How to add a sitemap.xml in Astro
A sitemap is how you tell a search engine which pages exist and when they last changed, rather than waiting for every one of them to be found by following links. Without it, pages that are not linked prominently can go months before they are crawled at all.
The fix for Astro
13x detects your framework from the response and hands you this version rather than the generic one — below 50% confidence it hedges and gives you the generic one instead.
Add the official sitemap integration:
npx astro add sitemap// astro.config.mjs
import sitemap from "@astrojs/sitemap";
export default defineConfig({
site: "https://example.com", // required, the integration is a no-op without it
integrations: [sitemap()],
});The output is /sitemap-index.xml. Point robots.txt at that, not sitemap.xml.
On a different stack? The general version of this fix explains what 13x checks and why it matters, without assuming a framework.
