# SEOAIO.ai > The Website Visibility Operating System. SEOAIO measures how AI engines see a > brand - by running real prompts against real engines and counting the citations > those engines return - and turns measured signals into a prioritized, > evidence-backed action plan. ## What SEOAIO is An AI-visibility (Answer Engine Optimization / GEO) and SEO measurement platform. Its north-star metric is Answer Share. Operated by Combo Ventures LLC. ## How SEOAIO measures (measure, never manufacture) - On-page AI readiness (AEO) is measured directly from a page's server HTML and structured data - not estimated from third-party proxies. - Citations are measured by live sampling: real prompts, run against real engines, counting only the sources the engine itself returned. Nothing is inferred or seeded. - Citation engines measured today: Google AI Mode, Perplexity, ChatGPT, Claude. SEOAIO does not claim to measure engines it has not shipped, and an engine that was not sampled renders as NOT MEASURED rather than as a zero. - Every number is stamped with provenance: measured, estimated, or derived. Aggregate metrics stay "Mixed" until each engine is actually measured. - Every reported share carries a 95% Wilson score interval, so a percentage from a small sample is visibly less certain than the same percentage from a large one. - Run-over-run change is gated by a significance test (Fisher's exact). A movement inside the noise is reported as "cannot tell yet", never as a win. - No ranking or citation outcome is promised. Engines decide what they retrieve and cite, so SEOAIO measures, recommends and drafts, and never sells the outcome itself. ## Plans and pricing Prices are per month unless stated. Engine coverage is the axis a buyer climbs; the top tier differentiates on SCALE (sites, limits, white-label, team access), never on an exclusive engine. - Free: $0 | citation engines: none (no paid engine calls) | Structural and crawler pillars, no engine cost. - Starter: $99/month; annual $89/month billed $1,071/year | citation engines: Perplexity, Google AI Mode | Citations measured on Perplexity and Google AI Mode. - Pro: $249/month; annual $224/month billed $2,691/year | citation engines: Perplexity, Google AI Mode, ChatGPT, Claude | Every measured engine and the full evidence trail. - Agency: $549/month; annual $494/month billed $5,931/year | citation engines: Perplexity, Google AI Mode, ChatGPT, Claude | White-label client reporting at portfolio scale. - Full comparison: https://seoaio.ai/pricing ## Name SEOAIO, also written SEOAIO.ai, at https://seoaio.ai. Tagline: the Website Visibility Operating System. A measurement-first AI-visibility platform; what sets it apart is measurement integrity, with measured-vs-modeled provenance on every metric. ## Key facts - Category: AI visibility / Answer Engine Optimization (AEO, GEO) and SEO - Citation engines measured: Google AI Mode, Perplexity, ChatGPT, Claude - North-star metric: Answer Share, reported with its confidence interval - Differentiator: measurement integrity - measured, never manufactured - Free tool: a no-login AI Search Visibility audit at https://seoaio.ai/audit ## What an agent can do here, and what it cannot Read tools: get_answer_share, get_citation_metrics, get_crawler_activity, get_measurement_status, get_visibility_score, list_assets, list_cited_passages, list_competitors, list_findings, list_prompt_outcomes, list_recommendations and list_sources. The only writes are propose_competitor, propose_fact, propose_measurement, propose_prompt and propose_remove_competitor, and every one of them queues a change request for a human to approve rather than changing anything. Nothing here sends email, charges a card, edits your site, or spends money on an engine call. Start by reading the skill at https://seoaio.ai/SKILL.md; it carries the tool order and the rules for quoting a number. For the measured brief, read https://seoaio.ai/report/SKILL.md. Do not invent a rank, a citation or a competitor: when a tool returns nothing, nothing was measured. No tool starts a run, reads history, or subscribes to anything; propose_measurement only queues a request for a human. Do not invent a tool name: the list from tools/list is complete. ## MCP - URL: https://app.seoaio.ai/api/mcp - Transport: streamable-http, JSON-RPC over POST - Discovery: [server card](https://seoaio.ai/.well-known/mcp/server-card.json) - Auth: OAuth 2.1 with PKCE, metadata at https://app.seoaio.ai/.well-known/oauth-authorization-server, protected resource at https://app.seoaio.ai/.well-known/oauth-protected-resource; or a SEOAIO API key as a Bearer token. The first call without a token answers 401, which is how a client starts OAuth. - Call order: list_assets, then get_measurement_status, then the read tools. A propose_* tool only for a change the user asked for, and it queues a request for a human. - State: get_measurement_status carries the age of each snapshot, the jobs in flight and the proposals already awaiting approval. A null block there is not measured, never zero. - Tools, one page each: - [get_answer_share](https://seoaio.ai/docs/tools/get_answer_share) - [get_citation_metrics](https://seoaio.ai/docs/tools/get_citation_metrics) - [get_crawler_activity](https://seoaio.ai/docs/tools/get_crawler_activity) - [get_measurement_status](https://seoaio.ai/docs/tools/get_measurement_status) - [get_visibility_score](https://seoaio.ai/docs/tools/get_visibility_score) - [list_assets](https://seoaio.ai/docs/tools/list_assets) - [list_cited_passages](https://seoaio.ai/docs/tools/list_cited_passages) - [list_competitors](https://seoaio.ai/docs/tools/list_competitors) - [list_findings](https://seoaio.ai/docs/tools/list_findings) - [list_prompt_outcomes](https://seoaio.ai/docs/tools/list_prompt_outcomes) - [list_recommendations](https://seoaio.ai/docs/tools/list_recommendations) - [list_sources](https://seoaio.ai/docs/tools/list_sources) - [propose_competitor](https://seoaio.ai/docs/tools/propose_competitor) - [propose_fact](https://seoaio.ai/docs/tools/propose_fact) - [propose_measurement](https://seoaio.ai/docs/tools/propose_measurement) - [propose_prompt](https://seoaio.ai/docs/tools/propose_prompt) - [propose_remove_competitor](https://seoaio.ai/docs/tools/propose_remove_competitor) - Skills: [SEOAIO: set up and read a brand's measured AI visibility](https://seoaio.ai/SKILL.md), [SEOAIO: the measured brief](https://seoaio.ai/report/SKILL.md), [SEOAIO: the fix loop](https://seoaio.ai/fix-loop/SKILL.md), [SEOAIO: pages for the questions you lose](https://seoaio.ai/content/SKILL.md), [index](https://seoaio.ai/.well-known/agent-skills/index.json) - Troubleshooting, every message quoted from the code that sends it: [troubleshooting](https://seoaio.ai/docs/troubleshooting) - Docs for humans: [overview](https://seoaio.ai/docs), [get started](https://seoaio.ai/docs/get-started), [auth](https://seoaio.ai/docs/auth), [skills](https://seoaio.ai/docs/skills), [connect MCP](https://seoaio.ai/docs/mcp) - Every docs page is also markdown: append /md to its path, or ask the page itself for text/markdown.
