Reaching AI Visibility L3 + AI Capability L2 already puts you ahead of most websites!

AI Visibility measures how easily AI systems can find, understand, and recommend your website.It evaluates whether your content can be crawled, parsed, and selected as a source when users ask questions in ChatGPT ,Claude, Gemini, and other AI systems. A low Visibility score means: AI either cannot see your content, or sees it but does not choose it.

Basic Accessibility

can AI access your website smoothly?

AI crawling allowed Major AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) are permitted to access your site.

Page content directly readable Main content is visible in the HTML source, not only rendered after JavaScript executes.

Clear title and description The page has a clear title and meta description, helping AI quickly identify the topic.

Reasonable response time The page responds quickly enough to avoid AI crawl failures or timeouts.

HTTPS secured The site uses a valid HTTPS certificate.

Content is not gated Core content isn't blocked by login walls, membership gates, or paywalls.

Content Comprehensibility

can AI understand what your site is about?

Has structured data Uses Schema.org / JSON-LD to help AI understand page content more accurately.

Has social sharing info Open Graph tags provide supplementary title and summary information.

Clear canonical address A canonical URL tells search engines and AI which version of the URL is authoritative.

Clear heading hierarchy The page has a clear H1 and uses H2/H3 headings to organize content logically.

Language declared correctly The HTML lang attribute is set, helping AI identify the page language.

Substantial content The page has meaningful text content, not just a few sentences of boilerplate.

Discoverability

can AI find more of your pages, not just the homepage?

Provides a sitemap An accessible XML sitemap helps AI and search engines discover your pages.

Sitemap stays updated The sitemap includes recent pages and isn't neglected over time.

Clear internal linking Key content pages are easily reachable from the homepage and main pages.

Clean, readable URLs Page URLs clearly reflect the content topic, rather than being cryptic parameter strings.

Provides llms.txt A /llms.txt file proactively tells LLMs which content is most worth paying attention to.

Consistent canonical setup The canonical tag points to the current page's standard address, avoiding duplicate page confusion.

Trust & Authority

will AI trust your site enough to cite it?

Organization info is clear Structured data includes basic info like company/organization name, website, and logo.

About and contact info visible Both users and AI can easily find your contact or about page.

Content source is clear Pages attribute content to an author, team, or organization.

Publication dates are clear Pages include publish or update dates, helping assess content freshness.

Legal info is complete The site has essential pages like privacy policy and terms of service.

Proper security configuration Basic security response headers are set, reflecting site maintenance quality.

AI-Optimized

is your site specifically optimized for AI recommendations?

Has FAQ / HowTo / Q&A structure Page content is structured for AI to directly extract answers.

Has breadcrumb structure Helps AI understand the page's position and hierarchy within the site.

Has review information Products, services, or content include structured Review/Rating data.

Supports multiple languages Multilingual pages have clear corresponding relationships, such as hreflang tags.

Richer structured data Uses multiple effective Schema.org types, not just one.

Clear content block structure Pages contain FAQs, tables, lists, definitions, etc., making it easy for AI to extract and summarize.

AI Capability measures how well your website can be used, integrated, or interacted with by AI systems. It evaluates whether your site provides structured data, APIs, or interfaces that allow AI to retrieve information or perform actions. A low Capability score means: Even if AI wants to use your site, it cannot do so effectively.

Basic Accessibility

can agents reliably read and interpret your public content?

Semantic HTML Uses semantic HTML elements such as header, nav, main, article, section, and footer so agents can better understand page structure.

Metadata Includes essential metadata such as page title, description, and social sharing tags to improve machine interpretation.

Structured Data Provides JSON-LD structured data based on Schema.org to make entities and page meaning more explicit.

No CAPTCHA Barriers Public content is accessible without CAPTCHA or other anti-bot challenges that block legitimate automated access.

Server-Rendered Content Core content is present in the initial HTML response, rather than relying entirely on client-side JavaScript rendering.

Clean URLs Uses stable, human-readable URLs without excessive query parameters, session tokens, or hash-fragment routing.

Discoverability

can agents discover your content, endpoints, and developer surface area?

robots.txt Provides a robots.txt file that permits access for legitimate crawlers and agent systems where appropriate.

XML Sitemap Publishes a valid XML sitemap to help agents and crawlers discover indexable pages efficiently.

llms.txt Exposes a /llms.txt file that gives LLM-based systems guidance on important content and site structure.

OpenAPI Specification Publishes an OpenAPI or Swagger specification so agents can understand available API endpoints programmatically.

Machine-Readable Documentation Provides comprehensive documentation in a format that is easy for machines and agents to parse and use.

Text-Accessible Content Ensures primary content is available as text, rather than being locked inside images, videos, or non-parsable PDFs.

Structured Interaction

can agents interact through predictable, machine-friendly interfaces?

Structured API Exposes a well-defined REST or GraphQL API for programmatic access to data and actions.

Consistent JSON Responses Returns JSON payloads with stable and predictable schemas across endpoints.

Search and Filtering Support Supports query parameters for search, filtering, pagination, and retrieval refinement.

A2A Agent Card Provides an agent descriptor, such as an A2A agent card at /.well-known/agent.json, to advertise agent capabilities.

Documented Rate Limits Clearly documents rate limits and returns proper 429 Too Many Requests responses when limits are exceeded.

Structured Error Handling Returns machine-readable error responses with clear codes, messages, and actionable context.

Agent Integration

can agents move beyond reading and actually perform work on your platform?

MCP Server Provides an MCP (Model Context Protocol) server so agents can access tools, resources, and actions through a standardized interface.

WebMCP Support Supports WebMCP or comparable browser-oriented agent interaction patterns for web-based automation.

Write-Capable API Supports write operations such as POST, PUT, PATCH, and DELETE, enabling agents to create and update resources.

Agent-Friendly Authentication Supports automation-ready authentication methods such as API keys or OAuth client credentials flows.

Webhooks Supports webhooks so agents can receive event-driven updates instead of relying only on polling.

Idempotent Writes Write operations support idempotency keys or equivalent safeguards to prevent duplicate execution.

Autonomous Operation

can agents operate continuously, proactively, and across systems?

Event Streaming Supports real-time update channels such as SSE or WebSockets for low-latency agent workflows.

Capability Negotiation Supports agent-to-agent capability discovery or negotiation so systems can adapt to each other dynamically.

Subscription and Management API Provides APIs for subscription, lifecycle management, or registration of agent integrations.

Workflow Orchestration Supports multi-step workflows, task coordination, and stateful execution across actions or services.

Proactive Notifications Can proactively notify agents when relevant content, state, or business events change.

Cross-Service Handoff Supports handoff between agents or services so tasks can continue across system boundaries.
