Most businesses approach content production reactively: a keyword tool identifies a high-volume query, an article is written to target it, and the process repeats. This approach produces a content library that is broad but shallow — covering many topics superficially rather than any topic comprehensively.
A topical map inverts this approach. Instead of starting with keywords and working backwards to topics, it starts with topics and works forward to the full set of content that would constitute comprehensive coverage. The result is a content programme that builds topical authority systematically — and that produces compounding ranking improvements as the topic cluster matures.
The 7-Step Topical Map Process
Define Your Core Topics
Start by identifying the 3–7 core topics that represent the full scope of your business's expertise. These become the 'hubs' of your topical map — the subjects around which all other content is organised.
For a London SEO agency, core topics might be: Technical SEO, Local SEO, Semantic SEO, Link Building, Content Strategy, B2B SEO, and Ecommerce SEO. Each core topic will generate a cluster of supporting content.
Tools to use
Map the Question Space
For each core topic, systematically identify every question a potential customer might ask — from basic awareness questions to advanced decision-stage queries. This is the most important and most time-consuming step.
Use a structured question framework: What is X? How does X work? Why does X matter? How do I do X? What are the types of X? How much does X cost? What are the alternatives to X? What are the common mistakes with X? How do I measure X?
Tools to use
Organise Into a Hierarchy
Group the questions and sub-topics into a three-tier hierarchy: hub pages (core service topics), primary spoke articles (main supporting topics), and secondary depth articles (specific questions and long-tail topics).
Hub pages are typically your service pages. Primary spokes are the main educational articles that support each service — the 'What is X?' and 'How to do X' articles. Secondary depth articles cover specific sub-questions, comparisons, and long-tail topics.
Tools to use
Audit Existing Content
Map your existing content against the topical map to identify what already exists, what needs updating, and what is missing. This gap analysis is the most actionable output of the mapping process.
For each planned page in the topical map, note whether: the page exists and is comprehensive, the page exists but needs updating, or the page does not exist. Prioritise gaps that represent high-traffic opportunities or that block the coherence of the topic cluster.
Tools to use
Design the Internal Linking Architecture
For each page in the topical map, define the internal links it should send and receive. Hub pages should link to all primary spokes. Primary spokes should link back to the hub and to related spokes. Secondary articles should link to the relevant primary spoke.
Document the internal linking structure in the topical map itself — not as an afterthought during content production. This ensures that every article is written with its linking relationships in mind, and that the overall architecture communicates the topical hierarchy clearly to Google.
Tools to use
Prioritise and Sequence
Determine the publication order based on: commercial importance (which topics drive the most revenue?), competitive opportunity (where are competitors weakest?), and topical coherence (which articles are prerequisites for others?).
A common sequencing principle: publish hub pages first, then primary spokes in order of commercial importance, then secondary depth articles. Avoid publishing secondary articles before their parent primary spoke exists — this creates orphan content that cannot benefit from the hub's authority.
Tools to use
Build a Publication Calendar
Convert the prioritised topical map into a publication calendar with specific dates, assigned authors, and target word counts. A realistic calendar for most businesses is 2–4 articles per month.
Include in the calendar: publication date, article title and target URL, primary keyword, target word count, internal links to include, and the author responsible. Review the calendar quarterly and update based on new keyword opportunities and content performance data.

What a Topical Map Looks Like in Practice
A topical map is typically structured as a spreadsheet or database with columns for each piece of metadata needed to plan and track content production. A minimal topical map entry includes:
| Page Title | Target URL | Type | Stage | Priority | Status | Internal Links From |
|---|---|---|---|---|---|---|
| SEO Services London | /freelance-seo-consultant-london/ | Hub | Decision | P1 | Live | All spokes |
| What is Topical Authority? | /blog/what-is-topical-authority/ | Primary Spoke | Awareness | P1 | Live | Hub, O27, O28 |
| How to Build a Topical Map | /blog/how-to-build-topical-map/ | Primary Spoke | Consideration | P1 | Live | Hub, O26 |
| Content Clusters vs Pillar Pages | /blog/content-clusters-vs-pillar-pages/ | Secondary Spoke | Consideration | P2 | Planned | O26, O27 |
Example rows from an SEO services topical map. A complete map for a single service area typically contains 40–100 entries.

Frequently Asked Questions
What is a topical map in SEO?
A topical map is a structured document that maps the full semantic space of a topic — every question, sub-topic, and angle that constitutes comprehensive coverage of a subject area. It serves as the content architecture blueprint for a website, defining what pages need to exist, how they relate to each other, and in what order they should be published.
How detailed should a topical map be?
A topical map should be detailed enough to identify every significant content gap in your current coverage. For most businesses, this means mapping 3–5 levels of depth: core service topics, primary supporting topics, secondary depth topics, and long-tail question content. The map should include the intended URL, content format, target audience stage, and internal linking relationships for each planned page.
How long does it take to build a topical map?
Building a thorough topical map for a single service area typically takes 8–20 hours of research and planning. For a business with multiple service lines, a complete topical map covering all service areas can take 40–80 hours. The investment is justified by the efficiency gains in content production — a well-built topical map eliminates the time spent deciding what to write and ensures every piece of content contributes to a coherent authority-building strategy.
