Some other things to keep in mind are giving proof of what you say is fact. For example if you can quote a study or survey that has been done to back up your claim, or income testimonials, just like if you recently buy Twitter followers. Include their URL link and/or address. Quoting statistics is not really very effective unless you provide the source of your statistics or claims. At any rate they can help you to create an interesting article, either way. You can pretend you are writing to a friend, for one thing and that will take away much of the stiltedness (unnatural formality) that seems to be prevalent in a lot of business writing.
None of this is to say at all that you should focus your writing on selling unless you are specifically creating a sales page. For the purposes of ‘content’ you always want to keep it purely informational, conversational and interesting — for example to describe some condition or substance factually, and then discreetly at the end you might add a paragraph describing how your product or service fits the bill and include your link. An example here would be an article about some human condition, and then you provide the remedy or solution.
This can apply to home business opportunities, for example the condition being ‘paycheck doesn’t go far enough anymore’ or ‘hate your job?’; bottom line is starting a home business can be the solution to either one or both conditions! Work at home and sign your own paychecks.
