Many webmasters speculated that Google might have discontinued the PageRank information.
For Google to hold its own against upstart search engines, it must deliver on its PageRank promise.
Most website owners do not utilize properly what PageRank they already have.
Google uses PageRank (PR) to determine a page's importance on the World Wide Web.
A link is worth more for your PageRank if it comes from a site that is relevant to your site.
A link from a floral website would not be relevant to a computer website, so it would not do much to improve PageRank.
The number of links on a site also plays a role in how valuable the link is for your PageRank.
For example, a rather dubious adult website managed to get a pagerank of 10.
Then you would be getting 80 times more PageRank boost from the Ugly Duckling website than you would from the 500 pound gorilla website.
Many webmasters are still obsessed with the green PageRank bar in Google's toolbar.
Link Popularity and Google PageRank are almost secondary for the overall success of a website.
