Create and sync ad conversion events with your Reddit Ads account
Last updated: November 10, 2026
Available with any of the following subscriptions, except where noted:
After you connect your Reddit Ads account, create ad conversion events to send conversion data from your HubSpot CRM to Reddit. When a key event occurs in your CRM, such as a contact submitting a form, HubSpot automatically sends a conversion signal to Reddit.
Reddit uses these signals to optimize ad delivery for outcomes like sign ups and purchases instead of only clicks and views.
Please note: if you're a Super Admin, you can opt your account into the Reddit Ads Integration beta.
Use case: optimize Reddit ad delivery for form submissions
Sprocket Supply Co., an ecommerce company selling sustainable office supplies runs Reddit ad campaigns that target communities focused on workplace sustainability and small business ownership. Their campaign reports show strong click and impressions counts. The marketing team wants to know which of those clicks become qualified leads.
A marketer at Sprocket Supply Co. creates a Reddit ad conversion event that sends a signal to Reddit when a contact submits a form. They set a higher value for this event than for a page view. Each time a contact reaches that stage, HubSpot automatically sends the conversion to Reddit. The team monitors the number of synced events from the Events tab on the Ads page.
Reddit can then use this data to prioritize people who resemble Sprocket Supply Co.'s form submitter. The team stops relying only on clicks and impressions, and bases campaign optimization on lead quality.
