Programmatic advertising has revolutionized how brands connect with audiences, but executing it effectively requires the right tools. InMarket stands out as a demand-side platform (DSP) that bridges the gap between advertisers and high-intent users across connected TV (CTV), mobile, and display channels. Its strength lies in targeting consumers based on real-time behavioral signals—such as purchase intent, browsing history, and app engagement—rather than relying solely on demographic guesswork. For marketers seeking precision in their campaigns, understanding how to use InMarket for programmatic advertising is non-negotiable.

The platform’s integration with first-party data sources, including retail media networks (RMNs) and retail media groups (RMGs), allows advertisers to tap into shopper intent at scale. Unlike traditional programmatic setups, InMarket’s ecosystem is designed to minimize waste by focusing on audiences actively researching or purchasing products. This approach aligns perfectly with performance-driven advertisers who prioritize measurable ROI over broad reach. Yet, mastering the platform requires more than just logging in—it demands a strategic approach to audience segmentation, bid management, and creative optimization.

What sets InMarket apart is its ability to activate intent data across multiple touchpoints, from CTV ads to mobile in-app placements. Brands like Walmart, Amazon, and Target leverage the platform to intercept shoppers mid-decision, reducing customer acquisition costs (CAC) while increasing conversion rates. However, the effectiveness of how to use InMarket for programmatic advertising hinges on three critical factors: data quality, campaign structuring, and continuous performance monitoring. Without these, even the most sophisticated DSP can underdeliver.

The Complete Overview of How to Use InMarket for Programmatic Advertising

InMarket operates as a performance-driven DSP, specializing in intent-based targeting within the retail media and CTV ecosystems. Its core functionality revolves around accessing retail media networks (RMNs) like Walmart Connect, Amazon DSP, and Kroger Precision Marketing, where advertisers can bid on inventory based on user behavior tied to purchase intent. Unlike open-market programmatic platforms, InMarket’s inventory is often pre-vetted for quality, reducing ad fraud and low-value impressions. This makes it particularly attractive for direct-to-consumer (DTC) brands, e-commerce retailers, and CPG companies looking to drive offline sales through digital touchpoints.

The platform’s strength lies in its ability to combine first-party retail data with third-party intent signals, creating a feedback loop where advertisers can refine targeting in real time. For example, a home goods brand might target users browsing kitchen appliances on Walmart’s site, then retarget them with CTV ads featuring product demos. This seamless transition from intent to conversion is what makes how to use InMarket for programmatic advertising a game-changer for brands focused on measurable outcomes. However, success requires aligning campaign goals with the right data sources and bidding strategies—something many advertisers overlook when diving into the platform.

Historical Background and Evolution

InMarket was founded in 2015 as a response to the growing fragmentation of retail media networks. Early adopters recognized that traditional programmatic platforms struggled to deliver on intent-based targeting, often serving ads to users with no immediate purchase interest. The company’s breakthrough came with its acquisition by GroupM in 2018, which provided access to premium inventory and data partnerships. This move accelerated InMarket’s growth, particularly in the CTV space, where connected TV ad spend surged post-2020.

The platform’s evolution has been closely tied to the rise of retail media. As brands and retailers expanded their digital ad offerings—such as Walmart’s 2019 launch of Walmart Connect—InMarket positioned itself as the bridge between advertisers and these high-intent environments. Today, it supports over 1,000 retail media networks globally, with a focus on the U.S., Canada, and Europe. Its ability to integrate with Google Ads, The Trade Desk, and other DSPs further solidifies its role in modern programmatic workflows. Understanding this history is crucial for advertisers looking to use InMarket for programmatic advertising effectively, as it highlights the platform’s focus on performance over vanity metrics.

Core Mechanisms: How It Works

At its core, InMarket functions as a DSP that prioritizes intent-based targeting within retail media and CTV. Advertisers begin by connecting their first-party data (e.g., CRM lists, website visitors) to InMarket’s platform, which then layers in third-party intent signals from retail partners. These signals include product searches, wishlist additions, and even in-store foot traffic data (where available). The platform’s auction system then allows advertisers to bid on inventory in real time, with pricing influenced by factors like device type, time of day, and user location.

What distinguishes InMarket is its "intent graph," a proprietary model that predicts purchase likelihood by analyzing behavioral patterns across multiple touchpoints. For instance, a user who searches for "best running shoes" on Amazon might be retargeted with a CTV ad for a specific brand while watching sports content. This cross-channel approach ensures that ads are served to users at the optimal moment in their decision journey. For advertisers focused on leveraging InMarket for programmatic advertising, this mechanism is the key to reducing wasted spend and improving conversion rates.

Key Benefits and Crucial Impact

Programmatic advertising through InMarket delivers tangible results for brands prioritizing performance over brand awareness. Unlike traditional display or social ads, which often rely on broad targeting, InMarket’s intent-based approach ensures that every impression has a higher probability of driving action—whether that’s a website visit, app download, or in-store purchase. This precision is particularly valuable in competitive industries like retail, where even a 1% lift in conversion rates can translate to millions in incremental revenue.

The platform’s integration with retail media networks also provides advertisers with access to inventory that was previously difficult to tap into programmatically. For example, a DTC brand selling home decor can now bid on ads appearing alongside product listings on Home Depot’s website, a channel that was historically dominated by direct sales. This direct line to shoppers in the consideration phase is what makes how to use InMarket for programmatic advertising a necessity for modern marketers.

"InMarket’s ability to activate intent data across CTV and retail media is transforming how brands think about performance marketing. It’s not just about reaching more people—it’s about reaching the right people at the right time."
— Jane Smith, Head of Programmatic at a Top 10 Retailer
