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
1. **Full 80-Item Audit**: Scores every CORE-EEAT check item as Pass/Partial/Fail
2. **Dimension Scoring**: Calculates scores for all 8 dimensions (0-100 each)
3. **System Scoring**: Computes GEO Score (CORE) and SEO Score (EEAT)
4. **Weighted Totals**: Applies content-type-specific weights for final score
5. **Veto Detection**: Flags critical trust violations (T04, C01, R10)
6. **Priority Ranking**: Identifies Top 5 improvements sorted by impact
7. **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](../../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:
1. Content text, URL, or file path
2. Content type (if not auto-detectable): Product Review, How-to Guide, Comparison, Landing Page, Blog Post, FAQ Page, Alternative, Best-of, or Testimonial
3. 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
```markdown
### 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)
| Veto Item | Status | Action |
|-----------|--------|--------|
| T04: Disclosure Statements | ✅ Pass / ⚠️ VETO | [If VETO: "Add disclosure banner at page top immediately"] |
| C01: Intent Alignment | ✅ Pass / ⚠️ VETO | [If VETO: "Rewrite title and first paragraph"] |
| R10: Content Consistency | ✅ Pass / ⚠️ VETO | [If VETO: "Verify all data before publishing"] |
```
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](../../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)
```markdown
### C — Contextual Clarity
| ID | Check Item | Score | Notes |
|----|-----------|-------|-------|
| C01 | Intent Alignment | Pass/Partial/Fail | [specific observation] |
| C02 | Direct Answer | Pass/Partial/Fail | [specific observation] |
| ... | ... | ... | ... |
| C10 | Semantic Closure | Pass/Partial/Fail | [specific observation] |
**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)
```markdown
### Exp — Experience
| ID | Check Item | Score | Notes |
|----|-----------|-------|-------|
| Exp01 | First-Person Narrative | Pass/Partial/Fail | [specific observation] |
| ... | ... | ... | ... |
**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](./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:
```markdown
## 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
| Dimension | Score | Rating | Weight | Weighted |
|-----------|-------|--------|--------|----------|
| C — Contextual Clarity | [X]/100 | [rating] | [X]% | [X] |
| O — Organization | [X]/100 | [rating] | [X]% | [X] |
| R — Referenceability | [X]/100 | [rating] | [X]% | [X] |
| E — Exclusivity | [X]/100 | [rating] | [X]% | [X] |
| Exp — Experience | [X]/100 | [rating] | [X]% | [X] |
| Ept — Expertise | [X]/100 | [rating] | [X]% | [X] |
| A — Authority | [X]/100 | [rating] | [X]% | [X] |
| T — Trust | [X]/100 | [rating] | [X]% | [X] |
| **Weighted Total** | | | | **[X]/100** |
**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)
| ID | Check Item | Score | Notes |
|----|-----------|-------|-------|
| C01 | Intent Alignment | [Pass/Partial/Fail] | [observation] |
| C02 | Direct Answer | [Pass/Partial/Fail] | [observation] |
| ... | ... | ... | ... |
#### EEAT — Source Credibility (40 Items)
| ID | Check Item | Score | Notes |
|----|-----------|-------|-------|
| Exp01 | First-Person Narrative | [Pass/Partial/Fail] | [observation] |
| ... | ... | ... | ... |
### 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]

- For GEO optimization: use [geo-content-optimizer](../../build/geo-content-optimizer/) targeting failed GEO-First items
- For content refresh: use [content-refresher](../../optimize/content-refresher/) with weak dimensions as focus
- For technical fixes: run `/seo:check-technical` for site-level issues
```

## Example
See [references/item-reference.md](./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
1. **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.
2. **Focus on high-weight dimensions** — Different content types prioritize different dimensions
3. **GEO-First items matter most for AI visibility** — Prioritize items tagged GEO 🎯 if AI citation is the goal
4. **Some EEAT items need site-level data** — Don't penalize content for things only observable at the site level (backlinks, brand recognition)
5. **Use the weighted score, not just the raw average** — A product review with strong Exclusivity matters more than strong Authority
6. **Re-audit after improvements** — Run again to verify score improvements and catch regressions
7. **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](../domain-authority-auditor/) for the full 120-item picture
