Free UTM Builder for GA4 Campaign Tracking
A UTM builder turns a normal landing-page URL into a campaign URL that analytics tools can classify by source, medium, campaign, term and content. Use consistent lowercase naming so your reports do not split one campaign into several rows.
How this free tool works
Create clean UTM-tagged campaign URLs for GA4, Google Ads, Meta, email and social campaigns. Free, private and no signup required. The result is designed to be transparent: you can see the inputs, the formula and the assumptions instead of receiving a black-box score.
Final URL = landing-page URL + utm_source + utm_medium + utm_campaign + optional utm_term and utm_content.
Best for
- Marketers tagging paid, social, email and partner campaigns
- Teams that need consistent GA4 campaign naming
- Founders who want a fast, no-login link builder
Frequently asked questions
What is a UTM builder?+
A UTM builder adds campaign parameters to a URL so analytics platforms can identify where a visit came from and which campaign generated it.
Should UTM parameters be lowercase?+
Yes. GA4 treats values such as Facebook and facebook as different values. Lowercase naming prevents fragmented reports.
Does this tool store my campaign links?+
No. The link is generated in your browser. Do not place private data or customer information in UTM values.
