Mehr aus 404
Wofür du ihn nutzen kannst
Auf der Website einer Praxis sammeln sich tote Links schnell an: das Profil einer Ärztin, die nicht mehr da ist, ein altes Terminformular, der Hinweis zur Grippeimpfung vom letzten Winter. Wer dort landet, ist oft schon etwas beunruhigt. Eine ruhige, eigene 404-Seite hält die Leute und bringt sie mit einem Klick zurück zur Anmeldung.
Der Witz mit dem fehlenden Puls passt zu einer Zahnarztpraxis, einer Physiotherapie oder einer Privatklinik mit lockerem Ton. Bei Onkologie oder im Krankenhaus schreibst du den Titel lieber nüchterner. Am meisten bringt oft die Telefonnummer für Termine in der Nachricht.
