Check how visible a website is to AI assistants right now. Use this whenever someone asks "does ChatGPT/Perplexity/Claude/Gemini recommend this business," "is my site showing up in AI answers," "what's my AI visibility / GEO score," or wants a quick read on whether an AI assistant would surface a given domain. Returns an overall AI-visibility score (0–100), a per-engine breakdown (ChatGPT, Perplexity, Claude, Gemini), and the top competitor appearing in place of the site. The result also includes trend data: 7- and 30-day score movement computed from the domain's stored snapshot history. Requires an active subscription.

Run a full one-time audit of a website — AI visibility plus SEO, security headers, broken links, and performance. Use this when someone asks to "audit," "scan," "check," or "review" a website's health or SEO, or wants a complete report rather than just the AI-visibility number. Returns a scored summary across categories and a link to the full report. Requires an active subscription.

Report what changed in a website's AI visibility and audit since it was last checked. Use this when someone asks "did anything change," "what's different this week/month," "did my AI visibility drop," or "did a competitor overtake me." Requires the domain to be tracked (see track_site). Returns deltas: score movement, engines gained/lost, competitors that moved, and new or resolved issues.

Compare a website's AI visibility head-to-head against named competitors. Use this when someone asks "how do I stack up against X and Y," "who does ChatGPT recommend instead of me," or wants a competitive AI-visibility view. Returns each competitor's score and where they appear that the site does not. Each competitor not already cached costs one audit against your daily quota; if the quota can't cover every competitor, it ranks the ones it could audit and returns a quota summary plus a skipped list naming the rest — it never drops competitors silently or invents scores. If the quota is already exhausted it returns an over-quota error with the reset time.

Start (or stop) ongoing monitoring of a website's AI visibility on a schedule. Use this when someone wants to "monitor," "track," "watch," or "get alerted about" a site's AI visibility over time, rather than a one-off check. Establishes the history that get_changes reads from.

Benchmark a website's AI visibility against its industry and location. Use this when someone asks "how do I compare to others in my space," "is this a good score for my industry," or wants percentile/peer context rather than an absolute number. Backed by aggregated audit data.

Get specific, prioritized fixes to raise a website's AI visibility and audit scores. Use this when someone asks "how do I fix this," "what should I change," "how do I improve my AI visibility," or after an audit surfaces issues. Returns ranked actions with expected impact.

Generate ready-to-paste structured data (JSON-LD schema) tailored to a website, to improve how AI assistants and search engines understand it. Use this when someone asks for "schema," "structured data," "JSON-LD," or wants the actual markup to implement a recommendation. Returns valid JSON-LD.

Get a shareable report URL and the embeddable "Audited by Website Auditor" badge snippet for a website. Use this when someone wants to "share," "export," "send a client," or "embed" the audit result. Returns a link and an HTML badge snippet.

Stop ongoing monitoring of a website's AI visibility. Use this when someone wants to "stop tracking," "unmonitor," "stop watching," or "remove" a site from scheduled monitoring, or to free up a monitoring slot. Idempotent — safe to call even if the site isn't currently tracked. Returns how many monitoring slots are now free.

List the websites currently being monitored for AI visibility on a schedule. Use this when someone asks "what am I tracking," "which sites am I monitoring," "how many monitoring slots am I using," or wants to see their tracked domains. Returns each tracked domain with its cadence and active state, plus slots used and remaining (out of 5).

Get a glanceable summary of monitoring status across all tracked websites. Use this when someone asks "how are my tracked sites doing," "what's my current AI visibility across everything I monitor," "when were my sites last checked or when do they run next," or wants a dashboard of their monitored domains. Returns, per domain, the latest AI-visibility score, when it was last audited and next runs, and the most recent change since the prior check.

Check the caller's own Website Auditor subscription standing. Use this when someone asks "am I on Pro," "is my trial still active," "when does my subscription renew/end," "why is this tool locked," or before suggesting an upgrade. Works with any valid API key and consumes no audit quota. Returns the tier (none/free/pro), raw subscription status, period end, whether the subscription is set to cancel, the upgrade URL, and a plain-language summary — including what starting Pro requires (a payment method and accepting the Terms).
