Zola will look for a sitemap.xml file in the templates directory or use the built-in one.

If your site has more than 30 000 pages, it will automatically split the links into multiple sitemaps, as recommended by Google:

All formats limit a single sitemap to 50MB (uncompressed) and 50,000 URLs. If you have a larger file or more URLs, you will have to break your list into multiple sitemaps. You can optionally create a sitemap index file (a file that points to a list of sitemaps) and submit that single index file to Google.

In such a case, Zola will use a template called split_sitemap_index.xml to render the index sitemap.

The sitemap.xml template gets a single variable:

  • entries: all pages of the site, as a list of SitemapEntry

A SitemapEntry has the following fields:

permalink: String;
updated: String?;
extra: Hashmap<String, Any>?;

The split_sitemap_index.xml also gets a single variable:

  • sitemaps: a list of permalinks to the sitemaps
