Google PageRank Prediction – Future Page Rank Tool
This is fun to play with- but testing over the last year with 10 different sites- my experience has not been the greatest accuracy. Tho others have had different experiences. This is fine tool if a unsatisfactory result compels you to work harder on your site , write that content you have been meaning to get around to or find that extra back link.
I had one site at PR3 predicted to go to a pr2 (gulp) and at next Google update went to Pr4.
So as with most SEO tools and utilities that seem to be everywhere these days- this one for me goes to the fun to play with list.
The damaging part of some of these tools- I am not pointing at this one in particular- is they can’t fall into the wrong hands. A site owner can get a hold of them and start to play with them and misinterpret results or get a number he doesn’t quite understand Then end up calling or e-mailing about new “crisis” they found . Not fun. Keep in mind most of these tools can be found on professional SEO sites- so maybe a site owner will take action- perhaps hire their services?
Made a discovery this week . I have been having alot of trouble with one of my clients sites- despite a steady link campaign and great content it has not been perfroming as well as it should. I went to my SEO check list over and over. No duplicate content, unique meta data for all the pages, etc. Despite everything pages are being dropped from googles index and rankings have dropped. Ruud came up with what we think is problem: The site was moved from its server about 3 months ago. Most likely Google is going to the cached IP and getting all kinds of page errors.
I spoke with several other SEO’s and SEO experts and soon discovered that this is a fairly rare occurance; howver it is very real and does happen.
(with information from a Google engineer. Note this: […] until its able to resolve the address for your specific site. This can take up to 3 months to happen. In the meantime it will use the IP of the main site on this IP, often times the hosts site.)

This includes, for example, Google’s web spider. I moved my web site a while back, and more than a week past the DNS change and TTL expiration, the old server was *still* getting a slow stream of hits from Googlebot trying to spider the site.)
http://www.w3reports.com/index.php?itemid=549 (see Anthony’s comment: Search engines like Google will often store the IP address of the domain name (possibly a SiteID) when it discovers it. So taking an example from above, Google may first discover this URL:
And Google stores and associates the IP “123.456.789.012” to this domain. Why might they do this? To save on DNS queries which is the bottle neck of running a Web crawler of this size. What Google may do for future requests is first make a request for the IP (which is much more efficient than doing a domain name lookup) and once connected, make a request for the host name (domain name) and path.)
