Google's PageRank algorithm is the system that originally powered the search engine's rankings (and remains an important factor today). The Google Toolbar shows a score from 1 to 10 (on a logarithmic scale, meaning it is an order of magnitude more difficult to achieve a 5 over a 4, etc.) that estimates the relative link popularity of a page. | Google's PageRank algorithm is the system that originally powered the search engine's rankings (and remains an important factor today).
