Microdata
An older way of marking up facts, written as attributes on the HTML itself rather than in a separate block. Still understood, but JSON-LD is now the safer choice.

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.
Prompt Library
A saved set of prompts a team reuses so results stay consistent between people. The simplest way to stop everyone reinventing the same instructions badly.
Computer Vision
AI that interprets images and video — reading a document, recognising a product, counting people. The part of AI that has been quietly working in industry for years.
AI Crawler
A bot that reads websites on behalf of an AI company, either to build an index or to answer a live question. They arrive under their own names and obey robots.txt, so you can decide which are welcome.
Prompt Engineering
The craft of writing instructions that get reliable results from an AI — being specific, giving examples, saying what to avoid. Less mysterious than it sounds, and mostly the same skill as briefing a new colleague well.
Applebot-Extended
Apple’s equivalent, governing whether your content feeds Apple Intelligence. Ordinary Applebot, which powers Siri and Spotlight, is controlled separately.
