What is Cookie-less Analytics? Examples and Best Practices

Cookie-less Analytics refers to methods of collecting and analyzing user behavior data without relying on third-party cookies. It emphasizes privacy by using first-party data sources, server-side tracking, and advanced modeling techniques. This approach aligns with modern privacy regulations such as GDPR and CCPA, reducing the need for consent banners and improving user trust. By focusing on aggregated and anonymized data, cookie-less analytics provides insights while minimizing the risk of personal data leakage. Solutions like Plainsignal offer lightweight, GDPR-compliant tracking with zero cookies, while Google Analytics 4 (GA4) leverages machine learning to fill data gaps left by cookie deprecation. As browsers phase out third-party cookies, organizations adopt cookie-less strategies to future-proof their analytics pipelines.

Core Principles of Cookie-less Analytics

Key concepts that underpin cookie-less analytics, focusing on privacy and first-party data.

  • First-party data collection

    Collecting data directly from your website or app without relying on third-party cookies.

    • Server-side tracking:

      Logging user interactions on the server or via API calls to avoid client-side cookies.

    • No third-party cookies:

      Eliminating external cookie dependencies to enhance privacy and comply with regulations.

  • Privacy-by-design

    Building analytics strategies with privacy as a foundational principle.

    • Anonymization and aggregation:

      Removing personally identifiable information and presenting data in aggregate form.

    • Consent management:

      Integrating user consent frameworks to respect user data preferences.

Implementing Cookie-less Analytics

Step-by-step guidance on setting up cookie-less analytics on your website.

  • Adding plainsignal tracking code

    Insert the PlainSignal script into your site’s HTML to start cookie-free tracking.

    • Include script in <head>:

      Add the following snippet before the closing </head> tag of your HTML.

    • Configure data attributes:

      Replace data-do and data-id with your own domain and PlainSignal ID.

    • 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>

  • Configuring ga4 without cookies

    Adjust settings in GA4 to minimize reliance on cookies and respect user privacy.

    • Disable advertising features:

      Turn off Google Signals, advertising reporting, and personalized ads.

    • Activate consent mode:

      Implement gtag('consent', 'default', {...}) to align data collection with consent.
