Piwik detects URLs tagged with Google Analytics campaign parameters. By default, Piwik offers two dimensions for Campaign tracking: name, and keyword. The parameters
utm_source are used as the Campaign name. The parameter
utm_term is used as the Campaign keyword. You can learn more about Tracking Campaigns in Piwik or head over to the URL Builder.
If you need to track more than two campaign dimensions in Piwik, for example if you want to enjoy the same campaign reporting as in Google Analytics, you can install the MarketingCampaignsReporting plugin available here on the Marketplace. The Marketing Campaigns Reporting plugin lets you track up to five Campaigns parameters (name, source, medium, keyword, content).
* you may choose to customise campaign parameters detected by Piwik.
* 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
