# Sitemap

> Category: Discoverability

A sitemap is how you tell a crawler which URLs are canonical and when they changed, without making it discover your site by following links.

## Why it matters

Agents with a budget will spend it on the URLs you name. Saying nothing means they guess.

## Pass criteria

A valid XML sitemap is served at /sitemap.xml, or declared with a Sitemap: directive in robots.txt.

## How to implement it

Goal: Publish a sitemap and reference it from robots.txt

A valid XML sitemap is served at /sitemap.xml, or declared with a Sitemap: directive in robots.txt.
