Vector Search
Searching by meaning rather than by matching words. A page that never uses the phrase somebody typed can still be the best answer, and vector search is what finds it.

Watermarking
Marking AI-generated content so it can be identified later, often invisibly. Part of the same effort as provenance, and equally early.
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.
Content Provenance
A record of where a piece of content came from and how it was made, sometimes attached to the file itself. Emerging as a way to tell an original photograph from a generated one.
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.
Deep Learning
Machine learning using neural networks with many layers. The depth is what lets a system learn complicated things — recognising a face, translating a sentence — without anyone specifying how.
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.
