CMO Rulebook turns a KPI signal — rising CAC, falling ROAS, email collapsing — into a structured channel diagnosis, budget rationale, and board-ready narrative. No data feeds. No AI guesswork. Built by a digital and marketing leader for a £450M global brand with a worldwide footprint.
Every module is purpose-built for a specific decision context. They share the same state — your KPI signals, business model, and growth stage — so outputs are coherent across the session.
Reads your KPI pattern across acquisition, retention, and brand — together, not in isolation. Outputs a prioritised action plan and the strategic logic to defend each decision in front of leadership.
Structures your performance story in commercial terms — risk framing, directional recommendation, and opportunity narrative. Built for the room where data literacy is low and stakes are high.
Analyses 30+ channel KPIs across paid search, paid social, SEO, email, affiliate, marketplace, and AI visibility. Identifies where performance is being lost in the funnel and frames the likely root cause.
Model spend reallocation across channels using Hill response curves. Test scenario assumptions before you walk into the CFO conversation — with the efficiency logic mapped and visible.
Generate a structured campaign plan from your objective, channel mix, audience, and budget. Includes channel briefs, KPI targets, and execution priorities — in a format that reduces briefing overhead.
Map your current measurement framework against best-practice coverage across the funnel. Identifies blind spots in attribution, channel tracking, and reporting before they become board questions.
No integrations. No setup. Open the toolkit, select your role, and run your first strategic analysis.
Select your role — CMO, Head of Digital, or Marketing Manager. Set your business model and growth stage. The system calibrates everything to your specific situation.
Input your current performance metrics. The engine reads them together — not in isolation — identifying what the pattern means and where the real problem is.
Get a strategic diagnosis, prioritised action plan, board-ready narrative, and budget scenarios. Structured outputs you can use immediately — in any leadership conversation.
Three modes, three decision contexts. Every output is structured, prioritised, and usable in the next conversation — not a report that requires interpretation.
Acquisition efficiency is deteriorating while retention remains strong — a structural re-allocation signal, not a demand problem.
CPC rising 34% QoQ with flat CTR suggests audience-to-intent mismatch, not bid strategy. Landing page or match type is the more likely root cause.
Objective: grow qualified pipeline by 25% in Q3. Primary channel: paid search + email nurture. Budget: £40k.
The toolkit adapts to your role and accountability level — not the other way around.
Accountable for commercial outcomes, board confidence, and the resource allocation decisions that define how the business grows. The toolkit is built around the decisions you actually face.
Open the ToolkitSee the complete performance picture across acquisition, retention, and brand — and identify where the real strategic issue is, not just where the numbers are red.
Structure your performance story in commercial terms — risk framing, opportunity narrative, and directional recommendation — not a data summary.
Build a structured case before the CFO builds one against you. Model scenarios, identify inefficiencies, and frame trade-offs with the underlying logic visible.
You own the digital channels, the performance numbers, and the translation of strategy into channel execution. The HoD engine gives you structured diagnosis, not just reported symptoms.
Open the ToolkitAnalyse 30+ metrics across paid search, paid social, SEO, CRO, email, affiliate, marketplace, and AI visibility — with context for what each signal actually means.
The engine identifies where performance is being lost in the funnel and frames the likely root cause — so your action addresses the problem, not the number.
Generate a prioritised action plan for today, this week, and this month — adapted to your channel mix, business model, and current KPI pattern.
You operate at the intersection of strategy and delivery. Translating leadership intent into team priorities without losing coherence is the hardest part of the role — the toolkit removes the guesswork.
Open the ToolkitMove from "a long list of things we could do" to a structured, defensible priority list — grounded in KPI signals and business model context, not gut feel.
Understand where your spend is efficient, where it is not, and how to frame trade-offs in terms that resonate with finance and leadership.
Generate structured briefs your team can act on immediately — removing the interpretation overhead that creates misalignment between strategy and execution.
You manage campaigns, channels, and budgets — and the challenge is always prioritisation. The Marketing Manager mode gives you the structure to work smarter with the same time and resource.
Open the ToolkitGenerate a structured campaign plan from your objective, channel mix, and budget — with KPI targets, channel briefs, and execution priorities in one output.
Access pre-built briefs for each major digital channel — covering objectives, tactics, KPIs, budget logic, and the pitfalls most likely to derail the plan.
When everything feels urgent, the system identifies what actually matters — so your time and budget land where they have the most commercial impact.
Every KPI signal you diagnose at channel level is also a strategic question forming in your CMO's mind. The gap between those two readings is where budget decisions, board narratives, and career moments get made.
ROAS has declined 18% in paid social. Media efficiency is down across the upper funnel.
Is the acquisition model structurally broken — or is this a media efficiency problem that reallocation can fix? Which answer survives a board challenge?
CAC is rising quarter on quarter. New customer volume is holding but the cost per acquisition has moved.
At what CAC threshold does our growth investment case become indefensible? And how close are we to that number right now?
Email open rates are strong but conversion to purchase has dropped for three consecutive weeks.
Engagement is not converting — is this a CRM strategy failure, a product fit signal, or a pricing issue? The board answer depends entirely on which one it is.
CMO mode is included in your access
Run the full CMO diagnostic on the same signals you're analysing as a Head of Digital or Marketing Manager. See where the strategic narrative aligns with your channel diagnosis — and where it doesn't — before you walk into the room.

CMO Rulebook is built primarily for Heads of Digital, Marketing Managers, and performance leads who need to explain what the data means to commercial leadership — and who have to defend that position without a strategy team behind them.
It is also used by CMOs, Marketing Directors, and fractional or interim marketing leaders who need a repeatable diagnostic framework they can apply quickly across different business contexts.
It is not the right tool for teams whose primary need is data visualisation or campaign reporting. If what you need is a dashboard, this serves a different function.
No. CMO Rulebook uses structured diagnostic logic — not a general-purpose language model. Every output is the result of a rules-based decision engine that responds to your specific KPI signal, business model, and growth stage. The logic is deterministic, consistent, and explainable.
Given the same inputs, it produces the same output every time — which is precisely what makes it citable in a board setting. You can read the full methodology at /methodology.
Dashboards tell you what happened. CMO Rulebook tells you what to do about it — and gives you the commercial logic to defend that decision in front of the board, CFO, or your leadership team.
Most senior marketing leaders are not short of data. They are short of structured thinking about what the data means strategically and what it requires of the business. This is a decision engine, not a reporting layer.
No setup required. CMO Rulebook runs entirely in your browser — no account to create, no data to upload, no integration required. You open it, select your role, enter your KPI signal and business context, and generate your first output in the same session.
Access details are sent to your email shortly after your request is confirmed.
£25/month, or £199/year. Enter your KPI signal, set the context, and get a structured diagnosis — board-ready output in under ten minutes.
