Topical Map, a content planning system that connects a main topic with all related subtopics, entities, and search intents in a hierarchical, interlinked, and semantic structure.
A topical map is not just a content strategy framework, it is the epistemological structure of your website. It reflects how knowledge is interconnected, how entities, search intents, and contextual relationships are mapped to one another.
In Semantic SEO, a topical map represents the conscious planning of subject matter, enabling a search engine to perceive a domain as authoritative and complete on a topic. Unlike traditional keyword-centric planning, topical mapping mirrors how Google’s Knowledge Graph and natural language models organize information by entity, attribute, and contextual connection.
Semantic SEO requires websites to behave like ontologies, not blogs.
What Makes a Topical Map Different?
Traditional SEO vs Semantic SEO
Traditional SEO:
- Keyword clusters driven by search volume
- Disconnected blog posts
- Surface-level topical coverage
Semantic SEO:
- Topic clusters driven by entity relationships
- Intent-layered content hierarchy
- Emphasis on completeness, not just coverage
Example: A site selling CBD oil for dogs in traditional SEO may target “best CBD for dogs” and similar variations.
But in semantic SEO, the content must include:
- What is CBD? (entity explanation)
- Dog health topics (contextual anchor)
- Nutrition, behavior, legality, dosage (intent-specific)
- Veterinary perspectives, breed considerations, product comparisons (attribute-driven)
Semantic SEO aims to saturate the search graph with structured meaning.
Step-by-Step: Building a Topical Map from Scratch
- Start With the Central Entity
Identify the main entity that encapsulates your niche. Example: For a pet blog, it may beDog. - Segment into Core Topic Silos
Group content into semantic categories that extend from the main entity. Examples underDog:- Dog Breeds
- Dog Training
- Dog Nutrition
- Dog Health
- Dog Products
- Dog Behavior
- Dog Adoption
- Expand Subtopics Based on Contextual Layers
Break each core topic into sub-entities and attributes. Example forDog Training:- Potty Training
- Leash Training
- Crate Training
- Behavioral Conditioning
- Define Search Intent Per Node
For each node, determine its primary and secondary search intents:- Informational: “How to leash train a puppy?”
- Transactional: “Buy crate for small dogs”
- Navigational: “Dog training near me”
- Map Interlinking Opportunities
Every article must be internally linked with contextually relevant content, forming a semantic web of documents.

Entity, Intent, and Hierarchy in a Topical Map
Entity
An entity is any identifiable, distinct object which is people, places, things, ideas.
In our example:
Dogis the central entityCBD oil,Labrador,Leash Training, andLiver Treatsare supporting entities
Intent
Search intent determines how an entity is approached.
- Is the user seeking to understand (informational)?
- To solve (problem-solving)?
- To buy (transactional)?
Hierarchy
Entities live in taxonomic hierarchies:
- Dog → Dog Breeds → German Shepherd
- Dog → Dog Health → Vaccinations
Each hierarchy must reflect crawling depth and interlinked logic, akin to knowledge graph traversal.
Tools vs Brain: The Human Edge in Topical Mapping
Why Tools Alone Are Not Enough
SEO tools (SEMrush, Ahrefs, Frase) can suggest keywords, but they:
- Don’t understand ontological context
- Can’t reason about search satisfaction
- Rely on string-matching, not semantic parsing
The Brain’s Role
Your brain must:
- Detect topic gaps and information voids
- Organize semantic relationships
- Match user needs to entity coverage
Use tools for expansion, not for ideation.
Practical Example: CBD Oil for Dogs
Let’s assume your main product is CBD oil for dogs. Your topical map should still include:
Dog Health
- Anxiety, joint pain, seizures (contexts where CBD is relevant)
Dog Nutrition
- Supplements, oils, feeding guidelines
Dog Behavior
- Hyperactivity, aggression (benefits of calming aids)
Content Flow:
Central Page: “CBD Oil for Dogs – Benefits, Risks, Usage”
Subpages:
- “How CBD Helps Dog Anxiety”
- “CBD Dosage Guidelines by Breed”
- “Is CBD Safe for Puppies?”
Even unrelated topics (Dog Grooming) may help reinforce authority and interlinking if tied back via lifestyle or care perspective.
Tools and Data Sources
Use the following sparingly to validate not generate your topical map:
- Autocomplete / People Also Ask (PAA): Extract user questions
- Google Trends: Track entity interest over time
- Wikipedia: Understand entity attributes
- SEMrush / Ahrefs: Validate keyword coverage gaps
- Screaming Frog: Check crawl depth and URL hierarchy
- Frase / MarketMuse: TF-IDF comparisons for content depth
Technical Intersections
Structured Data
Use @type schemas (Dog, Product, FAQPage) to encode entity context Tie articles together using sameAs, mainEntity, and about properties
NLP & Machine Understanding
Google’s NLP API and Content Classification models rely on:
- Contextual vectors
- Salient entities
- Intent modeling
Your topical map must mimic and inform these systems.
Advanced Tips for Implementation
- Avoid Cannibalization: Don’t duplicate intent across articles
- No Orphaned Pages: Ensure every article links to and from another
- Prioritize Depth Over Breadth: >5,000 words on “German Shepherd” beats 100 articles on 100 dog breeds with 300 words each
- Topical Completeness > Keyword Density
Conclusion: Why Every Website Needs a Topical Map
Semantic SEO is not a content strategy. It is an information architecture discipline.
Google wants publishers to:
- Provide comprehensive topical coverage
- Structure information like a mini Wikipedia
- Satisfy intent across the entire topic spectrum
A topical map is your blueprint for topical authority. It’s how you align with Google’s vector-based indexing systems, how you ensure no intent is left unsatisfied, and how you architect a site that behaves like a knowledge system, not just a marketing asset.
Next we will discuss about topical map that has 5 main components, these are source context, core section, outer section, central entity, and central search intent.
