Technique of reference aiming at influencing the classification of a page in the results of the research motor Google. This technique exploits a characteristic of the motor PageRank ™ which grants a certain weight in the text including a link hypertext towards a page. This weight can vary according to the algorithm used employed by Google. If several sites use the same text to clock in on the same target, Google figures up this weight and it becomes possible to show the target page in the results of a research on the text contained in links clocking in towards her.
