Firstly there are several tools available on the internet which are there to be used to do market research. The two most effective ones are Google keyword tool and yahoo (overture) keyword tool. You can use these tools by trying different keywords related to different markets and seeing how much they are searched in a month. This shows the demand for a market. With Google keyword tool you can also see how much people are paying for advertising that keyword per click or how much they are bidding for a keyword. This type of information is priceless in terms of firstly finding markets with untapped opportunities and also for finding out if it is a profitable market how to generate traffic whether through Ad words or mainly the free traffic generating tools such as article marketing or blogging. If there is very high bids for the keywords it might cut into your profits by using ad words as a traffic generator. This type of information helps you find out worthwhile investments

The most important thing is to practice this skill over and over again. I know we all know this from childhood, the only sure way to become an expert in anything is through practice, through repetition. Write a daily plan to exercise the profitable market selection everyday. After a while it becomes second nature. When you hone this skill you reduce so much potential waste of time and money by minimizing risk. It's less risky to spend your time and money promoting a website for the market that is sure gold than for one that does not show that much potential. The way to know that difference is by knowing to effectively choose profitable markets. There is so much to this skill and I believe if you want to be successful in the internet marketing industry this is one skill you need to become an expert in.
