The Self-Hosted WordPress Stack: Unify Ad Audiences & Stop Wasting Spend

Are you wasting money showing retargeting ads to customers who have already converted? Inconsistent audience synchronization between Google and Facebook means you're annoying new leads and burning through your ad budget. When a user converts, they should be removed from your ad campaigns on ALL platforms, instantly.

This playbook details 'The Self-Hosted WordPress Stack'—the most cost-effective way to solve cross-platform audience exclusion. By leveraging your existing WordPress site, a powerful forms plugin, and a self-provisioned server-side container on Google Cloud, you create a central data hub. When a lead converts, a single event is fired to your server, which then instantly updates both your Google Ads and Facebook Custom Audiences. You gain full control over your first-party data, eliminate recurring software fees, and ensure your ad spend is only used to target potential customers.

Expected Outcomes

  • Eliminate wasted ad spend by instantly removing converted leads from retargeting campaigns.
  • Improve user experience by no longer showing irrelevant ads to new customers.
  • Achieve near real-time synchronization of your exclusion and custom audiences across platforms.
  • Gain full ownership and control of your first-party conversion data.
  • Dramatically reduce recurring software costs by using a self-hosted, low-cost stack.

Integration Logic

  • Fluent Forms Webhook Trigger

    This integration works by configuring a webhook within Fluent Forms. When a user submits a form on the WordPress site, Fluent Forms automatically sends an HTTP POST request containing the form submission data as a JSON payload to a specified URL. This URL is an HTTP-triggered endpoint on Google Cloud Platform, typically a Google Cloud Function. The Cloud Function receives this data, allowing you to execute custom code to process it—for example, storing the lead in a BigQuery database, sending a customized notification via Pub/Sub, or triggering another cloud service.
