Google PageRank Formula: Changes Over Time

(Page 1 of 5 )

To more fully understand how Google calculates and assigns PageRank, it’s necessary to consider the changes made since the inception of the formula. Wayne Hurlbert sheds light on the Topic-Sensitive PageRank calculation method.

Google PageRank is a fundamental building block of the Google algorithm. While the relative weight and importance of PageRank is debated by search engine optimization (SEO) professionals, there is little doubt that Google considers the measure to be important. From the very beginning of Google’s rise to the dominant search engine, its search algorithm has placed varying levels of emphasis on PageRank.

Started as a fairly simple and elegant formula, PageRank determination has undergone a number of changes over time. Exactly what those changes entail has been a source of debate within the SEO community. The generally agreed upon PageRank calculation involves more factors than simply examining the sending page’s PageRank level and the number of links on the page. To more fully understand how Google calculates and assigns PageRank, it’s necessary to consider the changes made since the inception of the formula.

Search engine optimization experts believe that many more factors have been added to the Google PageRank calculation formula. While many of the potential additions to the formula are speculative, there is some evidence as to their being included in the consideration. They include sending and receiving page themes, and sending and receiving page topics. In fact, on and off page topic consideration has opened up an entirely new SEO field called Topic Sensitive PageRank (TSPR).

Search engine optimization experts who are searching for ways to increase their Google PageRank have many more factors to consider than previously thought. Because Google has obviously changed their PageRank formula, we need to examine the many possible factors used in that new calculation, including Topic Sensitive PageRank.

Understanding the many factors considered in calculating Google PageRank will enable you to raise the PageRank levels for all of your web pages.
