The document provides guidance on developing a social media marketing strategy for trade shows. It recommends starting with small, experimental steps like creating profiles and monitoring discussions to understand the landscape. The key is to listen first, then engage by offering value to the community. The message should be tailored to each platform and target different professional groups. ROI comes from many small interactions over time rather than big campaigns. Risks include lack of control and permanent comments, so content needs oversight. Success relies on an ongoing plan with dedicated resources.
