Blog Analyze

Blog Analyzer: Quality Audit & Scoring

Scores blog posts on a 0-100 scale across 5 categories and provides prioritized improvement recommendations. Includes AI content detection analysis. Works with local files or published URLs.

Reference documents (paths from repo root):

• skills/blog/references/quality-scoring.md: full scoring checklist
• skills/blog/references/eeat-signals.md: E-E-A-T evaluation criteria
• skills/blog/references/ai-slop-detection.md: two-tier reflex methodology (v1.8.0)
• skills/blog/references/editorial-heuristics.md: ordinal 0-4 rubric, P0-P3 severity (v1.8.0, used with --rubric)
• skills/blog/references/cognitive-load.md: per-section concept density (v1.8.0, used with --cognitive-load)

Input Handling

• Local file: Read the file directly
• URL: Fetch with WebFetch, extract content
• Directory: Scan for blog files, audit all (batch mode)
• Flags: --format json|table, --batch, --sort score, --rubric, --cognitive-load

Optional Modes (v1.8.0)

• --rubric: in addition to the 100-point score, emit the ordinal 0-4 editorial-heuristics rubric with P0-P3 severity tags. See skills/blog/references/editorial-heuristics.md. The 100-point JSON schema is preserved; the rubric is added as a sibling rubric field.
• --cognitive-load: run scripts/cognitive_load.py against the post and embed the per-section load heatmap as a sibling cognitive_load field. See skills/blog/references/cognitive-load.md.

Both modes are additive. The default behavior (no flags) is unchanged from v1.7.1.

Scoring Process

Step 1: Content Extraction

Read the blog post and extract:

• Frontmatter (title, description, date, lastUpdated, author, tags)
• Heading structure (H1, H2, H3 with hierarchy)
• Paragraph count and word counts per paragraph
• Statistics (any number claims with or without sources)
• Images (count, alt text presence, format)
• Charts/SVGs (count, type diversity)
• Links (internal, external, broken)
• FAQ section presence
• Schema markup (types present)
• Meta tags (title, description, OG tags, twitter cards)
• Sentence lengths for burstiness analysis
• Vocabulary tokens for diversity scoring

Step 2: Score Each Category

Load references/quality-scoring.md for the full checklist. Score each:

Content Quality (30 points)

Readability Bands (apply per persona, or use default):

Content clarity is the #2 factor for AI citation probability (+32.83% score differential). Average US adult reads at 7th-8th grade level.

SEO Optimization (25 points)

E-E-A-T Signals (15 points)

When scoring source citations under E-E-A-T, evaluate whether each public statistic carries the FLOW evidence triple: year anchor in prose, inline citation with publisher and title, URL with retrieval date in the source block. Posts that cite tier 1-3 sources but lack retrieval dates score lower on this subcategory than posts that include the full triple. See skills/blog/references/flow-alignment.md for the standard.

Technical Elements (15 points)

AI Citation Readiness (15 points)

Step 3: AI Content Detection

Analyze the post for AI-generated content risk:

Burstiness Score (sentence length variance):

• Calculate standard deviation of sentence lengths across the post
• Human writing: high variance (short punchy + long complex sentences)
• AI writing: low variance (consistently medium-length sentences)
• Score: 0-10 scale (10 = very human-like burstiness)

Known AI Phrase Detection: flag occurrences of these 17 phrases:

1. "It's important to note"
2. "In today's digital landscape"
3. "Delve into"
4. "Navigating the complexities"
5. "Let's explore"
6. "Furthermore"
7. "In conclusion"
8. "It is worth mentioning"
9. "Embark on"
10. "Cutting-edge"
11. "Leverage" (as a verb, non-financial context)
12. "Game-changer"
13. "Revolutionize"
14. "Streamline"
15. "Harness the power"
16. "Dive deep"
17. "Unlock the potential"
18. Em dashes (-) - count all instances, flag as AI writing pattern

Vocabulary Diversity (Type-Token Ratio):

• Calculate unique words / total words
• Human writing: TTR typically 0.4-0.6 for long-form
• AI writing: TTR often below 0.35 (repetitive vocabulary)

AI Content Risk Assessment:

• Flag if AI probability > 50% based on combined signals
• Provide specific passages that triggered the flag
• Recommend humanization: personal anecdotes, varied sentence rhythm, domain jargon

Step 4: Determine Rating

Step 4.5: Optional Ordinal Rubric (--rubric)

When --rubric is passed, additionally score the post on the 10 editorial heuristics defined in skills/blog/references/editorial-heuristics.md. Each heuristic gets a 0-4 score and a severity tag (P0 / P1 / P2 / P3 / none).

The rubric does NOT replace the 100-point score. It runs alongside and surfaces which findings are blocking versus which are polish.

Output the rubric as either:

• Markdown table (default) appended to the main report under a ### Editorial Heuristics Rubric heading.
• JSON rubric field when --format json is in use.

Rubric JSON schema:

{
  "rubric": {
    "heuristics": [
      { "id": 1, "name": "Visibility of intent", "score": 3, "severity": "P2", "note": "Summary box generic" },
      ...
    ],
    "p0_count": 0,
    "p1_count": 1,
    "p2_count": 2,
    "p3_count": 3
  }
}

Step 4.6: Optional Cognitive Load Heatmap (--cognitive-load)

When --cognitive-load is passed, run scripts/cognitive_load.py <file> --format json and embed the result under a cognitive_load field in JSON output, or append a ### Cognitive Load Heatmap markdown section in markdown output. See skills/blog/references/cognitive-load.md for thresholds and interpretation.

Step 5: Generate Report
