What is an iframe (in hotel booking)?
Updated By Akkrev
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 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.
