Geofence Event Targeting FAQ

Answers to your most common questions about launching a campaign.

GENERAL OVERVIEW

What is Geofence Event Targeting?
Geofence Event Targeting is a location-based advertising strategy that uses GPS to create a virtual boundary—or 'geofence'—around an event venue. When mobile devices enter that boundary, Shared Audiences can serve digital ads to those users in real-time, and continue to retarget them up to 30 days after the event.
Who is this service ideal for?
This service is most effective for B2B marketers, event sponsors, exhibitors, or brands who want to engage attendees of trade shows, conferences, expos, or other in-person gatherings with timely, targeted digital advertising.
What makes Shared Audiences' solution unique?
Our platform delivers building-level precision targeting, flexible post-event retargeting, full reporting transparency, and consultative guidance. We also support campaigns globally and work closely with clients on setup and strategy.

HOW IT WORKS

View full How It Works page →
How do you capture event attendees?
We draw a digital geofence around the event venue using precise GPS coordinates. When a device enters, we capture its mobile ID — building a verified audience of attendees you can target immediately.
How do you engage attendees with ads?
Your creative shows up across every screen your audience uses next — display banners and native ads, short-form video, and full-screen CTV storytelling on streaming platforms.
How do you measure campaign performance?
Track performance in real time — impressions, clicks, CTR, and even foot traffic from ad exposure to physical visits using conversion zones — so you know exactly which ads and audiences drive real-world results.
How do you retarget attendees after the event?
After the event, we keep your brand in front of attendees for up to 30 days while they're evaluating, deciding, and buying.

TARGETING & RETARGETING

How does geofence targeting work?
We define precise virtual perimeters around a venue, hotel, or area. Devices that enter the geofenced location are anonymously tracked, and ads are served to them while present and for 30 days afterward.
Can we retarget the same audience after the event?
Yes. Devices captured during the event are eligible for retargeting for up to 30 days. You can use different creatives and landing pages during this period to match post-event goals.
Can we target hotels, streets, or other locations?
Absolutely. You can include surrounding hotels, lounges, or adjacent venues in the campaign. Each campaign can include up to 25 geofence polygons and 5 conversion zones for foot-traffic attribution.
Is international geofencing supported?
Yes. We can geofence any event around the world. The number of mobile IDs that can be captured will vary significantly outside the U.S. due to privacy regulations.

TRACKING & REPORTING

What kind of reporting is available?

You will receive comprehensive performance reporting that includes:

  • Total impressions delivered
  • Click-through rates (CTR) by ad unit
  • Unique devices reached
  • Foot-traffic conversions
  • Domains and apps where ads were served
What kind of CTR should we expect?
The industry average for CTR in display advertising is around 0.06–0.08%. Our geofenced campaigns frequently exceed this, with some reaching 0.80% or higher, depending on creative quality and relevance.

CREATIVE STRATEGY

Can we change ad creatives after the event?
Yes. Many customers choose to run one version of ads during the event (with booth number, giveaways, or live CTAs) and then switch to a new set of creatives post-event focused on lead capture or demo requests. You may change your ad creative up to 3 times per campaign.
What should our ads focus on?
  • During event: Promote booth number, product demos, giveaways, or speaker appearances.
  • Post-event: Highlight follow-up offers, demo bookings, or value-based content (e.g., whitepapers, case studies).

CUSTOMER SUPPORT

Will we have a dedicated point of contact?
Yes. A Shared Audiences team member will be assigned to your campaign and serve as your ongoing contact for setup, delivery, and reporting.
How quickly can you respond to questions or updates?
We prioritize responsiveness and will reply promptly via email. For urgent issues, we typically respond same-day.
What happens if we miss a deadline?
We’ll make every effort to accommodate late submissions, but delays may impact launch timing or ad approvals. We strongly recommend meeting the outlined deadlines.

MISCELLANEOUS

Can you show us where our ads appear?
Yes. We can provide previews and mockups showing your ads on sample publisher sites, as well as live data on top-performing placements.
Can we test multiple messages in one campaign?
Yes. You may submit several creatives for A/B testing or multi-message targeting. The platform will optimize delivery based on performance.
Do we need to use a tracking pixel?
No, but we highly recommend it. Without the pixel, you’ll miss view-through conversion data and full campaign attribution.
