2. Check word count against page type minimums
3. Calculate readability metrics
4. Evaluate keyword optimization (natural, not stuffed)
5. Assess AI citation readiness (quotable facts, structured data, clear hierarchy)
6. Check content freshness and update signals
7. Flag potential AI-generated content quality issues per Sept 2025 QRG criteria

| Pillar page | 3,000-5,000 | Comprehensive topic overview |

> **Note:** These are topical coverage floors, not targets. Google confirms word count is NOT a direct ranking factor. The goal is comprehensive topical coverage.

## Readability Targets

| Metric | Target | Tool |

| Flesch Reading Ease | 60-70 (standard) | `article_seo.py --json` |
| Flesch-Kincaid Grade | 7-9 (high school) | `article_seo.py --json` |

Adjust targets by audience:
- Academic/technical: FK Grade 10-12 acceptable
- Consumer/general: FK Grade 6-8 ideal
- Children/education: FK Grade 4-6

## AI Content Assessment (Sept 2025 QRG)

AI content is acceptable IF it demonstrates genuine E-E-A-T. Flag these markers of low-quality AI content:
- Generic phrasing, lack of specificity
- No original insight or unique perspective
- No first-hand experience signals
- Factual inaccuracies
- Repetitive structure across pages
- Listicle-heavy format with shallow coverage
- Over-use of transition phrases ("In this article", "Let's dive in")

> **Helpful Content System (March 2024):** The Helpful Content System was merged into Google's core ranking algorithm during the March 2024 core update. It no longer operates as a standalone classifier. Helpfulness signals are now evaluated within every core update.

## AEO Content Requirements

For Answer Engine Optimization (Featured Snippets, PAA):
- Direct answer in first 40-55 words after matching H2/H3
- Question-phrased H2/H3 tags for PAA targeting
- `<ol>`/`<ul>` lists with 5-9 items for list snippets
- `<table>` with ≤4 columns for table snippets
- No filler phrases before the answer

## GEO Content Requirements

For AI citation and AI Overview inclusion:
- Clear, quotable factual statements (not opinions)
- Structured data (`Article`, `FAQPage` if eligible, `speakable`)
- Brand mentions with consistent entity naming
- `llms.txt` file at site root

## Cross-Skill Delegation

- For evaluating programmatically generated pages, defer to the `seo-programmatic` sub-skill.
- For entity SEO and Knowledge Graph presence, use `entity_checker.py`.
- For topical authority cluster planning, defer to the `seo-plan` sub-skill (section 4.5).
