When to use a trade show marketing review methodology

Use the method at buying moments

Apply the methodology when building a tender shortlist, before making a new booking and at contract renewal. Repeat relevant checks if a supplier changes an important claim or following a compliance, delivery or attendee-data incident.

Before repeat bookings, refresh scores for that cycle; routine updating does not replace checks prompted by a specific change or incident.

The method changed in 2026 because supplier claims have become easier to publish and harder to verify. Since 2024, more exhibit suppliers have published self-scored performance pages. A written approach makes clear what is being assessed, what falls outside the review and whether each input comes from a named source with a date.

Set the review boundary first

The review boundary covers four areas: commercial terms, delivery capability, compliance record and reference quality. Each area is divided into criteria with written definitions, so two reviewers consulting the same supplier material can reach a consistent answer.

The boundary excludes stand design taste, staff friendliness during an event and any matter that requires attendance on site. Suppliers have not been tested at a live event as part of this review, so a score must not be read as evidence that a site visit happened.

Follow the evidence ladder

Independent evidence forms the first tier and includes regulator records, published standards, company filings and dated third-party research. Supplier brochures, case studies and self-reported metrics sit in the second tier.

Editorial judgement is the third input and must be labelled as judgement, not presented as independent proof. For a broader treatment, see trade show marketing reviews.

A supplier's own figures may look strong while independent support is absent. In that situation, the independent finding governs the assessment, and a claim only contributes to a score when a tier one source corroborates it. Where evidence does not reach the criterion, record it as not assessed rather than assigning a low score.

Check compliance records in context

Regulatory records belong in supplier due diligence, not in an optional final check. Non-broadcast advertising claims made by an exhibit supplier fall under the CAP Code.

The ASA rulings database can show whether a supplier or its agency has faced a published ruling, a useful signal when a pitch relies on performance promises. A disclosure policy can help keep stand claims on record.

Stand teams collect badge scans and enquiry data, so a supplier handling personal information should explain its lawful basis under the UK GDPR and its obligations under the Data Protection Act 2018. The ICO complaints and concerns data sets show issues reported to the regulator; check the ICO's published enforcement notices for formal outcomes. PECR may also apply to electronic marketing. See these data protection checks when considering the data involved.

BSI's BS ISO 20400:2017, Sustainable procurement: Guidance, can inform a supplier review by offering guidance on integrating sustainability into procurement. It is guidance, however, and does not prove that a stand builder is compliant. Keep that distinction visible in the record instead of treating a reference to the standard as a certificate or outcome.

Turn supported findings into scores

Use a four-point scale with written anchors so that the same score has the same meaning throughout the review. A criterion without evidence receives no score, which prevents an unsupported assumption from affecting the average. The four-point score belongs to supported findings, not to gaps in the available record.

Reviewers should log each source and its retrieval date. If a supplier changes a page, record the change rather than silently altering an earlier result. Use the selection checklist to identify documents to request before scoring starts, then keep the evidence and score connected in the review record.

The table is an illustrative example, not a set of measured results. It shows why a claim can remain visible without being treated as proof, and how additional dated material can make assessment possible. If evidence is still missing, the supplier is not penalised, but the unassessed gap remains clear to the reader.

Keep judgement separate from proof

Editorial judgement can address fit, including whether a supplier's stated specialism appears suited to the buyer's event type and budget band.

Record that view separately from the evidence so readers can weigh it for themselves. A supplier comparison can help frame the fit question without turning opinion into a verified fact.

Judgement cannot replace a missing document. If a supplier says it holds a certificate but does not provide it, leave that criterion unscored, regardless of how persuasive the pitch sounds. The distinction keeps the method useful at selection and renewal while avoiding claims that the available material cannot support.
