Web design agency advertising: small print and claim checks for buyers

When shortlisting a web design agency, treat its advertising as a set of statements to test, not a substitute for a project brief. Separate the advertised service, the qualifications attached to it and the evidence behind any claimed result. Record what needs clarification before carrying a promise into your purchasing decision.

Key takeaways for agency advertising

Treat an agency's advertised service, its qualifications and its supporting evidence as separate checks. Read the exact promise before judging the presentation. Ask whether significant limitations change your understanding of the offer, and keep unresolved claims out of the agreed project scope until they have been clarified.

Use a selection checklist to keep this review connected to your shortlist. Copy the claim into your notes without improving or softening it. Keep the surrounding wording with it, including any qualification. Ask the agency to clarify an unresolved promise before treating it as an agreed feature of the commission.

Keep significant qualifications with the claim

CAP advice on small print and footnotes says marketing communications must not mislead by omitting significant limitations and qualifications that apply to the advertised product or service. For a buyer, start by reading the advertised promise and its qualifications together before deciding what the offer means.

For a website commission, ask about the boundaries of each advertised service. Consider page design, copywriting, hosting, launch assistance and ongoing maintenance as separate questions. Do not assume that a broad service label answers them all. Request wording that makes the intended scope clear rather than filling the gaps with your own expectations.

Screen the wording, not the impression

Use the following illustrative wording as prompts, not as claims about any actual agency. Each row identifies a question to resolve before relying on the statement. The aim is to turn an attractive phrase into a specific proposition that the agency can explain and support.

For results claims, use web agency case studies as a separate evidence check. Ask for the measurement definition, comparison period and boundaries of the claim. Avoid rewriting an observed change as proof that the agency caused it. Keep unresolved questions attached to the claim during shortlisting.

For testimonials and client references, request enough context to understand what is being endorsed. Compare the quoted wording with the service you are considering, rather than assuming that every endorsement covers every service. A disclosure policy can help you frame questions about authorship, testing and client ties during the review.

Worked example: narrow a support promise

Consider an illustrative agency listing that advertises website design with ongoing support. Suppose the intended service includes support for the launch handover only, with ongoing maintenance excluded. The buyer's task is to compare the headline promise with that intended boundary, then request wording that reflects the offer.

The revised wording removes the broader support promise and expresses the exclusion directly. Treat this as an example of narrowing copy, not a legal verdict. Ask the agency to confirm the same scope in its proposal, then use commercial contracts to frame questions about delivery responsibilities and approval of the agreed wording.

In a separate illustrative example, the draft claim is "More enquiries after redesign", but the reviewer has no evidence supporting the claimed change or its cause. The review decision is to hold that wording. Ask for the measurement record before approving a results claim, rather than inventing a percentage or assuming causation.

Know the named consumer-law context

Under the Digital Markets, Competition and Consumers Act 2024, the CMA can directly enforce some consumer laws and, as well as a court, decide whether a business has broken the law, as described in its direct consumer enforcement guidance on the use of those powers.

The CMA is the UK's main competition and consumer enforcement body. "Unfair commercial practices" is a separate guidance document, reference CMA207. Keep a note of the document relevant to each consumer-law question, rather than treating every advertising concern as the same issue.

A penalty can be up to 10% of a business's global turnover or £300,000, whichever is greater. Preserve "up to" and "whichever is greater" when repeating that ceiling. Do not turn it into a prediction about a particular agency or infer a legal outcome from an unresolved advertising claim.

Questions before approving an agency brief

What should go into the brief?

Once a claim has been clarified, put the agreed meaning into your web design brief. Keep the original wording, the explanation and your decision together. Distinguish what the agency has confirmed from what you have merely inferred, so an attractive listing does not become an unsupported requirement in the commission.

What should be checked before approval?

Use a claim record to separate a question from a decision. For each promise, retain the wording you assessed and the explanation you received. Review the scope and evidence together before accepting a claim for the buying decision. Leave an unresolved item visibly open rather than treating silence as confirmation.

What if the wording changes?

Put remaining agency questions to the shortlisted provider before approving the brief. Record whether each claim is accepted for the buying decision, needs revision or remains unresolved. Recheck the record if the wording or proposed scope changes. Keep this practical review separate from any legal assessment of the advertising.
