An LLM (large language model) is an AI model trained on vast amounts of text to understand and generate sentences. It is the technology behind ChatGPT, Gemini and Claude.
An LLM learns the relationships between words and sentences from its training text and uses them to answer questions. Many AI services today also search the web in real time on top of what they learned, so the information on the web right now directly affects their answers.
That is why, in marketing, it has become important to organize website structure and content so AI can read them when it learns and searches.
