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 .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Before auditing, understand:
Site Context
- What type of site? (SaaS, e-commerce, blog, etc.)
- What's the primary business goal for SEO?
- What keywords/topics are priorities?
Current State
- Any known issues or concerns?
- Current organic traffic level?
- Recent changes or migrations?
Scope
- Full site audit or specific pages?
- Technical + on-page, or one focus area?
- Access to Search Console / analytics?
