UTM Link Builder
Build campaign links with clean UTM parameters.
Runs entirely in your browser. Nothing is sent or stored.
Good to know
UTM parameters tell your analytics where a visit came from. Source, medium and campaign are required for clean reports, term and content are optional.
Stick to one spelling: otherwise newsletter and Newsletter show up as two sources in your reports. The lowercase option helps with that.
You can build short links with a QR code and their own statistics with Formspring Links.

At least utm_source, utm_medium and utm_campaign.
