Tracking Pixel & UTM Troubleshooting

Common issues with the ContactLevel tracking pixel and cl_audience parameter, and how to fix them.

Pixel Not Tracking Visits

  • Verify the pixel script is in the <head> section of every page

  • Check for tag manager issues (use preview/debug mode)

  • Test in incognito mode to rule out ad blockers

  • Check pixel status in ContactLevel dashboard

cl_audience Parameter Not Working

  • Verify format: cl_audience=YOUR_AUDIENCE_ID

  • Check for duplicate ? in the URL

  • Verify the audience ID matches your ContactLevel dashboard

  • Check platform-specific setup: LinkedIn (campaign-level URL tracking), Meta (ad-level URL params), Google (tracking template with {lpurl}), Reddit/X (direct in destination URL)

Pixel Installed but No Contact-Level Data

  • You need both the pixel and the cl_audience parameter

  • Check that every ad includes the cl_audience parameter

  • Allow a few hours for data to appear

Parameter Getting Stripped

  • Check CMS settings for URL parameter handling

  • Check for JavaScript/SPA URL rewrites

  • Test with a simple HTML page to isolate the issue
