Majoritatea oamenilor cred ca Google foloseste doar formule matematice pentru a judeca pozitia website-urilor in motoarele de cautare. In momentul de fata Google are chiar o declaratie oficiala despre modul cum rezultatele afisate sunt calculate:
„A site’s ranking in Google’s search results relies heavily on computer algorithms using thousands of factors to calculate a page’s relevance to a given query. Sometimes subtleties of language cause anomalies to appear that cannot be predicted.”
