PageRank: que du marketing?

Selon certains chercheurs, il semble que PageRank ne soit pas particulièrement un bon algorithme malgré sa grande popularité et son prestige certain. Voyez plutôt ce qu’en disent Upstill et al.:

Log of indegree was highly correlated with Google-reported PageRank scores, and just as effective when predicting desirable company attributes. Further, we found that PageRank scores for sites within a known spam network were no lower than would be expected on the basis of their indegree. We encounter no compelling evidence to support the use of PageRank over indegree.
