Semantic Search
Search that works on meaning rather than exact words, so a page can match a query it never literally contains. It is why writing naturally now beats repeating a keyword.

Markup for step-by-step instructions, labelling each step in order. Useful for anything procedural, and easy for an assistant to reproduce accurately.

How recently a page was published or genuinely updated. It matters most for things that change — prices, availability, guidance — and matters little for things that do not.

When a system produces unfair results because its training data reflected an unfair world. It matters commercially as well as ethically: a biased model makes confidently wrong decisions about real people.
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.
