Overview
Marketers can see exactly where their leads are coming from. In addition to Document Referrer, Knock2 automatically captures all five standard UTM parameters — giving you full visibility into the campaigns driving traffic and conversions.
These data points are visible inside your Contacts tab and can be used for filtering, sorting, and routing leads to any of your connected outputs (Slack, HubSpot, Salesforce, etc.).
⚠️ Note: Document Referrer and UTM parameters are currently available for Contacts only. Support for Accounts is coming in a future update.
What's Included
Knock2 captures the following traffic source fields:
Parameter | Description |
Document Referrer | The original URL or page that referred the visitor to your website (e.g., a blog post, partner site, or landing page). |
UTM Source | Identifies where the traffic came from (e.g., Google, LinkedIn, newsletter). |
UTM Medium | Describes the marketing channel (e.g., CPC, email, social). |
UTM Campaign | Names the campaign that brought the visitor in (e.g., q4_product_launch). |
UTM Term | Tracks specific keywords or search terms. |
UTM Content | Differentiates versions of an ad or creative (e.g., video_ad_a vs banner_b). |
How It Works
When a visitor lands on your site with UTM parameters or a referring document, Knock2 automatically:
Captures the Document Referrer and all available UTM values from the URL
Saves them to the visitor's contact record inside the Contacts tab
Makes them available for filtering, sorting, and custom filter presets
Enables lead routing and campaign attribution based on your conditions

How to Enable Document Referrer in Your View
Document Referrer is not shown by default. To add it as a column in your Contacts tab:
Go to the Contacts tab
Click the three-dot menu in the top-right corner of the table
Select Columns
Toggle on Document Referrer
Once enabled, it will appear as a column in your table and be available for filtering.
