When you set up a campaign in Boost Express, one of the most important choices is selecting audiences. Audiences are predefined groups of event participants created by the organizer. Instead of uploading your own data or configuring targeting rules, you simply select from these ready-to-use groups.
This system makes targeting more accurate and saves you time when launching campaigns.
Understanding Audiences
Audiences represent groups of people who are part of the event. In practice, this means participants who attend sessions, visit the event website, or engage with the organizer in other ways.
These are the people most likely to interact with sponsor messages because they are already connected to the event context and show interest in its themes. By using audiences, campaigns focus on participants who are relevant and active, rather than a broad or generic external group.
Audiences are built by organizers using:
- Website data – collected data from the event website, including page visits, form submissions, and button clicks
- Uploaded contact lists – attendee information and company details
Sponsors do not upload this data themselves. They only work with the ready-made audiences prepared for targeting.
Choosing Audiences
When editing a campaign, you browse audiences grouped into folders, with the structure depending on how the organizer sets it up.
You can select one or multiple audiences for a campaign. Choosing several audiences increases your reach, since your ads will be shown to participants from any of the selected groups.
Audience Expansion
Along with selecting audiences, you can use Enable Audience Expansion. This option allows Boost Express to include more people who share similar attributes to your chosen audience, such as job titles, companies, or skills.
It helps increase reach and works best if your goal is broad exposure rather than narrow focus.
How Audiences Help You
- Relevance – targeting based on the event context, reaching participants most likely to be interested.
- Efficiency – time savings from predefined groups without handling raw data.
- Flexibility – ability to combine audiences to broaden reach or focus on a specific group.
Best Practices for Audience Selection
- Start broad, then refine – If this is your first campaign at an event, it can be useful to begin with broader audiences to reach a wider share of participants and see how the campaign performs overall. Once you are more familiar with the event context, you can experiment with narrower or more specific audiences.
- Avoid over-selection – Selecting too many unrelated audiences can weaken your message and make performance harder to analyze.
- Test combinations – Running separate campaigns for different audience groups helps you compare which ones bring the best results.
Privacy and Data Handling

- Sponsors never see individual-level data or raw contact information.
- All targeting is based on aggregated audiences prepared by the organizer.
- Boost Express is GDPR compliant, ensuring that all participant data is handled securely and in line with international privacy standards.
