Page Ranking- what it means
Page ranking also known as ‘PageRank‘ (PR) as trademarked by Google, is a numerical ranking system to determine importance on the web. The algorithm takes into account link analysis and ranks pages from a scale of 0 to 10. Larry Page originally designed the algorithm while at Stanford University. Stanford University holds the patent but Google purchased the exclusive license rights from Stanford.
All webpages are eventually page ranked. The higher the scale the more ‘important’ the website as opinioned by Google. For example, www.wikipedia.org and www.facebook.com rank a 9 while www.cbc.ca ranks an 8. Newly launched sites begin at 0 until they mature. Page ranking can be an important value to watch the success of SEO efforts. It can take months for a new website to change from a PR1 to a PR2. A step-up in the higher PRs is a much larger step and can take much longer.
Page ranking of websites is important for link building. A key SEO strategy is building inbound links. There is more benefit getting a link from a website with a high page rank such as a PR 4 or PR5 as compared to obtaining several links from sites with a PR1 or PR2.
