A helpful way to write to your target audience. One really useful way to keep your target audience in mind when writing is to create a persona who represents your target audience. Give this person a name and find a picture of what you think this person looks like. Post this photo and description near your computer as you write your salesletter. As you write imagine that you are writing/talking to this person. I find that doing this really helps me to connect to my prospect and makes the copy much more real and personal.
Writing an article without any research or insider knowledge of the subject matter is of no use. Even if you can bring a person to your page by using some creative headline, you cannot make them read your article or link into the website that you want to promote. There is no trick or easy way to article writing when it comes to creating original content - research is the only solution.
