Consent Management for Multi-Domain and Multi-Brand Websites
Managing consent for a single website is straightforward. Managing it across multiple domains, subdomains, and brands — each with different audiences, languages, and regulatory requirements — is where most CMPs fall short. If your organisation operates more than one web property, your consent strategy needs to account for shared audiences, cross-domain tracking rules, and centralised compliance reporting.
The Multi-Domain Challenge
- Consent is per-domain — a visitor who consents on domain-a.com has not consented on domain-b.com
- Cross-domain tracking requires explicit consent on each domain separately
- Different domains may serve different markets with different regulations (GDPR, CCPA, LGPD)
- Brand consistency — banners should match each brand's design while maintaining compliance
Architecture Options
1. One CMP Account, Multiple Configurations
A single FlexyConsent account can manage consent for multiple domains. Each domain gets its own configuration — banner design, language settings, default consent state — while sharing a single dashboard for reporting.
2. Subdomain Sharing
For subdomains (shop.example.com, blog.example.com), consent can be shared across the parent domain, reducing banner fatigue for returning visitors.
Best Practices
- Configure each domain separately in your CMP panel
- Match banner design to each brand's visual identity
- Set default consent per domain based on primary audience geography
- Use the same TCF 2.3 and Consent Mode V2 integration across all domains
- Centralise compliance reporting in a single dashboard
