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.

AEO (Answer Engine Optimization)
Answer Engine Optimization is the work of becoming the source that answers a question rather than one of ten links offered. It matters because search increasingly replies with a written answer, and only one or two businesses get named inside it.
Rich Result
A search listing with something extra — stars, prices, an image, an FAQ dropdown. Rich results come from structured data, and they take up more of the screen than a plain blue link.
Crawl Budget
The rough limit on how much of your site a crawler will fetch in a visit. Slow pages and endless near-duplicate URLs spend it on nothing, so the pages that matter get visited less often.
Grounding
Giving an AI real source material to answer from, instead of letting it rely on memory. A grounded answer can be checked and cited; an ungrounded one is where hallucinations come from.
Organization Schema
Structured data describing the business itself: name, logo, address, contact details, social profiles. The single most useful markup for being recognised, and the one most small sites are missing.
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.
