> Agent instructions:
> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

The system allows you to check pages for broken links. Only links within ****, ****, **** and **** elements are validated by the link checker.

1. Open the **Pages** application.
2. Select a page in the content tree.
3. Switch to the **Preview** mode.
4. Open the **Validate -> Link checker** tab.
5. Click **Validate**.

If the validator finds broken links on the page, you can view the following information for each detected issue:

- **Status code** - the HTML status code returned when the link is accessed. Statuses of redirected links are shown for each page within the redirection.
- **Type** - W for links redirected to a different location (301 status code), E for broken links (404 status code).
- **Error message** - details about the link issue.
- **URL** - URL to which the link is pointing.
- **Request time** - time elapsed between sending a request to the link and receiving a response.
