Retail promotion performance: sales uplift is not the verdict

Review retail and CPG promotions using a credible baseline, funding, costs, demand shifts and execution. Decide what to repeat, change or stop.

Skip to main content

A promoted item can sell more while the overall promotion creates less value than expected.

The useful question is not only whether sales increased. It is what changed compared with a credible alternative, who gained the benefit and what it took to deliver it.

Retailers and CPG businesses can reasonably assess the same event differently. Their costs, funding arrangements and commercial objectives differ. Agree the perspective before comparing the results.

For a manufacturer-funded event, use the CPG trade promotion evaluation guide to organize funding, claims, data gaps and review assumptions.

Six checks for the next promotion review

1. Objective

Was the event intended to recruit shoppers, increase category contribution, support a launch, clear stock or defend a value position?

2. Baseline

Establish what performance might have been without the event, using an appropriate comparison.

3. Funding and costs

Distinguish agreed funding from claims still awaiting confirmation.

4. Demand shifts

Examine plausible cannibalization within the category, complementary purchases and changes before or after the event.

5. Supply and execution

Confirm where the promotion actually ran, whether stock arrived and whether the display or price was implemented.

6. Next decision

Specify what to repeat, adjust, investigate or stop, and assign the action to a person.

1. State the objective. Was the event intended to recruit shoppers, increase category contribution, support a launch, clear stock or defend a value position? Do not judge every event by promoted-item sales alone. Record the original objective before the results invite a more convenient explanation.

2. Challenge the baseline. Establish what performance might have been without the event, using an appropriate comparison. Consider seasonality, distribution, availability, price changes and overlapping activity. A modeled baseline is an estimate. Comparing with last week alone does not isolate the effect of a promotion.

3. Reconcile funding and costs. Distinguish agreed funding from claims still awaiting confirmation. Review the relevant discount, product cost, media, execution, logistics and waste implications using your organization’s financial definitions. Avoid counting the same supplier contribution twice or mixing retailer and manufacturer economics into one apparent return.

4. Look beyond the promoted line. Examine plausible cannibalization within the category, complementary purchases and changes before or after the event. A neighboring item’s decline is a reason to investigate, not proof of substitution. An uplift may also include purchases brought forward from a later period.

5. Test execution and supply. Confirm where the promotion actually ran, whether stock arrived, whether the product was available and whether the display or price was implemented. A store with constrained supply should not be treated as an unconstrained test of consumer response.

6. Record the next decision. Specify what to repeat, adjust, investigate or stop. Assign the action to a person and carry it into the next commercial and supply plan. A post-event slide deck is not the same as a changed decision.

This work complements existing technology. RELEX, for example, describes promotion analysis covering baseline sales, vendor funding, switching, stockpiling and halo effects. EIG’s contribution is the evaluation approach, operating context and cross-team decisions that make the analysis useful. RELEX promotion planning Platform references describe published capabilities, not EIG partnership or endorsement.

Turn a promotion review into the next event.

Retail promotion optimization connects evaluation with what changes next. Start with one event: its objective, dates, participating locations, sales and availability, funding and cost evidence, and the assumptions used in planning.

Plan the change

Record the proposed product, mechanic, timing or location change. Check funding, supply and execution constraints before approval.

Confirm execution

Keep the approved plan version and record actual dates, availability and deviations against the same event and locations.

Review the result

Apply the six checks above. Separate observed outcomes, estimated incremental effects and unresolved questions.

Decide the next event

Record what to repeat, adjust, investigate or stop. Name the approving owner and carry the change into the next plan.

A decision sequence, not proof of incremental profit. Keep the original plan, execution evidence and approved changes traceable.

Illustrative next-event record

A working example, not a client result.

Finding

Some participating stores received stock after the advertised start.

Proposed change

Review next-event timing and stock readiness before approving a repeat.

Evidence needed

Match receipts, availability and actual display dates by item and store. Keep constrained-store results visible rather than discarding them.

Decision owners

The commercial owner and replenishment lead agree the change, dependencies and approval.

Next review

Compare the next approved plan with what was executed, then apply the same six review checks.
