Dual audience of content is an approach in which a text is deliberately written for two readers at once: a person who needs context, a narrative and a reason to keep reading, and a machine that needs unambiguous statements that can be extracted and cited. It is not about two different texts, nor about hidden blocks for robots, which is a practice that borders on the rules. It is about structure. The proven solution is answer first, elaboration afterwards: in the first paragraph, a factual summary with figures and conditions, followed by explanation, examples and context for the human reader. Formulate headings as questions or precise labels, place key facts in stand-alone sentences, and use a table wherever parameters are involved. The text thus remains readable while still allowing a passage to be extracted that stands on its own.
