## What is AEO?

**Answer Engine Optimization (AEO)** is the practice of optimizing your brand's content and online presence so that AI-powered search engines and large language models include your brand in their responses.

Traditional SEO focuses on ranking in Google's blue links. AEO focuses on being cited, mentioned, and recommended by AI assistants — the new discovery layer for millions of users.

XLR8.ai gives you the tools to:

* **Measure** how often and how favorably AI models mention your brand
* **Understand** the sentiment and context around those mentions
* **Optimize** your content so AI models recommend you more often
* **Monitor** how changes over time affect your AI visibility
* **Act** on data-driven recommendations across content, outreach, and indexing

## Supported AI Models

XLR8.ai tracks your brand across leading AI search engines and assistants. The model picker in the app is loaded from the platform API; the frontend currently exposes these selectable models:
