- Google says Gemini powers the buying, campaign execution and full-funnel measurement, and helps prevent overexposure.
- In early testing with Unilever's Hellmann's and WPP Media, Google reports a 24% increase in unique reach and a 25% reduction in cost per unique user.
- Rollout dates were not given in the announcement we read.
Impact Layer
- What changed
- Google's DSP can now buy and measure vertical video across publishers and channels as one, using Gemini to run the process.
- Why it matters
- Vertical video is spread across social and publisher apps, so one place to buy it with shared frequency control is attractive, and it adds to Google's role in programmatic buying.
- Who is affected
- Brand and agency teams that buy programmatic video, and independent DSPs and social platforms competing for vertical video budgets.

On September 28, 2026, Google introduced Vertical Video Unification with Display & Video 360 (DV360), its programmatic buying platform. It lets advertisers buy and measure vertical video across multiple channels in one place.
What Google says
- Gemini powers the buying process, campaign execution and full-funnel measurement, and helps prevent ads from being shown to the same people too often.
- In initial testing with Unilever’s Hellmann’s brand and WPP Media, Google reports a 24% increase in unique reach and a 25% reduction in cost per unique user.
- Executives from Unilever and WPP Media are quoted in the post. The announcement did not give rollout dates in the text we read.
What is not stated
MarTech Edition notes that the announcement leaves the points of human control unspecified. The test sample, duration and campaigns were not described, and the results are Google’s own.
Our read
Vertical video buying is fragmented across social and publisher inventory, and frequency is hard to control across it. Putting the buy and the measurement in one platform is the sensible fix, and it also makes Google’s DSP a stronger place to run video. Buyers should ask who verifies the reach figure and whether it can be reproduced outside Google’s reporting, then run a controlled test before moving budgets.
