BreadcrumbList Schema
Markup describing where a page sits in the site’s hierarchy. It helps both search engines and assistants understand that a page is a service under a category, not a stray document.
Related terms
AI Readiness
Whether a website can be reached, understood and quoted by AI assistants. It covers crawler access, structured data, clear headings, published contact details and speed — the unglamorous things that decide whether a model will name you.
RAG (Retrieval-Augmented Generation)
A technique where the AI first searches a set of documents, then writes its answer from what it found. It is how assistants quote current information rather than whatever was in their training data.
LLM (Large Language Model)
The kind of AI behind ChatGPT, Claude and Gemini. It is trained on an enormous amount of text and predicts what should come next, which is enough to answer questions, summarise, translate and write.
Zero-Click Search
A search where the person gets their answer on the results page and never visits a website. Common for opening hours, definitions and conversions — and increasingly common for everything else as AI answers grow.
Reinforcement Learning
Training by trial, error and reward rather than by examples. It is how models are tuned to be helpful and to refuse things they should refuse.
sameAs
A structured-data property that links your business to its profiles elsewhere — Facebook, LinkedIn, a directory. It is how a model confirms you exist in more than one place, which makes it far likelier to name you.
