The Six-Layer Pyramid is Holistic Radar’s topical map architecture: six layers from source context to revenue, in which semantic SEO forms the foundation and the lowest weak layer caps every layer above it. Layers one to four are semantic SEO, and layers five and six carry the other seven services. The page explains what the pyramid is, its six layers, why semantic SEO forms the base, how it sets the order of work, and how it is measured, then covers each layer’s typical symptom, how the pyramid differs from an SEO checklist, and where it came from, before the free Radar Scan.
What the Six-Layer Pyramid is
The Six-Layer Pyramid is a dependency model of six layers, in which each layer can only perform as well as the layers beneath it allow.
A ranking decline, a weak conversion rate, or a missing AI citation is a symptom. The pyramid identifies which layer produces the symptom before any work is prescribed, so budget is not spent strengthening a layer that a weaker layer beneath it will cap.
The six layers of the Six-Layer Pyramid
The Six-Layer Pyramid has six layers, and the Holistic Radar services attach to them as follows.
| Layer | What it governs | Services at this layer |
|---|---|---|
| L1 Source context and central entity | What the site is, who it serves, and the one central entity every page reinforces | Semantic SEO |
| L2 Query network and attributes | Query paths, question types, and the attributes that pass prominence, popularity, and relevance | Semantic SEO |
| L3 Topical map and content network | Root, seed, and node pages across core and outer sections, joined by bridges, with zero cannibalisation | Semantic SEO |
| L4 Page semantics | Extractive summary, tuple headings, and triple sentences a machine can lift in one pass | Semantic SEO, Conversion Copywriting |
| L5 Retrieval and AI confidence | Crawl, render, cost of retrieval, schema consistency, and citation readiness | Technical SEO, Web Development, AI Search Optimization |
| L6 Task completion and revenue | The page finishes the task, the visitor acts, and measurement proves the revenue | Conversion Copywriting, CRO & Analytics, Paid Media, Email & Lifecycle |
Why semantic SEO forms the base of the Six-Layer Pyramid
Semantic SEO forms the base of the Six-Layer Pyramid because every other service depends on knowing which entity, which demand, and which pages the site is built around.
Technical SEO optimizes pages; the topical map decides which pages exist. Conversion copywriting persuades on a page; the query network decides what that page must answer first. Paid media buys demand; the map shows which demand organic pages have not yet captured. Holistic Radar is a full-funnel agency, and semantic SEO is the layer the whole funnel stands on.
How the Six-Layer Pyramid sets the order of work
The Six-Layer Pyramid sets the order of work by fixing the lowest weak layer first, then measuring whether the layer above it improves.
Higher-layer activity becomes expensive when the foundation is unstable. A redesign on a site with no source context produces a faster site that ranks just as unpredictably. The roadmap therefore starts at the lowest constraint that materially affects the opportunity, and each fix is measured before the next begins.
How the Six-Layer Pyramid is measured
The Six-Layer Pyramid is measured by the Radar Scan, which reads all six layers at once and returns the Holistic Authority Score, the binding constraint, and the three highest-leverage fixes.
The Holistic Authority Score scores five components out of 100: tuple coverage 30, extraction integrity 20, network integrity 20, information gain density 15, and historical depth 15.
The Six-Layer Pyramid compared to an SEO checklist
The Six-Layer Pyramid differs from an SEO checklist because a checklist treats every item as equal, while the pyramid ranks every item by the layer it belongs to.
A checklist of 200 items can be 90% complete and still fail if the missing 10% sits at layer one. The pyramid makes that failure visible, which a checklist cannot do.
Six-Layer Pyramid symptoms by layer
Each layer of the Six-Layer Pyramid produces a typical symptom when it is the binding constraint.
| Layer | Typical symptom |
|---|---|
| L1 Source context and central entity | Google and AI answers describe the business vaguely or confuse it with another |
| L2 Query network and attributes | The site ranks for keywords that do not bring customers |
| L3 Topical map and content network | Publishing grows, rankings stay flat, and pages compete with each other |
| L4 Page semantics | Pages sit on page two and AI answers quote competitors |
| L5 Retrieval and AI confidence | Pages are slow, missing from the index, or never cited |
| L6 Task completion and revenue | Traffic arrives and leaves, and no one knows which queries make money |
The same symptoms drive the constraint check on the Holistic Radar homepage, which gives a first hypothesis in 30 seconds.
Where the Six-Layer Pyramid came from
The Six-Layer Pyramid was developed by Holistic Radar from its own topical map practice across builds such as the 216-page PropxPro architecture and the 400+ page Vital Transportation architecture.
It draws on semantic SEO research on topical authority, query networks, and cost of retrieval, and adds the upper layers that connect coverage to revenue.

The topical map work at layer three is delivered as topical map production, and the reasoning behind the map is in what is a topical map.
Six-Layer Pyramid questions
Why is it a pyramid and not a list?
It is a pyramid because strength at a higher layer cannot compensate for a weak layer underneath it; each layer rests on the one below.
Does every engagement cover all six layers?
Every engagement is diagnosed across all six layers, and the work starts at the lowest weak layer; not every engagement needs work at every layer.
Which layer is most often the constraint?
Layer three, the topical map and content network, is the most common constraint on sites that already publish regularly, because pages were added without attribute assignment.
