression assembled out of every element on the screen.

The elements the documents name are worth listing, because they are the ones people discount. The product's name. The photographs, including who is wearing a lab coat and who is holding a chart. Any graph, including graphs that are accurate about something other than the product. The surrounding text, including a reference to a season, a symptom, or a condition. And what is missing, including a study's diet and exercise conditions.

None of this establishes that any particular page is deceptive. That is a determination for a regulator or a court on a full record, and nothing here predicts one. What it does establish is the question a reader can ask for themselves: if I describe out loud what this page just told me, is that sentence anywhere in the text — and if it is not, is it a sentence the seller could have written directly and supported?

Frequently asked questions

What is the difference between an express and an implied claim?

An express claim is stated. An implied claim is suggested or reasonably conveyed by the material without being stated. The FTC's health-products guidance says a marketer is equally responsible for the accuracy of claims suggested or reasonably implied in advertising, and that marketers cannot suggest benefits, safety, or other characteristics indirectly that they could not claim directly.

Does it matter what the advertiser intended to say?

The guidance says FTC law focuses not on the marketer's intent, but on the consumer's understanding, and that the determination of what claims are made is consumer-driven. The deception policy statement adds one wrinkle in the other direction: an interpretation will be presumed reasonable if it is the one the advertiser intended to convey.

Can an image or a product name make a claim?

The guidance's examples say yes. It describes lab-coat imagery, microscopes and journal stacks as likely conveying an implied claim that a weight-loss product has been clinically proven, and it describes a product name together with images of cold sufferers as likely conveying a cold-prevention claim. It instructs marketers to assess the net impression conveyed by all elements, including the text, the product name, and any charts, graphs and other images.

If a page can be read two ways, which reading governs?

Both. The guidance states that when an advertisement lends itself to more than one reasonable interpretation, the advertiser is responsible for substantiating each interpretation. The deception policy statement puts it as a liability rule: when a representation conveys more than one meaning to reasonable consumers, one of which is false, the seller is liable for the misleading interpretation.

Is the standard the most easily misled reader?

No. The deception policy statement quotes the limiting principle directly: an advertiser cannot be charged with liability for every conceivable misconception, however outlandish, and a representation does not become false and deceptive merely because it will be unreasonably misunderstood by an insignificant and unrepresentative segment of the audience. The measure is a reasonable member of the group the material was aimed at.

Does saying a product affects a structure or function of the body avoid a disease claim?

Not by itself. The guidance says that depending on phrasing and context, a structure-or-function statement may also convey an implied claim that the product is beneficial for treating a disease, and that where elements of the advertisement imply a disease benefit the advertiser must be able to substantiate the implied disease claim even with no express reference to a disease.
