Many marketers have created or acquired products that they thought would sell well and, in their enthusiasm, set up everything from sales letters to websites to getting traffic. However, a lot of these marketers have forgotten the single most important factor that will affect their product sales, the "sellability" of the product.

When you begin creating products or buying rights to a certain product to sell, the most important factor you must take into account is the demand of the product. Do people want your product? It is simply stupid to waste a month's time preparing a product, setting up the website and required sales techniques only to find that people do not even flick an eyebrow at your product!

Your final goal is to deliver the product to your customer and collect his or her money. In order to do this, you must make sure your customer wants to buy your product in the first place. How do you find out if they want your product? Simple. Just ask! Ask in forums related to your niche. Hold a survey or public poll. The Internet is a flat playing field, and you have the power to reach just about anyone in the world who has an Internet connection.

Let's say you have this brilliant idea on creating a step-by-step instruction on how to cook Malaysian food. First, you must find out if anyone is interested (or even heard of) Malaysian food. To do this, go to a food-related forum and ask tactfully if anyone would be interested in learning Malaysian cuisine. Do not ask blatantly whether anyone would like to buy an ebook with instructions on how to cook Malaysian food, or you might be in danger of being accused of spamming.

On the other hand, you can give out a few samples of your Malaysian recipes to test the waters and see how the forum members react to them. If they show enthusiasm for learning more, then you definitely have a market in this. If they show no interest, then it is time to look for a new idea to market. You save time in the long run because you don't have to find out the low demand for your product the hard way.

If your idea is welcomed by the forum members you surveyed, you can go ahead and compile your extensive ebook on cooking Malaysian food because there is interest in the information you possess. Where there is interest, you can easily build up desire for your product, and with desire (plus good marketing), your purchases will arrive naturally!
