Du hast sicher Recht damit, daß die Platzhalter meist nicht so früh am Anfang des Content-Inhaltes stehen werden.
Ich würde allerdings trotzdem von einer hohen Dunkelziffer ausgehen weil die Meisten selten bis nie in den Seitenquelltext schauen und auch SERPs nicht so oft prüfen.
Die folgende Methode um das Problem zu beheben ist erst ab Shop-Version 2.0.5.0 möglich, da vorher kein Hook für die Meta-tags in der
/includes/modules/metatags.php vorhanden war.
Das Auslagern der Funktion in
/inc/ und das Ersetzen des Codes im Smarty-Modifier ist immer möglich.
In Shop-Versionen vor 2.0.5.0 muß man die Meta-tags dann wahrscheinlich im genannten File selbst mittels der Inc-Funktion "säubern". Habe mir das nicht genauer angeschaut.
Man generiere eine Datei namens
contentenhancer.inc.php in
/inc/ mit diesem Inhalt:
