How to display the page rank
If you are looking for a way to determine the Google page rank for a group of websites, here’s a simple solution:
Download the page rank script and test it on your web server.
Note that the server is forced to query one of Google’s servers each time you call the page rank function. Because page rank doesn’t change very often (at least the one displayed by G’s toolbar) you can greatly improve performance by caching it. For example if you run a directory of websites you can set up a cron job to run and keep the page rank values updated.
Imagine the time it would take for a page with more than 400 URLs to display the page rank in real time (e.g. DirPedia).
