Abstract

Google ist die bei weitem beliebteste Suchmaschine; "Googeln" ist zum Synonym für internetrecherchen schlechthin geworden. Aber der Erfolg ruft auch zwielichtige "Suchmaschinenoptimierer" auf den Plan, die mit allerlei Tricks die Trefferlisten manipulieren.

Content

Die Suche mit Google, früher meist auf Anhieb erfolgreich, bereitet in letzter Zeit zunehmend Frust. Sucht man zum Beispiel mit den Begriffen "kfz kaufen lüneburg" nach Autohändlern in der Heidestadt, erhält man als ersten Treffer eine Site, die laut Inhaltsangabe in der Trefferliste die Begriffe "Eu-Auto Neuwagenmarkt kaufen Reimport-Auto Fahrzeug" enthält. Als Adresse gibt die Suchmaschine eu-reimport-auto.department1.de/kaufen/ an. Doch dieser Treffer passt nur scheinbar gut zu der Anfrage. Klickt man nämlich auf den Link, landet man nach mehreren Weiterleitungen auf verschiedenen anderen Sites, meistens auf einer allgemeinen Startseite von eBay, http://pages.ebay. de, auf der man dann vergeblich nach "lüneburg" und "kfz" Ausschau hält. Sucht man mit der Abfrage "diascanner test" nach Diascanner-Vergleichen, dann führt der erste Treffer zur Ergebnisseite einer anderen Suchmaschine namens Biveroo mit nutzlosen Verweisen, obwohl der Link angeblich auf die Site www.sisira.de führen soll. Die zweite Site in der Trefferliste listet unter der Domain diascanner.org eBay-Auktionen und Links des Pay-forPerformance-Anbieters Espotting - also gekaufte Links, Werbung. Testberichte? Auch hier Fehlanzeige. Insgesamt finden sich unter den ersten zehn Verweisen nur drei relevante. Surfer erhalten bei Google-Recherchen im Umfeld von Produkten und Dienstleistungen immer mehr unbrauchbare oder in anderer Weise ungewöhnliche Treffer: Webseiten, die mit der Abfrage kaum etwas zu tun haben, zum Teil nicht einmal den Suchbegriff enthalten, wirre Linksammlungen oder gar Ergebnisseiten anderer Suchmaschinen. Mitunter landet man nach dem Klick auch bei einer anderen Adresse, als Googie in seiner Ergebnisliste angibt. Immer seltener finden sich neutrale Informationen; statt dessen landet der Surfer immer häufiger in irgendwelchen Online-Shops oder auf E-Commerce-Portalen. Verseuchte Ergebnisse Die Verseuchung der GoogleSuchergebnisse durch aufdringliche Geschäftemacherei ist findigen Tricksern zu verdanken. Sie haben Wege gefunden, bei immer mehr Suchanfragen ihre Links unter den ersten Treffern zu platzieren. So fällt nun auch Google einer Entwicklung anheim, die viele andere Suchdienste bereits vor Jahren heimgesucht und weitgehend unbrauchbar gemacht hat. Dabei galt doch der geniale Google-Algorithmus zur Bestimmung der Trefferrelevanz ("Ranking") lange Zeit als immun gegen Manipulationsversuche. Der Suchmaschinenprimus zieht nicht nur die in den HTMLSeiten enthaltenen Schlüsselwörter heran, wie es die Suchdienste in der Vor-Google-Ära taten. Stattdessen bestimmen bei Google vor allem Verweise fremder Seiten und damit die Wertschätzung durch andere Webmaster darüber, welche Position eine Website in der Trefferliste erhält. Aber nicht nur die bloße Anzahl der Links, sondern auch der Rang der verweisenden Website fließt in die Bewertung ein. Daraus errechnet Google den so genannten Page Rank, benannt übrigens nach dem Erfinder Larry Page [11. Jedermann kann sich mit der erweiterten Version der Google-Toolbar für den Internet Explorer den Page Rank beliebiger Seiten anzeigen lassen.
