Evaluate creative concepts against audience, channel, evidence, brand, accessibility, and testability. Provide: Campaign brief and criteria, Creative concepts, Audience and performance evidence. Expected result: A criterion-based creative comparison with risks, revisions, and a test-ready shortlist.

Your prompt

Compare the supplied creative concepts for fit; do not choose by personal taste.
Objective, audience, journey stage, offer facts, channel, CTA, constraints, and priorities:
[brief]
Concept IDs, messages, headlines, visuals, proof, formats, CTAs, variants, and rationales:
[concepts]
Research, prior results, prohibited claims, brand/legal/accessibility rules, production limits, and unknowns:
[evidence]
Preserve every concept ID and extract its literal promise, attention device, assumed audience belief, required proof, and intended behavior. Flag claims or visual implications that exceed supplied facts. Define evaluation criteria before applying them: audience/job relevance, message clarity, evidence fidelity, journey/channel fit, CTA continuity, distinctiveness within supplied context, accessibility, trust/ethics, production feasibility, localization, and testability only where relevant. Use supplied weights; if absent, do not invent a total score or winner.
For each concept provide evidence for and against fit, unknowns, failure modes, accessibility/brand/legal issues, production dependencies, and the smallest revision that preserves its core. Distinguish fatal constraint, fixable weakness, creative preference, and empirical uncertainty. Identify concepts too similar for a useful test and bundled differences that prevent interpretation. Produce a shortlist conditional on priorities, a rejected/deferred ledger, and a clean test matrix with one meaningful variable, primary behavior, guardrails, and interpretation limit.

From input to outcome
A worked example
See how concrete context turns this recipe into a usable result
Actual input
Campaign brief and criteria
Promote four free library digital-skills workshops to consenting local adults. Email subject and poster headline should help people decide relevance and register. Facts: free, 21-22 Sep, 48 total seats, English with Chinese interpretation, help using online public services. No guarantee of jobs, savings, confidence, or service outcomes. Priority order: evidence fidelity and accessibility; then relevance/clarity; then production within 5 design hours. No numerical weights.
Creative concepts
C1 'Master the digital world in one hour' with rocket visual; CTA Transform your future. C2 'Free digital-skills workshop: practical help with online public services' with date, language, and simple laptop illustration; CTA View sessions and register. C3 'Only 48 seats—don't get left behind' with countdown visual; CTA Claim your place. C4 'Need help with online forms?' with a cropped screenshot of a real government form; CTA See workshop details. C5 'Free workshop—48 seats' with calendar icon; CTA Register.
Audience and performance evidence
Audience interviews are not supplied. Last email test observed more page visits for a concrete topic/capacity subject but downstream registration effect is unknown. Brand prohibits fear/shame and transformational promises. Must work in English/Chinese, plain text, large print, and screen reader; no rights to government screenshot. Designer has 5 hours; bilingual reviewer 3. Registration page says view sessions before choosing.
Example output
C1 literal promise is broad mastery/transformation in one hour, unsupported and inconsistent with brand; rocket adds the same implication. Fatal without replacing its core, so reject. C2 accurately states format/topic, supports relevance, matches “view sessions and register,” and can use accessible owned illustration; strongest fit under stated priority. Risk: headline length in bilingual/subject contexts; fix by channel-specific shortening while retaining “online public services.” C3 uses truthful 48 seats but frames shame/fear and “claim” bypasses session review; brand conflict is fatal to current concept. Capacity may be retained neutrally.
C4 has a specific need-led question, but audience evidence for form difficulty is absent and the screenshot lacks rights/accessibility; fixable by replacing it with owned text/illustration and treating need resonance as a hypothesis. The workshop does cover online public services, so the question is within scope if not presented as a universal problem. C5 is feasible and evidence-faithful but omits topic/language, so people may click without knowing relevance; it is a capacity-led variant, empirically uncertain rather than bad.
Conditional shortlist: use C2 as the production baseline for maximum evidence/accessibility/clarity. Retain revised C4 for a later need-led test after owned visual and bilingual/plain-text review. Retain C5 only as a subject-line comparison if body/sender/time/CTA remain identical; prior evidence supports testing, not declaring it superior. Deferred ledger: C4 pending rights replacement/audience check; C5 pending clean test. Reject C1/C3 in current form for unsupported/brand claims.
Clean test: C2-short “Free digital-skills workshop: online public-service help” versus C5-expanded “Free digital-skills workshop—48 seats”; only emphasis topic versus capacity differs, though both should retain truthful basics in preview/body. Primary unique page visitors/delivered; guardrails unsubscribe/complaint/accessibility; registrations by arm unavailable. A result applies to this audience/campaign only and cannot prove motivation.
Why this works
1
Literal promise extraction catches overclaiming that can hide inside a visual metaphor or clever headline
2
Separating fixable weakness from empirical uncertainty avoids discarding a sound idea before a fair test
Check the result
Is every concept assessed against the same predeclared criteria and actual evidence
Are unsupported claims, implied promises, fatal constraints, and fixable weaknesses distinct
Does the shortlist and test isolate a decision-relevant creative difference

Frequently asked questions
Practical answers about when to use this recipe, what to provide, and where human review still matters
What should I prepare before using “Compare marketing creative concepts for fit”?
For “Compare marketing creative concepts for fit,” prepare Campaign brief and criteria, Creative concepts, and Audience and performance evidence.

Use the checks as release gates: revise the source inputs or assign a named, authorized reviewer instead of polishing an unsupported output.
