Abstract

Die Ausgangslage für Suchfunktionen auf Unternehmens-Websites stellt sich grundlegend anders dar als bei Internet-Suchdiensten. Nicht die möglichst breite Erschließung von Informationen vieler verschiedener Websites, sondern der erfolgreiche Dialog mit den Nutzern steht im Vordergrund. Das Gelingen dieser Kommunikation wird in diesem Beitrag untersucht. Von 56 Schweizer Unternehmen und Behörden wurde jeweils die Suchfunktion der Website untersucht. Dabei gruppierten sich die insgesamt 74 Einzeltests in die vier Hauptkriterien: Suchindex, Vergleich von Anfragen und Dokumenten, Benutzerinteraktion und Suchergebnisse. Die Resultate zeigen großes Potential für Verbesserungen. Dabei wurden kein Ranking der Websites und keine Auszeichnung im Rahmen der Studie beabsichtigt. Vielmehr wurde auf Basis der Ergebnisse eine Einteilung in gute, mittlere und schlechte Websites für die einzelnen Kriterien durchgeführt. Die Analyse zeigt, dass keine Website in sämtlichen getesteten Kriterien sehr gut abschneidet. Die Studie schließt mit verschiedenen Empfehlungen, die dazu führen können, die Qualität der Suchfunktion wesentlich zu verbessern. Hierbei wird unter anderem empfohlen, der Aktualität und Vollständigkeit des Suchindex besondere Beachtung zu schenken, Metadaten der Dokumentenbasis zu pflegen, bewährte Standards für die Benutzerinteraktion zu beachten und Trefferlisten sowie potenzielle Suchanfragen auch auf eine mögliche Nutzersicht hin zu optimieren.
