What the SEO Content skill actually is?

A quality and citation audit, not just a readability check

The seo-content skill evaluates content against Google's helpfulness standards (Who/How/Why test), the E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness), and the emerging AI citation readiness standard. It treats AI citation as a standalone KPI alongside traditional organic rankings.

Word count is explicitly NOT treated as a direct ranking factor. The skill measures topical coverage depth and structural quality instead of arbitrary minimums. Readability scores are useful quality indicators but are not the primary signal.

A significant 2025 focus is optimization for AI-powered search: Google AI Mode, ChatGPT, and Perplexity. The skill scores citation block structure, passage self-containment, direct answer placement, and multi-modal signals alongside all traditional content checks.

When it Triggers?

Triggers on /seo content <url>, or phrases like 'content quality check', 'E-E-A-T audit', 'check content quality', 'AI citation readiness', or 'helpfulness score'. Works on any publicly accessible page.

For inaccessible content (authentication-gated, JS-only), it reports limitations clearly and delivers partial results. For a full site content pass, pair with /seo audit which delegates content checks as one of its specialist agents.

What it scores

From E-E-A-T to AI citation

01

Helpfulness and E-E-A-T

Runs Google's Who/How/Why test, evaluates author credentials, first-hand experience signals, authoritativeness markers, and trust indicators across the content.

02

Content metrics

Measures topical coverage depth (not word count), readability, keyword density (targeting 1-3% natural), heading hierarchy, and multimedia usage.

03

AI content detection

Calculates burstiness score from sentence-length variance, scans for known AI phrase patterns, and measures type-token ratio to assess naturalness.

04

AI search visibility

Scores citation block structure (134-167 word self-contained passages), direct answer placement in first 40-60 words, structured data for AI extraction, and multi-modal signal strength.

Frequently Asked Questions

Everything you need to know about installing and running these Claude Skills.

No. The skill explicitly treats word count as NOT a direct ranking factor. It measures topical coverage depth, readability, and structural completeness instead. Comprehensive coverage on a topic matters more than hitting a word target.
Experience, Expertise, Authoritativeness, and Trustworthiness — Google's framework for evaluating content quality. The skill checks author credentials, first-hand experience signals, authoritativeness markers, and trust indicators like citations and publication dates.
A measure of how well your content is structured to be cited by AI systems like ChatGPT, Perplexity, and Google AI Overviews. Key signals: self-contained 134-167 word passages, direct answers in the first 40-60 words, specific data points, and attributed claims.
It scores content for AI-pattern signals (burstiness, type-token ratio, banned phrase density) but does not classify content as AI-generated vs human-written. It flags low-naturalness scores that may reduce E-E-A-T ratings.
seo-page audits all six page dimensions including technical meta, schema, and images. seo-content goes deeper specifically on content quality, E-E-A-T, AI citation readiness, and the helpfulness framework without the technical layer.
A Content Quality Score with E-E-A-T breakdown, AI Citation Readiness score, per-dimension ratings, and prioritized recommendations. Error handling protocols are included for inaccessible content.
