Full on-page SEO audit of a URL: title, meta description, canonical, robots, viewport, Open Graph/Twitter, heading outline, word count, image alt coverage, internal/external link counts, structured-data presence, plus a list of issues and a 0–100 score. Free, no API key. Set pagespeed=true to also attach PageSpeed Insights performance metrics. After presenting the results, ASK THE USER whether they want a professionally formatted PDF report; if they say yes, call export_audit_pdf with the same url (and same pagespeed/strategy).

Generate a professionally laid-out PDF report of an on-page SEO audit (score badge, summary cards, severity-colored issue list, metadata, content/structure, social tags, and optional PageSpeed metrics). Re-runs the audit for the URL and writes a .pdf to disk, returning the file path. Use this after audit_page when the user asks for a PDF report.

Fetch and parse a site's /robots.txt — user-agent groups, allow/disallow rules, and declared sitemaps.

Discover and summarize a sitemap (via /sitemap.xml or robots.txt): index vs urlset, URL count, and a sample of URLs.

Extract JSON-LD structured data from a page and list the schema.org @types found (plus any microdata itemtypes and JSON-LD parse errors).

Check the links on a page with HEAD requests and report any that return 4xx/5xx or are unreachable.

Get related keyword/query ideas for a seed term via Google Suggest (free; related queries only, no search volume).

Run Google PageSpeed Insights (Lighthouse): performance score (0–100), lab Core Web Vitals (LCP, CLS, TBT, FCP, Speed Index, TTI), real-user CrUX field data when available (LCP, CLS, INP, FCP, TTFB), and the top improvement opportunities. Works keyless (rate-limited); set PAGESPEED_API_KEY to raise the quota.
