Three numbers every marketer should know before their next budget review
Up to
70%
of conversion data can disappear when consent isn’t managed for performance.
30 to
60%
of users never interact with cookie banners, leaving silent blind spots in
your data.

average lift
in trackable conversions for brands that A/B test their consent banner.
The cookie banner decides what your marketing stack can see
Every tag and pixel waits for a yes from the cookie banner. When users reject or ignore it, your measurement stack goes dark, even as traffic and conversions keep coming in. That’s the gap between a campaign that looks like it’s failing and one that’s actually working.
Broken attribution
Without consent, pixels from Google Ads, Meta, and LinkedIn can’t fire. Last-click breaks. Multi-touch breaks harder. You cut what’s working and double down on what isn’t.
Remarketing collapse
Your highest-ROAS audiences are built from tracking pixels. Without consent, those pools shrink. Same creative, weaker results.
Reporting gaps
Dashboards drop 30 to 70% in visible conversions, not because revenue fell, but because consent blocked the data. The danger isn’t the loss. It’s the illusion, and you fix the wrong thing.
Every quarter you wait, the gap compounds. The good news: every loss is recoverable, if your CMP is built for performance, not just legal sign-off. We’ll look at your current setup, the consent rate you’re working with, and where the recoverable upside actually is.
What changes when consent is treated
as a conversion lever
Most CMPs ship a banner and stop there. consentmanager gives marketing teams the tools to recover lost data, lift consent rates, and feed a cleaner signal back into your stack.
Lift consent rates by testing your banner like any other funnel step
consentmanager is one of the few CMPs with built-in A/B testing on the banner itself. Test design, copy, and tone to find what lifts consent, while staying aligned with privacy rules.
Why it matters: Every percentage point of consent you recover flows straight into your attribution, remarketing pools, and reporting.
Recover the data that denied users would have cost you
Native Google Consent Mode v2 integration sends anonymized signals from denied users, and conversion modeling fills in the gaps. One-click setup, no manual tag rewiring.
Why it matters: You recover a meaningful share of the 30 to 70% data loss without rebuilding your tag setup or compromising on consent.
Manage consent like a funnel metric, not a compliance checkbox
consentmanager surfaces consent data where marketers need it: opt-in rates by country, device, traffic source, and banner variant, tracked over time. See where consent is leaking, which markets need a different approach, and whether your last banner change moved the number.
Why it matters: You stop guessing at consent rates and start making budget and design decisions on real data.

What enterprise marketing teams ask before switching
How long does migration take?
Most teams migrate in days, not weeks. Our team handles the heavy lifting and matches your existing setup so you don’t lose continuity.
Will this break my GTM or tag setup?
No. consentmanager integrates natively with Google Tag Manager and Consent Mode v2. Existing tags keep firing exactly as configured, just tied to the right consent signals.
How does this compare to OneTrust or Cookiebot?
Most CMPs treat the banner as a legal artifact. consentmanager is built around marketing performance: A/B testing, consent analytics, and conversion recovery, alongside full regulatory coverage.
Where is the data stored?
EU-only data storage by default. Aligned with GDPR, CCPA, ePrivacy, IAB TCF v2.3, and Google CMP Partner requirements.
