Abstract
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? Das Buch betrachtet Suchmaschinen aus vier Perspektiven: Technik, Nutzung, Recherche und gesellschaftliche Bedeutung. Es bietet eine klar strukturierte und verständliche Einführung in die Thematik. Zahlreiche Abbildungen erlauben eine schnelle Erfassung des Stoffs. 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 Suchmaschinenmarktes, der Bedeutung der Suchmaschinenoptimierung und der Rolle der Suchmaschinen als technische Informationsvermittler. Das Buch richtet sich an alle, die mit Suchmaschinen zu tun haben und ein umfassendes Verständnis dieser Suchwerkzeuge erlangen wollen, u.a. Suchmaschinenoptimierer, Entwickler, Informationswissenschaftler, Bibliothekare, Rechercheure in Wissenschaft und Praxis sowie Online-Marketing-Verantwortliche. Für die zweite Auflage wurde der Text vollständig überarbeitet. Neben einem neuen Kapitel zur Suchmaschinenwerbung wurden zahlreiche Abschnitte zu neu aufgekommenen Themen hinzugefügt. Alle Statistiken und Quellen wurden auf den neuesten Stand gebracht.
