### Speicherort

* Speichere diese Datei als **`sitemap.xml`** im **Root-Verzeichnis** deiner Website (also dort, wo auch `index.html` liegt).
* Beispiel: `/var/www/html/sitemap.xml` oder direkt im Hauptverzeichnis deines Hosting-Servers.
* Danach kann Google die Sitemap unter `https://european-minerals.eu/sitemap.xml` aufrufen.

Optional kannst du die URL auch in der **Google Search Console** einreichen, damit Google alle Sprachversionen erkennt.
