# What is an iframe (in hotel booking)?

> An iframe is a web page embedded inside another page. Many hotel booking engines load in an iframe, which can make them harder for AI agents to use.

An **iframe** (inline frame) is a window inside a web page that shows another page, often from another company's domain. Hotels use iframes to place their vendor's [booking engine](https://akkrev.com/glossary/booking-engine/) inside their own site design, so the guest never seems to leave.

## Why it matters for agents

To a person, an iframe looks like part of the page. To an AI agent, it's a separate document, sometimes from a different domain, with its own loading, scrolling and security rules. Agents have improved, but iframes remain a frequent point where they lose track: clicks don't register, content doesn't load, or the agent can't read the prices inside.

## How to tell if your booking engine is in an iframe

On a desktop browser, right-click inside your booking box. If you see an option like "View frame source" or "Reload frame", it's an iframe.

## Why it matters for AI visibility

Content inside iframes is often invisible to AI crawlers, so rooms and prices shown only there may never reach AI answers.
