# What is Sitemap?

> A sitemap is a file listing the pages on your website so search engines can find them all, usually an XML file at an address like yoursite.co.uk/sitemap.xml.

Also called: XML sitemap, sitemap.xml.

An XML sitemap is a behind-the-scenes list of your website's pages, written in a format search engines read. It is not meant for humans, though you can open it in a browser and see a list of addresses.

It helps Google discover pages, especially new ones, and notice when pages have changed. You submit it once in Google Search Console, and most modern website systems keep it up to date automatically.

A sitemap does not guarantee pages get indexed or rank. It is a helpful map, not a set of instructions Google must follow.

## Why it matters for a small business

It is a small, free thing that helps Google find every page you have paid to have written. Its absence rarely sinks a small site, but a sitemap full of broken or out-of-date pages is a sign nobody is looking after the website.

**Example:** After a café adds a new ‘Private hire’ page, the updated sitemap tells Google it exists, so it gets crawled sooner instead of waiting for Google to stumble across it.
