Start promoting your webinar: If everything above laos country code and mobile number is already defined, now set a date and time, and start a campaign to attract interested parties. You can include media such as mailings, social media campaigns, forms, images for WhatsApp, stories, among others.
During the webinar
Prepare for your webinar an hour in advance: When the day arrives, check all the technical aspects: your microphone, that the platform is working correctly, your internet connection and support material. It will also be important for you to see the permissions you have (as well as those of the other speakers) on the webinar platform, that is, that you appear as a speaker and can manage tools such as questions and answers, giving the floor, etc.

Appoint a Community Manager (CM): It doesn't necessarily have to be a Community Manager, but it does have to be someone who can act as one. Why? You'll probably get a lot of questions from attendees during the webinar, and since you or the presenter will be busy talking about the topic, this CM will help you organize them and pass on the most important ones to the Q&A session.
Stick to your script or outline: Stick to the times you have designated, don't go over the allotted time and don't try to talk about a topic that wasn't in the script. If during the conference, something related to what you are saying comes to mind, you can mention it briefly and save it to create a new webinar. Again, reduce improvisation, the more organized and to the point, the better.
