Cookie Consent
The explicit permission obtained from website visitors before setting non-essential cookies on their devices, as required by privacy regulations like GDPR and ePrivacy.
Why cookie consent matters
Most analytics tools rely on cookies for user identification and tracking. Cookie consent requirements mean you can only set these cookies after the user explicitly agrees, creating a gap between total visitors and tracked visitors.
Consent rates vary by region (30-80%) and implementation quality. Understanding your consent rate is essential for accurate traffic and conversion analysis.

How to Track in KISSmetrics
Track consent_granted and consent_denied events. Measure your consent rate (consented / total visitors) by region, device, and traffic source. This tells you what percentage of your actual traffic you are capturing in analytics.
Common Mistakes
- -Auto-checking all consent categories as the default option
- -Making the reject button harder to find than the accept button
- -Not categorizing cookies properly - analytics, marketing, and functional cookies have different consent requirements
Pro Tips
- +A/B test your consent banner design to maximize opt-in rates while remaining compliant
- +Use cookieless tracking or server-side methods as a fallback for users who decline cookies
- +Track your consent wall drop-off - some users leave rather than making a choice
