How domain groups actually work

In partnership with
Domain groups explained (finally)
Domain groups in consent tools can be confusing.
There's a lot of conflicting information out there about how cross-domain consent sharing actually works.
So we decided to clear it up.
What We Learned
Our team recently dove deep into how domain groups function in tools like Cookiebot.
The key insight? It's all about domain levels and browser security features.
Cross-domain consent sharing works beautifully between subdomains and main domains.
my.company.com to company.com? Perfect.
But separate domains like company.com to business.com? That's where browser security steps in.
Why This Matters
Understanding these distinctions helps you set realistic expectations.
And design better user experiences.
When you know what's possible, you can plan accordingly.
The Practical Benefits
Domain groups are incredibly useful for standardizing banner configuration across multiple properties.
One setup. Multiple deployments. Consistent experience.
Just with clear expectations about where consent transfers and where it doesn't.
What We Built
Manisha put together a comprehensive walkthrough showing exactly how this works.
She demonstrates the setup process, shows real examples, and explains the technical details that matter.
It's the kind of practical training that saves hours of trial and error.
Worth Your Time
If you're working with multiple domains or helping clients with consent management, this training will clarify a lot.
It's detailed but accessible. Technical but practical.
The kind of resource we wish we'd had when we were figuring this out ourselves.

Big investors are buying this “unlisted” stock
When the founder who sold his last company to Zillow for $120M starts a new venture, people notice. That’s why the same VCs behind Uber and eBay also backed Pacaso. They made $110M+ in gross profit to date. They even reserved the Nasdaq ticker PCSO. Now, you can join, too.
