UTM parameters are tags you add to a link so Google Analytics knows exactly which campaign, channel and ad brought each visitor.
| Parameter | What it tracks | Example |
|---|---|---|
utm_source | The site or platform sending traffic. Required. | google, facebook |
utm_medium | The channel type. GA4 uses it to group traffic into channels. Required. | cpc, email |
utm_campaign | The campaign or promotion name. Required. | spring_sale |
utm_term | The paid keyword that triggered the ad. | seo agency |
utm_content | Which ad, banner or link was clicked, for A/B tests. | video_ad |
UTM builder: common questions.
What is a UTM link?
A UTM link is a normal URL with tracking tags added to the end. When someone clicks it, Google Analytics records the source, medium and campaign, so you can see which marketing actually brings visits and sales.
Which UTM parameters are required?
Use at least utm_source, utm_medium and utm_campaign. Term, content and campaign ID are optional and help when you run several ads or keywords in one campaign.
Should UTM values be lowercase?
Yes. UTM values are case sensitive, so Facebook and facebook show up as two different sources. This tool lowercases values by default to keep reports clean.
Do UTM parameters affect SEO?
Not when used correctly. Never add UTM tags to internal links on your own site. They overwrite the original source of the session and can create duplicate URLs.
Why is my traffic showing as Unassigned in GA4?
Usually because utm_medium does not match a GA4 default channel rule. Values such as cpc, paid_social, email and social are recognised, while custom values often are not.
