Spotlight Advertising Case Study
Store C
A before-and-after readout on the first Spotlight advertising window, using matched 65-day periods around the March 18, 2026 launch.
Spotlight launched with positive store-wide lift and a stronger brand-level signal.
Store revenue averaged $236 more per day after launch, for an estimated $15,362 lift over the matched 65-day post-launch window. Because 4/20 falls inside the after period, the report also shows a holiday-adjusted check: excluding Apr 20, store lift remains positive at +$8,732. The clearest commercial movement is inside the advertised brands: Advertised Brand A and Advertised Brand B together moved $40,291 above their matched baseline.

How the comparison works
The report compares the same number of days before and after the Spotlight launch. The post-launch window starts on March 18, 2026 and runs through the latest complete reporting day available for the store, May 21, 2026.

|---|---|---|---|
| Before Launch | Jan 12 – Mar 17, 2026 | 65 | $957,007 |
| After Launch | Mar 18 – May 21, 2026 | 65 | $972,369 |
| Estimated Lift | After Launch minus matched baseline | +1.6% | +$15,362 |

Before vs after brand revenue
Brand lift uses matched purchase-item revenue from the interaction commerce rollup for the same Store C launch windows.
| Brand | Before Launch | After Launch | Estimated Lift | Change |
|---|---|---|---|---|
| Advertised Brand A 1,768 purchases before; 2,326 after |
$60,090 | $83,951 | +$23,861 | +39.7% |
| Advertised Brand B 2,398 purchases before; 2,700 after |
$80,024 | $96,453 | +$16,430 | +20.5% |
| Combined advertised brands | $140,113 | $180,404 | +$40,291 | +28.8% |
The brand story does not depend on 4/20. Excluding Apr 20, Advertised Brand A is still up about $23,950 and Advertised Brand B is still up about $15,626 versus the matched baseline. Combined advertised-brand lift remains about $39,575 without the holiday.
What this means
- The store-wide read is positive. Store C averaged $236 more per day after launch, and still averaged $136 more per day when Apr 20 is excluded.
- The Spotlight brands are the strongest proof point. Advertised Brand A and Advertised Brand B combined were up $40.3K versus their own baseline, or about $39.6K excluding Apr 20.
- The channel is measurable. Spotlight produced 6,230 ad clicks, 4,458 purchase sessions, and $219.5K in attributed revenue context.
Important caveat: the brand lift and store lift should not be added together as one total. Store-wide lift measures the whole store. Brand lift isolates the advertised brands and can include mix shift from other products.
