1.Look for a good market of readers
With a lot of magazines available, it will be hard to find a target of readers that have not been addressed yet. And if ever, you find one, chances are the magazine for that niche was already created years ago, only that it did not work. But hey, nobody said that you too will not succeed. When you look for target readers do not just stop on the demographics. Research on the articles that they want to see in magazines. Zero in on the products that they feel they will be able to use. You can even make a survey on the people that they want to be featured or the people in the field that they look up to.
2. Look for famous columnists
One secret to promoting your magazine and thus ensuring the success of the venture is to look for famous people in the industry. Their names are often enough to pull some readers into buying your magazine. They will also be able to help in marketing your magazine through word of mouth and industry news. Once everybody finds out that a recognized expert in the field is writing for a magazine, they will buy the mag, even just out of curiosity. It will be a nice start.
Even with the biggest name in the field in your magazine, without good content, your magazine will go nowhere. The number one selling point of any magazine are the articles that you will find within. Remember that having big names is just the introduction. What you need is to sustain the interest with features that they can relate to and use. To do this, you also need to hire good writers in the field. Pick one who does not only write well but one who has interests in the field.
