How do I only target people at an event or convention center?

For event-based campaigns with short durations and intense bid competition, we strongly recommend using Geotargeting to create a radial fence around the event or convention center. This approach ensures optimal coverage and reach. Adjusting the CPM (Cost Per Thousand Impressions) to a higher range is essential to improve bid success rates. We suggest setting the CPM at $8 for mobile banners and $15 for mobile videos. Additionally, enabling Delivery Optimization will help maximize the number of impressions served.

Another option to consider is On Lot targeting, which focuses on delivering ads within the Blueprinted polygon fence of the convention center. However, this method may have limited scale, as users with less precise location signals could be filtered out. In contrast, the radial fence in Geotargeting is more inclusive, reaching a broader audience. Convention centers with high activity levels may also experience GPS accuracy issues, making the radial fence a more reliable choice. Moreover, the circular shape of the radial fence offers wider coverage than a square.

To further enhance your campaign’s effectiveness, we recommend using the Build Audience function to create a retargeting segment. This enables you to set up a dedicated ad group with Audience Targeting, allowing you to continue serving ads to users even after they have left the convention center. This strategy extends your campaign’s reach and impact.
