An effective op/ed requires a clear position supported by facts, statistics, or personal experiences. It should be written in a way that feels like the perspective of a real person rather than an institution. Key elements include having a clear thesis, supporting evidence, and a conclusion. Proper use of paragraphs, chronology, and a compelling ending are also important for clarity and persuasiveness. Fact-checking is essential to maintain credibility. When writing an op/ed, writers should consider their intended audience and tone.
