Where it shows up
This is what you'll see in Google Analytics
Once your UTM link is clicked, GA4 shows the data in the Acquisition report — exactly like this.
| Source / Medium | Campaign | Sessions | Conv. rate |
|---|---|---|---|
| google / organic | (not set) | 3,241 | 2.1% |
| facebook / cpc | spring_sale_2026 | 1,847 | 4.8% |
| (direct) / (none) | (not set) | 1,103 | 1.9% |
| newsletter / email | monthly_digest | 612 | 6.2% |

FAQ
UTM questions,
answered.
Everything you need to know about UTM tracking, parameters, and Google Analytics — explained simply.
Ask a question?utm_source=facebook&utm_medium=cpc. Those tags tell Google Analytics where the traffic came from and which campaign it belongs to. Without them, all your traffic looks like "direct" or "social" with no detail.
utm_source. But the standard best practice is to always include utm_source, utm_medium, and utm_campaign together — otherwise your reports get noisy fast. utm_term and utm_content are optional refinements.
Facebook and facebook as two completely different sources, which splits your data into useless duplicates. Our builder warns you the moment you type a capital letter.
localStorage — it never reaches our servers. That means it's private and instant, but it stays on this device and browser only. Clear your browser data and the history clears too.
utm_term is mostly used for paid search keywords (e.g. free+utm+builder). utm_content is used to differentiate similar links — perfect for A/B testing two button copies or two ad creatives that point to the same page. Most non-paid campaigns only need source, medium, and campaign.
