Content Brief Builder | The Three Streams GEO Methodology
Where this tool fits in the content workflow

A content architecture — built with the Hub-and-Spoke Content Planner — tells you what to publish. A writing brief tells the writer exactly what each piece must contain and why. This tool turns a single piece from your architecture into a complete brief with an article outline, evidence slots, entity rules, and schema requirements.

The brief is grounded in the Three Streams Methodology: entity-first writing, the answer-first architecture, and the self-contained section pattern AI systems use when extracting passages.

Educational Use Only. This tool helps structure a writing brief using frameworks from the Three Streams GEO Methodology. It does not guarantee AI citation, publication quality, or regulatory compliance. Evidence claims (statistics, expert quotes, outbound sources) must be verified, sourced, and — where relevant — reviewed by legal or compliance staff before publication. Following the methodology's principle (Section 2.4), this tool does not prescribe arbitrary word counts for content types — length is determined by topic complexity and the completeness required to answer the question fully.

Piece identity

Identify the specific content piece you're building a brief for. Pulled from your content architecture.

The H1 of the finished page. Use the exact wording the writer should publish.
The type determines structure, required schemas, and which of the GEO techniques apply most.

Hubs and spokes play different roles in the Three Streams architecture. Hubs are short, conversion-focused pages tuned for the branded-objective query — the user is close to a decision and wants specs, proof, and a CTA, not a long essay. Spokes are long-form educational content where AI citation earning happens: statistics, expert quotes, self-contained Q&A sections, outbound sources.

Length is determined by topic complexity and completeness — answering the question fully, regardless of word count. Each spoke subtype emphasises different techniques: comparison articles rely on HTML tables and structured data points; how-tos rely on HowTo schema and numbered sequencing; technology explainers rely on DefinedTerm and dual nomenclature. Picking the right type drives the whole brief.

Reader & context

Who is the reader, where are they in their journey, and what real-world situation brings them to this content?

The job the reader is hiring this piece of content to do for them.

Jobs-to-Be-Done is a framework from Clayton Christensen (Harvard Business School): customers don't buy products, they hire them to do a job. A functional job is a practical task ("compare several vendor options quickly"). An emotional job is about how they want to feel ("feel confident in the decision"). A social job is about how they want to be perceived ("present a well-researched recommendation to my team").

AI system queries are increasingly framed as jobs rather than product searches. Picking the job type shapes the tone, the evidence emphasis, and the closing call-to-action.

Where the reader is in their buying journey. This determines the content type per methodology §3.5.

The opening paragraph is the #1 citation zone — research on ChatGPT citation patterns has shown a substantial share of cited passages comes from the first 30% of a page. If the content type mismatches the reader's stage, the piece gets skipped regardless of how good the opening is. The opening itself follows the universal Answer-First requirements (methodology §6.3); the journey stage determines which kind of content surrounds that opening.

Per methodology §3.5, each journey stage calls for a distinct content type:

  • Awareness — educational content; science foundations; problem explanation
  • Consideration — comparison guides; expert reviews; testimonials; feature breakdowns
  • Decision — authority signals; testimonials; scientific backing; thought leadership

Note on AIDA's "Interest" stage: the classic AIDA funnel splits the early funnel into Awareness and Interest. This tool uses the three-stage model from methodology §3.5 because the two funnel stages produce the same content-type guidance; splitting them would not change the writing instruction.

Situational triggers that bring the reader to your category. A single piece can legitimately address several at once — a "quarterly review preparation" piece is both a when and a why.

Category Entry Points are the real-life situations that cause someone to think about a product category in the first place. The 7W framework (from Professor Jenni Romaniuk, Ehrenberg-Bass Institute) organises CEPs into seven dimensions: Who, What, When, Where, Why, With whom, How (emotional state).

A strong CEP-anchored piece opens by describing the situation before introducing the solution. This matches how real AI queries are phrased — situation-first, product-second. The piece becomes findable through situational queries, not just product queries.

Why multi-select: a single situation usually hits several CEP dimensions at once. "End-of-quarter review preparation" is simultaneously a WHEN (time-based trigger), a WHY (motivation: proving results), and a HOW (emotional state: pressure). Tagging all three gives the writer a richer frame and helps the piece rank against queries phrased through any of those lenses.

Skip this field entirely for foundational explainer pieces not anchored to a specific situation ("How does [category] work?").

Queries & evidence

What questions must this piece answer, and what verifiable evidence will anchor the claims?

One per line. Each one becomes an H2 section in the article outline.

In AI-driven retrieval, each H2 section of your page is effectively a standalone citation unit — AI systems frequently pull a single section rather than paraphrasing the whole page. A page with 6 self-contained H2 sections, each directly answering a real query, gives you 6 chances to be cited rather than 1.

Write queries exactly as a real person would type them: conversational, question-shaped, with the mix they actually use (problem queries, comparison queries, decision queries). These are your sentinel queries — the ones you'll track in ChatGPT, Perplexity, and Gemini to measure citation lift.

Aim for 3–6 queries for a full-length spoke. Hub pages usually have 1–2 queries, tightly branded. FAQ clusters can have 10+.

Queries added: 0
The product, service, brand, or topic this content is really about. Used to enforce entity-first writing rules in the brief.

AI systems use entity recognition to decide what a page is "about." Content that refers to its subject generically ("our product", "this tool", "the [category]") gives AI no signal to connect the content to the underlying entity — so the content effectively becomes invisible to AI-based retrieval for queries about that entity.

The entity-first pattern is simple: on first mention, use the full entity name plus its category (e.g. "[Brand]'s [Product Name] [Category]"); on later mentions, use a shortened but still specific form (e.g. "the [Product Name]"); never use ungrounded generic references.

Decide the evidence at brief stage, not draft stage — this is what separates citable content from filler.

The Princeton GEO Study (Aggarwal et al., KDD 2024) found that adding quotations from credentialled experts improves AI citation rates by 40–44% — the single highest-impact content technique measured. Adding statistics with sources improves citation rates by 30–40%. Source citations to credible outbound sources adds another 30–40%.

These gains only materialise if the evidence is real — named experts, verifiable numbers, Tier-1 sources (peer-reviewed journals, government data, established industry research). Deciding the evidence at the brief stage, rather than leaving it to the writer to invent, is what separates briefs that produce citable content from briefs that produce filler.

A single high-quality statistic and a single named expert quote, placed in the right sections, will usually outperform a piece stuffed with vague claims.

One verifiable number that anchors the piece. Format: "[Number/fact] ([Source], [Year])".
Every field matters. "Experts say…" is not quotable evidence. AI systems need an identifiable, verifiable person.
