How to Use
Basic Audit
User says: "Audit the SEO of https://example.com"
Agent should:
- Fetch the target URL using
web_fetch - Fetch the robots.txt (
/robots.txt) - Fetch the sitemap (
/sitemap.xmlor from robots.txt) - Analyze the HTML content for all SEO factors
- Generate a structured report
Competitor Comparison
User says: "Compare SEO of https://example.com vs https://competitor.com"
Agent should:
- Audit both URLs
- Generate a side-by-side comparison
- Highlight advantages and gaps
Audit Process
Step 1: Fetch the Page
web_fetch(url="<target_url>", maxChars=50000, extractMode="text")Step 2: Check Technical Signals
- Fetch
robots.txt→ check if exists, what's blocked - Fetch
sitemap.xml→ check if exists, last modified - Check HTTPS redirect
- Check canonical tag presence
Step 3: Analyze On-Page Elements
Extract and evaluate:
<title>— length (50-60 chars ideal), keyword presence<meta name="description">— length (150-160 chars ideal), keyword presence<h1>— single h1, contains primary keyword<h2>–<h6>— proper hierarchy- URL structure — short, descriptive, keyword-rich
- Image alt tags — descriptive, not keyword-stuffed
- Internal links — count, quality, anchor text
- External links — count, quality, nofollow usage
Step 4: Content Analysis
- Word count (minimum 300 for pages, 1000+ for blog posts)
- Keyword density (1-3% for primary keyword)
- Heading structure (logical hierarchy)
- Readability (sentence length, paragraph size)
- Duplicate content risk
Step 5: Performance Indicators
- Check for
<meta name="viewport">(mobile-friendly) - Check for lazy loading on images
- Check for minified CSS/JS references
- Check for CDN usage
- Check for excessive inline styles
Step 6: Social & Schema
- Open Graph tags (og:title, og:description, og:image)
- Twitter Card tags
- JSON-LD structured data
- Schema.org markup
Step 7: Generate Report

Tips for the Agent
- Be specific — don't just say "improve SEO", say exactly what to change
- Prioritize — label recommendations as HIGH/MEDIUM/LOW
- Show before/after — when suggesting changes, show the current state and the ideal state
- Be honest about limitations — you can't check page speed directly, only indicators
- Offer follow-up — suggest re-audit after changes are made
