How can I recognize Organic link or PPC link

Support & Bugs
1

I am working on the functionality by using piwik to differential organic link(The main links) from PPC link(The paid links) at google.

I know the visit.php contains the codes to retrieve info form google search result. for example, I can get the referer_url as
http://www.google.com/search?q=piwik&i…lient=firefox-a

however, the referer_url has nothing to do with my issue, so does anyone know whether piwik is able to recognize each of them?

As i know, when you right click those links, organic link would show:
http://www.google.com/url?sa=t&source=…T-Xnn3D0qqNVtOA

PPC shows:
http://www.google.com/aclk?sa=l&ai=CQk…%2B-%2BNational

([organic]url and [PPC]aclk)
I can use regex to implement it but how can i get those link by using piwik since i can only get the referer_url.

Thanks

Does anyone has any idea about that?
Or in another saying, can we track Adwords information from google by using Campaign and how?
Thanks.
