PR changes ever expected this month and was reported as early as January 2, 2007 for some sites. I only noticed changes on some of my sites on January 8, 2007 but on some other sites, there are still no changes as I still believe changes are still propagating. Although the changes I have been seeing are not really favorable. Here are a few observed changes from me and some of my friends.

• SEO Contest Entry, missing in SERPs and zero PR homepage: Was number 1 on Google. This SEO contest is over already and my site was number 1. During the end of December to 1st week of January. Today it is not in the first 10 pages of Google, but is still in the SERPs checking with a site command. PR was zero, and the homepage still has PR0. But inside pages of the site have PR4. Something I do not understand if PR is still propagating or I am getting penalized for some reason I am not aware of.
• Personal blog with PR4 back to PR0: A friend of mine with his personal blog had a PR4 homepage. He has a multi-topic blog well categorized into topics in subdomains using the subdomain plugin. Some of his category pages have increased PR and retained PR, but homepage had PR4 to PR0. Mysterious.
• Game site back in the SERPs for brand name: A friend of mine was lost in the SERPs for his own brand name of his flash game site. He suddenly disappeared in December in the SERPs for his own brand name. But his RSS feed was number 1, but his homepage disappeared. He was thinking he got penalized but just this week, he was back to number 1.
• Celebrity site gone from 1st page: My celebrity site was on the first page for her name on Google. Today it is gone from the first 5 pages. I did not even bother to check beyond that. A site command shows it is still in the SERPs, but disappeared. I am not sure what the reason is. But majority of the traffic of the site is from strategic linking with partner sites, so I am not really that 100% worried about it missing in the SERPs.
• Entertainment industry blog on blogger missing in SERPs: This is even worse, even the site command is showing no results for his blog and his blog is even on Google’s Blogger.

But since I have experienced missing pages before, that are like dead and rose back from the dead and even become stronger in the SERPs, I am not that worried unless my high ranking pages are lost for more than a month. There are several people chatting with me via IM’s worried. Funny thing is the Entertainment industry blog I mentioned, the owner of the site even did a reinclusion request. *LOL* And I think he is not even banned.

As I was not in panic mode and just waited what will happen, Mike Lopez did his research already, and pointed out Matt’s post not to panic. So if you have missing SERP pages, or PR0′s, just wait a bit and see what happens.
