userscript: Drop the UTM params from a URL when the page loads

utmstrip.user.js

// ==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); 
  }
  
}

@paulirish is this codeblock still valid with the new ga.js

@timelf123: is that line of code a replacement for the script or a add-on to the GA code to better work with this script?

Thanks!

If you load example website https://mashable.com/ you will still see /article/bla-bla-bla/?utm_campaign=hp-r-2&utm_source=internal&utm_medium=onsite being loaded after each link when you hover article.

Perhaps we can strip / rewrite source code on page load? Any idears?

If we have a userscript manager installed (such as Tampermonkey), it's quicker to add your script by clicking the Raw button.

As we all know how Google abuses privacy by Search url tracking, let's put an end to that once n for all:

// ==UserScript==
// @name         Cleanup Google Search URLs
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description Put an end to Google Search Tracking
// @author       VS
// @match        http*://*.google.com/search*
// @include      /^https?\:\/\/.*.google\..*\/.*$/
// @icon         https://www.google.com/s2/favicons?sz=64&domain=google.com
// @grant        none
// ==/UserScript==
(function(){
    'use strict';
    let url = window.location.origin;
    let currUrl = window.location.href;
    let cleanUrl = currUrl.split('&')[0].split('#')[0];
    // let cleanUrl = currUrl.replace(/\(pp_w\d+_h\d+\)/gi, '');
    window.history.replaceState({},'', cleanUrl);
    // window.history.pushState({page:cleanUrl}, cleanUrl, cleanUrl);
})();

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).
