It really depends on what you mean by PPC on your website. If you mean PPC to direct traffic to your website, then you need to set up an Adwords campaign on Google, and/or the equivalent in Miva, Yahoo etc.
If you mean you want PPC advertising on your own site, then you need to see Google Adsense (or the equivalent elsewhere).
If you are in the UK, you might want to catch my workshop tour, where I cover all aspects of PPC, Adwords, Adsense, and much much more. More details are available on www.ebusinesstutor.co.uk.
