This skill evaluates content quality across 80 standardized criteria organized in 8 dimensions. It produces a comprehensive audit report with per-item scoring, dimension and system scores, weighted totals by content type, and a prioritized action plan.

When to Use This Skill

• Auditing content quality before publishing

• Evaluating existing content for improvement opportunities

• Benchmarking content against CORE-EEAT standards

• Comparing content quality against competitors

• Assessing both GEO readiness (AI citation potential) and SEO strength (source credibility)

• Running periodic content quality checks as part of a content maintenance program

• After writing or optimizing content with seo-content-writer or geo-content-optimizer

What This Skill Does

• Full 80-Item Audit: Scores every CORE-EEAT check item as Pass/Partial/Fail

• Dimension Scoring: Calculates scores for all 8 dimensions (0-100 each)

• System Scoring: Computes GEO Score (CORE) and SEO Score (EEAT)

• Weighted Totals: Applies content-type-specific weights for final score

• Veto Detection: Flags critical trust violations (T04, C01, R10)

• Priority Ranking: Identifies Top 5 improvements sorted by impact

• Action Plan: Generates specific, actionable improvement steps

How to Use

Audit Content

Audit this content against CORE-EEAT: [content text or URL]

Run a content quality audit on [URL] as a [content type]

Audit with Content Type

CORE-EEAT audit for this product review: [content]

Score this how-to guide against the 80-item benchmark: [content]

Comparative Audit

Audit my content vs competitor: [your content] vs [competitor content]

Data Sources

See CONNECTORS.md for tool category placeholders.

With ~~web crawler + ~~SEO tool connected: Automatically fetch page content, extract HTML structure, check schema markup, verify internal/external links, and pull competitor content for comparison.

With manual data only: Ask the user to provide:

• Content text, URL, or file path

• Content type (if not auto-detectable): Product Review, How-to Guide, Comparison, Landing Page, Blog Post, FAQ Page, Alternative, Best-of, or Testimonial

• Optional: competitor content for benchmarking

Proceed with the full 80-item audit using provided data. Note in the output which items could not be fully evaluated due to missing access (e.g., backlink data, schema markup, site-level signals).

Instructions

When a user requests a content quality audit:

Step 1: Preparation

Audit Setup

Content: [title or URL] Content Type: [auto-detected or user-specified] Dimension Weights: [loaded from content-type weight table]

Veto Check (Emergency Brake)

If any veto item triggers, flag it prominently at the top of the report and recommend immediate action before continuing the full audit.

Step 2: CORE Audit (40 items)

Evaluate each item against the criteria in references/core-eeat-benchmark.md.

Score each item:

• Pass = 10 points (fully meets criteria)

• Partial = 5 points (partially meets criteria)

• Fail = 0 points (does not meet criteria)

C — Contextual Clarity

C Score: [X]/100

Repeat the same table format for O (Organization), R (Referenceability), and E (Exclusivity), scoring all 10 items per dimension.

Step 3: EEAT Audit (40 items)

Exp — Experience

Exp Score: [X]/100

Repeat the same table format for Ept (Expertise), A (Authority), and T (Trust), scoring all 10 items per dimension.

See references/item-reference.md for the complete 80-item ID lookup table and site-level item handling notes.

Step 4: Scoring & Report

Calculate scores and generate the final report:

CORE-EEAT Audit Report

Overview

• Content: [title]
• Content Type: [type]
• Audit Date: [date]
• Total Score: [score]/100 ([rating])
• GEO Score: [score]/100 | SEO Score: [score]/100
• Veto Status: ✅ No triggers / ⚠️ [item] triggered

Dimension Scores

Score Calculation:

• GEO Score = (C + O + R + E) / 4
• SEO Score = (Exp + Ept + A + T) / 4
• Weighted Score = Σ (dimension_score × content_type_weight)

Rating Scale: 90-100 Excellent | 75-89 Good | 60-74 Medium | 40-59 Low | 0-39 Poor

N/A Item Handling

When an item cannot be evaluated (e.g., A01 Backlink Profile requires site-level data not available):

1. Mark the item as "N/A" with reason
2. Exclude N/A items from the dimension score calculation
3. Dimension Score = (sum of scored items) / (number of scored items x 10) x 100
4. If more than 50% of a dimension's items are N/A, flag the dimension as "Insufficient Data" and exclude it from the weighted total
5. Recalculate weighted total using only dimensions with sufficient data, re-normalizing weights to sum to 100%

Example: Authority dimension with 8 N/A items and 2 scored items (A05=8, A07=5):

• Dimension score = (8+5) / (2 x 10) x 100 = 65
• But 8/10 items are N/A (>50%), so flag as "Insufficient Data -- Authority"
• Exclude A dimension from weighted total; redistribute its weight proportionally to remaining dimensions

Per-Item Scores

CORE — Content Body (40 Items)

EEAT — Source Credibility (40 Items)

Top 5 Priority Improvements

Sorted by: weight × points lost (highest impact first)

1. [ID] [Name] — [specific modification suggestion]

   • Current: [Fail/Partial] | Potential gain: [X] weighted points
   • Action: [concrete step]

2. [ID] [Name] — [specific modification suggestion]

   • Current: [Fail/Partial] | Potential gain: [X] weighted points
   • Action: [concrete step]

Recommended Next Steps

• For full content rewrite: use seo-content-writer with CORE-EEAT constraints
• For GEO optimization: use geo-content-optimizer targeting failed GEO-First items
• For content refresh: use content-refresher with weak dimensions as focus
• For technical fixes: run /seo:check-technical for site-level issues

Validation Checkpoints

Input Validation

• Content source identified (text, URL, or file path)

• Content type confirmed (auto-detected or user-specified)

• Content is substantial enough for meaningful audit (≥300 words)

• If comparative audit, competitor content also provided

Output Validation

• All 80 items scored (or marked N/A with reason)

• All 8 dimension scores calculated correctly

• Weighted total matches content-type weight configuration

• Veto items checked and flagged if triggered

• Top 5 improvements sorted by weighted impact, not arbitrary

• Every recommendation is specific and actionable (not generic advice)

• Action plan includes concrete steps with effort estimates

Example

See references/item-reference.md for a complete scored example showing the C dimension with all 10 items, priority improvements, and weighted scoring.

Tips for Success

• Start with veto items — T04, C01, R10 are deal-breakers regardless of total score

These veto items are consistent with the CORE-EEAT benchmark (Section 3), which defines them as items that can override the overall score.

• Focus on high-weight dimensions — Different content types prioritize different dimensions

• GEO-First items matter most for AI visibility — Prioritize items tagged GEO 🎯 if AI citation is the goal

• Some EEAT items need site-level data — Don't penalize content for things only observable at the site level (backlinks, brand recognition)

• Use the weighted score, not just the raw average — A product review with strong Exclusivity matters more than strong Authority

• Re-audit after improvements — Run again to verify score improvements and catch regressions

• Pair with CITE for domain-level context — A high content score on a low-authority domain signals a different priority than the reverse; run domain-authority-auditor for the full 120-item picture
