All indications are that the Google PageRank rollout is going on right now. Evidence is that a few sites formerly without a PR ranking now have one. But wait until Monday before you start worrying, as some PR indicators will fluctuate.
Now this isn’t something most of us will ever experience for our sites, but Jack Humphrey posted an article last weekend about a list of PR10 sites at Search Engine Genie. It’s a very short list, but proof that they do exist – in case you doubted anyone site other than Google.com has a PR10.
However, this list, as far as I can tell, is from Jan 25, 2007, and some of the sites listed – including apple.com – are showing as PR9, according to my SearchStatus for Firefox extension. Apparently Google lost a lot of PR10 pages as well, so we’re not the only people who suffer the decline. Except Google never has to worry about how much money their pages will earn from running someone else’s ads.
If you’re interested in a bit of PR10 history, check out the links at the bottom of the list, which show PR10 sites as far back as early 2004.
Generally speaking, don’t get too obsessed about the PR of your sites except for ad networks that use it to measure what you’ll get paid for ads. I’m a firm believer in organic growth of backlinks, but I use the term “organic” very broadly.
