The problem
Klaviyo tracks opens and clicks after someone subscribes, but can't tell you what brought them to your site in the first place. You see subscribers, not the campaigns that created them.
How to set it up
SourceTag captures attribution data on your website. When someone submits a form connected to Klaviyo, hidden fields carry the channel, source, campaign, and keyword into their subscriber profile.
Install SourceTag on your site
Add the script tag to your site header, or install the WordPress plugin.
Add hidden fields to your forms
Add hidden fields for attribution data to the forms connected to Klaviyo. The field names map to subscriber properties.
Check subscriber profiles
Submit a test form with UTM parameters. The attribution data shows up as properties on the subscriber profile in Klaviyo.
