Sales lift reports are often treated as the ultimate proof of performance in retail media.
But they’re also one of the most misunderstood.
Many teams look at the headline number and stop there—without fully understanding what drove the result or whether it’s actually meaningful.
A sales lift report is only as valuable as how you analyze it.
Start With the Objective—Not the Result
Before diving into the data, revisit the original plan.
Ask:
- What was the campaign objective?
- Which KPIs were we trying to impact?
- How was success defined?
This context is critical.
Without aligning back to the objective, it’s impossible to interpret whether the results are actually good or bad.
Validate the Measurement Set
Next, confirm what products were included in the analysis.
- Which SKUs were measured?
- Are the hero SKUs accurate?
- Does the set reflect what was actually promoted in the campaign?
If something looks off:
Don’t hesitate to ask the retail media network to rerun the report.
An incorrect SKU set can completely distort the results.
Evaluate KPI Performance in Context
Once the foundation is validated, review the primary KPIs.
- Did performance meet or exceed expectations?
- How does it compare to:
- Previous campaigns
- Year-over-year trends
- Total-year performance
Retailers may offer benchmarks—but many still do not.
In most cases, your own historical data is the most reliable point of comparison.
Identify What Drove the Result
The next step is understanding why performance looked the way it did.
This requires looking beyond the headline KPI and analyzing supporting metrics, such as:
- Reach
- Frequency
- Add-to-cart rate
- New-to-brand customers
- Conversion rate
- Creative performance
- Audience performance
If a KPI was missed, one (or more) of these metrics will usually explain why.
Look for Signals, Not Just Numbers
For example:
If frequency is significantly higher than industry norms (e.g., 15x vs. ~6x), it may indicate overexposure and limited reach.
In this scenario:
- The campaign may not be reaching enough new shoppers
- Incremental growth becomes harder to achieve
- iROAS is likely to underperform
High exposure doesn’t always mean effective reach.
The Bottom Line
Sales lift reports should not be treated as a final answer—they’re a starting point.
The real value comes from understanding what drove the result and what to do next.
A strong analysis:
- Aligns results back to the objective
- Validates the underlying data
- Identifies the drivers of performance
- Leads to clear next steps
Teams that take this approach don’t just report on sales lift—they learn from it.
