Distance learning courses are very popular and a natural way for you to market your other products and services.
1. It gets your name out.
Listing your courses on www.teleclass.com or www.blackboard.com will put your name in front of many new people.
2. It helps establish your expertise.
If you're good at what you do, it's natural you would start teaching it.
3. It allows you to reach different markets for potential clients.
The people who take teleclasses are different from people who take computer courses, yet both may be interested in your services. Some may also just be looking around, and may click through to your website and get interested in something else entirely!
4. You can use them to naturally promote your other products and services.
How often has someone said to you, "Oh. I didn't know you do that too." In my Emotional Intelligence (EQ) course, it's quite natural for me to mention assessments student should take (I'm licensed to sell EQ-Map assessment), and opportunity for other courses I offer (on different competencies, such as resilience, intuition and creativity), and tapes and products I sell related to EQ. Once you know EQ, why not buy one of my mugs that says "EQ is better than IQ!" to help spread word?
5. There are affiliate opportunities.
My students are interested in learning all they can. I'm an affiliate for amazon.com. I recommend books they should read and have link within course. When they buy through my link, I make money. EQ means working out right brain, so I can also recommend "dummies" course in music appreciation, with links provided, and my art appreciation course.
6. It closes a loop.
There are numerous research studies showing that EQ is best learned through interaction, such as coaching, so it's a natural for serious student to then sign up for EQ coaching to complete and round out their learning experience.
7. Open loop!
A good distance learning course provides resources for lots of other learning opportunties, some of which will be yours! I also pair with another coach who offers services I don't want to provide. Once they go to her to learn XYZ, her courses refer them back to me, for special things I offer. We both build our practices that way, and sell more useful products.
