Works with your existing tools

Three steps. Five minutes.

Install the script, add hidden fields to your forms, and attribution data flows into your CRM.

Install the script

One line of code in your site header. Or install the WordPress plugin.

Add hidden fields

Add hidden fields to your form builder. SourceTag populates them with attribution data when a visitor submits.

Data flows to your CRM

Channel, source, campaign, click IDs, landing page, visit count. All in your form submissions and CRM records.

Configurable channel rules

Other tools give you hardcoded channels. SourceTag lets you reorder priorities, disable channels you don't need, extend defaults with your own values, or add entirely custom channels.

11 default channels based on GA4's standard groupings. Each one shows what data goes into the detail fields. Change it if you need to.

First contact and last contact

Know what brought them in AND what converted them. SourceTag captures both the first marketing touchpoint and the most recent one. Both are included in every form submission.

4 detail fields per contact point, context-dependent per channel. Defaults are set for you, but you can change them.

Why you need both

More than just UTM parameters. Channel, source, campaign, click IDs, landing page, visit count, device type, and more.

Attribution
