Contextualise
Make it relatable
Try to address or include things everyone can relate to or has an opinion about. This will make conversation between online and offline easier.
Find Your Audience
Connecting hybrid/online events to existing (offline) events can increase your chance of a bigger turn-out. An additional plus is that connecting hybrid/online events to pre-existing offline events can attract an audience that is already likely in an outgoing mood and interested in being extroverted.
Connect
If you can offer your audience something they are very interested in and actively involved with they will be more interested in interaction and participation. An extreme niche topic can be very suitable for an online event, as long as you find the audience it connects with.
