The Ur-Text Simple Landing Tracking plugin lets you see where visitors to your WordPress pages are coming from.  When visitors land on your site by clicking links with your UTM codes (or navigate through your site internally using UTM-coded links), the request is tracked so you can see how many people are clicking those links.
If you use social media autoposting services like Sendible or Dlvr.it, you can create custom RSS feeds with UTM coded links so you can track all visitors from a specific source.
Also lets you create your own custom non-UTM code for tracking.
Features: 
– Plugin uses no cookies and retains no information about specific visits 
– All stored information is completely anonymous 
– Basic bot and crawler filtering removes bots from your visitor statistics 
– Automatically deletes old data 
– Report showing breakdown of landings 
– Download stats in .csv format
