Piwik detects URLs tagged with Google Analytics campaign parameters. Piwik offers two dimensions for Campaign tracking: name, and keyword.

The campaign parameter (in this order: utm_campaign, or utm_medium, or utm_source) is used as the Campaign name.

The parameter utm_term is used as the Campaign keyword.

Learn more about Tracking Campaigns in Piwik or head over to the URL Builder. Advanced users may also choose to customise campaign parameters detected by Piwik.

Note: you can use campaign parameters in the query string (landing?utm_campaign=PaidSearch), and Piwik also detects campaign and keyword in the hash tag string (landing.html?q=test#utm_campaign=PaidSearch)
