Reaching real FMCG buyers: How to optimize campaigns with purchase behavior insights

In the battle for shopper attention, precision is everything. FMCG marketing teams are under more pressure than ever to deliver relevant, timely messages that drive conversion. Yet despite advances in digital targeting, Forrester Research analysis estimates that 37% of ad spend is wasted – often because campaigns could benefit from more granular, purchase-based audience insights that reflect real shopping patterns.

For FMCG marketers, defining audiences often starts with demographic profiles and self-reported data – both of which are essential for understanding shopper intent, attitudes, and preferences. To complement this, purchase behavior data provides the final step in the purchase journey: a view of what shoppers actually put in their baskets, especially in categories where most purchases happen offline. Together, these insights help drive more effective FMCG campaigns that align with real-world habits.

Why purchase behavior matters

FMCG audience targeting becomes more effective when it's enriched with real purchase behavior – the strongest signal of future shopping choices. While demographic, attitudinal and intent data help define who shoppers are and what motivates them, verified purchase data shows what goes into their baskets, offering FMCG marketers a powerful edge.

For fast-moving consumer goods (FMCG) in particular – products bought regularly in supermarkets, discount chains, or drugstores – understanding what people really buy is key to unlocking relevant, high-performing campaigns. Whether you're promoting bottled water, skincare, frozen meals, or pet food, one of the best indicators of future behavior is past behavior.

So how can FMCG marketers reach real category buyers?

From purchase insights to powerful audience activation

Using purchase-based audience targeting, FMCG brands can engage actual buyers – across any category – through digital campaigns, even when those purchases occur offline. Go beyond assumptions by targeting people with a proven purchase history in your category, brand, or even your competitors.

This approach opens the door to a range of strategies aligned to your business goals:

• Increase market penetration by targeting category buyers who haven't previously purchased from your brand
• Boost market share by focusing on buyers of your competitor’s products or private labels
• Build loyalty with tailored messaging to low- or medium-frequency buyers

This isn't guesswork. It's real-world behavior, turned into actionable digital audiences.

The power of shopper data

What makes this possible? The foundation is our shopper panel – one of the largest continuous purchase behavior tracking panels in the industry. For decades, we've monitored shopping habits across nationally representative samples in key European markets. Built on trust and transparency, this privacy-safe data provides a deep view into actual shopper behavior.

The result is a direct line between what FMCG shoppers buy and who you target.

Example use case: Identify consumers regularly purchasing energy drinks or premium skincare products and activate these audiences online with high precision.

How does shopper audience targeting work?

Here's how the process turns real-world shopping data into campaign-ready digital audiences:

1. Define your target audience
   Choose your segment based on product categories, brands, spend level, frequency, or even retail channel – combined with media habits and attitudes if needed.
2. Seed audience creation
   Shopper panel data is used to build the initial "seed" audience of real buyers.
3. Look-alike modeling
   Our ID partner expands this seed group to a scalable audience using look-alike modeling techniques.
4. Distribution to media platforms
   The enriched target audience is made available on relevant demand-side platforms (DSPs) for activation across programmatic channels.

Activating audiences based on verified purchase behavior gives FMCG marketers a smarter, more strategic way to engage shoppers. Whether you're driving market penetration, switching, or loyalty, this method helps ensure your message reaches the people who are most likely to act – because they've already shown intent to purchase where it matters: at the shelf.

What are the benefits of shopper audience activation:

• Precision: Reach your real buyers
• Efficiency: Reduce wastage by avoiding non-relevant audiences
• Relevance: Deliver tailored creative based on shopper behavior
• Scalability: Activate audiences across your entire category

These benefits become even more powerful when integrated into your media buying strategy. By feeding shopper data into programmatic advertising platforms, brands can identify the right audiences and deliver messages at the right time, in the right context.

You gain impact and efficiency at scale:

• Automated, cost-efficient bidding
• Smarter targeting via machine learning
• Real-time optimization based on performance data
