SEO Audit Bot

A comprehensive SEO auditing skill that analyzes any website and produces a detailed, actionable report.

What It Does

When a user provides a URL, this skill performs a full SEO audit covering:

  1. Technical SEO — robots.txt, sitemap, HTTPS, mobile-friendliness, page speed signals
  2. On-Page SEO — title tags, meta descriptions, headings, URL structure, internal linking
  3. Content Analysis — word count, keyword density, readability, duplicate content signals
  4. Performance — page load indicators, Core Web Vitals signals
  5. Social & Sharing — Open Graph tags, Twitter Cards, structured data
  6. Competitor Comparison (optional) — compare against a competitor URL

How to Use

Basic Audit

User says: "Audit the SEO of https://example.com"

Agent should:

  1. Fetch the target URL using web_fetch
  2. Fetch the robots.txt (/robots.txt)
  3. Fetch the sitemap (/sitemap.xml or from robots.txt)
  4. Analyze the HTML content for all SEO factors
  5. Generate a structured report

Competitor Comparison

User says: "Compare SEO of https://example.com vs https://competitor.com"

Agent should:

  1. Audit both URLs
  2. Generate a side-by-side comparison
  3. 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

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