CentroProfits offers the ability to use a comma-separated list of traffic tags to segment one campaign. Traffic tag is a key word which is used by webmasters to optimize search results for the link. You just need to add a special /t/ directory to your referral URL and put any tags (0-9,a-z,A-Z). Here's the structure example:
site.com/r/RefCode/t/tag1,Tag2,tAg3,taG4,tagN/join (for a deep linking)
Traffic tags won't be shown in campaigns list, however you will be able to get statistics by tag in the Profit & Loss report.
