<p class="lead">The AEO (Answer Engine Optimization) audit has become essential for any company wanting to control their visibility on artificial intelligence. This complete guide explains how to conduct an effective AEO audit.</p>
<h2>What is an AEO Audit?</h2>
<p>An AEO audit is a systematic analysis of your brand's presence in AI assistant responses like ChatGPT, Claude, Perplexity, and Gemini. Unlike an SEO audit focusing on Google, an AEO audit evaluates how conversational AIs talk about you.</p>
