bjornpagen / ga4-utm-parameters-event.js
Created January 31, 2023 03:20
A JavaScript code snippet for logging UTM parameters as a GA4 event, only including parameters that are set in the URL and omitting any parameters that are not set.
// Get the UTM parameters from the URL
var search = window.location.search;
var params = new URLSearchParams(search);
// Keep track of if an event has already been logged
var eventLogged = false;
// Loop through each UTM parameter
for (var [key, value] of params.entries()) {
// Check if the parameter is "utm_source", "utm_medium", "utm_campaign", "utm_term", or "utm_content"

bjornpagen / append-utm-params.js
Last active January 31, 2023 03:00
Append UTM parameters to specific domains in a webpage using JavaScript. The function loops through all the links on a page and checks if the link is part of the specified domains. If it is, the UTM parameters from the URL are added to the link.
function appendUTMParams(domains) {
// Get all the links on the page
var links = document.getElementsByTagName("a");
// Get the UTM parameters from the URL
var search = window.location.search;
var params = new URLSearchParams(search);
// Array of allowed UTM parameters
var allowedUTMs = ["utm_source", "utm_medium", "utm_campaign", "utm_term", "utm_content"];
