The cookie banner sets the loading time for your whole page

A CMP loads before almost anything else, blocks tags until users decide, then releases scripts the moment they consent. Built without an eye on speed, all that weight lands on your performance scores.

Slower load times

A bulky banner blocks the page from painting and pushes back every script behind it. Your largest content loads later. Users wait, and so do search crawlers.

A hit to INP, a Core Web Vital

Google counts INP (Interaction to Next Paint) as a Core Web Vital. A heavy CMP makes your page slow to respond to the first tap or click, and that lands on a live ranking signal.

The SEO you can’t trace

Rankings slip, but the cause hides in plain sight. Almost nobody audits the cookie banner, so the one script dragging your scores is the one nobody checks.

A compounding revenue loss

Every month on a non-optimized banner, the lost revenue grows. The good news: it’s fully recoverable, if your CMP is built for speed, not just legal sign-off.

What changes when your CMP is built for performance

Load consent in milliseconds, not seconds

consentmanager loads asynchronously from EU servers with CDN hubs across regions, keeping latency under 200ms wherever your visitors are. The banner appears fast and your other scripts aren’t held in the queue, so your Core Web Vitals stay healthy.

See exactly what’s slowing you down

The Compliance Monitor includes page timing analysis that flags the third-party scripts dragging your pages. You see what’s adding weight, why it matters, and how to fix it, instead of guessing.

Improve consent rate and conversions

Run A/B tests on the banner with machine learning that shifts traffic to the best design automatically. It can help you lift consent rates while keeping the experience light, with no trade-off between performance and opt-ins.

“consentmanager proved to be the only compliance solution that truly digs deep and delivers clear, actionable reports that each of our teams, under different Business Units and regions, can easily use. Compared to six months ago, we’ve significantly reduced compliance gaps by 60%, improving month by month.”

Carlos Roda

CTO, Refinery89

“Managing consent across more than 1,000 sites manually was never going to scale. consentmanager gave us the tools to handle configuration, updates, and reporting across our entire network from one place, without adding headcount.”

Daniel Tschirschwitz

Head of Performance Tracking & IT, Smarketer

“Managing consent across a large client portfolio used to be a constant headache. With consentmanager, we handle it from one place, and the impact on data quality across our accounts has been clear.”

Jakub Novotný

Identity Solutions Manager, Seznam

“When we decided to deprecate our CMP for external publisher partners, our priority was making the transition as easy as possible. Switching from a free solution we provided since 2018 was a very sensitive topic. consentmanager by iubenda gave them everything they needed to get started for a fair price, and more than they had before.”

Marc Hofer

BSH Hausgeräte

“We weren’t solving a problem, we were making a smart upgrade. consentmanager brought capabilities we couldn’t justify building in-house, and took the maintenance burden completely off our plate.”

The performance impact, side by side

Without a performance-focused CMP

A heavy banner blocks rendering and pushes back every script. INP and LCP scores drop. Search ranking takes a quiet hit you can’t trace. Slow pages lift bounce rates. The performance debt compounds every month.

With consentmanager

Lightweight, async banner code that loads in under 200ms. EU servers with regional CDN hubs to cut latency. Page timing analysis that pinpoints slow scripts. A/B testing to lift consent without weighing the page down. Core Web Vitals protected, not sacrificed.

What web and SEO teams ask before switching

Yes. It’s often the first element to load and it controls many of your scripts, so its speed feeds straight into your Core Web Vitals, which Google uses to rank you. A fast banner helps protect those scores.

No. Compatibility Mode keeps your existing blocking logic, dataLayer events, and custom scripts intact, and integrates natively with Google Tag Manager and Consent Mode v2. Most teams migrate in days.

Most CMPs treat the banner as a legal artifact. consentmanager is built around performance: async loading, page timing analysis, and A/B testing, alongside full regulatory coverage.

EU-only data storage by default. Aligned with GDPR, CCPA, ePrivacy, IAB TCF v2.3, and Google CMP Partner requirements.

Stop losing speed. Start ranking on a faster site.

consentmanager keeps your pages fast, protects your Core Web Vitals, and stays aligned with regulations, all from one lightweight banner. Join the brands treating consent as a performance win, not a drag.
