Retargeting Analysis Template: ## Is Your Retargeting Cannibalizing Your Sales?
Read the full article below for detailed insights and actionable strategies.
Is Your Retargeting Cannibalizing Your Sales?
Retargeting seems like a no-brainer. You bring back interested customers and close the sale. But here’s the uncomfortable truth: a huge portion of your retargeting budget is likely wasted on customers who would have converted anyway. Standard attribution models, especially the last-click model used by ad platforms, are designed to make retargeting look incredibly effective. They give 100% of the credit to the final touchpoint, ignoring the fact that the customer was already deep in your funnel. You're paying to re-acquire customers you already won.
Causality Engine exposes this inefficiency. We use Bayesian causal inference to determine the incremental lift of your retargeting campaigns. Our platform analyzes your customer journeys to understand the probability of conversion with and without each marketing touchpoint. This allows you to see what percentage of your retargeting conversions are truly new sales and what percentage is just cannibalization of organic or direct traffic. This template provides a framework for conducting this analysis.
The Retargeting Analysis Template
This template is designed to be used with the insights from a Causality Engine analysis. It helps you move beyond the misleading metrics of your ad platforms and understand the true financial impact of your retargeting efforts.
| Metric | Description | Example Calculation |
|---|---|---|
| Reported ROAS (e.g., Facebook Ads) | The Return on Ad Spend as reported by the ad platform. | 12.0x |
| Incremental Lift (via Causality Engine) | The percentage of retargeting conversions that would NOT have happened otherwise. | 30% |
| Causally-Adjusted ROAS | Reported ROAS * Incremental Lift | 12.0x * 0.30 = 3.6x |
| Cost Per Incremental Acquisition (CPIA) | Total Campaign Cost / (Total Conversions * Incremental Lift) | €2,000 / (200 * 0.30) = €33.33 |
| Cannibalization Cost | Total Campaign Cost * (1 - Incremental Lift) | €2,000 * (1 - 0.30) = €1,400 |
How to Measure True Retargeting Impact
Ensure Your Pixel is Firing: Double-check that your Facebook/TikTok/Google pixel is correctly installed on your Shopify store and tracking purchase events.
Run a Causality Engine Analysis: Our platform will analyze your historical data to build a causal model of your marketing performance, establishing a baseline.
Isolate Your Retargeting Campaigns: In the Causality Engine dashboard, filter your results to focus specifically on your retargeting campaigns.
Analyze the Incremental Lift: Our Causality Chain Visualization will show you the probabilistic impact of your retargeting ads and calculate their true incremental value.
Refine Your Budget: Use the insights to adjust your retargeting spend. You might reduce your audience size, cap frequency, or reallocate the budget to more effective, top-of-funnel activities.
"We were spending €20k/month on retargeting and thought it was our best-performing channel. Causality Engine showed us that 70% of those sales would have happened anyway. We cut our retargeting budget in half and reinvested in influencer marketing, leading to a 25% increase in new customer growth." - Head of E-commerce, a 25M EUR Shopify Beauty Brand
Stop paying to get in front of customers who are already on their way to your checkout. It's time to measure the true, incremental impact of your retargeting.
