UTM
UTM parameters are tags appended to a URL that record where a visitor came from: the source, the medium, the campaign, and optionally the content and the term. They are how external traffic becomes attributable rather than merely countable.
What is UTM?
UTM parameters are tags appended to a URL that record where a visitor came from: the source, the medium, the campaign, and optionally the content and the term. They are how external traffic becomes attributable rather than merely countable.
Without them, a visit arriving from a newsletter, a social post, and a display banner all appear as the same referral. With them, each is distinguishable — which is the difference between knowing traffic exists and knowing which effort produced it.
The five tags and what they answer
Source identifies where the traffic came from, such as a newsletter or a social platform. Medium describes the kind of channel, such as email, paid, or social. Campaign names the specific effort, which is what lets you compare initiatives. Content distinguishes variants within a campaign, useful for testing creative. And term records the keyword where paid search is involved.
Together they answer the question that budget decisions depend on: which activities actually deliver, and which merely look busy. Since external traffic is often the most expensive traffic a brand drives, being unable to attribute it is an avoidable waste.
Using them without creating a mess
Three disciplines. Agree a naming convention before anyone tags anything, because inconsistent capitalisation and wording splits the same campaign into several entries that must then be merged by hand. Keep the tagging consistent between the links you build and the analytics you use to read them. And tag every off-marketplace link you create — newsletters, social posts, influencer links, and any destination that sends traffic to your listings.
The tagging parameters themselves do not affect how the destination page behaves; they simply travel with the click and are recorded by the analytics platform. That makes them cheap to add and easy to overlook — which is exactly how external traffic ends up unattributed.
In practice
A brand defines a naming convention for source, medium, and campaign, and applies it to every link it publishes — newsletter, social, influencer, and QR codes. After a quarter it can rank its external activities by contribution and shift budget towards the two channels that actually convert.
How Harpy Media helps
Attribution is part of our growth work: external links tagged consistently, channels compared on contribution, and budget moved towards what the data shows is working.
UTM FAQ
What are UTM parameters?
Tags appended to a URL recording where a visitor came from — source, medium, campaign, and optionally content and term — so analytics platforms can attribute the visit.
Do they change the page?
No. They travel with the click and are read by the analytics tool. The destination page behaves normally, which is why adding them is cheap and skipping them is easy.
What matters most?
Consistency. Agree a naming convention before tagging anything, or the same campaign appears under several names and the reporting becomes too messy to act on.
