Abstract
"Alle benutzen Google". So läßt sich kurz und prägnant die Entwicklung im Bereich der WWW-Suche in der letzten Zeit auf den Punkt bringen. Durch gute Suchergebnisse und eine schlichte, ausgesprochen gut bedienbare Benutzerschnittstelle hat sich Google als die Suchmaschine für alle Zwecke etabliert. Im Zuge dieser Entwicklung fanden größere Veränderungen auf dem Markt statt: Einige Bewerber mussten ihre Suchwerkzeuge aufgeben, neue Firmen haben dafür die Herausforderung angenommen, dem Benutzer noch bessere Ergebnisse oder wenigsten innovative Features zu bieten
