Your trade show presentation should be followed up effectively, promptly, and strategically in order to maintain contact with your audience, nurture your leads, and convert them into customers. To do this, you need to collect contact information from your audience, such as email addresses, phone numbers, or social media handles; you can use a sign-up sheet, a business card drop, a QR code, or a lead capture app. Additionally, you should send follow-up messages within 24 hours of your presentation; thank them for attending and remind them of your main message and brand identity. Don't forget to provide additional resources such as a link to your presentation slides, a blog post, or a white paper. Furthermore, offer incentives or value-added services to entice your audience to take the next step. Include a clear and urgent call to action and a deadline to create a sense of urgency and scarcity. Lastly, track and measure your results such as the number of leads, conversions, and sales generated by your presentation; use this data to evaluate your performance and optimize future presentations. Public speaking is an effective way to promote your brand at trade shows; by following these tips you can increase your visibility, credibility, and profitability.
