Check both traditional SEO (E-E-A-T) and AI search (citability)
| Dimension | Goal | Key Metrics |
|---|---|---|
| Traditional SEO | Google rankings | E-E-A-T score, keywords, structure |
| AI Citability | ChatGPT/Perplexity citations | Extractability, authority signals, third-party presence |

Compare against page type minimums:
| Page Type | Minimum |
|---|---|
| Homepage | 500 |
| Service page | 800 |
| Blog post | 1,500 |
| Product page | 300+ (400+ for complex products) |
| Location page | 500-600 |
Important: These are topical coverage floors, not targets. Google has confirmed word count is NOT a direct ranking factor. The goal is comprehensive topical coverage — a 500-word page that thoroughly answers the query will outrank a 2,000-word page that doesn't. Use these as guidelines for adequate coverage depth, not rigid requirements.
Note: Flesch Reading Ease is a useful proxy for content accessibility but is NOT a direct Google ranking factor. John Mueller has confirmed Google does not use basic readability scores for ranking. Yoast deprioritized Flesch scores in v19.3. Use readability analysis as a content quality indicator, not as an SEO metric to optimize directly.
Google's raters now formally assess whether content appears AI-generated.
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 weighted within every core update — the same principles apply (people-first content, demonstrating E-E-A-T, satisfying user intent), but enforcement is continuous rather than through separate HCU updates.
Optimize for AI search engines (ChatGPT, Perplexity, Google AI Overviews):
Google AI Mode launched publicly in May 2025 as a separate tab in Google Search, available in 180+ countries. Unlike AI Overviews (which appear above organic results), AI Mode provides a fully conversational search experience with zero organic blue links — making AI citation the only visibility mechanism.
Key optimization strategies for AI citation:
Generative Engine Optimization (GEO):
GEO is the emerging discipline of optimizing content specifically for AI-generated answers. Key GEO signals include: quotability (clear, concise extractable facts), attribution (source citations within your content), structure (well-organized heading hierarchy), and freshness (regularly updated data). Cross-reference the seo-geo skill for detailed GEO workflows.

AI systems extract paragraphs, not entire pages. Each key claim should stand alone.
| Content Block Type | Use Case | Example |
|---|---|---|
| Definition block | "What is X?" | "CRM is software that manages customer relationships..." |
| Steps block | "How to do X?" | "Step 1... Step 2... Step 3..." |
| Comparison table | "X vs Y" | Feature comparison table |
| Pros/cons block | Evaluation queries | "Pros:... Cons:..." |
| FAQ block | Common questions | Q:... A:... |
| Statistics block | Data support | "According to 2025 survey, 73% of users..." |
Structure Rules:
| Optimization Method | Visibility Boost | How to Do |
|---|---|---|
| Cite sources | +40% | Add authoritative citations and links |
| Add statistics | +37% | Specific numbers + source |
| Expert quotes | +30% | "According to [expert]..." |
| Authoritative tone | +25% | Demonstrate expertise |
| Keyword stuffing | -10% | Reduces AI visibility |
Best combination: Fluency + Statistics = Maximum boost
AI doesn't just cite your website, it cites where you appear.
| Platform | AI Citation Share | Action |
|---|---|---|
| Wikipedia | 7.8% | Ensure brand page is accurate |
