I started doing teleseminars in 2006. By 2007 my business model included free weekly teleseminars, as well as courses and other training. I received what I believe is the very best in teleseminar training, and I still use these techniques today. In 2008 everything shifted, and people began to ask me to do webinars so that they could see me teaching them the technology necessary to build a profitable online business.
Webinars are now a regular part of my trainings. This is an example of what happens when your market changes and you must change with it. Many of those who teach online have not changed over, and their students often become my students because they want to see blog features, article marketing, social networking, and affiliate marketing instead of only hearing about these things.
Take a look at what you are doing online. Are you staying current with the demands of your target audience? if not, what do you need to change?
