Separate AdWords visitors

Hi, so far I have only found similar posts here but not what I’m looking.
So, I want to know if you can come through AdWords, recognize visitors and can output separately, eg Visitors of a external website or something. To simply know who comes from search engines (organic results) and who comes through advertising (AdWords), etc…

I would not go so far as to make any changes in the AdWords itself, so I can evaluate campaigns in Piwik.
It’s simple separation from the “free” visitors and “paid” (AdWords) visitors.

That would still be possible through the URL-Refer, or similar.

best regards

If you use Piwik 2.0-beta it should automatically put the visitors in the “adwords” category if an adword URL was found in the referrer. Does it help?
