Cookieless tracking is a method that gathers user data without relying on browser cookies. Instead, it uses methods like server-side tracking, first-party data, fingerprinting, and contextual targeting to understand behavior while ensuring privacy compliance. This approach helps businesses adapt to stricter regulations, improve data accuracy, and reduce dependence on third-party cookies.
In this blog post, we'll break down the concept of cookieless tracking, explain why it's essential, and provide tips on using it in your next marketing campaign. Take a few moments to put aside everything else you're working on - by discovering tracking without cookies, you may find new insights about your target audiences that will ultimately allow you to make smarter business decisions. Let's dive in!
Cookies are small text files containing bits of data used to identify a user's computer while browsing a network. Certain cookies are designed to recognize individual users and enhance their web experience.
Сookies make browsing the web a more seamless and unique experience for users.
Here are some reasons why cookies are important and why they exist:
Cookies exist to enhance the user experience on websites and to enable website owners to collect data that can be used to improve their services and marketing efforts. While there are some privacy concerns related to cookies, which we'll describe further, they are an essential part of the modern web.
Cookies help track user behavior, personalize content, and support ad targeting. But they also come with serious concerns.
Privacy issues. Cookies can help track users across multiple websites. This helps advertisers build detailed profiles, which many users find intrusive.
Security risks. Some cookies store sensitive data, like login tokens or payment-related info. If stored on the browser, this data can be accessed by third-party scripts, browser extensions, or malicious programs running on the user’s side.
Malicious cookies. Though rare, cookies can be used to deliver malware to a user’s device.
Browser restrictions. Safari and Firefox are now blocking third-party cookies by default. Safari’s Intelligent Tracking Prevention (ITP) limits all commercial first-party cookies to 1–7 days. That means even if someone returns after 24 hours, Safari may treat them as a brand-new user.
If your site sells high-ticket items or requires multiple visits before conversion, this makes tracking nearly impossible. You can compare the difference by checking how many returning users show up in Safari vs Chrome inside GA4.
GA4 is marketed as privacy-focused, and it is meant to function with or without cookies. GA4 can cover the data collection gaps as the world grows less reliant on cookies by utilizing machine learning and statistical modeling.
With browsers such as Safari and Firefox restricting third-party cookies, you can configure Google Analytics 4 to depend on first-party cookies by transitioning to server-side GA4 tracking. Mapping tagging server URL with a custom domain establishes 1st party cookies, which are more dependable and have a longer lifespan than 3rd party cookies.
Hosting server-side setups through platforms like Google Cloud can get costly and complicated. That’s why many marketers prefer managed services like Stape, which offers a free tier for up to 10,000 requests and paid plans starting at $20/month. You skip infrastructure work and start tracking right away.
You can set up GA4 tracking without utilizing any cookies, be it 1st or 3rd party, by using Stape's Advanced GA4 tag. This allows for purely server-side GA4 tracking.
And as for the Facebook solution - Facebook Conversions API and Conversions API Gateway - it can be said that besides cookies, it relies on user data. With the help of user parameters you send together with FB CAPI events, FB will match events to users in their database. As a result, you will have more reliable data and do not rely on cookies at all. To prevent the use of FB cookies, you should configure FB tracking exclusively on the server-side.
For example, let’s say you’re a home improvement brand. You used to buy third-party audience data about people who visit DIY blogs, then retarget them across platforms using cookies.
In a cookieless setup, this won’t work anymore. If someone visits your site without logging in or giving consent, you can’t retarget them one-to-one. That’s why platforms like GA4 or Facebook CAPI now rely on server-side setups
Three things changed the way tracking works:
Consumers started demanding more privacy and control. They don’t want to be tracked across the internet without knowing it.
Browsers and tech companies like Apple and Google responded by adding restrictions and phasing out third-party cookies.
Marketers now need new ways to measure performance and personalize content without relying on third-party data.
Cookieless means collecting user data without relying on cookies.
Third-party cookies are used to track users' activities across websites, so later the data is sent directly to platforms like Google Analytics or Meta.
This method is called ‘web tracking’.
Web tracking often results in lost data, as some events are not being registered due to browsers' privacy restrictions or ad blockers.
Cookieless tracking works without storing user data in cookies.
Instead of saving identifiers like user ID or session ID in the browser, this data is stored in a secure backend or passed through the cloud server directly.
Tools like server Google Tag Manager (sGTM) can help send events without relying on cookies, using alternatives like URL parameters or external ID systems.
This setup avoids cookie restrictions and improves tracking consistency.
Cookieless tracking works based on identifying and tracking users without relying on cookies, which are traditionally used to store user data on their device. Instead, it uses alternative methods like device fingerprints, server-side tracking, and other technologies to gather and process data.
With server-side tracking, the tracking code is executed on the server rather than on the user's browser. This means that the user's device does not need to store any tracking data, and the tracking is done entirely on the server side.
Server-side tracking can be implemented in several ways, including:
Stape has a full list of platforms that support server-side tracking.
To implement server-side tracking without cookies, it's essential to configure each tracking vendor purely on the server side. This approach ensures tighter control over the information each vendor sets and collects.
For instance, the standard configurations of platforms like Google Analytics 4, Facebook, TikTok, and many other analytics and marketing tools necessitate the use of both web and server-side tracking. Web pixels can freely gather data and set cookies in this setup, whereas server-side tracking steps in to assist web tracking when it faces challenges due to various tracking limitations.
With pure server-side tracking, you'll have a singular data stream that sends user and event data to the server-side container, which could be, for instance, webhooks from your CMS or CRM. Subsequently, within the server-based Google Tag Manager container, you determine what information gets relayed to your analytics and marketing platforms.
Cookieless tracking can look different depending on your setup, but the core principles stay the same.
Here’s what most cookieless configurations include:
Skip cookies completely
Don’t rely on browser cookies to store user or session data.
Instead, use a backend store like Stape Store. For cookieless GA4 tracking, this means saving values like client_id
, session_id
, and first_visit
directly in your backend.
Create your own identifiers
To link browser events with stored data, you need a consistent identifier.
This can be done with fingerprinting or Stape User ID.
Store click IDs in an external database
Capture important click IDs like fbclid
from the URL on the landing page, and save them in your backend. This helps platforms like Meta match conversions to the right ad clicks, even without cookies.
Some platforms use hashed identifiers when cookies are blocked. This usually means combining IP, user agent, and URL to generate a unique ID that’s stored server-side.
This method can work, but it’s a one-way system. You can’t enrich or update user profiles later. Tools like server GTM and Stape Store give you more flexibility to manage identifiers, connect events, and keep user data compliant without being locked into hashing.
Often, yes.
In the EU, GDPR rules require user consent if you collect personal data, even if you don’t use cookies. That includes IP addresses, emails, and any identifiers that can be linked to a person.
Some countries like Denmark, Belgium, and Germany ban all cookies (even functional ones) without explicit consent. These stricter rules are expected to expand across the EU under the upcoming ePrivacy Regulation.
In the US, rules vary by state. Some, like California’s CCPA, focus more on transparency and giving users the option to opt out.
Always check with your legal team to understand what applies in your region and how your setup handles user data.
As cookies become less reliable, marketers need a new approach to collect data and measure results.
Here’s what to focus on:
Not exactly, but using them without proper consent is.Laws like GDPR require websites to obtain explicit permission before using most cookies, especially those used for advertising or cross-site tracking.
Not completely.
It removes data saved in the user’s browser, but tracking can still happen in other ways, like using data sent through the website’s server.
That’s why many marketers now use both browser and server tracking to keep their data accurate and complete.
So there it is – an overview of how cookieless tracking works and what it can do for your marketing campaign.
