Digital Twin
A working model of something real — a building, a supply chain — kept in step with it using live data, so changes can be tested before they are made for real.

Training Data
The text, images or code a model learned from. It shapes everything the model knows and every bias it carries, and it is why what your website said two years ago may still be what an assistant repeats.
Prompt
The instruction or question you give an AI. The wording matters more than people expect: the same request phrased two ways can produce noticeably different answers.
Tool Use
An AI reaching outside itself to do something it cannot do alone: run a search, do arithmetic reliably, read a live page. Nearly every useful assistant depends on it.
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.
Semantic Search
Search that works on meaning rather than exact words, so a page can match a query it never literally contains. It is why writing naturally now beats repeating a keyword.
Crawl Budget
The rough limit on how much of your site a crawler will fetch in a visit. Slow pages and endless near-duplicate URLs spend it on nothing, so the pages that matter get visited less often.
