Executive summary

Marketing claims often outlive the evidence that supported them. A staff member may reuse an old award badge, quote a certification that has expired, or repeat a performance claim from a proposal without knowing its conditions. A marketing evidence folder gives the team a traceable source for claims that customers may rely on.

This is a documentation workflow, not legal advice. Allow 45–60 minutes to inventory claims on one website or campaign family, then schedule a review based on the evidence’s expiry and change risk.

Decide which claims need evidence records

Prioritise claims that are specific, measurable, comparative, time-sensitive or likely to influence a purchase. Examples include certifications, awards, years of experience, service guarantees, “number one” statements, performance outcomes, customer statistics and claims about the materials or methods used.

Ordinary descriptive wording may need less formal documentation, but the business should still be able to explain what it means. A statement such as “fast response” becomes more consequential if it is presented as a specific response-time commitment.

Do not assume that a claim is safe merely because it has appeared on the website for years. Reuse does not renew the evidence.

Create a claim register

Use one row per claim:

claim_id | exact wording | where used | evidence link | evidence owner | scope/conditions | approval date | expiry/review date | permitted wording | status

Store the underlying evidence in a business-controlled folder and link to it. The register should make it easy for a writer to find the approved phrasing without copying a claim from an old image.

For a credential, record the issuing body, scope, holder, status and expiry date where applicable. For an award, record the awarding organisation, category, year and any limits on how the award may be described. For a performance statistic, record the measurement period, denominator, method and exclusions.

Separate evidence from interpretation

A source document may support a narrow statement but not a broader marketing claim. For example, a survey of a small set of customers does not automatically support “all customers prefer us.” A certificate for one service does not prove that every service the business offers is certified. An award received in one year should not be presented as a current annual distinction.

Write the strongest wording the evidence actually supports, not the strongest wording the team wishes were true. If a claim requires context to remain accurate, keep that context with the approved phrase so it is not lost during design or translation.

Add expiry and change triggers

Some evidence has a printed expiry date; other evidence becomes stale when the business, product, service or measurement method changes. Set a review date for both. A staff qualification may need checking after a role change, while a customer statistic may need a new measurement period.

Use statuses such as approved, approved with qualification, expired, unsupported and under review. Only approved claims should be available for new creative. Move expired evidence out of the active folder but retain it according to the business’s recordkeeping policy.

Build the check into content production

When a brief includes a factual claim, the producer links the claim ID rather than inventing a fresh wording. The reviewer confirms that the evidence is current and that the final asset has not broadened the claim. A translator or designer should be told which conditions must remain visible.

If the wording changes during approval, recheck whether the evidence still supports it. A small wording change can alter meaning—for example, turning “selected customers reported” into “customers achieve.” The evidence owner should approve material changes to the claim, not just the visual design.

Handle missing or disputed evidence

If the team cannot locate support, mark the claim unsupported and remove it from new content until it is verified. Do not treat a verbal recollection as equivalent to an official certificate or a documented measurement. If evidence is disputed, escalate it to the person responsible for the underlying facts.

For a public page already using an unsupported claim, assess the likely customer impact and correct it promptly. Record where else the wording appears so the same statement is not left in a PDF, pinned post or saved reply.

Make the folder easy to use

Organise records by claim type or claim ID rather than by the employee who originally created them. Use descriptive filenames, restrict edit access where necessary and keep a backup under the business’s normal document policy. Avoid storing personal information that is not needed to substantiate the claim.

A folder full of certificates is not enough if nobody knows which sentence each document supports. The claim register is the index that connects evidence to permitted wording and live placements.

Conclusion and next steps

Start with the claims that could most seriously mislead a customer if wrong. Link each to evidence, define its permitted wording, and set a review or expiry date. This creates a repeatable check that helps prevent unsupported claims from being copied into future marketing materials.
