Then you ask them follow up questions to make sure they understood your presentation, what they do not understand, what objections they may have, etc. etc. You will close more sales if you are able to get feedback from clients, and Webinars allow you to see their face, to hear their voice to know how they are feeling about you, your presentation, your company and your products and services.

Webinars are a form of online education whose purpose is to pass skills or knowledge across to those who want to learn. They are very useful and highly detailed in their nature and if they are explaining a concept, nothing will be left out of the explanations. Webinars are important in the modern world where putting together pieces of information in order to muster a skill or some knowledge becomes very hard and involving. However, the use of a webinar cuts down the costs and brings lots of benefits, even including making money with webinars.

You’re already a big winner when you’re in front of your webinar audience. Participants were interested enough in your content to register, hold space on their calendar, then show up attentively to your webinar. They have self-qualified themselves as being in the market for the type of product or service you offer, and think you’re the God of SEO (or whatever your schpeel is on).
Don’t feel you need to do a weekly series. A monthly series works just fine, though twice a month is a nice middle ground. And if your schedule is too busy (and let’s be honest, of course it is…), then use a webinar platform like EverWebinar to host an automated webinar. You won’t even need to be there. Heck, you could be kicking it in Belize with a Pina Colada, watching the sales roll in while your webinar is running without you.
In 1996, PlaceWare was founded as a spinoff from Xerox PARC. In November of that year, PlaceWare Auditorium was described in a public talk at Stanford University as allowing "one or more people to give an interactive, online, multimedia presentation via the Web to hundreds or thousands of simultaneous attendees; the presentation can include slides (made in PowerPoint or any GIF-image editor), live annotation on the slide images, real-time polls of the audience, live audio from the presenter and those asking questions, private text and audio conversations in the auditorium's "rows", and other features."[18] PlaceWare Auditorium was formally announced in March 1997 at a price of $150 per simultaneous user.[19]
Depending on the technology being used, participants may speak and listen to audio over standard telephone lines or via computer microphones and speakers. Some products allow for use of a webcam to display participants, while others may require their own proprietary encoding or externally provided encoding of a video feed (for example, from a professional video camera connected via an IEEE 1394 interface) that is displayed in the session.

To attract more participants, you can start from some free webinars for certain times. Once you can get webinars well prepared, run webinars interactively and show the great value of your webinar, more and more participants will be willing to pay for your entire webinars and then it's a good chance to create paid webinars to monetise your expertise.

Web conferencing technologies are not standardized, which has reduced interoperability and transparency and increased platform dependence, security issues, cost and market segmentation. In 2003, the IETF established a working group to establish a standard for web conferencing, called "Centralized Conferencing (xcon)".[6] The planned deliverables of xcon include:

In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers.
