A topical map is a semantic blueprint that defines how a website aligns itself with search engine understanding. It connects your monetization strategy with the central entity, defines search intent, and distributes topics across a core and outer section. These five components of a topical map create the foundation for semantic relevance, crawl efficiency, and topical authority.
In this article, we will break down the five components of a topical map:
- Source Context
- Central Entity
- Central Search Intent
- Core Section of Topical Map
- Outer Section of Topical Map
Each of these elements functions as a semantic layer, organizing your site’s topics not just by keyword, but by purpose, hierarchy, and context.
1. Source Context
Definition:
The source context defines the monetization model and the functional purpose of the website. It answers the question: What type of business is this site built to serve?
Source Context = Business Model (Monetization)
Examples:
- An eCommerce site like Amazon has a source context of product sales
- A local dog training business may monetize through service bookings
- A course platform (e.g., selling online dog training) monetizes via course sales
- A visa consultancy site may convert traffic into clients through consultation calls or form fills
Every website must clearly articulate its source context so the topical map can anchor content planning to business outcomes. Without defining this, you risk misaligning search intent and monetization logic.
A single niche, like dog training, can have multiple source contexts:
- Local service bookings
- Online course enrollments
- Affiliate product recommendations
The topical map must begin with an accurate classification of the source context, as it will shape every downstream decision in content structure.

2. Central Entity
Definition:
The central entity is the main subject or concept around which all subtopics are structured. It is the semantic core of the domain.
In Semantic SEO, an entity is not just a noun, it is a defined object in the knowledge graph with:
- Attributes
- Relationships
- Contextual variations
Examples:
- In a site about “Dog Training,” the central entity is Dog
- In a visa consultancy website focused on Germany, the central entity is Germany
- In an electric vehicle site, it may be Electric Car
The central entity appears repeatedly and logically throughout content:
- Germany Visa
- Germany Student Visa
- Germany Work Visa
This recurring semantic anchor allows Google to associate every subpage with the same entity frame. The goal is to make the website the reference source for that central entity across various queries.
3. Central Search Intent
Definition:
The central search intent is the primary user need that connects the central entity with the source context. It forms the bridge between what the user is searching for and how the website fulfills that intent.
This used to be called a “keyword,” but under semantic indexing, it is better framed as:
- An intent expression
- A transactional pathway
- A contextual connector between entity and action
Examples:
- In “Dog Training Near Me,”
- Central Entity = Dog
- Source Context = Local Training Service
- Central Search Intent = Book a dog training session
- In “Germany Student Visa Process,”
- Central Entity = Germany
- Source Context = Visa Consultancy
- Central Search Intent = Apply for a Germany Student Visa
The central search intent should be reflected in:
- Page titles
- Structured data
- URL slugs
- Internal link anchors
This aligns the semantic context of the content with the behavioral expectation of the user, creating high-intent entry points that Google can prioritize.
4. Core Section
Definition:
The core section includes all the topics, queries, and pages that directly drive conversions or support the monetization model defined in the source context.
These are your commercially valuable queries, the ones that:
- Generate leads
- Result in bookings
- Drive sales
- Capture micro-conversions (email opt-ins, demo requests)
Examples in different contexts:
- Visa Consultancy Site:
- Germany Student Visa
- Germany Work Visa
- Germany Visa Application Form
- Dog Training Site:
- Potty Training for Puppies
- Obedience Commands
- Book Dog Training Sessions
The core section pages should be:
- Deeply structured with schema
- Linked from homepage or pillar pages
- Used in high-frequency internal link contexts
- Optimized for transactional or solution-driven search intents
These pages are not just topical, they are monetizable.
5. Outer Section
Definition:
The outer section consists of informational and supporting content that may not directly convert but plays a vital role in:
- Increasing topical relevance
- Enhancing crawl depth
- Improving historical data
- Strengthening topical authority
These topics:
- Capture long-tail queries
- Bring in broader traffic
- Help build semantic bridges between core topics
Examples:
- Dog Nutrition
- Behavioral Issues in Dogs
- Best Dog Toys for Anxiety
- How to Calm a Barking Puppy
Though these pages may not generate revenue directly, they:
- Feed Google more engagement signals
- Create contextual reinforcement for the central entity
- Drive users deeper into the site, improving behavioral metrics
Informational content influences rankings through historical data.
Summary of the Five Components of a Topical Map

| Source Context | Defines monetization model | Aligns content with business objectives |
| Central Entity | The core subject of the domain | Establishes semantic identity |
| Central Search Intent | Primary query bridging entity and conversion | Targets high-intent, high-relevance traffic |

| Outer Section | Informational, supporting content | Expands authority and historical data |
Conclusion
A topical map is not about keyword clustering, it is about semantic structuring. Each of these five components serves a unique purpose in building a contextually rich, intent-aligned, and monetizable website.
By clearly defining:
- What your site does (Source Context)
- Who or what it serves (Central Entity)
- How it solves problems (Central Search Intent)
- Where it earns (Core Section)
- And how it builds authority (Outer Section)
