On24 - Webinar & Virtual Event Data Consent

Overview

On24 is a B2B webinar and virtual event platform used by enterprise marketing teams for demand generation, product launches, and thought leadership events. Its scripts embed registration forms, webinar console players, and virtual event portals on corporate marketing sites, collecting extensive attendee data that feeds into marketing automation and sales follow-up workflows.

What This Script Does

On24's embeddable components provide:

Registration forms: Collect attendee contact details (name, email, company, job title, custom fields) and submit them to On24's registration servers. Data is frequently synced to connected CRM and marketing automation platforms.
Webinar console: Renders the live/on-demand webinar player with interactive elements — polls, Q&A panels, resource downloads, and chat. Each interaction is logged as an engagement event.
Engagement tracking: Records granular attendee behavior — session join/leave times, poll responses, questions asked, resources downloaded, and content engagement duration. This data powers the "engagement score" used for lead qualification.
Cookies: Sets cookies for session management, registration state persistence, and source attribution (UTM parameters, referrer tracking).
Marketing integration: Registration and engagement data is synced to Salesforce, Marketo, HubSpot, and other platforms for automated lead scoring and follow-up campaigns.

Consent & Compliance

On24 operates in a mixed functional/marketing consent category. Event delivery is functional, but the engagement tracking and marketing platform integrations serve marketing purposes.

Under GDPR and ePrivacy, registration forms collect personal data requiring a lawful basis under GDPR Article 6. Cookies for source attribution are non-essential. The detailed engagement scoring and data forwarding to marketing platforms require transparency and consent.

Under CCPA/CPRA, attendee data shared with marketing platforms constitutes processing personal information for marketing purposes.

Should You Block This Without Consent?

Conditional. The event registration and webinar delivery are functional when the visitor initiates them. However, source attribution cookies and data forwarding to marketing platforms should be gated behind marketing consent. Load the basic event interface without tracking parameters, and enable marketing integrations after consent.

Frequently Asked Questions

Does On24 require cookie consent on my website?

Conditionally, yes. On24's event registration is functional, but it sets attribution cookies for UTM and referrer tracking, and syncs engagement data to marketing platforms like Salesforce and HubSpot. The engagement scoring and marketing integrations require consent under GDPR and ePrivacy regulations.

What data does On24 collect from webinar attendees?

On24 collects registrant details (name, email, company, job title), session duration, poll responses, Q&A activity, and resource downloads. It sets cookies for session state and source attribution. Engagement data generates lead qualification scores synced to CRM and marketing automation platforms.

How does ConsentStack manage On24 scripts?

ConsentStack detects On24 embeds and classifies them under the marketing category. Without consent, attribution tracking and marketing integration scripts are blocked while basic registration forms remain functional. Full engagement tracking and CRM syncing activate only after consent is given.
