What is PageRank?
PageRank is the algorithmic value Google assigns to web pages based on the volume and caliber of links to the pages. Although Google once published a public toolbar score of 1-10, that external metric only approximates the complex, private calculations that drive search results. Fun fact: PageRank was named after one of Google’s founders, Larry Page, and operates on a per-page basis, hence the pun.
Examples of PageRank would include observing a toolbar PageRank increase after receiving a quality backlink, comparing internal links and adjusting them to grant authority to primary service pages, and comparing PageRank equivalents on competing domains.
