Supervised Learning
Training a model on examples that are already labelled with the right answer. It is the most common approach when you know exactly what you want the system to produce.

GPTBot
OpenAI’s crawler for building its index. Blocking it in robots.txt keeps your content out of that index — and out of the answers built from it.
Hallucination
When an AI states something false with complete confidence — an invented price, a policy you never had, a product you do not sell. The usual cause is that the correct fact was not available anywhere it could read.
Speech Recognition
Turning spoken words into text. It underpins voice search, dictation and call transcription, and it now handles accents and background noise far better than it used to.
NLP (Natural Language Processing)
The field concerned with computers handling human language: understanding it, generating it, translating it. Everything from spam filters to chat assistants sits somewhere in it.
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.
Agentic Browsing
An AI navigating a website on somebody’s behalf: finding the price, checking availability, sometimes buying. Sites that rely on hover menus and unlabelled buttons are hard for an agent to use.
