SEO Content Audit
Skill Purpose
Perform a comprehensive SEO audit of a webpage or website, covering on-page SEO, content quality (E-E-A-T), keyword analysis, technical SEO, and content strategy. This skill combines automated analysis via scripts/analyze_page.py with expert-level manual review to produce an actionable SEO audit document.
When to Use
- User provides a URL and asks for SEO analysis, audit, or recommendations
- User wants to improve organic search rankings and traffic
- User asks about on-page SEO, meta tags, content quality, or technical SEO
- User wants a content gap analysis or content strategy recommendations
- Triggered by
/market seo <url> or /market seo
How to Execute
Step 1: Run Automated Analysis
Use the Python analysis script to gather baseline data:
python3 scripts/analyze_page.py <url>
This script extracts:
- Title tag and meta description
- Open Graph tags
- Heading hierarchy (H1-H6)
- Links (internal and external)
- Images and alt text status
- Forms and CTAs
- Schema/structured data
- Social links
- Tracking scripts
- Viewport meta tag (mobile-friendliness indicator)
- Canonical tag
- Robots meta directives
Capture the JSON output and use it as the foundation for the manual analysis.
Step 2: On-Page SEO Checklist
Evaluate each element and score it as Pass, Needs Work, or Fail.
Title Tag
| Criteria | Best Practice | Check |
|---|
| Exists | Every page must have a unique title tag | Pass/Fail |
| Length | 50-60 characters (displays fully in SERPs) | Pass/Needs Work/Fail |

Step 3: Content Quality Assessment (E-E-A-T)
Evaluate the content against Google's E-E-A-T framework:
Experience
Does the content demonstrate first-hand experience with the topic?
Check for:
- Personal anecdotes, case studies, or real-world examples
- Screenshots, photos, or evidence of hands-on experience
- Specific details that only someone with experience would know
- "I did X and here's what happened" type content
Score: Strong / Present / Weak / Missing
Expertise
Does the author have demonstrated knowledge in this subject?
Check for:
- Author bio with relevant credentials
- Depth of content (not superficial)
- Accurate information and data
- Proper use of industry terminology
- Links to authoritative sources
Score: Strong / Present / Weak / Missing
Authoritativeness
Is the website and author recognized as an authority on this topic?
Check for:
- Author bylines with real names and bios
- About page with company background
- Industry awards or certifications
- Backlinks from authoritative sites
- Media mentions or press coverage
- Guest posts on industry publications
Score: Strong / Present / Weak / Missing
Trustworthiness
Can users trust this content and this website?
Check for:
- HTTPS (SSL certificate)
- Privacy policy and terms of service
- Physical address and contact information
- Customer reviews and testimonials
- Security badges and certifications
- Transparent business practices
- Accurate, up-to-date information
- Properly sourced claims and statistics
Score: Strong / Present / Weak / Missing
Step 4: Keyword Analysis
Primary Keyword Assessment
| Element | Evaluation |
|---|
| Primary keyword identified | What keyword is this page targeting? |
| Search intent alignment | Does the content match what searchers expect? (informational, commercial, transactional, navigational) |
| Keyword in title | Present, position, natural usage |
| Keyword in H1 | Present, natural usage |
| Keyword in first 100 words | Appears early in the content |
| Keyword in subheadings | Appears in at least one H2 or H3 |
| Keyword in meta description | Present and natural |
| Keyword in URL | Present |
| Keyword density | 1-2% is ideal. Over 3% is keyword stuffing. |
Secondary Keywords
Identify 5-10 related keywords that should be naturally included in the content:
- Synonyms and variations of the primary keyword
- Long-tail variations
- Related questions (People Also Ask)
- LSI (Latent Semantic Indexing) keywords
Search Intent Analysis
Determine the search intent behind the target keyword and evaluate if the content matches:
| Intent Type | User Goal | Content Should Be |
|---|
| Informational | Learn something | Blog post, guide, tutorial, FAQ |
| Commercial | Compare options | Comparison page, review, list |
| Transactional | Buy something | Product page, pricing page, checkout |
| Navigational | Find a specific page | Homepage, login page, specific tool |
Misalignment is a ranking killer. If the user searches "how to do X" (informational) and lands on a sales page (transactional), they bounce -- and Google notices.
Step 5: Technical SEO Quick Check
Robots.txt
Check: Does /robots.txt exist and is it properly configured?
XML Sitemap
Check: Does /sitemap.xml exist?
Canonical Tags
Page Speed
Reference benchmarks:
| Metric | Good | Needs Work | Poor |
|---|
| Largest Contentful Paint (LCP) | Under 2.5s | 2.5-4.0s | Over 4.0s |
| First Input Delay (FID) | Under 100ms | 100-300ms | Over 300ms |
| Cumulative Layout Shift (CLS) | Under 0.1 | 0.1-0.25 | Over 0.25 |
| Time to First Byte (TTFB) | Under 200ms | 200-500ms | Over 500ms |
| First Contentful Paint (FCP) | Under 1.8s | 1.8-3.0s | Over 3.0s |
Common speed issues to flag:
- Unoptimized images (recommend WebP format, compression)
- Render-blocking JavaScript or CSS
- No browser caching headers
- No CDN detected
- Excessive third-party scripts (tracking, widgets, fonts)
- Unminified CSS and JavaScript
- Missing compression (gzip or brotli)
Mobile-Friendliness
Step 6: Content Gap Analysis
Methodology for identifying content gaps:
- Identify the topic cluster: What is the main topic this page/site covers?
- Map existing content: What subtopics are already covered?
- Identify missing subtopics: What related topics are competitors covering that this site is not?
- Analyze People Also Ask: What questions do searchers have about this topic?
- Check related searches: What does Google suggest at the bottom of the SERP?
Content Gap Template:
| Missing Topic | Search Volume Potential | Competition | Content Type Needed | Priority |
|---|
| [Topic] | High/Med/Low | High/Med/Low | Blog/Guide/Tool/Page | 1-5 |
Step 7: Featured Snippet Optimization
Identify opportunities to capture featured snippets:
Types of featured snippets:
- Paragraph snippet -- Answer in 40-60 words. Use a clear question as H2/H3 followed by a concise answer.
- List snippet -- Use ordered or unordered lists with H2 containing the target query.
- Table snippet -- Use HTML tables with clear headers.
- Video snippet -- Include video with descriptive title and timestamps.
Optimization checklist:
Step 8: Schema Markup Audit
Check for structured data implementation:
| Schema Type | Applicable To | Status |
|---|
| Organization | Homepage, About page | Present/Missing |
| LocalBusiness | Local businesses | Present/Missing/N/A |
| Product | Product pages | Present/Missing/N/A |
| Article | Blog posts, news | Present/Missing/N/A |
| FAQ | FAQ sections | Present/Missing |
| HowTo | Tutorial content | Present/Missing/N/A |
| Review/AggregateRating | Reviews, testimonials | Present/Missing/N/A |
| BreadcrumbList | All pages with breadcrumbs | Present/Missing |
| WebSite/SearchAction | Homepage (sitelinks search box) | Present/Missing |
| Event | Event pages | Present/Missing/N/A |
Implementation guidance:
- Use JSON-LD format (Google's preferred format)
- Validate with Google's Rich Results Test
- Don't mark up content that isn't visible on the page
- Keep schema data consistent with on-page content
Step 9: Internal Linking Opportunities
Identify specific internal linking improvements:
- Orphan pages -- Pages with no internal links pointing to them
- Hub pages -- High-authority pages that should link to related content
- Topical clusters -- Group related content and create linking structures
- CTA links -- Blog content should link to relevant product/service pages
- Footer/sidebar links -- Sitewide links to important pages
Linking Architecture Assessment:
Homepage
|-- Category/Service Pages (Pillar Content)
|-- Individual Blog Posts/Articles (Cluster Content)
|-- Back-links to Pillar Content
|-- Key Conversion Pages (Pricing, Signup, Contact)
|-- Linked from relevant content
Step 10: Core Web Vitals Impact Assessment
Evaluate the revenue impact of Core Web Vitals performance:
Research-backed impacts:
- Sites passing all Core Web Vitals see 24% fewer page abandonments
- A 100ms decrease in LCP correlates with a 1.1% increase in conversion rates
- Reducing CLS by 0.1 corresponds to a 15% decrease in bounce rate
- Pages loading within 2 seconds have an average bounce rate of 9%, while pages loading in 5 seconds have a 38% bounce rate
Recommendations by metric:
| Metric | If Failing | Typical Fixes |
|---|
| LCP | Over 2.5s | Optimize hero image, preload critical resources, use CDN, reduce server response time |
| FID/INP | Over 100ms | Reduce JavaScript execution, defer non-critical scripts, use web workers |
| CLS | Over 0.1 | Set image dimensions, reserve space for ads/embeds, avoid inserting content above existing content |
Step 11: Blog and Content Strategy Recommendations
Based on the audit findings, recommend:
- Publishing cadence -- How often to publish based on competition and resources
- Content types -- Blog posts, guides, tools, videos, infographics
- Keyword targeting strategy -- Balance between high-volume and long-tail
- Content length -- Benchmark against top-ranking content for target keywords
- Content update strategy -- How often to refresh existing content
- Distribution plan -- How to promote content beyond organic search
Content Prioritization Matrix:
| Content Idea | Search Volume | Competition | Business Value | Priority Score |
|---|
| [Topic] | High/Med/Low | High/Med/Low | High/Med/Low | 1-10 |
Scoring: High volume + Low competition + High business value = Highest priority

Key Principles
- SEO audits should be educational, not just diagnostic. Explain WHY each element matters so the client understands the value.
- Always provide the "before" (current state) and "after" (recommended change) so the client can see exactly what needs to change.
- Tie SEO improvements to business outcomes. "Optimizing your title tag" means nothing to a business owner. "Optimizing your title tag could increase your click-through rate by 20-35%, bringing an estimated 500 more visitors per month to this page" is actionable.
- Use the automated script data as a starting point, but add expert analysis on top. The script finds the data; the skill interprets what it means.
- Prioritize recommendations by effort-to-impact ratio. A title tag change takes 5 minutes but can impact every search impression. A full content rewrite takes weeks.
- If the user has run
/market audit or /market landing previously, cross-reference those findings with the SEO audit for a more complete picture.
