Recently the SEO world has just experienced a minor shake up concerning Google’s latest Page Rank update. Several sites’ PR dropped and some increased. But most of the highly visible SEO websites have experienced shocking changes in their PR statuses.

It was my friend, Junelle, from Intiendes.com who first mentioned this latest Google update to me through chat. I wasn’t aware of it because the PR of my blog, Malditang Pinay, neither went down nor up. It stayed at PR 4. Lucky me!

Junelle is very happy because her newest blog AOV Philippines Outsourcing Services has climbed from PR 0 to PR 3 after the update. That’s an early Christmas gift from Google to her. Hehehe! Congrats Junelle!

Update on this post (Oct 31, 2007):

I just found a good explanation on why some sites lost a few points on their Page Rank. Here is a brief quote from Andy and Aaron’s Link Building article at SEOBook.com:

What will happen to the way search algorithms score links is already happening. The Google algo has become much more elegant and advanced, devaluing staggering amount of links that shouldn’t count, and placing more emphasis on trusted links. And the trust and juice given by those links is then verified by elements like user data, domain age, and other relatively hard-to-spoof factors.

It must be that Google has changed the criteria for Trusted Sites. I mean lots of websites will surely link to SEO sites, but few of those can be evaluated as TRUSTED, so this is the reason why many SEO sites also lost some PR points. I don’t know if this is true. I am just theorizing here. What do you think happened?
