A good text does not contain any orthographic, grammatical or syntactic errors, is reader-friendly and well-researched in terms of its contents. Furthermore, it approaches the target group in a convincing way. To achieve that, it is often necessary to apply the two-man rule (also referred to as 'four-eye principle'), especially when your texts are to be published in many copies. By applying this rule, the text is checked by an independent linguist who can spot mistakes that went unnoticed.
