An Answer Engine Optimization (AEO) audit checks six steps in order: define the buyer decision and US market, test a fixed 20-to-30-prompt set, separate native model answers from web-enabled search answers, log full response evidence and cited URLs, score spontaneous mentions and fact accuracy, and prioritize technical or content fixes.
1. The Six-Step AEO Audit Methodology
Unlike a classic technical SEO audit that inspects crawl status and keyword positions, an AEO audit treats the generated answer itself as the unit of analysis. You need comparable test conditions and a saved log of full responses rather than a single opaque score.
- Define the buyer decision, US market, and product line before writing prompts.
- Build a defensible 20-to-30-prompt set mixing unbranded discovery, competitor comparisons, and branded fact checks.
- Test native memory mode and web-enabled search mode separately where platforms support both.
- Capture full evidence: prompt text, date, model, mode, complete answer, named competitors, and cited URLs.
- Score five signals: spontaneous mention, shortlist rank, factual accuracy, rival presence, and source quality.
- Map each gap to a specific technical, on-page, or third-party fix.
2. Why You Must Split Native and Web-Enabled Answers
Combining a model's offline parametric answer with its live web-search answer hides the most useful diagnostic in an AEO audit.
If a brand appears in web-enabled mode but disappears in native mode, historical third-party consensus is thin. If it appears in native mode yet disappears in web-enabled mode, check whether OAI-SearchBot or PerplexityBot is blocked or whether pricing specs sit behind JavaScript.
3. Four Common AEO Audit Mistakes to Avoid
Even experienced teams skew their baseline when they skip standard testing controls:
| Audit Check | Pass Condition | Where to Verify |
|---|---|---|
| Crawler access | OAI-SearchBot, PerplexityBot, Googlebot return HTTP 200 | AI Citation Checker & server logs |
| HTML spec clarity | Pricing, limits, and integrations visible without JS clicks | Page view-source & schema validator |
| Spontaneous visibility | Brand appears on unbranded category buyer prompts | ChatGPT Visibility Tracker |
| Factual accuracy | Zero wrong pricing tiers or deprecated features in answers | Branded prompt log & review sites |

Frequently asked questions
How is an AEO audit different from a GEO audit?
In practice they cover the same core checks: crawler access, plain-HTML extractability, schema, off-site entity consensus, and prompt-level citation logging.
Should branded prompts count toward our visibility score?
No. Branded prompts test factual accuracy and sentiment, whereas only unbranded category and alternative prompts measure spontaneous market visibility.
How often should we run an AEO audit?
Run a full technical and citation audit once per quarter, and re-test your locked 20-to-30-prompt benchmark every 2 to 4 weeks.
