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 all HubSpot form embed modes -- native forms, iframe embeds, and HubSpot's newer V4 Forms SDK. It automatically detects which mode your forms use and applies the right population strategy. No HubSpot plan upgrade, extra JavaScript snippets, or bridge code needed on your pages.
Install the Tracking Script
Add the AttributionHub tracking script to your website. It starts capturing attribution data (UTM parameters, referrers, landing pages) immediately.
Create HubSpot Contact Properties
Create custom contact properties in HubSpot (e.g. ah_lt_channel, ah_lt_source, ah_lt_campaign) and add them as hidden fields to your forms. AttributionHub populates them automatically -- no manual URL building or custom code required.
Verify Your Setup
Submit a test form and check the contact record in HubSpot to confirm the attribution properties are populated. For iframe embeds, you can also inspect the iframe src URL in DevTools to see the parameters.
Use Cases
SaaS Companies — Connect marketing spend to pipeline. When a lead requests a demo through your HubSpot form, the sales team instantly sees whether they came from Google Ads, an organic blog post, or a partner referral.
B2B Services — Track which campaigns generate the best leads, not just the most leads. Attribution data on each contact lets you calculate true cost-per-qualified-lead.
Agencies Managing Client HubSpot Portals — Give clients clear, contact-level proof that your campaigns work. Attribution data in HubSpot means reporting pulls directly from the CRM.
Multi-Channel Marketing Teams — Compare paid search, organic social, email campaigns, and content marketing side by side using real lead data, not just traffic metrics.

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. Native forms, iframe embeds, and HubSpot's newer V4 Forms SDK are all fully supported.
Does this work with HubSpot's new form editor (V4 Forms SDK)?
Yes. AttributionHub detects the V4 Forms SDK automatically and uses HubSpot's official API to populate attribution fields. This includes forms that load dynamically after the initial page render. No extra configuration needed.
Do I need to add any custom JavaScript code to my pages?
No. Unlike other attribution tools that require you to paste bridge scripts on every page with a HubSpot form, AttributionHub handles everything automatically. Just install the tracking script once and it detects and populates all HubSpot forms on your site.
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.
