How to use geofencing to maximize conference and event attendance

B2B conferences require significant investment in budget, time, and team resources. Yet most event measurement still relies on surface-level metrics like booth scans or badge swipes.

These signals tell you who showed up, but not whether that presence translated into real buying intent. 

What if you could target all event attendees and translate real-world presence into measurable digital behavior at the contact level? That kind of visibility unlocks intent signals traditional event tracking can’t, such as:

  • Who engaged
  • When they engaged
  • How event attendance influenced their buying journey

With these insights, events shift from passive brand moments to active intent-generation opportunities, enabling timely follow-up and more effective sales activation. To gain access to that level of visibility, geofencing becomes a critical part of your event strategy. 

Events are a perfect use case for geofencing

Geofencing lets you reach users within a defined physical radius, such as a conference venue, a hotel, or a nearby district.

Events are uniquely suited to geofencing because they offer:

  • A dense concentration of ICPs
  • Known venues and predictable timing
  • Clear contextual relevance

Instead of guessing intent from firmographics or session attendance, geofencing captures intent from verified proximity and real-world behavior. You’re reaching buyers because they are there, in the moments that matter most. This creates a powerful combination of interest + location, which increases relevance, engagement, and downstream impact.

Location-specific opportunities for relevant event targeting

Not all geofences are equal. The most effective event strategies use multiple, purpose-built locations to extend reach and capture intent throughout the event lifecycle. When seeking to maximize event-focused geofencing, there are a few key areas to target.

Conference and expo venues

For core event attendance tracking, you’ll want to geofence at the source, and that means the event itself, including:

  • Convention centers
  • Conference halls
  • Expo floors

These locations provide the cleanest signal of verified event participation. If a device enters this geofence, you know that the contact was physically present. This matters because a large percentage of buyers attend events without ever scanning a badge or visiting a booth. In short, geofencing will capture attendees who would otherwise be invisible.

Airports serving the event city

For pre- and post-event engagement, you’ll need to expand your circle beyond the venue itself, starting with a key transport hub, the airport:

  • Arrival terminals before the event
  • Departure terminals after the event

Airports are high-signal environments filled with traveling professionals. Geofencing here allows you to introduce messaging before the event begins and reinforce it immediately after it ends, precisely when buyers are reflecting on what they saw.

Event hotels and hotel clusters

For extended exposure windows, think about where attendees will be staying:

  • Official conference hotels
  • Nearby business hotels
  • Walkable hotel clusters

Attendees spend significant downtime at hotels, including between sessions, in the evenings, and before departure. These locations extend your reach beyond the show floor without losing relevance.

Surrounding entertainment and dining districts

For a broader but still relevant reach, think of where attendees may choose to socialize:

  • Restaurants near the venue
  • Bars and networking hotspots
  • Entertainment districts

Event attendees tend to congregate in predictable areas outside official programming. From sponsored happy hours to exclusive networking events, conferences are a pivotal time for attendees to network while exploring the city. Take advantage of this additional reach by geofencing around more informal areas where high concentrations of ICPs are still likely.  

Geofencing for context-driven messaging that resonates

The real power of geofencing isn’t just reach. It’s understanding why a buyer is there and responding with messaging that fits the moment.

Propensity enables it in specific and measurable ways.

1. Detecting physical presence with verified attendance

Propensity enables marketers to create a virtual perimeter around an event location and detect devices that enter it. This provides verified proof of attendance, not assumptions. Many events miss a large portion of buyers who attend but never engage directly. Geofencing fills that gap and turns physical presence into a usable intent signal.

2.  In-moment messaging while buyers are on-site

Once a device enters a geofence, targeted ads can be delivered immediately during sessions, networking breaks, or while walking the show floor. Instead of relying on pre-event hype or post-event follow-ups, geofencing allows you to align messaging with real-time behavior. The result is higher relevance and stronger engagement.

3. Direct attention to where it’s needed

Since you are reaching buyers while they’re actively on-site and in evaluation mode, you can use geofencing to drive audiences to hotspots that matter most:

  • Company booths
  • Sponsored sessions
  • Off-site events
  • Branded content

This allows you to direct traffic toward your physical location, leading to more booth visits, higher session attendance, and increased face time with interested parties and decision-makers.

4. Sequential retargeting based on event entry

Even after the event, contacts who engaged with your geofencing ads can be retargeted with:

  • Product follow-ups
  • Sales enablement content
  • Case studies aligned to event themes

Because geofencing captures real-world presence and Propensity reveals who engages with your ads and visits your site, follow-up is based on verified attendance and demonstrated interest, not anonymous impressions. That focus drives better performance and cleaner pipeline signals.

Events work best when ABM is the strategy and geofencing is the amplifier

Events deliver the most value when they’re treated as intent-generation moments inside a broader ABM motion.

Propensity approaches events holistically:

  • Pre-event: ABM and contextual targeting to warm priority accounts
  • During the event: Geofencing to capture real-world intent
  • Post-event: ABM activation based on verified engagement

Geofencing captures intent signals that traditional ABM can’t see. Then, ABM turns those signals into coordinated sales and marketing action. Together, they bridge the gap between physical presence and digital engagement, turning event participation into measurable pipeline drivers.

Best practices for event geofencing

Based on what we’ve seen across event-driven campaigns, these best practices consistently drive stronger performance:

  • Use smaller, focused radii for venues and hotels
  • Keep the radius under ~15 miles for best performance
  • Avoid minimal radii on desktop and mobile web
  • Pair geofencing with ABM or contextual targeting for stronger results
  • Validate location files before upload
  • Always install the Contact Website Tracker first. This will help you reveal who’s visiting your website from your ads

Make geofencing an invaluable tool for your events strategy

Events are among the strongest real-world intent signals available to B2B marketers. Geofencing allows you to capture that intent at the moment it happens, while ABM turns those signals into coordinated action across sales and marketing.

Together, they connect physical presence to digital engagement and pipeline impact, transforming events from isolated moments into measurable growth drivers.

If you want your events to drive revenue, not just attendance, geofencing should be a foundational part of your go-to-market strategy. Propensity brings the entire motion together, linking real-world behavior, contact-level engagement, and sales activation in one platform.
