It seems that some sites have already noticed shifting PageRank values, as early as January 10th.
The last update happened in late October of last year. So maybe we'll be seeing updates continue until the end of the month.
With the changes put into effect to account for paid links, I don't think the update will hold entirely to historical trends. Paid links seem to be pretty widespread, and if every page with at least 1 paid link goes from PR whatever to PR 0, the collective PR of the entire net is likely to be affected.
Of course, going from a PR 0 to a PR 5 is like creating something from nothing. They say the more pages of content your site has, the more PR you've got. So as more pages are added to the net, the net's total PR will increase. But when Google arbitrarily changes the PR prerequisites (no paid links), it's bound to have an effect.
I see two possible outcomes. As some would say, "Paid links are here to stay," and so Google will eventually allow PR on paid link pages. On the other hand, Google is king, so perhaps the paid link, paid post, paid whatever industry will sink its claws into the ground and slowly get dragged toward an inevitable death that few want to believe is already underway.If you enjoyed this post, I'd be delighted to have you as a subscriber to my RSS feed.
