Query augmentation is a process that involves the expansion and refinement of a user’s initial query by adding modifiers or related terms. Its goal is to improve search accuracy and relevance by including additional terms or entities related to the initial query. Systems achieve this by adding attributes related to identified entities (e.g., adding “age” or “biography” for a person), leading to more refined and relevant search results. Marketers can research query augmentations by analyzing SERP suggestions, extracting key entities, and mapping them to attributes and variables.
