SEO Audit Agent Skill

SEO Audit

Audit affiliate blog posts and landing pages for SEO issues — on-page optimization, keyword usage, meta tags, content quality signals, affiliate link attributes, and internal linking. Output is a 10-dimension SEO scorecard with a prioritized fix-it checklist.

Stage

S6: Analytics — 53% of all website traffic comes from organic search. For affiliate bloggers, SEO is the most sustainable traffic source — but most affiliate content has basic SEO mistakes that tank rankings. This skill catches those mistakes and provides quick wins.

When to Use

• User has a blog post or landing page and wants an SEO review
• User asks "why isn't my page ranking?" or "check my SEO"
• User wants to improve search rankings for affiliate content
• User says "SEO audit", "SEO checklist", "on-page optimization"
• User wants to check affiliate link attributes (nofollow, sponsored)
• Chaining from S3 (blog) or S4 (landing): audit content before or after publishing

Input Schema

content: string                # REQUIRED — the content to audit (markdown, HTML, or URL)
                               # If URL, will attempt to fetch and analyze

target_keyword: string         # REQUIRED — primary keyword to optimize for
                               # (e.g., "best AI video tools", "HeyGen review")

content_type: string           # OPTIONAL — "blog_post" | "landing_page"
                               # Default: "blog_post"

competitor_urls:               # OPTIONAL — competitor pages to compare against
  - string                     # e.g., ["competitor.com/heygen-review"]

secondary_keywords:            # OPTIONAL — additional keywords to check
  - string                     # e.g., ["AI video generator", "HeyGen pricing"]

Chaining context: If S3 (blog) or S4 (landing page) was run in the same conversation, pull the generated content directly for audit. The user should not have to paste content just generated.

Workflow

Step 1: Analyze Content Structure

Check:

• Word count: Is it competitive? (blog: 1500+ words, landing: varies)
• Heading structure: H1 present and unique? H2/H3 hierarchy logical?
• Paragraph length: Short paragraphs for readability?
• Content depth: Does it cover the topic comprehensively?

Step 2: Check Keyword Usage

Analyze:

• Title tag: Contains target keyword? Under 60 characters?
• H1: Contains target keyword?
• First 100 words: Keyword appears naturally?
• Keyword density: 1-2% optimal (not stuffing, not absent)
• Keyword in subheadings: At least one H2 contains keyword or variant?
• LSI keywords: Related terms present for topical depth?

Step 3: Evaluate Meta Tags

Check:

• Title tag length: 50-60 characters optimal
• Meta description: Present? 150-160 characters? Contains keyword? Compelling?
• OG tags: Open Graph tags for social sharing
• Canonical URL: Present and correct?

Step 4: Check E-E-A-T Signals

Evaluate:

• Experience: First-person experience with the product?
• Expertise: Author credentials or demonstrated knowledge?
• Authoritativeness: Citing sources, linking to official pages?
• Trustworthiness: Transparent disclosure, balanced (pros AND cons)?

Step 5: Check Affiliate Link Attributes

Verify:

• All affiliate links have rel="nofollow sponsored" (Google requirement)
• Links are not cloaked in a way that violates search guidelines
• FTC disclosure is present and above the fold
• Links open in new tab (target="_blank") for UX

Step 6: Check Internal Linking

Evaluate:

• Links to related content on the same site?
• Anchor text is descriptive (not "click here")?
• Table of contents for long content?

Step 7: Score on 10 Dimensions

Rate each 1-10:

• Keyword optimization
• Content depth and quality
• Title tag and meta description
• Heading structure
• E-E-A-T signals
• Affiliate link compliance
• Internal linking
• Readability and formatting
• Mobile friendliness indicators

Step 8: Generate Fix-It Checklist

Prioritize fixes by impact:

• Quick wins: Fix in 5 minutes, big impact (meta tags, keyword in H1)
• Medium effort: Fix in 30 minutes (add sections, improve depth)
• Major revision: Fix in 2+ hours (restructure content, add original research)

Step 9: Self-Validation

Before presenting output, verify:

• [ ] All 10 SEO dimensions scored (1-10 each)
• [ ] Overall score is weighted sum of dimension scores
• [ ] Issues prioritized: quick_win → medium → major
• [ ] Each fix is specific and actionable (not generic advice)
• [ ] Keyword density recommendation is 1-2% (not higher)

If any check fails, fix the output before delivering. Do not flag the checklist to the user — just ensure the output passes.

• Competitor Comparison — brief notes if competitor URLs were provided

Error Handling

• No content provided: "Paste the content of your blog post or landing page. I'll audit it for SEO issues and give you a prioritized fix-it list."
• No target keyword: "What keyword are you trying to rank for? (e.g., 'HeyGen review', 'best AI video tools'). This helps me check keyword usage and optimization."
• Content is too short (<300 words): "This content is quite short (X words). For competitive keywords, aim for 1,500+ words. I'll audit what's here, but content depth is likely your biggest SEO issue."
• URL provided but cannot be fetched: "I couldn't fetch that URL. Paste the page content directly and I'll audit it."

Examples

Example 1: Blog post with common issues

User: "Audit this blog post for 'best AI video tools': [pastes 2000-word blog post]"

Action: Score each dimension. Common findings: keyword not in H1 (fix: add to title), affiliate links missing rel="nofollow sponsored" (fix: add attributes), no meta description (fix: write one), thin intro section (fix: expand first paragraph). Overall score: 62/100. Quick wins: meta description, H1 keyword, link attributes.

Example 2: Landing page audit

User: "Check the SEO on my HeyGen landing page" [content from S4 in conversation]

Action: Pull landing page content from S4 output. Note: landing pages are typically not SEO-optimized (they're conversion-focused). Score accordingly — different expectations for landing pages vs blog posts. Focus on: title tag, meta description, canonical, affiliate link compliance.

Example 3: Competitive comparison

User: "Audit my Semrush review and compare to these competitor pages: [competitor URLs]"

Action: Audit user's content first. Then use web_search or web_browse to analyze competitor content structure (word count, headings, topics covered). Identify content gaps — topics competitors cover that the user doesn't. Recommend additions to improve competitiveness.
