This competitive intelligence doesn't mean copying what others do well. It means understanding the bar you need to meet or exceed to compete for AI citations in your niche. If competing content provides basic overviews, offering in-depth analysis gives you an advantage. If competitors focus on theory, adding practical examples and case studies differentiates you. If everyone covers similar points, finding unique angles or addressing overlooked aspects of the topic creates competitive advantage.
