You Ask, I Answer: Why Email Clicks Don’t Match GA4

In today's episode, something about AI for once. Erica asks, uh, we track link performance in our newsletter and see discrepancies between the number of clicks reported for each item on the email platform versus the page views in Google Analytics for GA4 page views are always lower. Is there a reason for this? Yes, there's several reasons for this. Um, there's a lot of reasons why this will be the case.

Number one, um, depending on your audience, particularly if you are serving a corporate audience, there are firewalls thing and services like Barracuda, for example, that read every email sent to a corporate email address and click on every link that move. Why? Why do they do this? Because they are looking for malware. They are looking for malware, they're looking for hijackware, ransomware, all this stuff.

Anything that could be a hostile link that could damage the person's computer at work, these tools are looking for because they're gonna click on everything. Um, so automatically you're gonna have more clicks on your emails than you will see as page views because they're not gonna fully load the page. They're looking just for the payload. They're gonna look at HTTP header because it's too expensive to load the entire page. So that's one aspect.

Second aspect is Google Analytics for, depending on how you have it set up. Most people have it set up in the standard configuration where you just install your tracking code on your web page in tag manager or the analytics tracking script, and you consider it done. You are probably missing about 40% of your traffic that way because of things like privacy protection, ad blockers, uh, script blockers, etc. All those things block, uh don't run. They just do not run the Google Analytics for tracking script.

So you are automatically gonna have less clicks just from that alone. And that's not email, that's anything. Anywhere that you're sending traffic via to your website, if someone has certain types of technologies like the iPhone, um, stuff's gonna go missing. And it could be a lot of stuff. When we did this recently for ourselves, we found that about 40% of our clicks to conversions were gone.

Um because the tracking goes were not loading. That's a big number. So that's gonna impact things. Another thing is deduplication. Uh if your email provider, how it handles duplicate clicks, does it give you a unique click number versus a total click number?

Um how does Google handle that differently? Because Google handles users differently based on the tracking. This presents issues with particularly users switching from device to device. So if I'm not signed in on my Google account, or maybe I am, or maybe I've got multiple Google accounts, and I read your email on my phone, and then I go to my desktop computer, and maybe I'm signed into a different account there, and I read your email again, and I click on something in each place on my phone and on my desktop. Guess what?

Because they're different devices, because the user really is a device most of the time in analytics software, you're gonna get different numbers again. So you're you're running you're gonna run into a lot of accuracy issues. All digital marketing analytics are things that you should treat as directional, the directional. Um, because of the level of inaccuracy from system to system, if you don't have if you try to treat them as absolute, you try to make everything one to one-to-one, you will be forever frustrated. You will be a very unhappy person for a very long time because there is no way to do that.

These tools are not direct, these tools are not precision tools, they are directional tools at best. And so don't try to make a perfect match. You're gonna be unhappy. Instead, look at the trends in your data. Are things on average going up?

On uh is your open rate going up on average, even acknowledging the crazy things like Apple, for example, Apple Mail pre-opening emails the moment you send it. I'm sure if you've been tracking your open rates, you've noticed anybody who's using Apple Mail, regardless of the kind of account they have, it goes through Apple's uh mail private proxy service, which means that Apple opens those emails the moment they're sent. Whether Anaheeman isn't gonna read it, and you don't know when the user opens the email because it's been pre-opened and preloaded for the user in their Apple Mail client. So even that is gonna throw and skew some things on you. And this isn't just email, by the way, this is everything.

This is social media, this is search, this is you name it. There's so much distortion now in digital marketing data. The best thing you can do is rely on direction to say, like, okay, this is a directional finding. Um, and the closer you are to the bottom and the funnel, the more accurate your data is gonna get. Because at the end of the day, either there's money in your bank account or not, everything else is directional.

What matters is that end outcome. And if you're not measuring that, there are much bigger problems to worry around. Anyway, thanks for the question. Especially the fact that it's a non-AI question. Thanks for the question.
