Free UTM campaign builder

Build clean, consistent campaign tracking links in seconds. Values are normalized automatically, so your analytics never fragment.

What are UTM parameters?

Short tags added to the end of a URL that tell your analytics tool where a visitor came from. The three core tags are utm_source, utm_medium, and utm_campaign.

Does this work with Google Analytics 4?

Yes. GA4 reads utm_source, utm_medium, utm_campaign, utm_term, and utm_content automatically, in the Traffic acquisition reports.

Should UTM values be lowercase?

Yes. Analytics tools treat Newsletter and newsletter as different sources, which splits your reports. This builder lowercases values and replaces spaces with underscores for you.
