Abstract
Das Buch betrachtet das Thema Suchmaschinen ausgehend von der täglichen Recherche und führt in die technischen Grundlagen, in Recherchetechniken sowie die gesellschaftlichen und wirtschaftlichen Bedingungen der Recherche im Web ein. Suchmaschinen sind heute die wichtigsten Werkzeuge, um an Informationen zu gelangen. Wir verwenden Suchmaschinen täglich, meist ohne weiter darüber nachzudenken. Doch wie funktionieren diese Suchwerkzeuge eigentlich genau? Neben einer ausführlichen Darstellung der in den bekannten Suchmaschinen verwendeten Rankingverfahren wird auch ausführlich auf das Nutzerverhalten eingegangen, das wiederum die Ergebnisdarstellung prägt. Dazu kommen grundlegende Betrachtungen des Suchmaschinenmarkts, der Bedeutung der Suchmaschinenoptimierung und der Rolle der Suchmaschinen als technische Informationsvermittler. Nicht zuletzt wird auch die Seite der Recherche betrachtet und gezeigt, wie man mit den bekannten Suchmaschinen effizient recherchieren kann. Das Buch verhilft allen, die mit Suchmaschinen recherchieren oder sich beruflich mit der Optimierung, Aufbereitung und Sichtbarmachung von Inhalten beschäftigen, zu einem umfassenden Verständnis der Ansätze, Stärken und Schwächen verschiedener Suchmaschinen und der ihnen zugrunde liegenden Technologien.
