What is Google PageRank?

PageRank is the Google measure of Search Engine link popularity and is only visible if you have the Google toolbar installed. The Google toolbar displays PageRank in a scale between 0 until 10. Google PageRank is only relevant to the page being viewed in the browser NOT THE ENTIRE SITE. Remember search engines rank web pages not websites and PageRank is only one part of Google's complex search engine algorithm.

PageRank Explained by Google

Although Google was the first major search engine to use link popularity as part of its ranking algorithm, most spidering search engines now use link popularity when ranking pages. PageRank evaluates page Relevance through link analysis. The Google PageRank algorithm calculates the quantity and quality of links pointing to each and every page in the Google index.

Pages with many, quality links pointing to them are regarded as highly relevant!

Google's software engineer Matt Cutts comments, "Google's PageRank search technology works by first identifying the link structure of the entire Web, then ranking individual pages based on the number and importance of pages linked to them."
