/seo content evaluates any page against Google’s E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) as defined in the September 2025 Quality Rater Guidelines update. It scores each of the four pillars, applies Google’s own Who/How/Why heuristic from the helpful-content guide, checks AI citation readiness, and flags content that risks triggering scaled content abuse signals. Every audit also includes actionable rewrite recommendations tied directly to the failing sub-factors.
Syntax
Google’s Who / How / Why Test
Before scoring E-E-A-T sub-factors, Claude SEO applies Google’s own three-question heuristic from the helpful-content guide. Every page must answer all three clearly:| Question | What Auditors Look For |
|---|---|
| Who created it? | Visible byline, author bio page, professional credentials. Required wherever readers expect it; non-negotiable for YMYL topics. |
| How was it created? | Process disclosure where readers would reasonably ask — especially for AI-assisted content. Original research, first-hand evidence, lived experience. |
| Why does it exist? | ”To help people” rather than “to attract search clicks.” Watch for niche entry without expertise, content churn for freshness signals, content written to a word-count target. |
The Four E-E-A-T Pillars
Experience
Weight: 20%First-hand knowledge and personal involvement with the topic.
- Original research, case studies, before/after results
- Personal anecdotes with verifiable specific details
- First-hand photos, screenshots, or process documentation
- Unique proprietary data not reproducible from secondary sources
Expertise
Weight: 25%Formal qualifications, training, and demonstrated topical knowledge.
- Author credentials, certifications, and visible byline
- Technical depth appropriate for the target audience
- Accurate, well-sourced claims with current references
- Specialized vocabulary used correctly
Authoritativeness
Weight: 25%Recognition by others as a go-to source in the field.
- External citations and brand mentions from authoritative sites
- Author recognized as an expert (publications, speaking, industry awards)
- Content cited by other authoritative sources
- Consistent publication history in the topic area
Trustworthiness
Weight: 30% — the most heavily weighted pillarOverall reliability, transparency, and absence of deceptive practices.
- Contact information, physical address, privacy policy, terms of service
- Transparent corrections and visible date stamps
- Secure HTTPS with valid SSL certificate
- Customer testimonials and reviews
- No hidden ads, clickbait, or deceptive practices
September 2025 QRG Alignment
The September 2025 Quality Rater Guidelines update introduced two changes directly audited by/seo content:
- YMYL expanded to political and social topics. Pages covering elections, democratic processes, or civic trust are now held to the same standard as health and financial advice.
- AI content assessment formalized. Raters now explicitly assess whether content appears AI-generated. AI-generated content is acceptable if it meets Search Essentials and demonstrates genuine E-E-A-T; it is penalized when used to scale low-value pages (QRG §4.6.5 scaled content abuse, §4.6.6 low-effort main content).
AI Content Assessment
- Acceptable AI Content
- Low-Quality AI Markers
AI-generated content passes the
/seo content quality check when it:- Demonstrates genuine E-E-A-T signals (specific facts, author attribution, process disclosure)
- Provides unique value not available on competing pages
- Has visible human oversight and editing
- Contains original insights beyond commodity information
- Has author attribution even when AI-assisted
v2 Content Quality Additions
Version 2 (Phase B) shipped four new content quality tools that run automatically inside/seo content:
- Filler detector — identifies sentences that add word count without adding informational value, keyed to QRG §4.6.5 and §4.6.6
- AI-pattern humanizer — flags recurring AI output patterns (generic transitions, vague lead sentences, hedge-stacking) and suggests specific rewrites
- Claim-verification scanner — checks factual claims against a primary-source changelog (
data/google-updates.json) and flags outdated assertions - Expired-domain heritage check — queries WHOIS to detect whether the domain was previously used for unrelated content, which can create inherited trust penalties
Content Metrics Reference
Word counts are topical coverage floors — not targets. Google has confirmed word count is not a direct ranking factor. These minimums indicate adequate coverage depth:| Page Type | Minimum Words |
|---|---|
| Homepage | 500 |
| Service page | 800 |
| Blog post | 1,500 |
| Product page | 300+ (400+ for complex products) |
| Location page | 500–600 |
AI Citation Readiness
/seo content includes a GEO-layer score that measures how ready the content is to be cited by AI Overviews and AI Mode. For a full analysis, use /seo geo — but /seo content surfaces the headline signals:
- Clear, quotable statements with specific statistics and source attribution
- Answer-first formatting for key questions
- Strong H1→H2→H3 heading hierarchy
- Tables and lists for comparative data
- Entity clarity: brand, authors, and key concepts clearly defined
/seo content-brief <topic>
/seo content-brief generates a research-backed content brief before a page is written, giving writers a competitive advantage from the first draft. It covers:
- Primary and secondary target keywords with placement rules per section
- Search intent classification (informational, commercial, transactional, navigational) and the SERP format Google rewards for this query
- Competitor analysis — top 5 ranking pages scored on depth, formatting, SEO, and UX; three gap types identified (topic gaps, depth gaps, quality gaps)
- Section-by-section heading outline with word count targets, format notes (table, list, definition box), and Featured Snippet targets
- Internal link recommendations — 3–5 specific targets pulled from the site’s actual sitemap
- Unique angle and information gain — the exact new value this piece adds that no current ranking page provides (proprietary data, case studies, original synthesis — never “more detail”)
- E-E-A-T requirements — the specific trust signals this content needs given its topic
