Answer Engine Optimization (AEO)
Definition
The discipline of structuring content so it appears as a cited, direct answer within AI-generated responses from platforms such as ChatGPT, Perplexity, Google AI Overviews, and similar systems. AEO targets the retrieval layer of AI systems rather than traditional keyword ranking positions.
Context
According to a Peec AI analysis of 30 million AI citations, Reddit was the #1 cited domain across ChatGPT, Gemini, Perplexity, and Google AI Overviews. Perplexity alone pulled 24% of its citations from Reddit in January 2026. However, citation patterns vary by platform and category — Google Gemini cites Reddit far less frequently than Perplexity, making platform-specific AEO strategy important rather than treating all AI systems as identical.
Relevance to Reddit
Reddit is among the most-cited domains across major AI platforms, making genuine Reddit participation a direct AEO lever. Brands that contribute content directly answering common buyer questions in relevant communities increase the probability that AI systems cite those threads when users ask related questions. AEO and organic Reddit strategy are now closely intertwined.
