An event roundup is an opportunity to make an impression beyond an event. The purpose of this post type is to get maximum mileage out of your participation, provide value to your organisation (if they sent you) and provide value to others who either attended the event with you or wanted to. The magic of an event roundup is that you have an opportunity to highlight all the amazing talks, entertainment, and people you encountered. Guess what happens when you mention people in your post and tag them on social media? So long as what you say is positive, they a. love you for it and b. will most likely share the post. So, an event roundup can be a really effective way to get known and build trust.
