Whatever you call them - member only, membership, subscription, or mentor websites, they all have one thing in common. They are bringing in steady and constant cash flow for their owners, month after month, from a few hundred dollars to tens of thousands of dollars. The array of the topics of these websites is endless.

Some of these paid membership sites provide mentoring or coaching, others publish useful articles or information in a particular field or product. Still others publish the results of tests and studies or product reviews. Some membership sites provide specialized service or act as a meeting place for people with a common interest and then there are those that provide step-by-step instructions for such things as painting or music.

All these sites have one thing in common: to access the website (or the best information on the site) you have to pay for it! Which begs the questionwhy would anybody pay for information on the Internet?

The answer is simple. People buy information that they could probably find for themselves if they looked long enough and hard enough, because they want to save time or because they think the information will be better or more specialized or because the information just isn't available to them unless they pay for it.

Just a few short years ago it was almost unheard of to charge for access to a website and almost no one was doing it. Today, however, it is the norm and not the exception. Actually we have Internet dating sites to thank for this huge money making opportunity.

The Internet dating industry began with free membership sites that were mostly populated by nerds, weirdoes and perverts. It was quickly discovered that ordinary people would gladly pay to have access to lists where the posters had been screened even just a little. Now people actually expect to pay for access to valuable information.
