A zero-click search is a search session in which the person does not visit an external website. The answer may appear directly in the results, the person may refine the query, or the search may end without a satisfactory answer.

SERP stands for search engine results page: the page shown after a search. It can contain organic results, advertisements, maps, images, videos, featured answers, and AI-generated features, so a ranking number alone does not describe what someone sees.

SEO, AEO, and GEO are overlapping labels for work that helps information remain accessible, understandable, useful, and verifiable across conventional and AI-assisted search. The interfaces and measurement differ, but there is no universal AI-only checklist or guarantee of inclusion.

AI search visibility describes whether and how an organisation appears in answers produced by AI products that search or retrieve information from the web. It must be measured under stated conditions because answers can change by product, prompt, date, location, and account state.

Social listening is the structured review of public conversations to understand how people describe a subject, which questions recur, and where expectations are changing. It is research, not simply counting mentions or accepting an automated sentiment score.

Social proof is evidence that other people or organisations have trusted, used, selected, or recommended a company. It can help a reader assess an unfamiliar claim, but only when the source, relationship, and context are clear.

Social search is the use of social platforms to find people, organisations, products, recommendations, expertise, and answers. Discovery may begin with a search box, recommendation, hashtag, comment, profile, or shared post.

Search intent is the task a person is trying to complete when they search. The same subject can signal a need to learn, compare, verify, navigate, or act, and the right page depends on that task.
