Organic Growth Knowledge Base
Organic discovery in 2026 spans Google, ChatGPT, Perplexity, Google AI Overviews, and Bing. Pages ranking first on Google are 3.5 times more likely to be cited by ChatGPT than pages outside the top 20. LLM-driven sessions grew approximately 527% between 2024 and 2026. Brand search volume is the single strongest predictor of LLM citations (0.334 correlation). GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) extend SEO; they do not replace it.

This knowledge base breaks down what the best available research says about organic growth in 2026, where the evidence is strong, where it's thin, and what to actually do with it.
