A useful campaign brief is the control document between strategy and launch. It defines the decision, audience, promise, evidence, AI and brand boundaries, approved URLs, localization requirements, conversion event and the named human who can approve the final campaign. If a claim has no evidence owner or the campaign has no final approver, it is not ready to launch.
1. Business problem and decision
- What business condition must change?
- Why does it matter now?
- What is in scope and out of scope?
- Who owns the commercial result?
- What decision will the campaign evidence support?
- What budget, margin or capacity constraint shapes the plan?
Make the commercial decision clear before selecting tactics. For a paid campaign, use the Ad Budget Calculator to test whether the revenue target, close rate, customer value and media requirement fit together. If the work needs planning and execution support, review Maqtrix advertising campaign services.
2. Audience and buying situation
Describe the people involved, their trigger, current belief, alternatives, barriers and evidence needs. Include the buying group when more than one person influences the decision. Avoid persona details that do not change the work.
| Field | Write here |
|---|---|
| Primary audience | The people whose decision or behaviour must change |
| Buying trigger | The event, pressure or opportunity creating demand now |
| Current belief | What the audience believes before seeing the campaign |
| Barrier | The doubt, risk, habit or alternative blocking action |
| Evidence need | The information required to make the next decision confidently |
| Buying group | Other people who influence, approve, use or block the purchase |
3. Communication job
Complete one sentence: After seeing this campaign, [audience] should [think, feel or do] because they understand [single most important idea]. If the sentence contains several outcomes, the campaign probably needs prioritization.
Write the desired customer action separately. “Learn more” is often too vague. Name the real next step: calculate a budget, book a consultation, request an estimate, compare options, start an application or return to an unfinished decision.
4. Promise, claim evidence and mandatory facts
Write the promise in the language the audience will see, then connect every material claim to evidence, an accountable owner and a review date. In Canada, a product performance claim must be supported by an adequate and proper test completed before the claim is made. The Competition Bureau also considers the overall impression created by the words, images, design and context, not only whether each sentence is literally true. Its guidance says these requirements can apply to website copy, social content, metadata and online ads. [5] [6] [8]
| Field | Required entry | Owner or status |
|---|---|---|
| Core promise | The meaningful, defensible change being offered | Campaign lead |
| Exact public claim | The precise wording or visual implication the audience may see | Copy or creative owner |
| Claim type | Performance, comparative, price, savings, testimonial, guarantee, environmental or other | Compliance reviewer |
| Claim evidence | Test, source data, approved product fact, authorized testimonial or other supporting record | Evidence owner |
| Evidence owner | Named person accountable for the source, accuracy and permitted use | Name and role |
| Evidence scope | Product, audience, geography, period, conditions and limitations covered by the evidence | Evidence owner |
| Evidence record | Link, file name, version, test date and access location | Campaign operations |
| Required qualifier or disclosure | Wording, placement and format required to keep the message accurate | Compliance reviewer |
| Review or expiry date | When the evidence, offer or claim must be checked again | Evidence owner |
| Prohibited or restricted language | Unapproved guarantees, superlatives, savings claims, comparisons, urgency or other restricted concepts | Brand or compliance owner |
| Mandatory facts | Price, eligibility, service area, timing, terms, licensing or other required information | Business owner |
| Approval status | Approved, revise, rejected or expired | Final human approver |
The Maqtrix claim chain: Claim → evidence owner → source record → scope → disclosure → review date → human approval. A persuasive sentence is not launch-ready until the full chain is complete.
A footnote or disclaimer cannot reliably repair an advertisement whose main message creates a materially false or misleading overall impression. Broad evidence should not be inferred from a narrow test, a different product, an anecdote or a one-time result. This template is operational guidance, not legal advice. [5] [6]
5. Creative, brand and AI controls
Define the organizing idea first, then record the boundaries that every person, agency and generative system must follow. This matters because automated ad systems can create new assets from existing ads, website copy, landing pages and other account assets. Google AI Max offers messaging, brand and URL controls, but those settings do not replace human review. [1] [2]
| Control | Write here |
|---|---|
| Organizing idea | The single campaign idea that should remain recognizable |
| Message hierarchy | Primary message, supporting points and call to action |
| Required brand elements | Approved name, logo, colours, type, product names and distinctive assets |
| Tone and messaging rules | What the campaign should sound like and what it must avoid |
| Prohibited words or concepts | Terms, implications, comparisons or themes that must not appear |
| AI-generated assets allowed? | Yes, no or limited; list permitted formats and tools |
| AI source material | Approved landing pages, product data, brand documents and prior assets |
| Human-created assets only | Claims, testimonials, regulated copy, spokesperson likenesses or other protected assets |
| Required fixed text | Disclosures, qualifiers, legal text, licensing information or offer conditions |
| AI disclosure owner | Person responsible for applying and checking platform and campaign disclosures |
| Rights and consent | Image, voice, music, talent, customer quote and data permissions |
| Accessibility requirements | Captions, contrast, readable type, alt text and audio description where needed |
| Final asset repository | Approved version, file location and naming convention |
Google says AI Max text customization can generate ad copy from a business’s domain, landing pages, existing ads and assets. When Final URL expansion is active, Google may choose another relevant page and create matching copy; pinned responsive-search-ad assets may not serve when a different destination is selected. Record the approved source pages, exclusions and fixed requirements before automation is enabled. [1] [2] For a control-by-control migration plan, use the Google AI Max Migration Checklist.
Google’s “How this ad was made” panel can indicate that an ad was created or edited with AI. Google says its own generative tools are disclosed automatically, while advertisers can use a control for content made with outside AI tools; an on-ad label may also appear based on local requirements. Treat this as a platform disclosure feature, not as proof that the creative, claims, endorsements or other disclosures comply with every applicable requirement. [4]
6. Channel, destination and localization
Give each channel a specific job: create memory, explain, demonstrate, capture intent, retarget, convert or follow up. Then define the destination and market rules before assets are adapted. Localization is more than translation; it includes the offer, currency, service area, spelling, customer expectations, proof, imagery, mandatory wording and response path.
| Field | Required decision |
|---|---|
| Channel and role | What this channel must accomplish |
| Audience and market | Segment, location, language and buying situation |
| Primary landing page | Approved destination and page owner |
| Allowed source URLs | Pages an automated system may use for messaging or destinations |
| URL exclusions | Privacy, careers, outdated offers, unsupported locations, editorial pages or other unsuitable destinations |
| Offer and availability | Price, currency, inventory, eligibility, dates and service boundaries |
| Local proof | Real location, service-area, accreditation or operational facts available for this market |
| Disclosure placement | On-asset, caption, landing page, audio, visual or platform field |
| Localization reviewer | Named person qualified to review the market and language |
| Final destination QA | Mobile experience, message match, form, phone, tracking and confirmation page |
In Google AI Max, URL exclusions can prevent specific pages from serving through Final URL expansion. Google states that Text customization and Final URL expansion must be active for that exclusion control, and eligible pages can influence both the destination and matching text. Exclude any page whose content, offer or geography should not become campaign input. [3]
When a creator, partner or customer has a material connection to the brand, record the disclosure wording and placement for every channel. The Competition Bureau recommends clear, prominent, context-appropriate disclosure on each platform and says reviews and testimonials should reflect actual experience. [7]
Define the organizing idea before listing deliverables, and give every channel a distinct role rather than repeating the same asset everywhere. IPA effectiveness research is a useful reminder to connect short-term activation with longer-term brand effects. [11]
7. Measurement and learning
Define the commercial outcome and the exact optimization event before launch. “Generate leads” is not an event definition. State what action fires the event, where it is recorded, whether it is primary or diagnostic, how duplicates are handled, and how the business will judge lead quality.
| Measure | Required definition | Owner |
|---|---|---|
| Primary business outcome | Qualified commercial change the campaign should influence | Business owner |
| Optimization conversion event | Exact event name and trigger conditions | Analytics owner |
| Event location | Website, phone, CRM, booking tool, app or offline import | Analytics owner |
| Primary or secondary | Whether bidding should optimize toward it or use it for observation | Campaign owner |
| Value and counting rule | Event value, one/every setting, duplicate handling and attribution window | Analytics owner |
| QA evidence | Test date, device, URL, debug record and platform receipt | Analytics owner |
| Sales-quality outcome | Qualified, accepted, booked, won, revenue or another downstream stage | Sales owner |
| Quality guardrail | Fit, cancellations, margin, complaints, retention or invalid leads | Business owner |
| Learning question | Assumption the campaign is designed to test | Campaign lead |
| Decision threshold | Evidence required to continue, change or stop | Business owner |
Google advises that AI Max features work effectively with conversion-based Smart Bidding. That makes the selected conversion event a strategic input, not a technical afterthought. An easily generated but low-value event can train a campaign toward the wrong behaviour. [1]
Attribution helps describe observed paths; incrementality is the stronger question when the business needs to know whether the campaign caused additional outcomes. Record both the reporting model and the limits of the evidence before results are interpreted. [9] [10] Use the First-Party Data and Measurement guide to connect campaign events with consent, CRM outcomes and business-quality signals.
8. Timeline and approvals
| Gate | Named approver | What they confirm | Date and version |
|---|---|---|---|
| Business decision | Commercial owner | Objective, offer, budget and result | Record here |
| Claim evidence | Evidence owner | Accuracy, scope, rights and review date | Record here |
| Brand | Brand owner | Message, visual identity and prohibited language | Record here |
| Compliance and privacy | Qualified reviewer when required | Claims, disclosures, consent and data use | Record here |
| Localization | Local or language reviewer | Market accuracy and cultural or contextual fit | Record here |
| Measurement | Analytics owner | Conversion event, QA and reporting path | Record here |
| Final launch | Final human approver | Exact brief version, assets, automation settings, URLs and tracking | Record here |
- Assign the brief version, commercial owner and campaign decision.
- Have each evidence owner approve the exact claim, source, scope and expiry date.
- Approve the concept, brand rules, prohibited language and required disclosures before asset production.
- Review AI-generated assets, source material, automation settings and URL controls.
- Complete localization, rights, accessibility, landing-page and conversion-event QA.
- Record the final human approver’s name, decision, date and approved version.
- Launch only the approved version and preserve a snapshot of settings and assets.
- Run a mid-flight review under pre-agreed change rules and record any new approval.
- Complete a post-campaign review that separates observed performance from causal claims.
Final human approval: No adaptive or AI-generated campaign should launch only because a platform accepts it. The final approver must confirm that the visible message, likely combinations, destination rules, disclosures, measurement and offer match the approved brief.
Frequently asked questions
How long should a campaign brief be?
Long enough to remove material ambiguity and short enough for every contributor to use. Two to four focused pages often work, with evidence records and technical specifications linked rather than copied into the brief.
What should an AI-ready campaign brief include?
It should identify permitted AI tools and asset types, approved source material, brand and messaging rules, prohibited language, required disclosures, allowed and excluded URLs, rights, localization reviewers and the final human approver.
Can Google AI Max choose a different landing page or write new ad copy?
It can when the applicable asset-optimization settings are enabled. Google says Final URL expansion may choose another relevant page and text customization may generate matching copy, so approved pages and URL exclusions should be set before launch.
Does an AI disclosure label replace legal or campaign disclosure requirements?
No. A platform AI label explains how an asset may have been created. It does not verify the truth of a claim, disclose every material relationship or replace any other disclosure required by the campaign, platform or applicable law.
Who owns the evidence behind a campaign claim?
Assign a named evidence owner who understands the source and can approve its accuracy, scope, permitted use and review date. The campaign team should not broaden the claim beyond what that evidence supports.
Who should give final campaign approval?
A named human with authority over the launch should approve the exact brief version after business, evidence, brand, localization, compliance and measurement reviews are complete.
