What is Geofencing Marketing?
Geofencing marketing is a location-based advertising strategy that uses virtual boundaries – commonly called geofences – to deliver targeted promotional messages or offers to consumers within specific physical areas. These digital perimeters can encompass an entire city, a zip code, a retail corridor, a single store location, or a radius around a defined place. Geofencing allows brands to create optimized ad campaigns that engage audiences at the moment of highest relevance – thereby improving efficiency, boosting conversion rates, and maximizing return on ad spend (ROAS).
Geofencing marketing is often implemented through mobile push notifications or online search ads, but it can also work in tandem with offline media – such as billboards, direct mail, out-of-home (OOH) placements and local print ads – by layering messaging and increasing recall.
Why Geofencing Marketing Matters
- Precision-level targeting: Virtual boundaries allow for focused ad delivery to audiences in the most relevant areas – reducing wasted impressions and wasteful spend.
- Contextually relevant engagement: Messages delivered when individuals are physically near a business, billboard, or relevant venue can feel timely and actionable – leading to higher engagement or immediate response.
- Stronger online-to-offline attribution: By targeting audiences in predefined locations, brands can more directly link their campaigns to real-world customer visits, measure advertising impact, and refine strategy as needed.
- Data-driven cost efficiency: Increase conversions and drive efficient media spend by focusing campaigns on areas where an audience shares favorable demographic or psychographic characteristics.
To sum it up, geofencing marketing offers businesses a tool to align their advertising dollars more closely with real-world consumer behavior and local audiences.
How Does Geofencing Marketing Work in Practice?
1. Determining the Geographical Area to be Targeted
The first step is defining the geofence, i.e., the physical boundary that will be used for targeting. Accuracy here is critical – an area too small may miss valuable audiences; too large may include irrelevant users and dilute efficiency.
Several common methods include:
- Pre-defined geographic areas: Using markets such as a city, state, ZIP/postcode, or a DMA/CBSA to cast a geo-net.
- Specific venues or buildings: Creating a polygon representing a store, shopping centre, or corridor by defining its coordinates (latitude/longitude).
- Radial geofences: Drawing a circle around a location (e.g., a restaurant or store) with a fixed radius or a drive/walk time boundary.
- Foot traffic derived trade areas: Using location intelligence to identify the true trade area of a venue (for example the census block groups where visitors come from), and then creating a geofence that encloses the highest-value zones. This method tends to minimize both under- and over-inclusion of audiences.
2. Segmenting the Geofenced Audience
Once the spatial boundary is defined, the next step is to characterise the audience within that zone. This means analysing demographic, psychographic and behavioural data of the people who reside in, visit, or pass through that area.
For example:
- Age groups, household composition, income levels, lifestyle or purchase behaviour.
- Time of day or day of week when the highest foot traffic occurs.
- Proximity to competitors, crossover segments, look-alike zones.
Audience segmentation allows for tailored messaging – e.g., if a fitness-store’s trade area shows a large share of families with children, the campaign message might focus on “active kids gear” rather than basic athletic wear.
Audience segmentation also helps validate the geofence and confirm that the visitors passing through align with the intended target audience.
3. Launching the Campaign and Measuring Performance
With boundary and audience defined, the campaign setup can proceed:
- Offline campaigns might include placing billboards in the geofenced zone, distributing direct-mail in the defined neighbourhoods, or installing OOH media along targeted routes.
- Digital campaigns might include mobile display ads, push notifications, in-app messages, or connected-TV ads triggered by device presence in the geofence.
- Measure performance: For example, assigning unique promo codes, tracking click-throughs, foot traffic lifts, dwell times, and cost per acquisition (CPA).
Location Intelligence-Driven Geofencing Marketing in Action
Imagine you run a local bakery specialising in hand-decorated cupcakes and high-protein treats for fitness-minded customers. You want to launch a direct-mail campaign and also run mobile ads within the surrounding neighbourhoods – but you also want to maximize ROAS and minimize wasted spend.
Here’s how a location intelligence-driven geofencing strategy might play out:
- You analyse your existing visitor data (via foot-traffic analytics) and discover that a significant portion of your customers come from three particular Census block Groups (CBGs) rather than the broader zip code area.
- You create a custom geofence that maps those CBGs (i.e., draw polygons around those regions).
- You analyse nearby competitor areas (perhaps other bakeries or dessert cafés) and identify zones where you have overlapping audience bases – then include those in your geofence expansion.
- You segment the audience within the geofence: you discover that many customers are young professionals who visit after work, and families who come on weekends. You craft two separate messages: one targeting “evening indulgence for pro-athletes” and another “family weekend treat”.
- On the digital side, you implement mobile display ads and push notifications that trigger when devices enter the geofence during key hours (late afternoon or weekend mornings). On the offline side, you mail flyers to households within the same geofence offering a “first-visit discount”.
- Post-campaign, you compare before and after foot traffic to your bakery and look for visit surges during key hours you identified. You also track redemption of promo codes, and monitor cost per acquisition and ROAS.
The result: more efficient ad spend, higher conversion from relevant zones, and a clearer link between location-based advertising and physical outcomes.
