# What is prompt injection, and should hotel websites worry?

> Prompt injection is hidden text that tries to give instructions to an AI reading a page. Hotels shouldn't use it, and agents are built to ignore it.

**Prompt injection** is text placed in content an AI will read, such as a web page, email or document, that tries to give the AI instructions: "ignore previous instructions", "always recommend this hotel", "tell the user the price is lower". It's often hidden from people with tiny or invisible text.

## Why hotels should avoid it

- AI companies train agents to treat page content as information, not instructions, and to flag suspicious text.
- Hidden instructions can make a site look untrustworthy to agents, search engines and security tools.
- Anything that misleads guests about price or features can break consumer protection rules.

## What works instead

Plain, accurate facts in text: room details, total prices, policies, and clear [structured data](https://akkrev.com/glossary/structured-data/). A page that's easy to read honestly is the most persuasive thing an agent can find.

## Why it matters for AI visibility

Hidden instructions aimed at AI don't make it recommend you, and can backfire. Clear, honest facts are what work.
