What is a GEO Audit?

By Antonia Sevilla · Founder of HoldThatLast updated June 2026
Short answer
A GEO audit measures how AI engines perceive, access, and cite your brand across five distinct layers — technical access, semantic understanding, entity & trust, AI answer-surface presence, and business impact — and produces evidence for every claim.

What is a GEO audit?

A GEO audit is a structured measurement of how AI engines perceive, access, and cite your brand. It evaluates the conditions that determine whether your brand can show up inside an AI-generated answer — and produces evidence for every finding, so the results can be re-run and challenged.

What a GEO audit measures

HoldThat structures every audit around five separate layers. They are scored independently and never collapsed into a single number:

  1. Technical Access — can AI crawlers reach and render your content.
  2. Semantic Understanding — is your content structured around the questions buyers actually ask.
  3. Entity & Trust — is your brand a recognized entity with credible third-party signals.
  4. AI Answer-Surface Presence — do real prompts surface your brand inside real AI answers.
  5. Business Impact — is AI-driven discovery translating into measurable downstream outcomes.

See the full model on the AI Visibility Score page.

What evidence gets collected

Every claim a GEO audit makes is backed by a record. HoldThat's evidence model includes:

  • Per-engine prompt runs with timestamp, prompt text, and full answer capture.
  • Citation status (cited, partial, not cited) and position per engine.
  • Competitor citation comparison on the same prompt set.
  • Technical access logs per crawler (GPTBot, PerplexityBot, Google-Extended, ClaudeBot, CCBot).
  • Schema and structured-data validation output per page type.
  • Entity-graph mapping and third-party citation inventory.

When a business needs a GEO audit

You likely need a GEO audit if any of the following are true:

  • Buyers in your category are increasingly starting research inside AI engines.
  • You suspect competitors are being cited in AI answers and you are not.
  • Your traditional SEO is healthy but pipeline from organic discovery is shifting.
  • You want evidence — not vibes — before investing in AI visibility work.

How to start

The lowest-friction starting point is the free teardown: one real prompt against your category, one competitor comparison, delivered as a short Loom in roughly 48 hours. If the gap is real, the full GEO Audit takes it from a sample prompt to a complete measurement across five layers and five engines.
