‍

What I Mean by “AI Marketing Stack” for Sydney Teams

I define the stack as the minimum set of components that carry work from research to revenue.
I optimize for speed, auditability, and outcomes you can defend in a boardroom.
I avoid tool sprawl and prefer clean handoffs between layers.

Build vs Buy: The 10-Minute Decision Framework

I buy when a capability is commodity and mature.
I build when the work is unique to your narrative, data, or workflow.
I score each capability on Differentiation, Time to Value, and Maintenance Load.
If a capability scores low on differentiation and high on maintenance, I buy it.

Quick rule of thumb.

• Buy the orchestrator and analytics.
• Build briefs, voice, and your knowledge base.
• Mix for website and personalization depending on your CMS and data maturity.

Core Principles I Use in 2025

I design for answer engines first, search engines second.
I keep humans on taste, compliance, and approvals.
I log every step so we can trace outcomes to inputs.
I keep the stack small enough to learn fast and scale without chaos.

The Orchestrator Layer: Where Agents Live

I run an orchestrator + specialist agents model.
The orchestrator assigns jobs to research, writing, design, web, distribution, and revenue agents.
Every job gets an ID, an owner, a due date, and a log of prompts and edits.
This layer kills email ping-pong and creates a repeatable operating system.

What I look for.

• Queue, versioning, and approvals.
• Human override at any point.
• Clear metrics per job.

Research & Insights Layer

I mine demand, beatable pages, and questions LLMs already answer.
I build a question map that informs pillars, FAQs, and briefs.
I add local Sydney signals like suburbs, venues, and seasonal events.

Outputs I expect.

• Top questions with estimated impact.
• Competitor gap list.
• Evidence sources I can cite.

Content Production Layer (Long-Form, Design, Short-Form)

I draft with agents and finish with editors.
I ship answer-first pages, carousels, shorts, and email from one brief.
I keep templates for style, structure, and claims.

Quality gates.

• Accuracy gate.
• Brand gate.
• Compliance gate.

Website & Technical Layer

I need a CMS that supports fast pages, stable URLs, and clean schema.
I prioritize Core Web Vitals, internal links, and server-side rendering for flagship pages.
I keep canonical tags, sitemaps, and robots simple and correct.

My non-negotiables.

• Green CWV on money pages.
• Article, FAQ, HowTo, and Organization schema.
• Image compression and lazy load done right.

Data & Analytics Layer

I measure leading, middle, and lagging indicators.
I connect first-party analytics to the orchestrator so every asset has results attached.
I use consistent UTM conventions and a simple attribution model.

Signals I care about.

• LLM mentions and entity hits.
• Content-assisted sessions and demo requests.
• Pipeline created and revenue contribution.

Distribution & Syndication Layer

Publish is halftime.
I push natively to LinkedIn, X, email, and selected partners.
I syndicate evergreen pieces to earn durable links and citations.
I sample channels weekly and move budget to winners.

Personalization & Lifecycle Layer (Privacy-Safe in AU)

I use zero- and first-party data with a clear value exchange.
I maintain preference centers and frequency caps.
I personalize subject to consent and keep approvals archived.
I respect Australian spam and privacy requirements by default.

Governance, Compliance, and Audit Layer

I keep a one-page risk register with owners and mitigations.
I log prompts, versions, claims, sources, and approvals.
I store change histories for board comfort and future audits.

Security & Access Control

I enforce role-based permissions across the stack.
I restrict production pushes to named approvers.
I remove stale access monthly and keep keys in a vault.

Performance, Reliability, and Ops

I monitor CWV, uptime, and build times.
I automate image optimization and cache rules.
I rehearse rollback and hotfix procedures so launches are safe.

Integration Patterns: The “Connective Tissue”

I prefer webhooks and lightweight APIs over brittle plugins.
I send job IDs and campaign IDs through every system.
I normalize naming so reports stay clean and comparable.

Knowledge Base & Templates

I centralize brand voice, proof library, disclaimers, and legal.
I store approved prompts, briefs, and design blocks.
I tag everything with owners and last-updated dates.

The 90-Day Stack Pilot I Run in Sydney

Weeks 1–2. Narrative, question map, entity list, and stack wiring.
Weeks 3–4. Two pillars, six snippets, one landing page, and distribution.
Weeks 5–6. Schema, internal links, partner syndication, and mention tests.
Weeks 7–8. Refresh winners, expand FAQs, and event-to-feed loops.
Weeks 9–10. Authority pages and template hardening.
Weeks 11–12. Cohort lift review, ROI math, and scale decision.

Costing: OpEx vs CapEx for Sydney CMOs

I prefer OpEx for tools and CapEx-like thinking for assets.
I treat each content pillar as a capitalizable asset that compounds.
I negotiate tool tiers to match your publishing velocity, not vanity features.

Roles & RACI in an Agentic Model

I assign one owner for the content engine.
I give editors veto rights on flagship assets.
I keep marketing ops on the stack and distribution.
I make sales a stakeholder with feedback power, not a bottleneck.

Risks & Kill-Switches

I define disallowed claims and escalation rules.
I keep a kill-switch for any live campaign that crosses risk thresholds.
I track drift in tone, accuracy, or accessibility and fix fast.

The 12-Month Scale Roadmap

Quarter 1 proves the loop and the ROI.
Quarter 2 expands pillars, partners, and refresh cadence.
Quarter 3 adds calculators, guides, and event series.
Quarter 4 hardens governance and explores new channels.

Build vs Buy Cheatsheet (Copy/Paste)

Buy. Orchestrator, analytics, email, project tracking, and basic DAM.
Build. Brief templates, knowledge base, voice, offers, and authority pages.
Mix. CMS choice, personalization depth, and data modeling based on maturity.

The result was durable links, LLM mentions, and qualified demos within one quarter.
