How affiliates can take advantage of webinar marketing
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.
