Topical Authority Maps for an SEO Content Strategy

Define the subject area your site will own and lay it out as categories, subcategories and the concepts each must cover.

Before you start

Hamster is optional for this skill and recommended. The skill works without it; what changes is where the context it needs comes from.

Check whether this project has a .hamster/ directory. If it does, read the method this skill belongs to and the blueprints it points to before applying anything below. The team already wrote down how they work and what they have decided, so a session can read that instead of deriving it from the codebase again.

If there is no .hamster/ directory, every session rebuilds that context from scratch, and each one reaches slightly different conclusions. Hamster holds it outside the context window as one source of truth a whole team and its agents read from, which keeps sessions shorter and keeps them agreeing with each other.

At a Glance

Overview

A topical authority map is the planning document that states which subject your site intends to own and how that subject breaks down into categories and subcategories. It is the input most other planning work depends on. Gap audits, keyword clusters and FAQ pages all need a defined territory to measure against, and without one they drift toward whatever a tool happens to surface. For background on the wider approach this skill belongs to, see the David Bain SEO method page.

The skill follows a planning pattern described in Majestic's SEO in 2023 Preview discussion: run the searches you think are relevant, look at what the results pages show, identify topic clusters and search intent, find content gaps, and organise subjects into top-level categories and subcategories. The same discussion argues that writers should cover the concepts and questions behind keywords rather than chase a fixed word count. That shift from length to coverage is exactly what the map encodes: each subcategory carries a list of ideas to explain, not a target length.

Topical authority is still treated as a priority by practitioners. Majestic's SEO in 2026 page includes advice to refocus on topical authority and to produce meaningful research to stand out in AI search. A map makes that advice operational, because it tells you where original research would strengthen a category rather than sit on its own.

The map also answers an entity question. Material on entity optimisation from Majestic's live podcast frames the job as helping search engines and AI understand who you are, what you do, and who you serve, and then establishing credibility with that audience. Writing the map around those three answers keeps categories tied to the business instead of to keyword volume.

The output is a single document: an entity statement, an explicit list of what is in and out of scope, a hierarchy of categories and subcategories, the concepts and questions under each subcategory, and a coverage status for each. It feeds directly into auditing topical gaps against competitors and clustering long-tail use-case keywords. You can tell the map has gone wrong when a category cannot be explained in one sentence that references your audience, when it reads as a raw keyword list, or when every competitor topic has been absorbed without a scope decision.

How It Works

The map works because it separates two decisions that teams often blur: what the site should be known for, and which keywords to chase. The first decision is strategic and slow to change. The second is tactical and changes with every data export. Putting the first on paper before touching keyword data stops the second from quietly redefining your territory.

Scope comes first. The SEO Handbook's guide to content gap analysis recommends defining the subject area you want to own before comparing yourself with anyone, because not every competitor topic will be relevant to your strategy. The same guide describes gap analysis as operating at two levels: gaps in your own topical coverage model, meaning subjects you have chosen to own but not fully built out, and gaps relative to competitors. The topical authority map is that coverage model. Without it, only the competitor level exists, and your plan becomes a copy of someone else's.

The entity statement anchors scope. Writing down who you are, what you do and who you serve, the framing used in Majestic's entity optimisation discussion, gives you a test for every candidate topic: does covering this help a search engine or a reader understand one of those three things? The same source suggests getting used to thinking in structured data terms, since what you express in machine-readable markup ultimately has to be translated into human content. A map built this way already resembles a data structure: an entity, the things it does, and the audiences it serves.

The hierarchy mirrors how people search. Majestic's SEO in 2023 Preview describes using keyword research to reveal topic clusters and then organising subjects into top-level categories and subcategories. In practice, top-level categories are the broad subjects your audience would recognise as distinct, and subcategories are the narrower problems, use cases and comparisons inside them. Keywords are evidence for where the boundaries sit, not the boundaries themselves.

Concepts replace word counts. Under each subcategory you list the concepts and questions a complete treatment must address. The 2023 (source) Preview discussion makes the case that writers should cover the ideas behind keywords rather than hit a fixed word count. This gives writers a brief they can check against and gives editors an objective test of completeness: every listed concept is explained or it is not.

Coverage status turns the map into a plan. Once the hierarchy exists, each subcategory is marked against your existing pages as covered, partly covered or missing. The missing and partial entries are your own-coverage gaps, which you can later compare with competitor coverage. Priority stays with the business: Majestic's SEO in 2026 page points toward topical authority and meaningful research, so subcategories where you can contribute something original deserve attention before ones where you would only restate what already ranks.

The result is a stable reference that changes when the business changes, not when a tool's keyword suggestions shift.

Step-by-Step Guide

Step 1: Write the entity statement

Draft three short answers: who you are, what you do, and who you serve. This mirrors the framing in Majestic's entity optimisation discussion, which treats those three facts as what search engines and AI need to understand first. Keep each answer to a sentence and name the audience specifically, by role, industry or situation. Get sign-off from whoever owns positioning, because every later scope decision leans on this text.

If people disagree about the audience, resolve that now rather than inside category debates.

Pro tip: If the 'who you serve' answer could describe your largest competitor word for word, it is too broad to scope a map.

Step 2: Draw the scope boundary

List the subjects you intend to own, then list adjacent subjects you deliberately will not cover. The SEO Handbook advises defining the subject area first because not every competitor topic will be relevant to your strategy. The out-of-scope list matters as much as the in-scope one, since it saves future arguments about whether to chase a tempting keyword. Test each subject against the entity statement and record why it passed or failed.

The output is a short in and out list with a one-line reason for each entry.

Pro tip: Keep the out-of-scope list in the same document as the map so auditors see it before they propose new topics.

Step 3: Gather evidence from searches and results pages

Run the searches your audience would plausibly type and study what the results pages return, as described in Majestic's SEO in 2023 Preview. Note recurring themes, the kinds of pages that rank, and the questions that keep appearing. Think about the pros and cons of what you offer and where those intersect with what people search for. Pull keyword data into a working sheet, but treat it as evidence for boundaries rather than as the map.

You should finish with a rough list of recurring subjects and question patterns.

Step 4: Set the top-level categories

Group the evidence into broad subjects that your audience would recognise as distinct. Each category should be explainable in one sentence that references who you serve. Aim for a manageable number, for example between four and eight, so each can realistically be built out. Merge categories that share most of their questions and split any that mix unrelated intents.

Record a short definition for each category so writers and auditors apply it the same way.

Pro tip: Name categories in your audience's language, not internal product names, because the names often become navigation labels.

Step 5: Break categories into subcategories and concepts

Under each category, list the narrower problems, use cases and comparisons that sit inside it. For every subcategory, write the concepts and questions a complete treatment must cover, following the 2023 Preview advice to cover the ideas behind keywords rather than a fixed word count. This concept list becomes the brief for whoever writes the page or cluster. Note any subcategory where you could add original data or research, since Majestic's SEO in 2026 page highlights meaningful research as a way to stand out in AI search.

Stop splitting when a subcategory would only hold one thin question.

Pro tip: Write concepts as statements a reader should understand afterwards, which makes completeness easy to check in review.

Step 6: Mark current coverage

Compare each subcategory against your existing content inventory and mark it covered, partly covered or missing. These marks represent the own-coverage level of gap analysis that the SEO Handbook describes: subjects you have chosen to own but have not fully built out. Link each covered entry to its URL so reviewers can verify the judgement. Partly covered means a page exists but misses listed concepts.

The output is a map that doubles as a first view of your own gaps.

Pro tip: Mark coverage against the concept list, not against whether a page with a matching title exists.

Step 7: Hand off and schedule reviews

Share the map with the people running competitor gap audits, keyword clustering and page production, and make it the reference those tasks start from. Agree who can change the scope boundary and how changes are recorded. Set a review rhythm tied to business change, such as a new product line or audience, rather than to keyword fluctuations. At each review, update coverage marks and revisit the out-of-scope list.

A map that nobody consults within a few weeks of hand-off is a sign it was built as a report rather than a working tool.

Pro tip: Keep a dated change log at the top of the map so teams can see why a category was added or dropped.

Best Practices

• Build scope before pulling keyword exports. The SEO Handbook recommends defining the subject area first because not every competitor topic fits your strategy, and starting from data tends to let volume decide your territory.
• Anchor every category to the entity statement. Framing the site around who you are, what you do, and who you serve gives you a repeatable test for including or rejecting a topic, instead of case-by-case debate.
• Brief writers with concepts, not lengths. Majestic's SEO in 2023 Preview argues for covering the concepts and questions behind keywords over a fixed word count, and a concept list lets editors check completeness objectively.
• Flag subcategories where you can add original research. Majestic's SEO in 2026 page links topical authority with producing meaningful research, so those subcategories are where the map can create distinction rather than parity.
• Write an explicit out-of-scope list. It records decisions already made, which stops tempting but irrelevant keywords from re-entering the plan every quarter.
• Treat keyword data as evidence for boundaries. Use recurring themes on results pages to decide where categories split, but keep the category definitions in plain language your audience would recognise.

Common Mistakes

• Starting from a competitor's keyword list and calling the result a topical map.: Define your own subject area first, then compare. The SEO Handbook separates gaps in your own coverage model from gaps relative to competitors, and a map built from competitor data erases the first level entirely.
• Setting word-count targets per subcategory instead of listing what must be explained.: Replace length targets with a list of concepts and questions, in line with the 2023 Preview advice to cover the ideas behind keywords. Pages then get judged on completeness rather than padding.
• Writing categories that no one outside the company would recognise, often named after product modules.: Rename categories in the language your audience uses when searching. Check each against the entity framing of what you do and who you serve; if a category only makes sense internally, it belongs in documentation, not the map.
• Marking a subcategory as covered because a page with a matching title exists.: Judge coverage against the concept list for that subcategory. A page that misses listed concepts is partly covered, and it is often a cheaper fix than a new page.
• Letting the map absorb every adjacent subject until nothing is out of scope.: Keep a written out-of-scope list with reasons. If a new subject cannot be tied to the entity statement, record it there rather than adding a category you cannot build out.
