decrease the google ranking of a site?

Hi, can you decrease a rank of a site?
if yes, how can I do it?

Just shoot Matt Cutts an email and use the secret code phrase "The eagle has landed" in your P.S.

He'll know what to do.

Of course you can. Using google bowling or some derivative of it will get the job done nicely. However, keep in mind if you're doing this to another black hat they'll likely try to get you back. Just hope they're not better than you! You may find yourself with a worthless empire of sandboxed domains. You'd be better off analyzing your competitors site to gain incite into what they're doing to achieve a higher ranking. Once figured out, find a way to automate the things they've done to one up you and take that spot over.

Google's Terms of Service do not allow the sending of automated queries of any sort to our system without express permission in advance from Google. Sending automated queries absorbs resources and includes using any software (such as WebPosition Goldâ„¢) to send automated queries to Google to determine how a website or webpage ranks in Google search results for various queries.
