About this tool

Appends correctly encoded UTM parameters to any URL for campaign tracking. The link is assembled in your browser.

What are UTM parameters?

Tags like utm_source and utm_medium added to a URL so analytics tools can attribute traffic to a campaign.

Are values encoded?

Yes, the builder uses the URL API so spaces and special characters are safely percent-encoded.
