On-Page SEO + E-E-A-T Optimizer

Analyze and optimize individual pages for search visibility, content quality, and E-E-A-T compliance. Every issue includes a Claude Code fix command. This skill works directly on the user's content files — no external measurement infrastructure required.

Cross-model note

Works identically on current Opus / Sonnet / Haiku models. Per-page rewrites are independent; batch across pages in parallel when auditing multiple pages.

Execution: parallel-first

• Multi-page audits: Reads across pages independent — batch
• Per-page rewrites: each section's audit independent (title, meta, headings, alt text) — batch within a page
• WebFetch for URL-based audit: parallel per URL

4. Content Quality Scoring

Score each page on a 0-100 scale using six dimensions. Each dimension is worth up to ~17 points. A page scoring below 70 needs improvement; below 50 is critical.

Audit Checklist

1. Depth -- Compare word count and subtopics against the top 5 ranking pages.
2. Originality -- Flag if content closely paraphrases competitor pages with no new data.
3. Readability -- Paragraphs > 4 sentences? Missing lists or visuals? Flag them.
4. Intent match -- Identify the keyword's intent (informational, transactional, navigational)

and verify the page format matches.

1. Freshness -- Check for a visible published or "last updated" date. Flag if older than

12 months or missing entirely.

1. Keyword usage -- Calculate keyword density. Flag if < 0.5% (under-optimized) or

2.5% (stuffing).

Fix Commands

# Score a page's content quality
claude "Analyze /src/pages/guide.html for content quality. Score it 0-100 across depth, originality, readability, intent match, freshness, and keyword usage. Show the breakdown and specific improvement actions."

# Fix keyword density
claude "In /src/pages/guide.html, the keyword 'email marketing' appears at 0.3% density. Add 4-6 natural mentions in existing paragraphs to reach 1-1.5% density without stuffing."

# Improve readability
claude "In /src/pages/guide.html, break any paragraph longer than 4 sentences into shorter ones. Add bullet lists where 3+ items are listed in prose."

5. E-E-A-T Assessment

Reference: eeat-checklist.md for the full scoring rubric.

The Four Pillars

and links to professional profiles.

team credentials.

1. Citations -- At least 3 outbound links to authoritative sources per 1,000 words.
2. Dates -- Published and "last updated" dates are visible on every content page.
3. YMYL check -- If the page covers health, finance, legal, or safety topics, apply

heightened standards: medical review, professional credentials, disclaimers.

1. Experience signals -- Look for original photos, screenshots, personal anecdotes,

or case study data that prove first-hand experience.

1. Trust signals -- HTTPS active, privacy policy linked, contact page accessible,

no deceptive ads or popups.

Output a prioritized list of issues with severity (critical/warning/info)."

# Step 2 -- Apply all fixes
claude "Apply every critical and warning fix identified in the audit of /src/pages/target-page.html. Preserve existing content meaning while optimizing structure, meta tags, headings, images, and links."
