Why Kartra Funnels Need a Cookie Banner
Kartra sets tracking cookies the moment a visitor lands on your funnel page. These first-party cookies power affiliate attribution, visitor analytics, and session management across your entire sales flow - from opt-in pages through checkout and into membership areas.
Under Article 5(3) of the ePrivacy Directive and the GDPR, storing or accessing information on a visitor's device requires prior consent - unless the cookie is strictly necessary for the service the visitor requested. Kartra's analytics and affiliate tracking cookies do not qualify as strictly necessary.
That distinction matters. European data protection authorities issued record fines throughout 2024 and 2025 for cookie consent violations, with CNIL alone handing down multiple six-figure penalties to organisations that loaded tracking scripts before obtaining consent.
What Cookies Does Kartra Set?
Kartra splits its cookies into two categories: essential and optional. The essential cookies handle login sessions for membership areas, helpdesk authentication, and remembering a visitor's consent choice. Optional cookies track visitor behaviour across funnel steps, attribute conversions to affiliates, and feed Kartra's built-in analytics dashboard.
If a visitor accepts only essential cookies, Kartra still functions - membership logins work, checkout processes complete, and the helpdesk stays accessible. Affiliate tracking, cross-page analytics, and personalised funnel behaviour stop.
Here is a breakdown of common cookies you will find on a typical Kartra funnel:
| Cookie | Type | Purpose | Consent Required |
|---|---|---|---|
__kts | Tracking | Visitor identification across funnel pages | Yes |
__ktv | Tracking | Visit attribution and analytics | Yes |
__kta | Tracking | Affiliate referral tracking | Yes |
XSRF-TOKEN | Essential | Cross-site request forgery protection | No |
kartra_session | Essential | Session management and login state | No |
cookie_consent | Essential | Stores the visitor's consent preference | No |
If you also embed third-party scripts - Google Analytics 4, Meta Pixel, or TikTok Pixel - those add their own cookies on top of Kartra's defaults.
Kartra's Built-in GDPR Banner vs a Dedicated CMP
Kartra includes a built-in cookie disclaimer banner that appears at the bottom of pages when you enable the GDPR and CCPA settings. It links to your cookie policy and privacy policy pages.
The built-in banner has limits. It does not block tracking cookies before consent. It does not sort cookies into granular categories (analytics, marketing, functional). It offers no mechanism for visitors to accept some cookie types while rejecting others. Under current enforcement standards, a banner that informs without blocking fails to meet the prior consent requirement set out in the ePrivacy Directive.
A dedicated consent management platform handles what Kartra's built-in option cannot: script blocking before consent, granular cookie categories, consent logging with timestamps, and automatic geo-detection so your banner adapts to the visitor's jurisdiction.
How to Install a Cookie Banner on Kartra
Kartra supports custom code injection through its tracking code settings, which means you can add any third-party cookie banner script to your funnel pages. The installation process takes a few minutes per page or can be applied globally through your account settings.
Step 1: Get Your Banner Script
After setting up your cookie banner configuration (categories, colours, consent text), copy the installation script. This is typically a single <script> tag that loads asynchronously in the page header.
Step 2: Add the Script to Kartra Pages
Open your funnel page in the Kartra page builder. Go to Settings, then select the Tracking Code option. Paste your cookie banner script into the header code field and click Apply. Repeat this for each page in your funnel - opt-in pages, sales pages, checkout pages, and thank-you pages all need the same snippet.
Step 3: Cover Membership Areas
Membership pages use a separate code injection point. Navigate to your membership site settings and add the same script to the header tracking code section. This ensures logged-in members see the cookie banner and can manage their preferences.
Step 4: Verify the Installation
Preview each page type in your funnel. Check that the banner appears, that rejecting cookies actually prevents tracking scripts from firing, and that the consent preference persists across page navigations. The Kartra installation guide in the Help Centre walks through each step with screenshots.
Handling Third-Party Scripts in Kartra Funnels
Most Kartra users add external tracking scripts for advertising and analytics. Each of these scripts sets its own cookies and must be blocked until the visitor grants consent for that category.
A properly configured cookie banner uses conditional script loading to hold back non-essential scripts. When a visitor accepts marketing cookies, the banner releases _fbp (Meta Pixel) and _ttp (TikTok Pixel). When they accept analytics cookies, _ga and _ga_* (Google Analytics 4) begin tracking.
If you use Google Tag Manager to manage your Kartra tracking, Google Consent Mode v2 lets GTM fire tags conditionally based on the visitor's consent state. This preserves conversion modelling in Google Ads even when a visitor declines analytics cookies.
Which Regulations Apply to Your Kartra Funnels?
The answer depends on where your visitors are, not where your business is based. A funnel targeting UK customers falls under UK GDPR and PECR regardless of whether your Kartra account is registered in the United States. A funnel with California traffic triggers CCPA obligations once you meet the revenue or data volume thresholds.
The practical differences between jurisdictions affect how your banner should behave:
| Regulation | Consent Model | Default Cookie State | Reject Button Required |
|---|---|---|---|
| GDPR / ePrivacy | Opt-in | Blocked until consent | Yes - equal prominence |
| UK GDPR / PECR | Opt-in | Blocked until consent | Yes - equal prominence |
| CCPA / CPRA | Opt-out | Active by default | "Do Not Sell" link required |
| LGPD (Brazil) | Opt-in | Blocked until consent | Yes |
| PIPEDA (Canada) | Opt-in (implied for non-sensitive) | Varies | Recommended |
Geo-detection solves this automatically. When a visitor from Germany loads your funnel, they see an opt-in banner with a clear reject button. A visitor from Texas sees an opt-out notice with a "Do Not Sell My Personal Information" link. The Kukie.io features page covers how geo-detection, cookie scanning, and script blocking work together.
Common Mistakes with Kartra Cookie Consent
Adding a banner to only the first funnel page is the most frequent error. Visitors who land directly on a checkout page via an email link bypass the opt-in page entirely and never see the banner. Every page in the funnel needs the script.
Forgetting membership areas is another gap. Membership sites set session cookies (essential) but also track page views and course progress (analytics). Without a banner, those analytics cookies load without consent.
Relying on Kartra's built-in GDPR toggle alone creates a false sense of compliance. The toggle enables a disclosure banner and consent checkboxes on opt-in forms, but it does not block cookies before consent - the core technical requirement under EU and UK law.
Pre-ticking cookie categories is non-compliant under GDPR. The EDPB confirmed in its 2020 guidelines on consent that pre-selected options do not constitute freely given consent.
Scanning Your Kartra Funnel for Cookies
Before configuring your banner categories, run a cookie audit on each page type in your funnel. A cookie scanner crawls the page, identifies every cookie set by first-party and third-party scripts, and maps each one to a category.
This step catches cookies you might not know about - embedded video players, live chat widgets, payment gateway iframes, and social sharing buttons all set their own cookies. The cookie scanning documentation explains how automated scans detect and categorise these.
Frequently Asked Questions
Does Kartra have a built-in cookie consent banner?
Kartra includes a basic cookie disclaimer banner when you enable its GDPR and CCPA settings. It displays links to your cookie policy and privacy policy but does not block non-essential cookies before consent, which is required under EU and UK privacy law.
Do I need cookie consent on every Kartra funnel page?
Yes. Each page in your funnel - opt-in, sales, checkout, thank-you, and membership - must display the cookie banner. Visitors can land on any page directly, so every page needs the consent mechanism.
What happens to Kartra affiliate tracking if a visitor rejects cookies?
If a visitor rejects optional cookies, Kartra's affiliate tracking cookie is not set. The affiliate referral will not be recorded for that visit. This is the expected behaviour under GDPR - tracking requires consent.
Can I use Google Tag Manager with Kartra and cookie consent?
Yes. Add GTM through Kartra's tracking code settings, then configure Google Consent Mode v2 so tags fire only after the visitor grants consent for the relevant category.
How do I add a cookie banner to Kartra membership pages?
Navigate to your membership site settings in Kartra and paste your cookie banner script into the header tracking code section. This is separate from the funnel page tracking code and must be added individually.
Is Kartra's GDPR checkbox on opt-in forms enough for cookie compliance?
No. The GDPR checkbox collects consent for data processing at the point of opt-in, but it does not control cookie behaviour. You still need a cookie banner that blocks non-essential cookies before consent.
Take Control of Your Cookie Compliance
If you are not sure which cookies your Kartra funnels set, start with a free scan. Kukie.io detects, categorises, and helps you manage every cookie - so your visitors get a clear choice, and you stay on the right side of the law.
