Thank's

 

There are many scripts to check Google pagerank here is one:

And this script I just made to check Alexa Rank, MSN/Yahoo and Google Backlinks:

Peace,

 

Is there a way to load the pagerank, # of backlinks and alexa rank into a database for sorting?

 

The main question is how to get those values.

Inserting them into Mysql shouldn't be hard if you have simple PHP/MySQL knowledge.

Peace,

 

It just doesnt seem obvious to me....
