Unify Ad Audiences with HubSpot to Eliminate Wasted Retargeting Spend

Are you wasting ad spend retargeting leads who have already converted? When a lead submits a form on your site, they're removed from your Google Ads audience, but they continue seeing the same ads on Facebook for days. This inconsistent synchronization drains your budget, creates a poor customer experience, and skews your campaign performance data.

This playbook outlines how to use HubSpot's built-in Ads Add-On as a single source of truth for your ad audiences. By syncing HubSpot contact lists—which update automatically based on customer actions—directly to Google and Facebook, you ensure converted leads are simultaneously removed from all retargeting campaigns. This low-effort, low-cost solution is perfect for businesses already using HubSpot who want to achieve seamless, cross-platform audience management.

Expected Outcomes

  • Dramatically reduce wasted ad spend by automatically excluding converted leads from retargeting campaigns.
  • Enhance the post-conversion customer experience by no longer showing them irrelevant acquisition ads.
  • Achieve more accurate campaign performance data by ensuring your ads are only shown to relevant prospects.
  • Save valuable time by automating cross-platform audience synchronization directly from your CRM.

Integration Logic

  • HubSpot Ads Add-On

    The HubSpot Ads Add-On works by creating a direct API connection between your HubSpot portal and your ad platform accounts (e.g., Google Ads, Facebook Ads). After you authorize access, HubSpot pulls in campaign, ad set, and ad-level data, including impressions, clicks, cost, and conversions. It uses the HubSpot tracking code on your website to associate ad clicks with website visitors. When a visitor converts (e.g., fills out a form), the ad interaction data is appended to their contact record in the CRM. This allows for closed-loop reporting, where you can attribute deals and revenue back to the specific ads and campaigns that influenced them.
