Frequently Asked Questions
What are UTM parameters?
UTM parameters are tags added to the end of a URL that tell analytics tools where your traffic came from. They identify the source, medium, and campaign behind each click.
Which UTM parameters are required?
utm_source, utm_medium, and utm_campaign are the core parameters most analytics setups rely on. utm_term and utm_content are optional and used for paid keywords and A/B testing.
Are values automatically encoded?
Yes. The builder URL-encodes each parameter value, so spaces and special characters are handled correctly and your links stay valid.
Does this tool store my URLs?
No. The campaign URL is assembled in your browser, so nothing you enter is uploaded or saved on a server.
