AEO stands for Answer Engine Optimisation. It is the discipline of structuring content so that AI answer engines, including ChatGPT, Google AI Overviews, Perplexity, Copilot, and Claude, can cite it directly in their responses. For thought leaders, AEO is rapidly becoming as important as traditional SEO.
The shift is driven by how B2B buyers now research. With 94% of B2B buyers using AI in purchasing decisions (based on insights from Forrester 2026), the question is no longer whether AI search matters. The question is whether your thought leadership is visible to these systems or invisible.
When a prospect asks ChatGPT "who are the leading experts in employee advocacy," or asks Perplexity "what are the best practices for B2B social selling," the AI draws its answer from content it can parse, attribute, and verify. If your content is not structured for this, you are invisible to a growing share of your market.
