HubSpot Forms Attribution Tracking
Finally see which marketing channels, campaigns, and keywords are actually filling your HubSpot pipeline. AttributionHub captures attribution data and writes it directly into HubSpot contact properties — automatically, on every form submission.
The Problem With HubSpot's Built-In Attribution
HubSpot has its own analytics, sure. But if you've ever tried to track exactly which Google Ads keyword led to a specific contact, or which LinkedIn campaign generated that high-value demo request, you know the frustration.
HubSpot's native reporting works at the aggregate level. It shows you traffic sources and conversion rates, but it doesn't attach granular marketing data to individual contact records. When your sales team picks up the phone, they don't know if that lead came from a $50/click branded search term or a $2 blog post.
AttributionHub fills this gap by capturing first-party attribution data at the visitor level and writing it directly into HubSpot contact properties. Every form submission arrives with its complete marketing context attached.
What Data Gets Captured
UTM Parameters
Source, medium, campaign, term, and content values — captured from URLs and stored as HubSpot contact properties.
Landing Page & Referrer
The exact page a visitor first landed on and the website that referred them, giving you complete entry context.
Channel Classification
Automatic categorization into Paid Search, Organic Social, Email, Direct, Referral, and more — consistent across all leads.
First Touch & Last Touch
Both the original source that brought the visitor to your site and the touchpoint that triggered the conversion.
How It Works
AttributionHub works with both HubSpot's native embedded forms and iframe-based embeds. No code changes on the HubSpot side are needed beyond creating a few custom properties.
Step 1: Create Custom Contact Properties
In HubSpot, go to Settings > Data Management > Properties. Create new contact properties for each attribution field. Set the Internal name to match AttributionHub's field names — this is what connects the two systems.
Step 2: Add the AttributionHub Script
Place the tracking snippet on your website, the same way you'd add any analytics script:
<script src="https://cdn.attributionhub.com/attribution.js?id=YOUR_ID" async defer></script>
It runs in the background, captures visitor context on every page view, and stores attribution data until a form is submitted.
Step 3: Add Hidden Fields to Your HubSpot Forms
In the HubSpot form editor, add your custom properties as hidden fields. AttributionHub detects HubSpot forms automatically — whether they're embedded natively or loaded via iframe — and populates the hidden fields before submission.
| Contact Property | Internal Name | Example Value |
|---|---|---|
| Channel | ah_channel | Paid Search |
| Source | utm_source | |
| Medium | utm_medium | cpc |
| Campaign | utm_campaign | brand-awareness-q1 |
| Keyword | utm_term | hubspot crm attribution |
| Landing Page | ah_landing_page | /features |
| Referrer | ah_referrer | linkedin.com |
Step 4: Test Your Setup
Visit your site with UTM parameters, navigate to your form, and submit a test entry:
https://yoursite.com/demo?utm_source=google&utm_medium=cpc&utm_campaign=brand-awareness-q1
Check the contact record in HubSpot — your custom properties should be populated with the correct attribution values.

Frequently Asked Questions
Does this replace HubSpot's built-in analytics?
No, it complements them. HubSpot's analytics give you aggregate traffic and conversion data. AttributionHub adds granular, contact-level attribution that travels with the lead through your sales pipeline.
Will this work if my HubSpot forms are embedded via iframe?
Yes. AttributionHub automatically detects iframe-embedded HubSpot forms and injects attribution data via URL parameters. Both native and iframe modes are fully supported.
Can I build HubSpot reports using attribution data?
Absolutely. Since attribution values are stored as standard contact properties, you can use them in any HubSpot report, list, or workflow — filter deals by channel, segment contacts by campaign, or trigger automations based on source.
How does this affect page load speed?
The AttributionHub script is under 10 KB and loads asynchronously. It has zero impact on Core Web Vitals or perceived page speed.
