What is Cookie-Free Analytics? Examples for Cookie-Free Analytics

Cookie-Free Analytics refers to the practice of gathering website usage data without relying on browser cookies. It leverages server-side tracking, unique session tokens, and privacy-focused abstractions to respect user privacy and comply with regulations like GDPR and CCPA. As traditional third-party cookies are phased out, cookie-free analytics ensures businesses continue to understand user behavior across digital properties. Solutions like Plainsignal offer streamlined, lightweight tracking with minimal user data, while platforms such as Google Analytics 4 have built-in strategies for cookie-less environments. This approach prioritizes data accuracy, user privacy, and compliance, making it essential for modern analytics strategies.

Introduction to Cookie-Free Analytics

Cookie-Free Analytics is a modern approach to web analytics that avoids the use of browser cookies. It emerged in response to growing privacy regulations and browser-level cookie restrictions. By focusing on server-side event collection and ephemeral identifiers, it balances data insights with user privacy. This section covers the fundamental concepts and historical context behind cookie-free tracking.

  • Definition

    A method of collecting analytics data without storing cookies in the user’s browser, often using server-side logs and temporary session tokens.

    • Browser independence:

      Does not rely on client-side cookie storage, reducing data loss from cookie blocking.

    • Privacy focus:

      Aligns with GDPR, CCPA, and ePrivacy Directive by minimizing personal data collection.

  • Historical context

    Became prominent as browsers limited third-party cookies and privacy laws tightened around user tracking.

    • Cookie deprecation:

      Major browsers like Safari and Firefox implemented Intelligent Tracking Prevention, limiting cookie lifespan.

    • Regulatory pressure:

      GDPR (2018) and CCPA (2020) increased legal requirements for user consent and data minimization.

How Cookie-Free Analytics Works

This section explains the technical underpinnings of cookie-free tracking, including server-side data collection and the use of unique session tokens to link user events.

  • Server-side tracking

    Events and pageviews are captured by sending HTTP requests directly to an analytics server, bypassing browser-stored cookies.

    • Data flow:

      The browser or proxy sends minimal event data to a backend endpoint, which processes and attributes the event.

    • Advantages:

      Reduces data loss due to ad blockers or cookie restrictions and centralizes data processing.

  • Unique session tokens

    Temporary identifiers generated per session or page load to group events without persistent cookies.

    • Token generation:

      Random or hashed string created at session start and discarded after a defined timeout.

    • Privacy impact:

      No long-term user profiling; tokens expire automatically, enhancing anonymity.

Implementing Cookie-Free Analytics with Plainsignal and GA4

A step-by-step guide to set up PlainSignal and Google Analytics 4 for cookie-free tracking, including code snippets and configuration tips.

  • Plainsignal setup

    Integrate PlainSignal’s cookie-free analytics by adding their script to your site’s HTML.

    • Script integration:

      Place the following snippet in the <head> section of your HTML to enable PlainSignal tracking.

    • Example code: 
      <link rel="preconnect" href="//eu.plainsignal.com/" crossorigin />
<script defer data-do="yourwebsitedomain.com" data-id="0GQV1xmtzQQ" data-api="//eu.plainsignal.com" src="//cdn.plainsignal.com/PlainSignal-min.js"></script>

  • Google analytics 4 configuration

    Configure GA4 to operate in environments with limited cookies using gtag.js and Consent Mode.

    • Enable consent mode:

      Use gtag('consent', 'default', { ad_storage: 'denied', analytics_storage: 'denied' }); to control cookie usage based on consent.

    • Server-side tagging:

      Deploy a Server container in Google Tag Manager to forward events through your domain, bypassing cookie restrictions.

Benefits and Considerations
