How to attribute LinkedIn Ads in HubSpot

If you cannot tie LinkedIn Ads spend to pipeline and Closed Won in HubSpot, you cannot scale confidently. HubSpot is where marketing and sales collaborate and revenue is measured.

When you attribute LinkedIn Ads in HubSpot, you can connect every Contact and Deal back to the original campaign and creative, compare ROAS by campaign, and prove what creates customers.

In this article, we will show how to use Attry to attribute LinkedIn Ads in HubSpot and which reports to build for a complete picture of performance.

What is Attry?

Attry is a lightweight script you add to your site. It detects where a visitor came from, normalizes it into channels like Paid Social, Paid Search, Organic Search, and stores the data in a cookie while the visitor browses.

On form submit, Attry writes the attribution into hidden fields so it travels with the Contact into HubSpot. It also records the first landing page and landing page group. If your HubSpot forms are embedded in cross-origin iframes, Attry loads a HubSpot specific adapter that patches hbspt.forms.create and injects attribution via onFormReady. The adapter is served from /api/integrations/hubspot/adapter and the source is inlib/attribution/hubspot-adapter.js.

4 steps to attribute LinkedIn Ads in HubSpot

Attributing LinkedIn Ads in HubSpot is simple with Attry. Follow these steps:

1) Add UTM parameters to your LinkedIn Ads

Tag your final URLs consistently so each visit includes a clean source pattern.

https://yourcompany.com/free-demo?utm_medium=paidsocial&utm_source=linkedin&utm_campaign=brand-us-q3&utm_content=creative-a

utm_medium = paidsocial
utm_source = linkedin
utm_campaign = campaign name
utm_content = creative

2) Add hidden fields to your HubSpot forms

Add hidden fields so Attry can write attribution on submit.

Channel
Channel Drilldown 1
Channel Drilldown 2
Channel Drilldown 3
Channel Drilldown 4
Landing Page
Landing Page Group

3) Install Attry on your site

Place the Attry snippet in the <head> so UTMs and click ids are captured before forms load.

4) Attry writes LinkedIn Ads data into the hidden fields

On submit, Attry injects the full attribution:

Channel = Paid Social
Channel Drilldown 1 = LinkedIn
Channel Drilldown 2 = Brand US Q3
Channel Drilldown 3 = Creative A
Channel Drilldown 4 = Creative A
Landing Page = /free-demo
Landing Page Group = free-demo

5) Use the data inside HubSpot

Once attribution is saved on each Contact, you can:

Show attribution on Contacts and Deals so sales has context for every inquiry.
Build dashboards that group Deals and revenue by campaign and creative.
Compare CPL, CPP, and ROAS by campaign to reallocate budget.

Why Attry beats raw UTM capture

All traffic

Attry captures attribution for every lead, not just LinkedIn Ads, so you can see the full picture.

Memory

Attry stores attribution in a cookie so the original source survives browsing.

Normalization

Attry cleans inconsistent UTMs so your reports stay tidy and comparable.

Landing pages

See which first pages and sections turn visitors into customers.

Iframe support

If your HubSpot forms are inside cross-origin iframes, Attry uses a HubSpot adapter to safely inject attribution inside the iframe.
