For marketing teams aiming to maximize ROI, understanding the source of leads and source of customers is non-negotiable. Yet, tracking affiliate-driven conversions often feels like chasing shadows—especially when using tools like WPForms.
In this guide, you’ll discover how to capture UTM parameters seamlessly, leverage hidden fields, and turn raw data into actionable insights—all while ensuring your CRM (like Salesforce) becomes a goldmine for growth decisions.

Why Affiliate Tracking Matters
Affiliate programs can drive significant traffic, but without precise UTM parameter tracking, you’re left guessing which partners deliver real value. Did a blogger or YouTuber drive that spike in sign-ups? Which campaign converted high-value customers?
By embedding UTM tags and using hidden fields in forms, you’ll not only track affiliate performance but also compare it against channels like Paid Search or YouTube campaigns. Let’s break it down.
4 Steps to Capture Affiliate Data in WPForms
1. Add UTM Parameters to Affiliate Links
Start by tagging affiliate links with UTM codes. For example: attributer.io/integrations/wpforms?utm_medium=affiliates&utm_source=bloggers&utm_campaign=john-smith
- Best Practices:
utm_medium: Label the channel (e.g., Affiliates).utm_source: Specify the affiliate type (e.g., Bloggers, YouTubers).utm_campaign: Name the affiliate (e.g., John-Smith).
Tools like Rewardful automate UTM tagging, while free builders create custom templates.

2. Embed Hidden Fields in Your Forms
WPForms allows you to add hidden fields to silently capture UTM parameters and other critical data. Include these fields:
- Channel (e.g., Affiliates)
- Channel Drilldown 1 (e.g., Bloggers)
- Channel Drilldown 2 (e.g., John Smith)
- Landing PageURL

This setup ensures every form submission carries a detailed lead source fingerprint.
3. Automate Data Capture with Attributer
When a visitor clicks a UTM-tagged link, Attributer stores their journey in the browser—even if they leave and return later. Upon form submission, it auto-fills hidden fields with:
- UTM parameters
- Initial landing page
- Campaign details
4. Analyze Data in Your CRM or Spreadsheet

Once WPForms captures the data, push it to Salesforce, HubSpot, or export via CSV. Use this intel to:
- Spot top-performing affiliates (e.g., John Smith drives 30% of conversions).
- Compare channels (e.g., Affiliates vs. YouTube ads).
- Calculate ROI by tying leads to revenue.
