Well now days I found that Page Strength is going more popular and some people are saying that it will take place of Google's Page Rank. You can check your Page Strength here:

I have never heard of page strength before. How do you achieve it and what does it do for you? Does it help you get a better page rank or is it something different all together?

Well when you visit the site you can see that they mention about importance. Read:

• The Relative Importance and Visibility of a Webpage
  
• The Potential Strength and Ability of a Page to Rank in the Search Engines
  
• Data on Popularity, Links & Mentions of the Page Across the Web
  

So I think that rank would be important for any buyer if he want to links from good pages.
