xml-Sitemap für Google erstellen

Beitrag von Freddy » Sa 9. Nov 2019, 19:03

Hallo Zusammen,
möchte eine Sitemap von der Webseite erstellen die bei Google Search Console einbinden kann. Dafür wollte ich das content_sitemap_xml-Modul welches man bei Installieren von Contenido mit installieren kann einsetzen. Leider bekomme ich dort die Ausgabe <loc>https://www.meinewebseite.de/index.html ... ang=1</loc> wo mich das ?changelang=1 stört. Glücklicherweise habe ich eine geänderte Version gefunden wo es richtig angezeigt wird. Jetzt würde ich gerne noch bestimmte Seiten ausschließen wollen damit diese nicht in der Sitemap auftauchen.
Da ich doch bestimmt nicht der Erste bin der dieses Problem hat wird es doch bestimmt schon ein Sitemap-Modul geben wo diese Funktion integriert ist.
Hier ist der Code vom modifizierten Sitemap-Modul wo die erweiterung der Sprachen nicht angezeigt wird.

Das Originalmodul respektiert, wenn du im Artikel unter SEO bei Robots ein Häkchen bei noindex setzt.
