The best way to evaluate your topic is to conduct a live Q&A session. The audience gives their opinion about the topic you have selected and asks various related questions that will help you to create the perfect strategy for your webinar.
You can also market affiliate products during your webinar and earn money by each sale made during the webinar. During the webinar, a presenter speaks on the decided topic and can give the sales page of the affiliate at the end.
Content is the reason people register and attend your webinar, so without great content, either won�t get people to show up or you won�t get them to come back. Carefully select your topic/title/speaker based on your target audience�s interests and needs, as it relates to what your firm does. Generally speaking, webinars are intended to be educational�not �salesy��so be sure that you create content that your audience finds helpful and valuable.
Send reminder mails to registrants in order to remind them of the webinar. It will allow them to schedule their work accordingly and would help you get the maximum number of people for your webinar.
