Include Q&A sessions and other discussions as a perk for your membership sites. You can also organize paid Q&A sessions for your audiences with you or other experts associated with you.
People attend webinars for the quality content they will be receiving from it. Don�t dedicate your entire webinar to promoting your product and services, rather provide your audience with top quality content along with a relevant and targeted sales pitch at the end of the webinar.
How to get traffic towards your webinar
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.
