Getting PR and Alexa.

Hi,
I am looking for direction for creating a script, or finding one for getting at least Google PR and Alexa ranking. I am building a database which will contain a few thousand links, and I would like to be able to set a cron and have the PR and Alexa updated on a regular basis.

Thanks,
Michael

 

Well, I found a script a few posts down at '
http://forums.digitalpoint.com/showthread.php?t=2260553


To get the Google PR, but I keep getting a pr of -1 returned to me. Now I am running this on my local machine right now, does this need to be uploaded to my server to actually work?

Thanks,
Michael

 

Yes It requires to upload in server.

 

Includes Alexa rank, all you need to do is set up your mysql statement to grab urls from your database.

Thanks very much for that. I should be able to get the rest figured out. I just wasn't sure how to get the info I needed.

you can find many free script on google

 

I am getting a lot of pr returned as -1. I have tested a few of the sites manually, and they work, and return a pr. Does google limit the number of searches or doing something that might be blocking me if I do to many at a time? or is there something else that might be going on.

Thanks,
Michael
