I am quite busy and may not have time for now to explain everything but will answer questions later when I have time. For now, I am not going to share my site but will share others who I consider to be my competitors.
I provide information for those students in the USA who are looking for colleges that offer online degree programs. In doing this, I will go into the details of each degree course, career objectives, jobs prospects etc.
The trick is to make sure that I rank well in google. Once you have started to rank, you contact some f those organizations that would allow you to have an affiliate arrangement. Once they agree, you are okay and you have a business. The biggest risk here is that after all the hard work, google may time to time change how they rank sites and you could get a thorough beating which could wipe almost all of your income.
This area is very very competitive and is very difficult to rank but if you do, the income is very good and can really change your life.
Before google penguin update, this site
http://www.distance-learning-college-guide.com/ was a close competitor. That site was also affected by penguin. But large sites like this
http://www.elearners.com/ an this
http://www.guidetoonlineschools.com/ gets money that you would not believe in my estimation.
You can decide to try other areas that are not competitive. Let me give you a link that could help you with other ideas and also see what kind of sites people have. The page is about a site builder showing successful sites that have been done using their site builder. So do not get confused but take time and go through the whole page.
