Public Domain products allow Internet marketers great flexibility. They can be used to profit from mini-sites by selling info products, create content for membership sites, or even for use in niche sites. Let's look at how you can profit with each type of site:

Instant Information Products

The public domain has the power to provide you with instant products. Pick a market, evaluate it's profitability, and use a public domain work to immediately launch your info-product business. A stunning example of this is how you can use courses and books directly from the early 20th century to re-package and sell instantly online. The value of information in such books such as 'The Secret of Wealth' by Franklyn Hobbs is timeless and easily worth your time and investment and there are many such books available on the public domain.

Membership Websites

If you are looking to start a membership website that provides quality information on a niche topic but do not want to invest too much in time and work (by writing the content yourself or paying someone to write it), you can use public domain information to get you started. Since start up membership sites traditionally need 2 to 3 months of information before offering monthly-fee subscriptions, the work required is quite a lot and if you can find public domain works to supplement your content, you may have hit a potential goldmine.

Create Multiple Delivery Streams

This is a business maxim that Internet business gurus swear by. We have all heard about the power of having multiple income streams, but that's only half of the story. If you are delivering products through just one medium (i.e. through info-products or just selling services), you aren't realizing the maximum potential of the income-generating abilities of your business.

As flowery as that sounds, consider the impact of using an audio-course, memberships, info-products and AdSense income on a single business venture instead of using just AdSense on an 'informational' website. While such a business venture requires a lot more work than just 'set and forget', you can still manage a great degree of automation. The key is to maximize your business potential by using every possible method to profit from your products.

In all, the public domain can add another income stream from any type of site or can be used as a product alone on a single mini-site.
