Quantitative Content Methodology (QCM) treats content not as mere text, but as a mathematical dataset optimized for search engines and LLMs. In this guide, we explain the 5-layer content framework applicable to any topic, step-by-step.

Key Takeaways
• QCM builds pages based on semantic vectors, information density, and probabilistic word distribution.
• An entity pool is extracted prior to production; content is fed from this pool rather than through random word selection.
• An information density budget is defined for each section—targeting at least 2.5 verifiable data points per 100 words.
• The first sentence under every H2 heading serves as an "atomic answer"; it remains meaningful even when extracted from context by an LLM.
• JSON-LD schemas (FAQPage, HowTo, Dataset) present content to search engines as variable-value pairs.

Ranking on the first page is no longer enough. Generative search engines like Google’s AI Overviews, ChatGPT, and Gemini exclusively cite structured, high-information-density pages as sources when generating direct answers to user queries. QCM is an content production framework designed for this new reality.

The 5 layers below represent the methodological steps to be applied at every stage of the production process. We will use "Core Web Vitals Optimization for E-commerce Sites" as our example topic, though the skeleton is adaptable to any industry.

**The 5 Layers of QCM
**Each layer builds upon the previous one. Skipping steps diminishes the effectiveness of subsequent stages.

1. Semantic Vector Map

Before writing, the main entity (core concept) and sub-entities with vectorial proximity are identified. Embedding models (BERT, Sentence-BERT) measure word proximity using cosine similarity. If the content is written while maintaining this cluster distribution, the page signals that it "covers the entire topic."
Layer Entity Proximity Target Frequency
Core Core Web Vitals 1.00 8–12
Primary LCP, INP, CLS 0.85–0.92 4–6
Secondary TBT, TTFB, FCP 0.70–0.80 2–3
Contextual e-commerce, conversion, cart 0.55–0.65 1–2
Authority PageSpeed, Lighthouse, web.dev 0.50–0.60 1–2
Recommendation: Define at least 15 entities for a topic. Fewer leads to superficial content; more leads to topic dilution.

2. Information Density Budget

The minimum concrete information unit—a figure, threshold, procedure, or definition—required per 100 words is pre-calculated per section. This approach prevents the "empty paragraph" syndrome and increases the Information Gain ratio.
• Target Information Gain: At least 1.3x higher than the average of the top 10 competing pages. That is, 30% more verifiable data per 100 words than the competition.

3. Probabilistic Word Distribution

The frequency and placement of key terms are pre-determined. A mathematical balance is established between over-repetition (keyword stuffing) and under-repetition (semantic weakness) based on TF-IDF and BM25 targets.
Important Positioning Rules:
• The core term must appear in the H1, H2, and both the first and last 100 words.
• Primary terms must be positioned in at least one H2 heading.
• Contextual terms should appear 1–2 times within the natural flow without feeling forced.
• Natural readability always takes precedence over frequency targets. These targets are ceilings, not mandates.

4. Structural Skeleton (LLM-friendly layout)

To enable LLMs and AI Overviews to cite content directly, each section is structured as a question-answer atom. The answer is completed in the first sentence; justifications follow in subsequent sentences.
• Atomic Answer Rule: The first sentence under each H2 contains the independently readable answer to the query. Even if an LLM extracts that sentence alone, the information remains accurate and complete.

5. JSON-LD Schema Layer

This structure explicitly notifies Google and LLMs of the page’s mathematical clarity. JSON-LD schemas present information as variable-value pairs. Google bots no longer ask "what is this about?"; they reach the clarity of "The answer to Question A is B."
Key Schemas used in QCM:
• Article: Author, date, publisher info (Mandatory for E-E-A-T signals).
• FAQPage: Each question-answer atom in the FAQ section (Direct candidate for AI Overviews).
• HowTo: For sequential procedures (e.g., LCP reduction steps).
• Dataset: Structured markup for numerical thresholds and tables.
• BreadcrumbList: Page position in site architecture (Critical for topic clusters).
Pre- and Post-Production Audit
Before writing, the following must be answered numerically:
• Has the entity pool been extracted? (Min. 15 entities)
• Is the information density goal set for each section?
• Has the average data point count of the top 10 competitors been measured?
• Is the target Information Gain ratio defined? (1.3x recommended)
Post-publication verification metrics:
• Semantic Coverage: ≥ 85% (via InLinks / Surfer SEO)
• Information Density: ≥ 2.5 (verifiable data / 100w)
• Schema Accuracy: 0 errors (via Rich Results Test)
• LLM Source Test: Top 3 source verification (via ChatGPT / Gemini)
