Crawl a website and fetch its Ahrefs SEO metrics. Returns a JSON object with: crawl (pages, issues, schema summary), ahrefs (DR, keywords, traffic, backlinks, top pages, referring domains), brand_name (inferred from schema/title), and industry (inferred from page content). Call this first when auditing a site.

Measure how often a brand appears in AI/answer-engine results for unbiased, category-level buyer queries. Generates prompts (brand-name excluded), runs grounded web-search rankings, and returns brand visibility %, average position, per-topic breakdown, and competitor brands. Pass brand and industry from fetch_audit_data when available. Requires OPENAI_API_KEY.

Render the completed SEO/AEO audit report as a PDF file. Pass the ahrefs and crawl objects exactly as returned by fetch_audit_data (pass through unchanged), plus the ai_visibility data you gathered via web search and the narratives you wrote based on the data.
