Simple idea: people don’t buy categories; they enter them. Category Entry Points (CEPs) are the cues (moments, needs, places, companions) that put a shopper in-market now. Link your brand to more of these moments, and you get thought of more often. Get thought of more often, and you sell more. That’s mental availability, not mythology.

Spark Moments

Plain truth: people don’t buy categories. They buy in moments. At Footprints AI we call these moments Shopping Occasions = the real-world triggers that put someone in-market now. In marketing science, these triggers are Category Entry Points (CEPs). Shopping Occasions are how we operationalize CEPs.

Imagine your ads showing up exactly when a shopper thinks, “I need this right now.” Shopping Occasions are those simple life triggers that open the door to purchases. In retail media, these moments turn your spend into outsized results. Using Footprints AI’s shopper insights, here’s a straightforward guide: what they are, why they boost ROAS (return on ad spend), and practical examples.

The Small Doors That Open Big for Retail Media

• CEPs build mental availability. CEPs are the building blocks of mental availability: what buyers think as they enter a buying situation. More relevant CEP links → higher chance your brand is recalled and chosen.
• More CEPs, less churn. In multi-category data, each additional CEP linked to a brand reduces defection probability. Memory links are commercial assets.
• Being present with the CEP matters. Buyers build links when the brand is exposed alongside the CEP. Your media must name the moment.
• Retail media closes the loop. It ties ad exposure to verified sales—on- and off-site—so you can see which CEP-aligned plays actually shift baskets.

The Core Idea for Brand Managers: own more of these moments with retail media → get picked more often → basket incidence goes up → ROAS goes up.

What Is a Shopping Occasion?

A repeatable, predictable buying moment defined by mission + timing + context.

Examples we see every week:

• Monday Top-Up (small basket, essentials, 6–9 pm)
• Sweet Friday (11–14, suburban women 32–37, wine + baking + condoms)
• After-Payday Stock-Up (1st–5th of month, big baskets)
• Lunch Rush (12–14, convenience, ready-to-eat)
• Game Night (Fri–Sun 18–22, snacks + beer + soft drinks)
• School Prep (Aug–Sep 17–20, lunchbox + dairy + bakery)
• Sunday Reset (home care + fresh, 10–13)
• Rainy Day Comfort (weather trigger, soups + tea + bakery)
• Post-Workout (gym-adjacent stores, 17–20, protein + hydration)
• Newborn Week 1 (new parents CRM, diapers + wipes + gentle detergent)

Each occasion is a Category Entry Point in plain clothes, a moment you can target, measure, and scale.

The 3 Rules

1. Name the moment in the copy. Don’t hint it. Say it. (Make the CEP explicit.)
2. Place it where/when it happens. Daypart, store by store, weekday, weather, mission. (Match media to the CEP window.)
3. Prove it in sales. Closed-loop or it didn’t happen. (Report ROAS by CEP.)

The Playbook

1. Map the CEPs. Start with Why/When/Where/With whom/With what. Validate via qual + quant; rank by frequency, contestability, and fit. Track four metrics: mental penetration, mental market share, network size, share of mind.
2. Name the moment in the message. Put the CEP in the line. Don’t imply “post-workout”; say it. “Just finished your run? Protein without the chalk.” That’s how you build the memory link.
3. Place media where the CEP happens.
4. Prove it with closed loop. Design every CEP test with exposure cohorts, clean windows, and sales KPIs (uplift vs control; incrementality; frequency vs waste). Follow IAB/MRC guardrails for attribution windows and modeled unknowns.
5. Scale CEP coverage. Treat each validated CEP like a new distribution point in memory. Add one, measure lift, then add the next. Compound gains over quarters.

Metrics That Matter (keep it tight)

• ROAS = Revenue / Ad Spend (report by occasion/CEP)
• Incremental Units / 1K Impressions (gold metric for in-store)
• CVR Lift vs Generic (per Occasion Card)
• New-to-Brand % (widening the base)
• Attach Rate (did the bundle happen?)
• CEP Coverage (# of priority CEPs where your brand is first choice/top converter)

Shopping: The Everyday Triggers That Drive Buys

Shopping Occasions are simply the why and when behind a purchase. Footprints AI, using AI-powered insights from billions of transactions, detects missions and moments tied to life stage, weather, and events. It’s like mapping a shopper’s day: quick fridge top-ups, family meals, festival prep.

From the Footprints AI playbook:

• Dinner Top-Up: the quick dash for essentials: snacks or drinks after work. Think: evening rush for cold beers on a hot day.
• Comidas de fin de semana: tiempo en familia: abasteciéndose para una barbacoa con carne, especias y refrescos.
• Necesidades urgentes: heatwave hits → ventiladores, helados, y water surge.
• Ocasiones especiales: temporada de festivales → gafas de sol, atuendos, snacks de viaje.
• Misiones de almacenamiento: el gran acarreo mensual (menos común en verano cuando los compradores compran sobre la marcha).

Estos no son aleatorios. Los atamos a etapas de la vida (por ejemplo, familias con niños compran más bocadillos) y ritmos (por ejemplo, el pico de los viernes para la preparación del fin de semana). ¿Por qué preocuparse? Debido a que la segmentación de estos momentos en los medios minoristas significa que su anuncio aparece cuando la mente del comprador está abierta, lo que aumenta los clics, las compras y el ROAS.

Las ocasiones de compras son las pequeñas puertas que abren grandes ventas.
