Affiliate Marketing is growing in popularity and it is a great way to promote other peoples products or services. In that way you won't have to create products (at least not right from the beginning), you can learn or cut your teeth so to speak by promoting other peoples stuff.
What's great about that is there is no customer service, no product returns, no inventory, no product creation. You are basically learning one huge and incredibly important aspect of internet marketing and that is promotion.
What are you promoting? You are promoting other peoples stuff. Why reinvent genius when someone has already created something wonderful and all they need is your help getting it out there and sold. That sounds like a good deal. They create the product and you help sell it. Not out of the kindness of your heart though.
You do get a commission for selling their stuff. You get a percentage of every unit sold. And with smart marketing, your cost to sell should be significantly less than the revenue you bring in. GREAT! There is your profit. Do it over and over again with good products, then you are in business.
Now you should purchase some if not all of the products you are promoting. Why? Because its great to endorse something you are familiar with and once you are familiar you can give a genuine endorsement of the product. But, that is not the only reason why you should buy it.
Later when you want to sell your own stuff (and perhaps you will), you will know the ins and outs of creating a great product.
That's enough for now. I hope you have benefited from this brief article on Affiliate Marketing.
