How to Use UTM Parameters for Website Analytics With Fathom

UTM Parameters can help you identify where and how traffic made it to your site.

I’ve spent a fair amount of time working with Google Analytics, Ads, and other privacy-invading features. Which lead me to find Fathom Analytics, an analytics tool that doesn’t harvest and sell user data. We can tell what routes someone has visited on our site, the browser, and if they used a phone or desktop.

Unfortunately, this doesn’t tell us where our visitors are coming from.

Traffic without an origin isn’t super helpful

While it can help determine what browser support you should prioritize, you’ll miss out on knowing if:

  • Did they click a link you shared on Twitter?
  • That comment you left with a link to an article is getting some attention
  • Your newsletter recommended articles format is working
  • An A/B test for sharing content is successful

UTM Parameters can help with this and more without much work or setup.

Let’s look at how we’d set up UTM Parameters for this article.


We want to know the origin of our traffic.

Depending on where we shared the link to this, we’d put the platform’s name here like utm_source=twitter.


The campaign is specific to what you want to classify your links as.

For me, I’m writing this as part of Ship 30 for 30, so I tagged it with utm_campaign=ship-30-for-30


The medium is a marketing term for identifying if the traffic was from a paid campaign.

I don’t run ads, or campaigns for traffic, so I could put utm_medium=organic here.


This field is optional and can be used to separate links to content from the same campaign and source. Say you tweet twice a day, and you want to know which tweet the traffic came from; you could put the date and time like utm_content=04-04-2022-2000

Altogether, this would give us this beast of a link:

Gathering data for analytics is what UTM Parameters excel at, after putting in the work to set them up before you share a link.

Hopefully, you can see the power that UTM Parameters can grant you, but with that power comes the responsibility for respecting our users’ privacy and not harvesting to sell-off.
