What claims can a small business make in an ad?

In the US and the UK the core rule is the same: you must be able to prove what your ad says, or implies, before it runs. The FTC asks for a reasonable basis, and scientific evidence for health and safety claims; the UK CAP Code asks for documentary evidence first. Fake reviews are banned in both. Obvious puffery is fine; specific numbers need proof.

United States: the FTC basics

The FTC's guide for small business sets out three rules: ads must be truthful and not deceptive, advertisers must have evidence to back up their claims, and ads cannot be unfair. It looks at the whole ad as a reasonable consumer would, including implied claims: "kills the germs that cause colds" implies "prevents colds", and you need proof for that. Proof must exist before the ad runs. Health and safety claims need competent and reliable scientific evidence, and letters from satisfied customers do not count as proof. Ad agencies can be held responsible too.

Since 21 October 2024, the FTC's rule on consumer reviews and testimonials targets fake or false reviews and testimonials, with civil penalties for knowing violations.

United Kingdom: the CAP Code basics

The ASA enforces the CAP Code. Its misleading advertising section says ads must not materially mislead (rule 3.1), must not leave out material information (3.3), and that marketers must hold documentary evidence for objective claims before publishing (3.7). Obvious exaggeration that no one takes literally is allowed (3.2). Unqualified superlatives are treated as comparisons against every competitor and need evidence unless they are clear puffery. Fake consumer reviews are banned (3.44), incentivised reviews must be flagged (3.45), and you need proof a testimonial is genuine (3.47).

Platform rules sit on top

The platforms add their own layer. TikTok's ad policy (April 2026) bans promising or exaggerating results, absolute claims about time, region or brand, before-and-after result comparisons, and any mismatch between the ad and the landing page on price, discount or promotion. Its own example: an ad saying "up to 50% off" while the site says "up to 30% off" is not allowed.

A sung claim is still a claim

Music makes words feel lighter, not legally lighter. "The softest towel you'll ever own" in a chorus is a superlative claim. "Clears skin in a week" sung sweetly is a health and result claim. Before you approve lyrics, read them as if they were printed in the caption. SingingAds copies every claim from words on your page and flags health, money, result and comparison claims for you to check; see claims from your page.

A five-minute pre-flight check

  1. Underline every factual claim, spoken, sung or on screen.
  2. Next to each, write where the proof is (a test, a spec sheet, a supplier certificate).
  3. Check that prices and offers match the landing page exactly.
  4. Delete any review or quote you cannot trace to a real customer.
  5. Ask: what would a reasonable buyer assume from this that I have not said?

This is general information, not legal advice. For regulated products, ask a lawyer. Related reading: AI label rules and how SingingAds builds a brief.

Illustrative example: auditing a product page before writing lyrics

Product: Saltmarsh Skin Balm (fictional). Lines on its page and what can be sung:

  • "Made with shea butter and beeswax": a fact about ingredients. Fine to sing.
  • "50 ml tin, ships in two days": a checkable fact. Fine, if true at the time of the ad.
  • "Heals eczema": a health claim needing scientific evidence. Leave it out.
  • "Britain's favourite balm": an unqualified superlative. Leave it out or replace it with something you can show.
  • "Loved by 10,000 customers": a number you must be able to prove. Leave it out unless you can.

Sung line that survives: "Shea and beeswax, tin in your bag, Saltmarsh."

Questions

Can I call my product the greatest or the softest?

Vague puffery like "great taste" is usually fine. Specific superlatives ("the softest", "the top-selling") need evidence in the UK and can break TikTok's absolute-claims rule.

Do customer reviews count as proof for a claim?

Not for objective claims. The FTC says letters from satisfied customers are not enough to support a health or safety claim.

Does the FTC check ads before they run?

No. The FTC says its staff cannot clear ads in advance; it is up to you to have proof before launch.

Can I use an AI-generated customer quote?

Not as if it were real. A made-up testimonial presented as genuine is a fake review under both US and UK rules.

Is my ad agency responsible too?

It can be. The FTC says agencies may be liable for misleading claims and must check the substantiation themselves.
