Google: le début de la fin?
Les revenus apportent la paranoia
Des reactions brutales

Les revenus apportent la paranoïa


Et puis Google a commencé à grandir, à grossir. Notamment en mettant en place dans un premier temps des liens publicitaires sponsorisés dans ses résultats de recherche, puis en mettant des liens similaires sur des pages de sites tiers: les publicités AdSense promettaient quelques revenus aux webmestres, sans trop de problème de commercialisation.
C'est sans doute là, je pense, que la mécanique s'est emballée et a pris un chemin dangereux:
Déjà, pour occuper de bonnes places dans les résultats des recherches, toute une industrie s'est développée autour du référencement. Et ce qui faisait la force de Google, un algorithme mathématique pour définir la pertinence et la qualité du contenu d'une page, est devenu la cible  de toutes les sociétés de référencement, qui ont cherché à utiliser au mieux cet algorithme et ses caractéristiques. Google avait beau protéger le secret de ses algorithmes, il y avait toujours des petits malins pour tricher...
Les enjeux de cette "créativité", c'était de paraître dans le haut des classements, car cela pouvait signifier la vie ou la mort de certaines entreprises, notamment les "dot.com" n'exerçant leur activité que sur et par le web.
Premier souci donc pour Google: que des petits malins manipulent le contenu des pages pour être injustement bien référencés. En effet, cette injustice pénalise d'une part ceux qui jouent honnêtement le jeu et fournissent un bon contenu en espérant être bien référencés, d'autre part les annonceurs qui achètent en argent sonnant et trébuchant (belle expression, de plus en plus virtuelle!) le fait d'être bien placés à côté des résultats des recherches.

Mais le problème s'est encore amplifié avec les publicités AdSense: pour ces publicités, Google analyse à la volée le contenu des pages pour déterminer quelles publicités y serait adaptées, prenant en compte le contenu de la page et le contenu général du site. Là encore, les manipulations ont été nombreuses, et Google a suivi de près les manipulations, modifiant régulièrement ses divers algorithmes pour éliminer et corriger ce qui paraissait douteux.
Un problème similaire s'est produit autour des publicités: la plupart sont facturées à l'annonceur "au clic", c'est-à-dire quand un visiteur du site clique sur une publicité AdSense; et ce clic est, en parallèle, payé au site sur lequel la publicité était affichée. Là encore, de petits malins ont entrevu une possibilité d'augmenter rapidement leurs revenus, en effectuant (ou en faisant effectuer) des "clics frauduleux". Et là aussi, Google a suivi de près chacun des clics, recueillant des statistiques pour déterminer si les clics étaient légitimes ou non. Ce qui n'a d'ailleurs pas empêché la fraude au clic de prendre des proportions importantes: voir notamment
