As a Manchester SEO company, a lot of our clients ask us about Page Rank so we decided to write a brief definition for Page Rank in real terms and how it affects your SEO.


What is Page Rank?

Page Rank is a measure or mark out of 10 that Google assigns a website, it was named after Larry Page (co founder of Google) and uses link algorithms to define the numerical value. The algorithm takes into account the relevance and value of the links as well as age of the site and trust of the domain and link to the site.

Sites are always improving so Google often changes the benchmark, sites such as the BBC and Amazon are well established and continue to improve with good content and links therefore as these sites move closer to the holy grail of 10/10 Google will move the posts so these sites continue to be at around 9 or 10. To keep this fair this change is applied across all websites, this means if a site has not improved there is a chance they can lose a Page Rank. This is because there is a possibility that the website could go down, but all the sites linking to that site can go down in PR as well, which has a knock-on effect on your site.

Naturally sites should improve and gain links as people reward good content, however, SEO’s can help you along with your PR by helping you improve your site on page as well as off page with natural link building and link bait.

Page Rank is a good indication of how well your site is performing but a high page rank will not guarantee good results in the SERPs (Search Engine Results Pages), however determining your competitor’s Page Rank can give you a good benchmark to work towards.

To see your site’s Page Rank there are many tools that will show you such as Google toolbar for Firefox.
