TL;DR

LLM SEO — also called GEO (Generative Engine Optimization) or AEO (Answer Engine Optimization) — is the practice of earning citations inside ChatGPT, Perplexity, Google AI Overviews, Claude, and other AI-generated responses. The data behind its urgency is now unambiguous: only 11% of domains are cited by both ChatGPT and Perplexity, making cross-platform monitoring non-negotiable. Reddit alone accounts for 46.7% of Perplexity's top citations, 21% of Google AI Overview sources, and 11.3% of ChatGPT references. 80% of LLM citations don't rank anywhere in Google's top 100 for the same query. And brands cited inside AI Overviews earn 35% more organic clicks and 91% more paid clicks than non-cited competitors. The right LLM SEO tool stack covers three layers: source-level intelligence, brand visibility monitoring, and entity management. This guide covers the tools that deliver each layer — starting with the platform that addresses all three: Dageno AI.

Why LLM SEO Is Now a Distinct Discipline from Traditional SEO

The evidence for treating LLM SEO as its own discipline — not a feature of traditional SEO — comes from the citation data itself. According to AIVO's March 2026 GEO data analysis, 80% of LLM citations do not rank in Google's top 100 for the original query. Only 38% of AI Overview citations now come from top-10 organic results. Google's shift to Gemini 3 fundamentally changed the relationship between traditional rankings and AI citation probability.

The competitive fragmentation makes cross-platform strategy essential. According to The Digital Bloom's 2025 AI Visibility Report, synthesizing 680 million citations, only 11% of domains are cited by both ChatGPT and Perplexity. These are not the same optimization problem, and tools that track only one platform miss most of the competitive landscape.

The LLM SEO Source Layer: What Actually Gets Cited

Wikipedia serves as a foundational authority layer, and content structure remains crucial for LLM citations.
