Constant Content

Is it frowned upon to rewrite your sold articles? I don't mean copying the language, but rather writing another article containing the same information.

I would steer clear from that. There are many repeat buyers here and if they find that they've bought an article thinking that what they're getting is unique, only to find that the same thing in different words is being sold, they'll start leaving this site.

I guess that in such cases, you should inform your clients of such a varient of work, of course, providing 100% of originality of a new piece of writing.

I often use similar themes but try to put a fresh twist on it. Some topics can't help but be a little repetitive such as budgeting, real estate, home staging. Some of those buyers would expect some conformity.

So my answer is "it depends".
