The process of engaging your target audience has evolved very much with the advancement of technology and methods of promoting. Webinars are one of the most effective ways of engaging a target audience.
When you have consistent attendance for your webinars, sponsored ads and announcements can help you make money by recruiting sponsors for webinars to help cover costs.
It is really difficult to get an audience to be a part of your webinar. You always need to look for a topic from your niche that is trending to be able to capture the attention of a large audience. Do some research and look for customer problems. Be relevant and informative with your webinar topic to encourage more people to attend your webinar.
