LLM (Large Language Model)
A large language model (LLM) is the kind of AI behind tools like ChatGPT, Claude, Gemini, and Perplexity. Trained on vast amounts of text, it generates human-like answers by predicting what comes next — which is why it can summarize, explain, and respond in natural language.
Why it matters
LLMs increasingly sit between your content and your customer. When someone asks an assistant a question in your field, an LLM composes the answer — sometimes citing sources, sometimes not. Understanding that your content can inform (or be left out of) those answers is the foundation of GEO.
A key limit
An LLM doesn’t “know” facts the way a database does; it generates plausible text, which is why it can be confidently wrong and why being a clear, citable source matters.
WebSignalytics connects to your Google Analytics and emails a plain-language report every Monday — what changed, why it matters, and what to do next, including whether AI search is citing you. No dashboards, no logging in.
