If consent rates differ significantly between desktop and mobile, this is usually due to different banner displays. Mobile users see the cookie banner differently than desktop users, leading to varying consent rates. Furthermore, screen size plays a decisive role in the user’s decision. As a result, consent rates can differ by up to 30 percentage points.

Why Consent Rates Differ Between Desktop and Mobile

On mobile devices, the cookie banner often takes up the entire screen. Consequently, users feel more pressured to make a quick decision. Moreover, the decline button is often harder to find on mobile. As a result, consent rates differ significantly between desktop and mobile. More information can be found in our FAQ on analytics data loss.

Optimizing Banner Design for Better Mobile Consent Rates

The most important measure is a responsive banner design that works well on mobile devices. First, the accept button should be prominent and easily reachable. Additionally, it is recommended to limit the banner height on mobile so that the content below remains visible. As a result, consent rates differ less between desktop and mobile. Google offers best practices in the Consent Mode documentation.

Our Recommendation

We recommend testing and optimizing the cookie banner separately for mobile and desktop. First, analyze the current consent rates by device type in your CMP. Then, A/B testing different banner variants on mobile is advisable. Furthermore, a less intrusive design can significantly improve the consent rate.

Conclusion

In summary, different consent rates between desktop and mobile are normal. However, the gap can be significantly reduced with targeted banner optimization. Contact us for a banner UX analysis.
