Overview
Cookieless tracking is a modern attribution method that enables marketers to track user activity and conversions without relying on third-party browser cookies. It is designed to ensure accurate measurement while staying compliant with evolving privacy regulations like GDPR and browser restrictions.
Trackier provides a cookieless tracking solution that helps advertisers maintain performance visibility even in a privacy-first digital ecosystem.
What is Cookieless Tracking?
Cookieless tracking is a method of attribution where user actions (clicks, installs, conversions) are tracked without storing cookies in the browser. Instead, it uses alternatives like:
Server-to-server (S2S) postbacks
First-party identifiers (click IDs, session IDs)
Device and contextual signals
Secure server-side processing
This ensures tracking continues even when cookies are blocked or unavailable.
You need to make sure of the checklist below to ensure this setup works.
Setting up the campaign URL and make sure to pass Trackier click Id in the landing page URL
Add the Script mentioned below on all Landing pages.
Placing Conversion pixel on respective Thank you pages.
Step 1
Add your landing page URL and pass the trackier click id as suggested below and the utm_campaign parameter as suggested.
https://www.yourwebsite.com/?utm_campaign=trackier_{camp_id}&click_id={click_id}
Steps 2
Now you need to add the below script on all Landing pages, this script will make sure we get the session id or click id even when the browser or device doesn't support third-party cookies.
This is the script tag that can be placed in <head> Tag.
<script src="https://static-cdn.trackier.com/js/trackier-lp-v1.1.0.js"></script>
Step 3
Now you need to define on which page Pixel needs to be added and get that pixel from the platform, you need to make sure to get your Domain and Security Token from your Trackier panel inside the particular campaign.
This will go in <body> Tag
iFrame Pixel
// Trackier Integration Code for Thank You Page<script>
(function () {
function getCookieVal(name) {
var allCookies = document.cookie.split('; ');
var result = null;
allCookies.forEach(function (v) {
if (v.indexOf(name + '=') !== -1) {
result = v.split('=')[1];
return false;
}
})
return result;
}
var clickId = getCookieVal('click_id') || '';
var tr_utm_camp = getCookieVal('tr_utm_camp') || '';
if (/^trackier_/.test(tr_utm_camp)) {
var a=document.createElement("iframe");
a.setAttribute("src","UPDATE_THE_URL_HERE&txn_id=PLEASE_UPDATE_THE_TXN_ID_HERE&sale_amount=PLEASE_UPDATE_THE_SALE_AMOUNT_HERE¤cy=INR&click_id="+clickId); a.style.width="1";a.style.height="1";
document.body.appendChild(a)
