Multimodal
An AI that handles more than one kind of input — text and images together, say, or audio and video. It is why you can now photograph a menu and ask an assistant what is in a dish.

Conversational Search
Searching by asking a full question, often as a follow-up to a previous one, the way you would ask a person. It favours pages that answer plainly over pages stuffed with keywords.
Review Schema
Markup for ratings and reviews, including who wrote them. It feeds the star ratings in search results, and gives an assistant something concrete to cite about your reputation.
AI Agent
An AI that does things rather than only answering — browsing a site, filling a form, completing a booking. It is why websites are starting to be judged on whether a machine can use them, not only read them.
Applebot-Extended
Apple’s equivalent, governing whether your content feeds Apple Intelligence. Ordinary Applebot, which powers Siri and Spotlight, is controlled separately.
Model Drift
When a model gets worse over time because the world moved on and it did not. A pricing or demand model trained two years ago quietly stops matching how customers behave now.
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.
