UTM Link 101: Everything You Need to Know
A UTM link (Urchin Tracking Module) link is a web page URL with a few pieces of tracking code added to the end. These “tags” tell Google Analytics 4 (GA4) and similar analytics tool exactly where your visitors are coming from. Without them, your marketing data is “dark,” often showing up as generic Direct traffic.

You must build the UTM link before you share it. GA4 only reports data; it doesn't create the links for you.

The 3 Steps to Building, Using, and Reporting on a UTM Link
Understanding where the "Building" ends and the "Reporting" begins.
The Build (Outside GA4)
You must create your campaign URL before you launch your promotion. GA4 doesn't have a "Create Link" button.
The Distribution
Take your finished tracking link and paste it into your destination:
- Facebook/LinkedIn Ads
- Email CTA Buttons
- YouTube Descriptions
The Reporting (Inside GA4)
Only after a user clicks the link does GA4 "see" the parameters and sort them into your reports.
What are UTM Links and Why Do They Matter?
If you promote your registration or product page on Facebook, LinkedIn, and in an Email without adding UTM tags to the URL, GA4 might bucket all visits coming from these platforms all together. A UTM link breaks that down by adding “parameters.”
These parameters help GA4 actually tell you how many people came from Facebook vs LinkedIn, for example.
The Anatomy of a Tagged Link:

Source: The platform (e.g., Google, Facebook).
-
Medium: The channel (e.g., CPC, Email, Social).
-
Campaign: The specific promotion name.
Frequently Asked Questions
How do I create a UTM link?
You can create them manually by typing the codes yourself, but it’s risky. One typo or an extra space can break the tracking. Most professionals use a Campaign URL Builder to ensure the link is perfect every time.
Do I put UTMs on YouTube links?
Yes! To see if your YouTube traffic is coming from a video description, a pinned comment, or an end screen, you must use unique UTM links for each placement.
Do I need a separate shortener like Bitly for my UTM links?
While many marketers use external tools like Bitly, the most efficient way to manage your links is with a native, integrated shortener like ctrly.io that directly integrated with your GA4 utm builder tool.
The “Old” Way (Manual & Fragmented):
-
Generate a long UTM link in one tool.
-
Copy and paste it into a separate shortener.
-
Manage two different dashboards to see your data.
The CampaignTrackly Way (Automated & Unified): With our built-in ctrly.io shortener, the process is seamless. You generate your UTM parameters and shorten the link in a single click. This keeps your “Source/Medium” data perfectly intact without the “redirect data loss” that often happens with 3rd-party shorteners.
💡 Pro-Tip: Using a native shortener like ctrly.io ensures that your “Click” data in your dashboard matches your “Session” data in GA4. When you jump between too many tools, you lose accuracy.
How do I track goals from UTM links?
Once your links are tagged, GA4 automatically associates every conversion (purchase, lead, sign-up) with that specific Source and Medium. You can find this in Acquisition > Traffic Acquisition.
