CT: Blogging, social media, forums—these are just some of the many ways to promote your brand or sell your product online. But if you’re more of a public speaker and want to share your ideas upfront with your audience, you can set up and host a webinar.
A webinar or a web-based seminar is a great way to build your brand and/or promote a product you want to sell online. Unfortunately, webinar software are quite expensive with a steep learning curve to get through. Popular software like GoToWebinar, AnyMeeting, and ClickWebinar charge $30-$99/month based on the number of attendees and features like recordings, ads-free experience, and live support.
