UTM campaign URL builder

1. Enter the full destination URL and a campaign name. Choose a source and medium for a single link.
2. For a batch, enter one source | medium pair per line. Content and term, if provided, apply to every generated link.
3. Generate, inspect and copy your URLs or download a campaign CSV. Keep the same naming convention across your team.

For an autumn_launch campaign, create newsletter | email and linkedin | organic_social links pointing to the same landing page. Both share utm_campaign=autumn_launch while source and medium distinguish the channels.

Source identifies where the visitor comes from; medium identifies the channel; campaign groups the initiative. Content can distinguish placements or creatives; term can label a keyword. This tool requires source, medium and campaign for consistent links.

Existing utm_source, utm_medium, utm_campaign, utm_content and utm_term parameters are replaced. Other parameters and the URL fragment are preserved. Empty content and term remove old values for those fields.

Values are URL-encoded, but their spelling and letter case are preserved. Use a shared convention. Never put personal information, passwords or private tokens in campaign URLs.

Use tagged links for external campaigns, not internal site navigation: internal tagging can make attribution harder to interpret. UTM parameters alone do not install analytics or guarantee attribution.

Limits: 4,096 characters in the destination URL, 30 links per batch and 5,000 characters per field. Only HTTP(S) destinations without embedded usernames or passwords are accepted. This tool does not visit or validate the destination page.
