How does a PayPerClick site work?

[zan15]

Can anyone guide me the working of a PPC site? I understand the concept of advertisers and publishers but fail to understand that how a PPC site decides which ad to be displayed on which publisher site if there are 10 sites from the same category...

Thanks in advance.

Basically the more you pay for the keyword the more likely you are to get the top site of that ten.
