So how exactly do you make it happen? First you need to decide whether you want to market your product by yourself or if you want to use the services of a third party. This is a huge factor in deciding how to market your product and hence you need to think about it hard.
An example of a third party would be Clickbank. This is a place where others are given the opportunity to promote your product for you. They create banners and place them on websites so that others will have the opportunity to click on those banners and see your product. If they like it, then they will be able to make a purchase, meaning that you have sold your product, and the person who helped your promote it will also get a share. This could be seen as a one stop money making machine because it is easy to use and you barely have to do any work.
If you would rather promote your product by yourself then it will be necessary to create a website. In doing so you will have to make sure that your site is keyword optimized. Optimizing for keywords will require that you use Google AdWords to find the most used keywords associated with the product you are trying to sell, and then you will need to incorporate those into your website. This will seem very tedious at first, but once you get it set up you should have no problem making sales so long as your product is something that people will want.
There is no one particular ''One stop money making machine'', but with a little bit of work you can start making money with minimal effort. Whether you market the product yourself or you get a third party site to market it for you there should be no issue with cash flow. Just ensure that you go with the option that best suits your wants, needs, and the time you have available.
Just keep in mind that you will have to market to a lot of different people, and some of those people might not like what you have to sell. Don't be discouraged if you don't make many sales at first, because all companies had a rough start, excluding Microsoft of course, because when they came out with their product there was nothing else like it, and even though there was that fact, everyone still needed it. Good luck with your marketing campaign! Hopefully you will be able to build up a lucrative business that is very successful.
