Frequently Asked Questions
What is cross-domain consent?
Cross-domain consent allows organisations to capture consent once and apply it across multiple related websites. Cross-domain consent management helps maintain consistent preferences across digital properties without repeated prompts.
How do you manage consent across multiple domains?
Consent is captured centrally and synchronized across connected domains using shared identifiers or first-party mechanisms, ensuring preferences are recognized wherever users interact.
Can consent preferences be shared between websites?
Yes. With multi-domain consent, preferences can be shared across related domains, reducing repetition and improving consistency in how consent is applied.
How does cross-domain consent work with browser restrictions?
Modern cross-domain consent management uses first-party techniques and secure identifiers to work within browser privacy restrictions, avoiding reliance on third-party cookies.
Is cross-domain consent compliant with GDPR?
Yes, when implemented correctly. Consent must still be informed, specific and auditable, with clear records showing how and where it was collected and applied.
Does this work without third-party cookies?
Yes. Cross-domain consent can operate using first-party data and identity-based approaches, making it suitable for privacy-first environments.
How do you maintain user experience across domains?
By reducing repeated consent prompts and applying consistent preferences, cross-domain consent helps create smoother, more continuous user journeys.
Can consent sync across subdomains and external domains?
Yes. Consent sync can work across both subdomains and approved external domains, depending on how systems and identifiers are configured.
What are the risks of not managing cross-domain consent?
Without proper consent sync, users may see repeated banners which disrupts the user and buying journey. Also preferences may be inconsistently applied and organizations risk non-compliant data usage.
How do you implement cross-domain consent technically?
It is typically implemented using shared consent records, first-party identifiers and API-based consent sync across connected domains and systems.
