i checked your website it's nice but not provide PPC information while you said here that your website providing PPC information..so if you have anyone website/doc file then share now....
You might want to take a look at the Google Adwords Help Center. They have a plethora of PPC information there for you. Here are links to them: http://adwords.google.com/support/aw/?hl=en http://www.google.com/adwords/learningcenter/ Good luck!
the wikipedia entry for PPC is pretty helpful, at least for some solid background... just search PPC at wikipedia
