Your first few webinars about the topic you are discussing and the product you are launching should be live in order to create the kind of 'buzz' people who attend webinars have come to expect. Once you have several recordings, and/or have fine-tuned the presentation and the offer, you can create a permanent, evergreen, automated webinar that will keep selling for you regularly. Upload your recording and set a calendar of replay, and watch the cash keep flowing in.
