Quick answer

What Is Geofencing?

Geofencing is location-based mobile advertising. You draw a virtual boundary around a real place, and people whose phones enter that area can be shown your ads inside the mobile apps they use.

The fence can surround your store, a competitor’s location, a trade show or a conference venue. It relies on the GPS signal of a mobile device, and sometimes RFID, to know when a device is inside the boundary. The ad can run while the person is nearby, and the same device can keep seeing your message for up to 30 days after it leaves.

What makes geofencing different from most digital ads is that it targets where people actually go, not just what they type into a search box. For a step-by-step explanation, read How Does Geofencing Work?

How it works

From Fence to Foot Traffic in Four Steps

1

Define the area

We draw the fence around the place that matters: your location, a competitor, an event venue or a neighborhood. Fences can be as small as 1,000 square feet.

2

Build the audience

Devices that enter the area join your audience. We can set date and time windows, target one location or many, and reuse the audience later.

3

Serve the ad

Your ad appears inside mobile apps while people are nearby and for up to 30 days afterward, so the message lands when interest is high.

4

Measure visits

A conversion zone around your location records when a device that saw your ad walks in, so you can see real store visits.

Why geofencing

Advertising Based on Where People Actually Go

Search ads catch intent at the moment of a query. Geofencing catches behavior. Someone standing in a competitor’s showroom or walking a home expo has already shown you what they are interested in.

The big idea

Granular, local and measurable

Most ad platforms target by city, zip code or a radius tied to IP data. Geofencing works at the level of a single building or parking lot. That level of detail is something Google and Meta ads cannot match on their own.

Because the advertiser never sees a user’s age, gender or other personal details, geofencing also suits businesses with strict privacy rules, including healthcare organizations that must stay HIPAA compliant.

Your locationCompetitor sitesEventsConferencesNeighborhoods

Precise targeting

Ads only appear to people inside the zones you define, so fewer impressions go to waste.

Offline attribution

Conversion zones show how many people who saw the ad later visited your location.

Real-time relevance

Reach people when they are close by and ready to act, with offers that create a sense of urgency.

Repeat exposure

Reach people who pass through an area more than once, and keep your offer in front of them for up to 30 days.

Reusable audiences

Event and location audiences are portable, so you can use them again in later campaigns.

Ways to use geofencing

Where to Draw the Fence

The fence goes wherever your future customers already gather. These are the setups we use most.

Competitor conquesting

Win Customers From the Lot Next Door

Picture a car dealership. It fences a competing dealer’s lot, and every phone that spends time there sees a personalized offer from the dealership, both on the spot and for up to 30 days afterward. Those shoppers have already shown they want what you sell. Your job is to give them a reason to visit you before they sign somewhere else.

A conversion zone around your own showroom then shows how many of those devices actually came in. That is a clear, measurable way to grow market share and disrupt a competitor’s sales efforts.

See if geofencing fits

Event targeting, made simple

Fence a venue like a New Home Expo for the exact dates and hours of the show. Attendees comparing builders can see your ad during the event and after they head home. Single or multiple locations, with audiences you can reuse. See how home builders use it.

Conversion zones

Measure the Visits Your Ads Drive

A conversion zone is a second boundary drawn around your own location. When a device that was served your geofencing ad later enters that zone, the visit is recorded as an offline conversion for the campaign. That turns a question most advertisers guess at, whether the ads brought anyone in, into a number you can see.

Your reporting covers both the digital side and the physical side, so you can judge the campaign on real visits and cost per visit. Pair it with call tracking and web analytics to see phone and website leads alongside foot traffic.

Geofencing vs other targeting

How Geofencing Compares With IP Targeting and Search

Geofencing does not replace search ads. It fills a different gap. Here is how it stacks up against two common alternatives.

Geofencing
IP targeting
Location source
GeofencingThe GPS signal of the phone, which reflects where the device actually is
IP targetingThe registered location of an IP address, which may be a data center or proxy server
Accuracy
GeofencingPrecise down to a single site, with fences as small as 1,000 square feet
IP targetingCan be far off. Ashburn, VA has about 40,000 residents, yet Google Ads estimates its reach at more than 2 million because of the data centers there
Signal
GeofencingWhere someone physically went
IP targetingWhere an internet connection is registered

Search is different again. PPC search ads reach people based on what they type, which captures intent at the moment of a query. Geofencing reaches people based on where they physically go, often before they search at all. The two work well side by side.

Honest limits

What Geofencing Can and Cannot Do

We would rather you go in with clear expectations. Geofencing is powerful, but it is not a fit for every goal.

Privacy is built in

Advertisers never receive personal information about the people in a fence, such as age or gender. That is why healthcare organizations with HIPAA restrictions can use it, and why we follow current privacy guidelines on every campaign.

App-based only

Ads run inside mobile apps, so people who are not using apps in the area will not see them.

Multi-level buildings

A fence cannot separate floors, so every device in a multi-story building is targeted.

GPS accuracy

Tall buildings in dense areas can weaken GPS signals and reduce accuracy.

Privacy perceptions

Some people are wary of location-based ads, so the creative needs to feel helpful, not intrusive.

FAQ

Geofencing FAQs

1. How does geofencing work?

We draw a virtual boundary around a location. Mobile devices that enter it, detected through GPS, are added to your audience and shown your ads inside the apps they use, while nearby and for up to 30 days after. Read how geofencing works.

2. How small can a geofence be?

A geofence can cover an area as small as 1,000 square feet, which is precise enough to focus on a single building, store or lot.

3. Where do geofencing ads appear?

Geofencing ads appear inside mobile apps on phones and tablets. Because it is a mobile app based service, it does not reach people who are not using apps.

4. Can I target my competitors’ customers?

Yes. Competitor conquesting fences a competitor’s location so people who visit it can see your offer, and a conversion zone shows how many of them later visit you.

5. How do you measure geofencing results?

Conversion zones record a visit to your location as an offline conversion when a device that saw your ad walks in. Reports also include impressions, clicks, total spend, view-through and click-through visits, total visit rate and cost per visit.

6. Can geofencing target an event or conference?

Yes. We fence the venue for the dates and hours of the event, reach attendees during and after it, and can reuse the audience in later campaigns. It works for single or multiple locations.

7. Is geofencing more accurate than IP targeting?

Generally, yes. Geofencing uses the actual location of the device, while IP targeting relies on where an IP address is registered, which can be a distant data center or proxy server.

8. Is geofencing privacy friendly and HIPAA compliant?

Advertisers do not receive personal information such as age or gender about the people in a fence, which makes geofencing a practical option for healthcare organizations with HIPAA restrictions.

9. What are the limits of geofencing?

It only reaches people using mobile apps, it cannot separate floors in a multi-level building, and tall buildings in dense areas can reduce GPS accuracy. We plan fences with those limits in mind. See the pros and cons of geofencing.

10. Is geofencing the same as CTV advertising?

No. They are separate services. Geofencing reaches people on their phones based on where they go, while CTV places video ads on smart TVs in targeted households. Many businesses use both. Learn about CTV advertising.
