AI Visibility

Definition: AI Visibility is the degree to which your content is recognized, selected, and reused by AI systems (e.g., AI Overviews, Copilot/Copilot Search, Perplexity, chat assistants) when generating answers, summaries, or recommendations.

Scope:

• Includes: recognition of your content as a credible reference; selection and reuse in AI-generated answers; signals that make content easy for AI to parse, summarize, and attribute.
• Excludes: traditional rankings as a proxy for visibility; traffic metrics that do not reflect presence in AI-mediated results.
• Notes: A page may perform well in search while remaining invisible to generative systems. AI visibility depends on semantic clarity, entity grounding, and perceived trustworthiness.

Why it matters: As discovery shifts from “lists of links” to “direct answers,” consideration increasingly happens inside AI experiences. AI Visibility determines whether your brand is present—and attributable—at that decisive moment.
