From Purchase to Performance: Enhancing Sell-Side Targeting and Measurement at Scale

As digital advertising becomes more outcome-driven, one challenge remains stubbornly hard to solve: connecting media exposure to actual purchase behavior. Clicks and impressions can point marketers in the right direction, but they rarely tell the full story of what led to a sale.

That is what makes Media.net’s new partnership with Fetch so important. Through SELECT for Commerce (its curation platform), Media.net is creating a framework to bring commerce data partners into its ecosystem and connecting real, scaled purchase data with sell-side targeting and optimization to enhance performance.

Fetch is the inaugural partner in that effort, setting the stage for a broader commerce-data strategy that extends beyond a single provider.

“Advertisers are moving beyond proxies and looking for signals that reflect real consumer behavior,” said Karan Dalal, COO, Media.net. “What makes this partnership with Fetch especially compelling is the ability to bring observed purchase data into both activation and measurement, lighting up a clearer connection between media exposure and business outcomes on the open web.”

Fetch is a leading rewards app and outcomes-based advertising platform with item-level, retail agnostic visibility into both online and in-store consumer purchases across payment methods. With more than 13 million receipts scanned every day, totaling $212 billion in gross merchandise value each year, Fetch brings unmatched scale to commerce data. This creates a unique opportunity for advertisers to connect purchase behavior with media performance across display, video, CTV, and audio.

SELECT for Commerce: Turning Transaction Data Into Audience Activation

On the activation side, Media.net is integrating Fetch’s audience data into its curation platform through SELECT for Commerce. This gives advertisers and curators access to audiences built from verified transaction behavior, moving beyond inferred intent to signals grounded in what consumers are actually buying.

Because Fetch captures purchase behavior across retailers and categories, it adds a deeper layer of commerce intelligence to sell-side targeting. Combined with Media.net’s SearchSignals - which help surface precise user intent for targeting - advertisers can build and activate audiences with a strong blend of intent and observed purchase behavior for better performance, including in channels like CTV.

ELEVATE for Measurement: Connecting Media Exposure to Outcomes

The partnership also expands Media.net’s capabilities through ELEVATE for Measurement – its sell-side measurement offering.

ELEVATE helps advertisers understand which signals around an impression - including context, placement, publisher, and intent - are actually influencing performance. By bringing Fetch’s transaction data into a privacy-safe clean-room environment, Media.net can measure campaign exposure against actual purchase activity without direct access to user-level transaction data.

“As one of the most robust sources of verified purchase behavior data, we know how powerful real purchase signals can be for marketers,” said Daniel Block, GM, Data Revenue & Partnerships at Fetch. “This partnership with Media.net brings those signals into the open web to make targeting and measurement more grounded, actionable, and reflective of actual consumer behavior.”

The result is a more complete view of how campaigns influence real-world outcomes. Over time, this combination of commerce data and sell-side insights can help advertisers understand which environments, signals, and strategies are driving stronger results and scale what works to achieve repeatable outcomes.

Connecting Context to Commerce at Scale – Building a More Accountable Open Web

Together, SELECT for Commerce and ELEVATE for Measurement bring audience activation and sell-side measurement closer together in a way that is scalable, privacy-conscious, and grounded in real consumer behavior.

More importantly, this partnership reflects where advertising is headed. Advertisers are looking for higher quality signals - they want a clearer understanding of what drives outcomes, and the ability to act on those insights. By combining multi-retailer transaction signals, contextual intelligence, SearchSignals, and sell-side measurement, Media.net is helping build a more transparent and accountable path from impression to purchase. This partnership with Fetch is the first step in that broader vision.
