What Is Registration Source?

Registration source refers to the channel, link, or promotional pathway through which an individual registers for a webinar or virtual event. On the ON24 Intelligent Engagement Platform, registration source is typically identified using URL parameters appended to the registration or audience link. These parameters allow marketers to understand exactly where registrants are coming from—whether that’s email, social media, paid campaigns, partner promotions, or owned channels.

ON24 captures and reports these sources so teams can evaluate performance across campaigns and determine which channels generate the highest volume of registrants and, eventually, attendees.

Why It Matters

Understanding registration source is essential for optimizing event promotion. It provides clear visibility into which channels work best for attracting the right audiences and which may require messaging or targeting adjustments. Registration source also helps quantify ROI for paid promotions and measure the effectiveness of organic channels.

This insight is especially important for webinar-heavy strategies, where recurring and ongoing events rely on consistent audience acquisition. Knowing which channels deliver high-quality registrants helps teams refine future promotional plans and invest in the most successful pathways.

Registration source data also feeds broader engagement strategies. When paired with content interaction patterns—like those described on the Propel Your Pipeline page—these insights help identify which audiences respond best to certain content types, topics, and messaging.

How It’s Used

  • Campaign Attribution: Marketing teams append URL parameters to outbound promotions so ON24 can track where registrants originate (e.g., “email,” “social,” “paid-media,” “partner”). This helps determine which channels drive the best performance.
  • Audience Segmentation: Registration source helps differentiate between audience segments. For example, social media registrants may show different engagement behaviors than email-driven registrants.
  • Promotion Optimization: By comparing registration sources across programs or events, teams can make informed decisions about where to increase or reduce promotional investment.
  • Partner And Co-Marketing Measurement: For webinars promoted through partners or sponsors, registration source tracking identifies how many registrants each partner contributed.
  • Forecasting And Planning: Recurring webinar programs often rely on registration source data to refine cadence, messaging, and promotional timing. Example programs can be explored on the Upcoming Webinars page.

Key Benefits

  • Improved Campaign Insight: Shows which marketing channels generate the most registrants.
  • Better Resource Allocation: Helps teams focus on high-performing promotional pathways.
  • Audience Behavior Understanding: Reveals how different traffic sources impact engagement.
  • Stronger ROI Measurement: Supports attribution for paid and partner-driven campaigns.
