I hereby present to you 25 Profitable Business Model:

1. Author A Publication – You can write your own publication about any topic. You should do research first so as to fill a want in an audience or market with money to spend. Otherwise you can waste a lot of time. You can sell it yourself and keep all the profits or deal through other distributors and share the profit.

2. Co-Author A Publication – You can write a publication along with another author. You could sell it separately or both sell it and split the profits. You could also have multiple co-authors.

3. Compile A Publication – You could allow other authors and experts to write the publication for you in exchange for free publicity or other incentives. You would simply contact the authors and experts you want and ask them to donate some content.

4. Start An Affiliate Program For The Publication – You could allow other people to sell your publication for a percentage of the profits. You could eventually have literally thousands of people promoting your product with very little work on your part and no out-of-pocket expenses.

5. Sell The Reprint Rights To The Publication – You can allow others to sell the publication for 100% of the profits. You could include ads for other products that you’re selling for a back-end, which means the sale of your other items through the ads.

6. Sell The Master Reprint Rights To The Publication – You could allow other people to sell the publication and the reprint rights to the publication. You could still include ads of your other products.

7. Give Away The Publication – You could allow people to give away the publication to their prospects, customers, visitors, subscribers, etc. Of course, ads to your other products would be included in it. This will easily spread you advertising and potential sales all over the place

8. Give Away A Branded Copy Of The Publication. You could allow other people to give away the publication and allow them place their own ads it. This gives them an extra incentive to give it away to their prospects, customers, visitors, subscribers, etc.

9. Sell A Branded Copy Of Your Publication – You could allow other people to give away the publication as their own and charge them to place their ads in it.

10. Start A MLM/Multi-Tier Affiliate Program For The Publication – You could allow other people to sell your publication for a percentage of the profits. They can also make commission from people they recruit. You could eventually have literally thousands of people promoting your product with very little work on your part.
