If you’re running multiple storefronts under different subdomains, you know how repetitive cookie banners can create friction for your visitors. A customer lands on your main domain, accepts cookies, then heads to another country store - only to get hit with the same banner again. That’s not just annoying, it’s also a missed opportunity.

Consent fatigue is real. When shoppers have to click through the same prompts over and over, some will drop off. Others will skip giving full consent altogether. But what if there was a way to collect consent once - and apply it everywhere across your brand?

Now there is. Say hello to Cross-Domain Consent, the latest feature from Consentmo built to help merchants with multiple subdomains deliver a smoother, smarter privacy experience.

What Is Cross-Domain Consent?

Cross-domain consent allows you to apply a visitor’s cookie preferences across all your store’s subdomains. That means when someone consents to cookies on store.com, that same consent applies to de.store.com, uk.store.com, and any other subdomain you’ve linked.

Instead of showing multiple banners and collecting multiple consents, the system remembers the user’s choice and applies it automatically. All domains stay compliant, and the visitor enjoys a cleaner, more consistent experience.

This only works when your domains are properly connected behind the scenes. That’s why Consentmo now gives you an easy way to link them from inside the app.

Why Cross-Domain Consent Matters

If you have more than one subdomain, asking for cookie consent multiple times can cause more harm than good. Repetitive banners slow people down, interrupt the browsing journey, and create doubt. Visitors may not understand why they’re seeing the same message again - or they may just leave.

Cross-domain consent reduces those risks. When visitors give permission once, they don’t have to think about it again. That means:

• No more duplicate banners across your sites
• Better data accuracy by capturing full consent signals
• Faster browsing from page to page or store to store

It’s also helpful for maintaining clear privacy practices. Consentmo still displays the list of connected subdomains on the banner. That way, users always know what they’re agreeing to.

Consentmo’s Cross-Domain Consent Sharing: How It Works

We built this feature for Enterprise merchants who manage multiple stores under a main domain. With Cross-Domain Consent Sharing, your visitors only need to interact with the cookie banner once - on any of your subdomains.

Once they accept, we automatically:

• Extend those permissions to all linked subdomains
• Avoid triggering banners again for that session
• Log the consent event in your Consent Records for tracking

Everything is managed from one place. Just go to:

Settings → General Settings → Cross-domain consent sharing

From there, you can:

• Add or remove subdomains from the shared group
• Review connected domains
• Enable the feature with a simple toggle

No additional coding or banner configuration is needed. Once set up, the app handles the rest.

This feature is available exclusively for Enterprise plan users. It’s ideal for larger stores with regional storefronts, language-specific domains, or international brand branches.

Why Merchants Are Turning It On

We’ve already seen great results from early adopters. Stores using Cross-Domain Consent report:

• Higher consent completion rates across all markets
• Lower drop-off rates when customers navigate between country sites
• Fewer duplicate records in consent logs

For merchants, this means a cleaner compliance strategy. For visitors, it means a smoother experience. And for your business, it means better data and fewer obstacles on the path to conversion.

Wrapping Up

Cross-Domain Consent is one of those behind-the-scenes tools that can make a big difference in how users experience your brand. With one feature, Consentmo helps you reduce distractions, capture more accurate data, and keep your subdomains working as one.

If you’re on the Enterprise plan, this new tool is ready to go.

Let your users say “yes” once - and get on with shopping.
