The profit margin is very good. Your time and overhead needs to be covered, but on the other hand, you don't need to buy materials to make it, nor do you need to sit and stand for hours because most of the work you will do includes custom projects that can be prepaid and/or will be paid shortly after creation. Your product is time-sensitive, meaning there is always a sell-by date for your work. Sometimes the expiration date is quick, like for news, and sometimes the expiration date is longer, like for topics about love or weight loss. The longest lasting ones are called evergreen articles, but this is a misconception because no content is ever able to stand the test of time unless it is fiction. Expiring your content is a downside, but other than expiration there is very little depreciation on your product. It does not age, collect dust, or need cleaning, and it is very difficult to steal if kept offline until needed.
