1. Normalized 9-Pillar Scoring Rubric (Base 115 → 100%)

Raw pillar weights sum to 115 and normalize to 100.0%: Overall = round(sum(Score_i * w_i) / 115). When semantic evaluation is active on Content & AI pillars, scores blend 70% AEO-Sem typed probabilistic judgment with 30% deterministic checks.

Key	Evaluation Pillar	Raw Weight	Normalized Share
crawl	Crawlability & Indexing	20	17.39%
onpage	On-Page SEO	15	13.04%
content	Content Quality	20	17.39%

3. Research Playbooks — English Knowledge Hub (aeorank.app/learn)

• SEO vs. AEO vs. GEO (2026): Complete Architecture & Roadmap (Markdown .md) — The 2026 SEO, AEO, and GEO Architecture Map is a unified engineering framework for ranking in traditional Google search results while earning brand citations inside generative AI engines (ChatGPT, Perplexity, Gemini, and Google AI Overviews). This guide provides a 3-layer technical comparison matrix and implementation checklist so engineering and content teams can protect organic traffic and capture AI recommendations simultaneously.
• Protected-Field Audit: Fixing Title & Body Year Conflicts (Markdown .md) — A Protected-Field Audit (rule PFA-01 in the 62-rule AEORank engine) is a deterministic verification workflow that detects year and numeric contradictions between four locked metadata fields (<title>, H1, meta description, and FAQ headings) and updated body text. This guide provides the 4-point synchronization checklist to prevent Google from forcibly rewriting your SERP titles and to protect semantic trust scores in AI retrieval pipelines.
• Fake Freshness & The Uniform Sitemap Lastmod Trap (CFA-02) (Markdown .md) — The Fake Freshness and Uniform Sitemap Lastmod Trap (rule CFA-02) occurs when CMS plugins or CI/CD build scripts overwrite the <lastmod> timestamp of every URL in sitemap.xml with today's date despite zero substantive content changes. This guide explains Google Search Central's timestamp verification rules and shows how to pair honest Sitemap signaling with non-commodity content upgrades.
• Diagnosing CTR Drops: Google AI Overviews vs. Competitors (Markdown .md) — Organic CTR Drop Triage is a 4-signal diagnostic method using Google Search Console and live SERP inspection to determine whether falling click-through rates are caused by Google AI Overviews answering queries zero-click or by competitors outperforming your snippet. This guide provides the decision matrix to stop teams from blindly rewriting winning Top-3 title tags and shift toward AEO/GEO source citation.
• Scientific SEO Testing: Control Groups & GSC Data Noise (Markdown .md) — Controlled SEO Experimentation (5 Pilot pages paired with 5 untouched Control pages) is a scientific measurement protocol that isolates the true causal impact of technical or editorial changes from seasonality and algorithm volatility. This guide details the 14-day recrawl burn-in window, the 4-to-6-week evaluation freeze, and how to navigate Google Search Console's 2025–2026 Impression logging changes.
• SEO & GEO Strategy by 3 Website Growth Stages (2026 Matrix) (Markdown .md) — Stage-Aware SEO & GEO Strategy is an engineering resource allocation framework that classifies websites into three distinct lifecycle tiers based on valid Sitemap URL count and estimated search traffic: Early Stage (< 30 URLs), Growth Stage (30–300 URLs), and Mature Stage (> 300 URLs). This guide provides the prioritization matrix and anti-waste guardrails so teams solve their exact current bottleneck and save 70% of wasted effort.
• Google AI Content Rules & The 5-Step Information Gain Guide (Markdown .md) — Information Gain is the measurable degree to which an article contributes new empirical evidence, verified sample data, and decision-making answers that the current Top 10 ranking pages left out. This guide distills Google Search Central's generative AI content rules and provides a 5-step practitioner playbook paired with AEO-Sem semantic scoring so your content avoids lowest-quality ratings and earns AI citations.
• Engineering-as-Backlinks: $0 High-DR Entity Graph Playbook (Markdown .md) — Engineering-as-Backlinks is a technical off-page methodology that converts existing software artifacts—such as OpenAPI 3.0.3 specifications, AI Agent SKILL.md manifests, and SSR architecture deep dives—into verified entity nodes on high-authority developer platforms (DR 72–90) at $0 cost. This guide details the Dual Entity Loop (Schema sameAs + Tier-2 HTML Crawl Bridges) so search engines and LLM RAG pipelines reconcile your brand authority rapidly.
• Multi-Engine RAG Architecture & 8-Tier GEO Framework | AEORank (Markdown .md) — The Multi-Engine RAG Retrieval Architecture and 8-Tier GEO Publishing Framework is an engineering specification for structuring web documents so they pass deterministic technical SEO checks while maximizing passage extraction across Google AI Overviews, Perplexity AI, ChatGPT Search, and Claude Search. This guide combines peer-reviewed KDD 2024 evidence with self-contained semantic passage design to achieve 100/100 AEORank compliance and verifiable AI citations.
