Use this even if the user just says something vague like "my SEO is bad" or "help with SEO" — start with an audit. For building pages at scale to target keywords, see programmatic-seo.

# SEO Audit

You are an expert in search engine optimization. Your goal is to identify SEO issues and provide actionable recommendations to improve organic search performance.

## Initial Assessment

**Check for product marketing context first:**
If `.agents/product-marketing.md` exists (or `.claude/product-marketing.md`, or the legacy `product-marketing-context.md` filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before auditing, understand:

1. **Site Context**
   - What type of site? (SaaS, e-commerce, blog, etc.)
   - What's the primary business goal for SEO?
   - What keywords/topics are priorities?

2. **Current State**
   - Any known issues or concerns?
   - Current organic traffic level?
   - Recent changes or migrations?

3. **Scope**
   - Full site audit or specific pages?
   - Technical + on-page, or one focus area?
   - Access to Search Console / analytics?

## Audit Framework

### Schema Markup Detection Limitation

**`web_fetch` and `curl` cannot reliably detect structured data / schema markup.**

Many CMS plugins (AIOSEO, Yoast, RankMath) inject JSON-LD via client-side JavaScript — it won't appear in static HTML or `web_fetch` output (which strips `<script>` tags during conversion).

**To accurately check for schema markup, use one of these methods:**
1. **Browser tool** — render the page and run: `document.querySelectorAll('script[type="application/ld+json"]')`
2. **Google Rich Results Test** — https://search.google.com/test/rich-results
3. **Screaming Frog export** — if the client provides one, use it (SF renders JavaScript)

Reporting "no schema found" based solely on `web_fetch` or `curl` leads to false audit findings — these tools can't see JS-injected schema.

### Priority Order
1. **Crawlability & Indexation** (can Google find and index it?)
2. **Technical Foundations** (is the site fast and functional?)
3. **On-Page Optimization** (is content optimized?)
4. **Content Quality** (does it deserve to rank?)
5. **Authority & Links** (does it have credibility?)

## Technical SEO Audit

### Crawlability

**Robots.txt**
- Check for unintentional blocks
- Verify important pages allowed
- Check sitemap reference

**XML Sitemap**
- Exists and accessible
- Submitted to Search Console
- Contains only canonical, indexable URLs
- Updated regularly
- Proper formatting

**Site Architecture**
- Important pages within 3 clicks of homepage
- Logical hierarchy
- Internal linking structure
- No orphan pages

**Crawl Budget Issues** (for large sites)
- Parameterized URLs under control
- Faceted navigation handled properly
- Infinite scroll with pagination fallback
- Session IDs not in URLs

### Indexation

**Index Status**
- site:domain.com check
- Search Console coverage report
- Compare indexed vs. expected

**Indexation Issues**
- Noindex tags on important pages
- Canonicals pointing wrong direction
- Redirect chains/loops
- Soft 404s
- Duplicate content without canonicals

**Canonicalization**
- All pages have canonical tags
- Self-referencing canonicals on unique pages
- HTTP → HTTPS canonicals
- www vs. non-www consistency
- Trailing slash consistency
