Why Does Anyone Care about Page Rank?
Google uses a numbering system — page rank — to determine how relevant each is blog is. The system is based on a complex algorithm that places weight on how blogs are linked. I explained it this way during the Google Page Rank Update last February.
Page rank determines how relevant your blog is by using linking as a vote system. Google has developed an algorithm that weighs links between blogs A to B to C to A, and also looking also at the importance of the blogs making the links. Quality blogs that are well connected to other quality blogs are considered highly relevant to Google users. Relevant, quality, important blogs receive higher page ranks. Higher page ranks can mean higher advertising payments for blogs that monetize.
Many tools are available to help you query Google’s various data centers to check for any changes in PageRank values for a given URL. During most times the data centers deliver the same rank, however during an update you might get a glimpse of changes URL’s PageRank value. Beaware that the information is only as accurate as the tool you use. I’ve had rankings predictions vary as much as three points between tools.
Google changes their algorithm frequently. This is the tool that I use. Click the image to go there.
Keep in mind that many fluctuations occur and that the dance takes many days before things settle down into their final place.
