Blog Rewriter -- Optimize Existing Posts

Rewrites and optimizes existing blog posts for dual ranking: Google search and AI citation platforms. Preserves the author's voice while applying the 6 pillars of optimization.

Key references:

• references/quality-scoring.md - 5-category scoring (Content 30, SEO 25, E-E-A-T 15, Technical 15, AI Citation 15)
• references/eeat-signals.md - Experience, expertise, authority, trust markers
• references/internal-linking.md - Linking strategy and anchor text rules
• references/visual-media.md - Image sourcing and chart styling

Workflow

Phase 1: Audit (Read-Only)

1. Read the blog post - Detect format (MDX, markdown, HTML)
2. Run the quality checklist against references/quality-scoring.md:
   • Count fabricated vs sourced statistics
   • Check answer-first formatting (H2 -> stat in first sentence?)
   • Count images and charts (type diversity?)
   • Measure paragraph lengths (any > 150 words?)
   • Check heading hierarchy (H1 -> H2 -> H3, no skips?)
   • Look for FAQ schema
   • Check freshness signals (lastUpdated, dateModified)
   • Assess self-promotion level
   • Evaluate citation tier quality
3. AI content detection scan:
   • Burstiness score - Measure sentence length variance across the post. Low variance (most sentences within 3-5 words of each other) is a strong AI signal. Calculate: standard deviation of sentence word counts. Target SD > 6.
   • Known AI phrase scan - Check for these high-frequency AI phrases:
     • "in today's digital landscape", "it's important to note", "dive into"
     • "game-changer", "navigate the landscape", "revolutionize", "seamlessly"
     • "cutting-edge", "harness the power of", "leverage" (as verb)
     • "delve", "crucial", "elevate", "foster", "landscape" (overused)
     • "multifaceted", "robust", "tapestry", "embark"
     • Full list in agents/blog-writer.md
   • Vocabulary diversity - Calculate Type-Token Ratio (TTR): unique words / total words. Low TTR (< 0.40) suggests AI-generated repetitive phrasing. Target TTR > 0.50 for natural prose.
   • AI content percentage estimate - Based on burstiness, phrase density, and TTR, estimate what percentage of the content reads as AI-generated (0-100%). Report as: "AI content estimate: ~X%"
4. Video embed check:
   • Count existing YouTube embeds in the post
   • If 0 embeds, flag: "No video embeds. YouTube has the strongest AI visibility correlation (0.737)"
   • If present, check: lazy loading? aria-labels? noscript fallback? VideoObject schema?
5. Cannibalization check:
   • Identify the post's primary keyword from title, H1, and first paragraph
   • Search the blog directory for other posts targeting the same keyword:
     • Grep headings and meta descriptions across all blog posts
     • Flag any posts with significant keyword overlap
   • If cannibalization found, report:
     • Which posts compete for the same keyword
     • Recommend: merge (combine into one stronger post) or differentiate (shift one post to a related but distinct keyword)
6. Calculate current score across 5 categories:
   • Score across 5 categories (Content Quality 30, SEO Optimization 25, E-E-A-T Signals 15, Technical Elements 15, AI Citation Readiness 15)
   • Total: 0-100
7. Present audit summary with specific findings, AI detection results, video status, cannibalization status, and score
8. Enter plan mode - Present section-by-section optimization plan

Wait for user approval before proceeding.

Phase 2: Research

1. Identify the blog's core topic from existing content
2. Find replacement statistics for any fabricated/unsourced data:
   • Search: [topic] study 2025 2026 data statistics
   • Target tier 1-3 sources only
3. Find images if post has fewer than 3:
   • Pixabay: site:pixabay.com [topic keywords]
   • Unsplash: site:unsplash.com [topic keywords]
   • Verify each URL returns HTTP 200
   • If nanobanana-mcp is configured, offer AI generation for missing/insufficient images via blog-image
4. Plan charts if post has fewer than 2:
   • Identify data suitable for visualization
   • Select diverse chart types

Phase 3: Chart Generation (Built-In)

When the post needs more visual elements, invoke the blog-chart sub-skill:

1. Select chart type using the diversity rule (no repeated types per post)
2. Pass: chart type, title, data values, source, platform format
3. Embed the returned SVG directly within a <figure> wrapper
4. Target 2-4 charts per 2,000-word post

See references/visual-media.md for chart type selection and styling rules.

Phase 4: Content Rewrite

Apply changes in this order:

4a. Preserve What Works

• Keep the author's voice and unique perspective
• Preserve original insights and first-hand experience
• Keep existing quality images and charts
• Maintain internal links

4b. Fix Frontmatter

• Add lastUpdated: "YYYY-MM-DD" (today's date)
• Keep original date unchanged
• Fix meta description: fact-dense, 150-160 chars, includes 1 statistic
• Add coverImage + coverImageAlt + ogImage if missing
  • Search Pixabay/Unsplash/Pexels for wide hero image (1200x630)
  • Or generate custom SVG cover via blog-chart (text-on-gradient with key stat)
  • Or generate custom AI image via blog-image sub-skill (if nanobanana-mcp configured)
• Verify tags/categories are appropriate

4c. Apply Answer-First Formatting

Every H2 section MUST open with a 40-60 word paragraph containing:

• At least one specific statistic with source attribution
• A direct answer to the heading's implicit question

4d. Replace Fabricated Statistics

• Search for patterns: "X% of...", "X out of Y...", unsourced claims
• Replace with real data from tier 1-3 sources
• Always include inline attribution: ([Source Name](url), year)

4e. Improve Headings

• Convert statement headings to questions where natural (60-70% target)
• Keep 2-3 statement headings for variety
• Ensure keyword appears in 2-3 headings naturally

4f. Fix Paragraph Length

• Split any paragraph > 150 words
• Target 40-80 words per paragraph
• Ensure each paragraph starts with its most important sentence

4g. Add Visual Elements

• Embed new images after H2 headings, spaced evenly
• Embed charts within relevant sections
• If nanobanana-mcp configured: generate custom images for sections lacking good stock matches (invoke blog-image sub-skill via Task)
• Adapt embed format to detected platform (MDX vs markdown vs HTML)

4h. Add Video Embeds

If the post lacks YouTube video embeds:

• Search 2-3 relevant videos using quality criteria from references/video-embeds.md
• Embed using platform-appropriate format (srcdoc lazy loading)
• Place: 1 after introduction, 1-2 in mid-article sections
• Include noscript fallback for AI crawlers

4i. Add/Improve FAQ

• If no FAQ exists, add one (3-5 questions)
• If FAQ exists, ensure answers are 40-60 words with statistics
• Add FAQ schema markup appropriate to platform

4j. Reduce Self-Promotion

• Max 1 brand mention (author bio context only)
• Remove "At [Company], we..." patterns
• Convert promotional sections to educational content

4k. Citation Capsule Injection

For each H2 section, generate (or improve existing) a citation capsule:

• 40-60 word self-contained passage per H2
• Contains: one specific claim + one data point + source attribution
• Written in a declarative style so an AI system could extract and quote it directly
• Placed naturally within the section body, not as a separate callout

Example:

According to a 2026 Gartner study, 58% of enterprise buyers now consult AI
assistants before contacting a vendor ([Gartner](https://www.gartner.com), 2026).
This shift means B2B content must answer specific questions concisely enough
for AI systems to extract and cite in their responses.

Capsules map to the "AI Citation Readiness" category (15 points) in references/quality-scoring.md.

4l. Anti-AI-Detection Patterns

Apply these transformations to reduce AI-detectable writing patterns:

• Eliminate em dashes - Replace every em dash (-) with a comma, hyphen (-), colon, or period. Split sentences if needed. Em dashes are an AI writing tell.
• Replace flagged phrases - Swap every detected AI phrase (from the scan in Phase 1 step 3) with a natural alternative. Examples:
  • "it's important to note" -> "worth noting" or "keep in mind"
  • "in today's digital landscape" -> "right now" or "in [specific year]"
  • "leverage" -> "use", "apply", "take advantage of"
  • "delve" -> "look at", "explore", "dig into"
  • "robust" -> "strong", "solid", "reliable"
  • "crucial" -> "key", "essential", "critical" (or restructure the sentence)
• Vary sentence length deliberately - After rewriting, scan each paragraph. Inject short punchy sentences (5-10 words) between longer ones (18-25 words). Target: no more than 3 consecutive sentences within 5 words of each other's length.
• Inject rhetorical questions - Add at least one rhetorical question every 200-300 words to break up declarative monotony.
• Use contractions naturally - Replace formal constructions with contractions where they sound natural: "it is" -> "it's", "we have" -> "we've", "do not" -> "don't", "is not" -> "isn't".
• Include hedging language - Sprinkle first-person hedges that signal real experience: "in our experience", "we've found that", "from what we've seen", "this tends to", "it depends on".

4m. Summary Box (Key Takeaways)

If the post lacks a summary box, add one immediately after the introduction:

> **Key Takeaways**
> - [Core finding with statistic and source]
> - [Second key insight or recommendation]
> - [Third actionable takeaway]
> (3-5 bullets, 40-60 words combined. Self-contained - reader gets
> the core value without reading the full article.)

Default label is "Key Takeaways", but this is configurable per persona or brand voice (e.g., "The Bottom Line", "Quick Summary", "What You Need to Know").

If an existing TL;DR box is present, convert it to the bullet-point Key Takeaways format. Verify it meets the 40-60 word requirement and contains at least one statistic with source attribution.

4n. Information Gain Marker Injection

Review the post for original value and tag it:

• [ORIGINAL DATA] - Any proprietary data, survey results, experiments, or case study metrics the author collected first-hand
• [PERSONAL EXPERIENCE] - First-hand observations, lessons learned
• [UNIQUE INSIGHT] - Novel analysis, contrarian perspectives backed by data

If the post lacks original value markers:

• Ask the author for first-hand data or experience to include
• At minimum, add analytical insights that connect existing research in new ways
• Target: at least 2-3 markers per post

Use HTML comments (<!-- [ORIGINAL DATA] -->) or visible callouts depending on the post's style.

Phase 5: Verification

After rewriting, verify all quality gates pass:

Core Quality Gates

1. Every H2 opens with a statistic + source
2. No paragraph exceeds 150 words
3. Zero fabricated statistics
4. Heading hierarchy is clean
5. FAQ section present with schema

10. At least 2-3 information gain markers present
11. Citation capsules in major H2 sections (40-60 words, self-contained)
12. Internal linking zones marked or actual links present (5-10 per 2,000 words)
13. No AI-detectable phrases remain from banned list

Burstiness and Naturalness Check

14. Sentence length variance: SD > 6 (mix of short and long sentences)
15. Contractions used naturally throughout
16. Rhetorical questions present (1 per 200-300 words)
17. AI content estimate reduced from audit baseline
