UTM Builder
Tag any link for campaign tracking. Casing and spacing cleaned as you type, so your analytics never split one channel into three.
Paste a tagged URL and the fields fill in automatically.
utm_source
GA4 channel vocabulary
utm_campaign
utm_content, optional
utm_term, optional
Values are lowercased and spaces become dashes automatically, so Spring Sale saves as spring-sale.
Your tracking URL
https://yoursite.com/spring-sale?utm_source=newsletter&utm_medium=email&utm_campaign=spring-launch
Save a source and medium combo to reuse it on your next campaign.
UTMs stop at the web. sniffurl carries this campaign context into your app, through the install, so every link ties back to a real conversion.
