HubSpot's Ads tool uses a last-touch attribution model to calculate ad conversions. When we detect a contact submission that includes our ad tracking parameters we pull the campaign and specific ad ID the contact interacted with immediately prior to their submission and increment the campaign's Lead or Customer data accordingly.
In order to track conversions using the HubSpot Ads Add-on:
- The HubSpot tracking code must be installed on your landing page. HubSpot landing pages include the tracking code by default; if you're using an external landing page, check out this article for instructions to install the tracking code.
- You must use a HubSpot Form, Collected Form, Lead Flow, or the HubSpot Forms API to capture submissions on your landing page.
- For LinkedIn Ads only: the ad campaign must be created in the HubSpot Ads tool. If the campaign is built in LinkedIn, we will not be able to track conversions within the HubSpot Ads Add-on.
