    Kennen Sie "Nigritude Ultramarine"? Nein? Fragen Sie doch Anil Dash. Oder vielleicht Google - aber dann könnten-Sie ebenfalls bei Dash landen. Der Internetautor ist Sieger eines ungewöhnlichen Wettbewerbs der Online-Werbefirma Darkblue: Einen Monat lang sollten Webseitenmacher Google veräppeln - und dafür sorgen, dass ihre Seite oben steht, wenn Surfer nach dem Phantasiebegriff suchen. Fast eine halbe Million Seiten stehen nun in der Ergebnisliste. Das stärkt Kritiker, die schon lange warnen, Google sei manipulierbar. Zugleich sammelt mit Yahoo und Microsoft die Konkurrenz ihre Kräfte. Die Lage für den Marktführer wird schwieriger - und das just in der Zeit, in der Google an die Börse strebt. Fachleute spekulieren, das Unternehmen wolle noch in diesem Monat seine Aktien über eine Internet-Auktion verkaufen. Die Stärke wird zur Schwäche Googles "Nigritude Ultramarine"-Schwäche ist die Folge einer eigentlichen Stärke: Die Suchmaschine merkt sich die Inhalte von Webseiten - und sie bewertet darüber hinaus deren Wichtigkeit. Als Maßstab prüft sie, wie viele andere Seiten auf die gefundene Adresse verweisen. Die Logik dahinter: Nennen viele Webautoren eine bestimmte Seite, muss sie interessanter sein als andere mit ähnlichem Inhalt. Google schaut zudem nach, mit welchen Begriffen Surfer auf weitere Angebote verwiesen werden - diese Link-Texte sind besonders wichtig für die Bewertung der Zielseiten. Politische Aktivisten nutzen das manchmal aus. Sie sorgen etwa dafür, dass bei einer Suche nach "miserable failure" ("klägliches Versagen") die Biografie von US-Präsident George W. Bush die Ergebnisliste anführt. Auch konservative Internetkenner arbeiten mit dem Trick: Eine Recherche nach "Waffles" (Geschwafel) führt zum Herausforderer John Kerry. Wesentlich ärgerlicher als solche Politik-spielereien sind' die Machenschaften vieler so genannter Search Engines Optimizers, kurz SEO. Der boomende Wirtschaftszweig lebt davon, die Webangebote der Kunden auf Trefferlisten möglichst weit nach oben zu bugsieren. Webmaster aus der Pornobranche nehmen die Grauzonen-Dienstleistungen gerne in Anspruch. Auch professionelle Ebay-Händler und Partner des Webkaufhauses Amazon arbeiten mit Tricks, um ihre Adressen mit allen nur erdenklichen Suchanfragen zu verknüpfen. Die neueste Masche: Die SEO-Branche lässt eine Software auf das Internet los, die automatisiert und massenweise Kommentare schreibt. Die austauschbaren Stellungnahmen der Güteklasse "coole Website" oder "interessanter Text" enthalten einen Verweis zu der Seite, für die geworben werden soll. Das Kalkül dabei: Google findet die Einträge und erhöht die Bewertung der verlinkten Seite. "In einer Nacht sammelten sich Hunderte der Kommentar-Spams in meinem Weblog an", stöhnt der Düsseldorfer Blogger Siggi Becker, "allesamt führten sie zu Porno-Websites des untersten Niveaus." Ihn ärgert der Arbeitsaufwand, um die Roboter-Hinterlassenschaften zu löschen. Und er fügt hinzu: "Man fühlt sich ein wenig beschmutzt."
