Abstract

Google & Co. sind die zentralen Marktplätze im Internet; ohne sie würden sich nur wenige Menschen im Web zurechtfinden. Über 90 Prozent aller Internet-Nutzer greifen deshalb auf Suchmaschinen zurück - nicht immer als kundige Verbraucher, denn sowohl das WWW als auch die Suchmaschinen haben ihre Untiefen. Es beginnt beim Netz der Hyperlinks: Die Zahl der weltweit vorhandenen Webseiten ist technisch nicht zu bestimmen. Die Universität Bielefeld schätzt die Größe des frei zugänglichen WWW Anfang 2005 auf 10-15 Milliarden Seiten; Informationen in Datenbanken, auf geschlossenen und dynamischen Webseiten sowie die mit Webseiten verknüpften Dokumente hier nicht mit eingerechnet. Bei dieser Zahl wird klar, wie wichtig Suchmaschinen sind, um Informationen zu finden. Doch erfassen diese bei weitem nicht alles: Zwar verzeichnete Google im Januar 2005 laut eigener Aussage rund 8 Milliarden Webseiten, doch dürfte ein erheblicher Teil des WWW fehlen. Für Deutschland errechnete Andreas Pothe in einer Untersuchung für das Regionale Rechenzentrum für Niedersachsen, dass von den geschätzten 320 Millionen deutschen Webseiten nur 60 Prozent beim Marktführer Google zu finden seien. Schlusslicht Fireball kennt gerade einmal jede zweite deutsche Domain - und entsprechend weniger Webseiten.
