How we’re bringing incremental sales measurement to Sponsored Search

As marketers face heightened scrutiny of their media budgets this year, many are expected to lean even more heavily into performance advertising. To deliver greater value to advertisers seeking measurable results, Walmart Connect is introducing incremental sales measurement to Sponsored Search.

While Walmart Connect’s solutions have expanded to support objectives across the marketing funnel, search advertising continues to be the cornerstone of any successful retail media strategy. As one of the leading retail platforms for many brands, Walmart offers unique opportunities to deliver measurable performance through search. That’s why it’s critical for advertisers to understand the incremental sales their campaigns are driving.

Our Search Incrementality solution helps answer a fundamental question: "Am I driving more sales than I would without advertising?" With the power of Walmart’s first-party retail data and industry-leading, test-and-control methodologies, advertisers will be able to gain clear, reliable insights they can trust. In a retail media landscape where many tools rely on third-party data or observational models, our approach stands out –offering a gold-standard methodology backed by real, verified sales data. We’re excited to deliver this powerful combination to give our advertisers greater confidence in the true impact of their campaigns.

With Search Incrementality, advertisers will be able to make sharper data-driven decisions about their channel investments. They can evaluate how current Sponsored Search strategies are driving incremental sales both online and in-store, identify top-performing brands within their portfolio, and reallocate budgets to meet demand –especially during key moments, like seasonal campaigns. Most importantly, they will be able to clearly and confidently report the incremental impact of their investments back to their organization.

"Search incrementality is a step forward for Clorox’s measurement partnership with Walmart Connect. At Clorox, we constantly seek to improve confidence and speed in our measurement tools. This new capability improves both for our Walmart search investment."

We plan to roll out more broadly to managed advertisers this summer, as we continue to learn more about how advertisers understand and optimize toward incrementality.
