XML Sitemap

A list of URLs for search engines that helps faster indexing.

What it is

An XML sitemap is a file (usually /sitemap.xml) with a list of all the site's important URLs. Search engines use it to discover content faster and more completely.

Why it matters

Without a sitemap, Google relies only on links: it may discover new or deeply nested pages slowly or not at all. A sitemap speeds up indexing, especially on larger and newer sites.

How to do it

1Generate sitemap.xml with all indexable URLs (a CMS usually does this itself).
2Include only canonical, indexable pages (not noindex, not redirects).
3Add a reference to the sitemap in robots.txt and submit it in Search Console.
4Keep it up to date automatically when a page is added or removed.

Reference in robots.txt

Conclusion

A sitemap is a cheap insurance for indexing. On a small static site it's not critical; on an e-shop or a site with thousands of pages it's a must. Above all, keep it current and free of non-indexable URLs.
