// ==UserScript==
// @name UTM param stripper
// @author Paul Irish
// @namespace http://github.com/paulirish
// @version 1.2
// @description Drop the UTM params from a URL when the page loads.
// @extra Cuz you know they're all ugly n shit.
// @include http*://*
// ==/UserScript==
// Update:
// In chrome, it's better to just install the UTM stripper chrome extension:
// https://chrome.google.com/webstore/detail/google-analytics-paramete/jbgedkkfkohoehhkknnmlodlobbhafge
// It is great and open source: github.com/mihaip/utm-stripper
// You can also install this greasemonkey script if you really want.
// download this script. go to about:extensions. Turn on developer mode and drag and drop
// this file onto the window. it'll install it. hopefully.
// lastly, if your site / marketing funnel uses these tracking tokens. you can clean up your users URLs
// look at the comments below on correct installation to integrate with __gaq.push
if (/utm_/.test(location.search) && window.history.replaceState){
// thx @cowboy for the revised hash param magic.
var oldUrl = location.href;
var newUrl = oldUrl.replace(/\?([^#]*)/, function(_, search) {
search = search.split('&').map(function(v) {
return !/^utm_/.test(v) && v;
}).filter(Boolean).join('&'); // omg filter(Boolean) so dope.
return search ? '?' + search : '';
});
if ( newUrl != oldUrl ) {
window.history.replaceState({},'', newUrl);
}

The script does not work with links pasted by the Augmented Steam browser extension. Links like https://steamdb.info/app/.../?utm_source=Steam&utm_medium=Steam&utm_campaign=SteamDB%20Extension and https://pcgamingwiki.com/api/appid.php?appid=...&utm_source=Steam&utm_medium=Steam&utm_campaign=SteamDB%20Extension remain unchanged. Mozilla Firefox 111.0b5 (64-bit), Tampermonkey 4.18.1 (January 17, 2023).
