Geofencing for Retail: The SMS and Push Notification Playbook for Foot Traffic

Retail’s existential challenge is foot traffic. Online alternatives make the physical store visit optional for most categories — customers have to choose to come in. Geofencing creates a channel to influence that choice at the exact moment it is being made: when the customer is physically in the vicinity.

A shopper who is already at the shopping centre, already on the same street, already in motion — that customer has dramatically higher in-store conversion potential than a customer sitting at home. Geofencing identifies them and delivers a timely message that tips the decision toward a store visit.

Radius Strategy: How Far Out to Trigger

The optimal geofence radius depends on the store type, location, and customer journey:

200–500m radius — impulse purchase categories: Coffee, fast casual dining, convenience, bakeries. The customer is a short detour away. A trigger at this range prompts an immediate decision: “I’ll stop in on the way.”

500m–1km radius — planned purchase categories: Clothing, electronics, home goods, pharmacy. The customer has time to make a minor route adjustment. The message plants the idea that can convert a general shopping trip into a specific brand visit.

1–3km radius — destination retailers: Furniture, specialist sports equipment, large-format DIY. These stores require deliberate travel. The geofence radius covers a broader area because the customer is likely already in a “shopping” mode trip rather than passing by incidentally.

Competitor radius (variable): A geofence around a direct competitor’s location identifies customers considering the competition — and the triggered message must be compelling enough to redirect the visit.

The Foot Traffic Message Playbook

Near-store impulse trigger (SMS, <300m):

“[Name], you’re near [Store Name] — pop in today and get [specific offer]: [code or ‘show this message’]. Open until [time].”

Short. Direct. No preamble. The customer is nearby and has seconds to decide. The message must convey the offer and the instruction in under 10 seconds of reading time.

Shopping centre proximity trigger (push, 500m–1km):

“[Name] — heading to [Shopping Centre]? [Store Name] has [new arrivals / sale on / exclusive today-only offer]. Find us on [floor/location]: [link to map].”

The push notification can include a map thumbnail if the app supports it — reducing the friction of finding the store within the centre.

Weekend morning trigger (push, past-visit pattern + proximity):

Some CRM systems combine geolocation with temporal patterns — a customer who has visited the store on Saturday mornings 3 of the last 5 weeks receives a Friday evening push notification. “Your Saturday morning [Brand] visit — [weekend offer / new drop] is ready for you: [store link].” This is predictive proximity rather than real-time triggering, and can operate without live location data.

Cadence and Fatigue Management

Geofence triggers without frequency limits create the most intrusive mobile marketing experience possible. A customer who passes near a retail store every day on their commute should not receive a trigger message every day.

Recommended cadence controls:

• Minimum 72-hour cooldown per customer per geofence location
• Maximum 3 geofence triggers per week per customer across all locations
• Time-of-day filter: No triggers before 9am or after 8pm (or after store closing time)
• Engagement-based suppression: Customers who have not clicked on the last 3 geofence triggers are moved to a lower-frequency track until they re-engage
