HowTo Schema
Markup for step-by-step instructions, labelling each step in order. Useful for anything procedural, and easy for an assistant to reproduce accurately.
Related terms
Product Schema
Markup for an item you sell: name, price, currency, availability, condition. Without it an assistant reading your shop has to guess the price from the page, and sometimes guesses wrong.
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.
Speakable Schema
Markup identifying the parts of a page suitable to be read aloud by a voice assistant. Narrow in application, but it removes the guesswork about which sentence answers the question.
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.
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.
Answer Engine
An answer engine replies to a question with a written answer instead of a list of links. ChatGPT, Perplexity and Google’s AI Overviews are all answer engines. The old question was “do we rank?”; the new one is “are we the answer?”
