Here's what this means for you. You discover how a self-hosted URL shortener solves attribution problems when email marketing software sends non-standard UTM codes. You'll also learn these concepts: how Google Analytics 3 lets you customize default channel groupings while Google Analytics 4 hard-codes them, why non-compliant UTM codes break GA4 attribution tools, and how a URL shortener strips and replaces bad tracking codes the moment someone clicks.

Oh, well, it depends. It depends on your email marketing platform. One of the challenges is that not all email marketing platforms are the same. Not all of them have the same commitment to analytics excellence. And so a lot of the time I find myself uh hard coding those links using a URL shortener of some kind. So I have a uh tool that's an open source tool called URLs. It's uh y-o-r-l-s.org. And it's a self-hosted URL shortener. If you've ever used, say, Bitly or any other uh major URL shortening uh software, it's the exact same thing, but it's yours. It's uh it runs on your domain, and you can make it you can buy your own domain uh shortening domain. So like I use cs pen.com for uh my my short links. Um there is a module for Google Analytics. So Google Analytics integration allows it to send uh tracking data and append all the UTM codes exactly the way that I want them to be set. That makes shortening URLs a lot easier. And then I use that software for social media, uh, for private social media, for emails, uh, you name it. And I do that because in Google Analytics 3, there's a lot of flexibility when it comes to uh how you can define you know sources and mediums and default channel groupings. So anytime you're in the application where uh you're looking at default channel groupings, like an attribution analysis, out of the box, it's not usually right. Uh that's just the nature of the beast. But you can customize it. You can say, okay, any traffic from Facebook.com should always be counted as social media, right? Um you can't do that in Google Analytics 4. Google Analytics 4, all of the channel definitions that you see in the application are hard-coded in by Google, and we don't get a choice. And so if we have email marketing software or marketing automation software that is sending non-standard UTM codes, meaning that uh it's doing things like capitalizing them, it's switching them back and forth. Whatever the case is, we don't want our software sending that data to Google Analytics 4, because then a major channel, right? Social media or uh email is gonna get misattributed. It's gonna get put in the wrong bucket or no bucket at all. And then the built-in attribution tools in Google Analytics 4 simply will not work. So, to answer your question, it depends on your platform software. If they are adhering to Google's best practices and they are showing up with the correct UTM tracking codes for the source in the medium that you're working for, then use the built-in ones. On the other hand, if they are non-standard or non-compliant, then you're better off making the UTM tracking codes yourself in a URL shortener and putting the shortened URLs in the email. Because even then, if the software sends the wrong UTM codes, the moment that the visitor clicks on that link and goes to your URL shortener, your URL shortener will expand it and it will have the correct UTM codes. The other ones, the old ones will get dropped off and they'll have the correct new ones on there, and that will give you much better data. So it depends. You'll have to do some testing, right? You'll have to do some testing to figure out is this something that is correct or is this something that is non compliant? I strongly recommend that you check out the UTM tracking uh defaults for default channel groupings for both Google Analytics 3 and Google Analytics 4. You can find the documentation right on Google's website and make sure that you compare it with what your email software is sending. Great question. Thanks for asking.
