The Five Decisions That Define Every Geofencing Campaign
Before you draw your first geofence, you need to make five foundational decisions that will determine whether your campaign succeeds or fails. These are not technical settings — they are strategic choices that require thought, not just clicks.
Step 1: Define Your Campaign Objective
Every geofencing campaign should have one primary objective. The most common are: drive foot traffic to a physical location, generate leads or form submissions, build brand awareness in a target market, or conquest customers from competitors. Your objective determines everything else — which locations to fence, what creative to run, and how to measure success.
Step 2: Select Your Geofencing Locations
Location selection is the most important variable in geofencing. A mediocre creative at the right location will outperform brilliant creative at the wrong location every time. For each location you are considering, ask: Are the people here likely to need my product or service? Are they in a mindset to receive advertising? Is there enough foot traffic to build a meaningful audience?
The three highest-value location categories for most advertisers are: competitor locations (people already shopping your category), intent-signal locations (hospitals for healthcare, courthouses for legal, car lots for automotive), and proximity locations (within 1-2 miles of your own location).
Step 3: Set Your Audience Rules
Once you have selected your locations, define the rules for who gets added to your audience. Key parameters include dwell time minimum (how long must a device be in the fence to qualify — typically 5-20 minutes), lookback window (how far back in time should visits count — typically 7-90 days), and visit frequency (minimum number of visits required — 1 for broad reach, 2+ for higher intent).
Step 4: Build Your Creative
Geofencing ads run across the mobile web and in-app inventory. The two most important sizes are 300x250 (medium rectangle) and 320x50 (mobile leaderboard). Your creative must communicate your message in under 3 seconds — most users spend less than 1.5 seconds looking at a mobile display ad before scrolling past. Lead with your strongest visual, include a clear value proposition, and end with a single, frictionless CTA.
Step 5: Set Up Measurement
Before you launch, set up your measurement infrastructure. At minimum, create a conversion zone around your own location to track foot traffic lift. If you have a website, install pixel tracking to measure online conversions from geofencing audiences. Set up call tracking if phone calls are a key conversion action. Define your KPIs and baseline metrics before launch so you have a clear benchmark to measure against.
Step 6: Launch and Monitor
Launch your campaign and monitor daily for the first week. Check impression delivery (are you hitting your target volume?), CTR (is your creative resonating?), and conversion zone visits (are exposed devices visiting your location?). Most geofencing campaigns need 2-4 weeks to accumulate enough data for statistically valid optimization decisions.
Common Setup Mistakes to Avoid
The most common geofencing setup mistakes are: fencing too large an area (larger than 1 mile radius dilutes audience quality), not setting a dwell time minimum (captures drive-by devices that have no intent), running the same creative for 30+ days without refreshing (ad fatigue reduces CTR by 40-60% after 3-4 weeks), and not setting up conversion zones before launch (makes it impossible to measure foot traffic lift).
