Much like you shouldn't judge a book by its cover, you can't determine the link value of a website by its Google Page Rank status, either. Take a look at several factors: check the Alexa rating of the site, the number of pages indexed at Google, MSN, and Yahoo!, as well as the back-link popularity. Use free online resources such as Yahoo! Site Explorer at SiteExplorer.Search.Yahoo.com and browse sites like Suma-Tools, SEO Book. Get back [links] to the basics!
