Real-Time Store Visits Are Now a Programmatic Currency

For years, advertisers ran campaigns and waited. Then, at the end of the month, a report would tell them which stores people visited after seeing an ad. By that point, the budget was spent, the campaign was over, and the insight was too late.

That wait is ending. A new partnership between InMarket and Yahoo DSP, announced on April 23, 2026, means advertisers can now see store visit data every single day and automatically adjust their campaigns while they are still running.

This is not a minor upgrade. It changes the fundamental logic of how digital ad spend gets validated.

From Monthly Reports to Daily Signals

Here is how it works in plain terms. InMarket tracks real-world store visits (not GPS guesses, but observed behavior matched to actual people) and sends a daily feed of that data into Yahoo's advertising platform. Yahoo's AI system, called Yahoo Blueprint, reads those signals and automatically tweaks bids and ad delivery in real time.

The result: if your ads are driving people into stores today, the system notices and doubles down. If they are not working, it adjusts before more budget is wasted.

"Marketers today are under increased pressure to prove the impact of their advertising efforts," said Michael Della Penna, Chief Strategy Officer at InMarket. "Our partnership with Yahoo DSP offers advertisers the insights they need to track how ongoing exposure to their various advertising tactics are impacting KPIs, allowing them to make critical changes to optimize their campaigns while they are still in flight."

Why This Matters Beyond the US

The partnership currently covers the US and Canada. But the commercial pressure it responds to is global, and APAC is feeling it acutely.

Asia-Pacific digital ad spend is projected to reach US$489.3 billion by 2029, with location-based advertising in the region growing at a 19.2% annual rate. Retail and quick-service restaurant brands across Southeast Asia are under the same accountability pressure as their US counterparts: prove that digital ad spend is actually moving people through the door, not just moving pixels across a screen.

The technical architecture being validated here, daily visit signals feeding automated optimization, is the model that will arrive in Singapore, Bangkok, and Jakarta as local data infrastructure catches up. The question for APAC marketing leaders is not whether this becomes standard practice. It is how quickly they will be expected to operate at this standard.

The Race to Make Offline Data a Trading Signal

This announcement did not happen in isolation. One day earlier, PayPal Ads launched closed-loop purchase attribution for connected TV. Around the same time, NIQ and Adsquare made real purchase-based audience data available for programmatic campaigns. The pattern is clear: the industry is racing to make offline conversion data as tradeable and real-time as clicks.

Yahoo is building this systematically. InMarket handles retail, QSR, and automotive visit data. Circana, a separate Yahoo DSP partner, handles CPG purchase conversions. Together, they create a measurement platform that rivals what holding company mergers like Omnicom-IPG are trying to consolidate internally.

"As we continue to evolve our In-Flight Outcomes solution, this partnership with a recognized leader in in-store visit measurement enables more timely and informed omnichannel decision-making across key verticals, including retail, QSR, and automotive," said Emily Ray, Sr. Director of Business Development at Yahoo DSP. "InMarket's capabilities complement our broader approach, helping advertisers better understand and maximize campaign performance."

What This Means for Marketers

71% of advertisers now rank incrementality (proving that ads actually caused a behavior, not just correlated with one) as their top performance metric for retail media investments. That number reflects a hard shift in accountability standards.

US programmatic spend is crossing US$203 billion in 2026. Retail media alone is approaching US$69 billion. At that scale, end-of-month attribution reports are no longer acceptable. Clients want proof, and they want it in time to act on it.

For APAC agency planners, the InMarket-Yahoo DSP partnership is a preview of the infrastructure they will need to build or buy access to. The advertisers who close the loop between digital impressions and in-store behavior, in real time, will have a structural advantage over those still waiting for monthly reports.
