*Methodology* · *Content Strategy*

## Definition

A topical gap is a question, subtopic, or related concept within a brand's claimed domain of expertise that is not addressed by any existing piece of the brand's content — creating a gap in topical coverage that competitors or other sources fill by default.

## Why It Matters for AI Search

Topical gaps are missed citation opportunities. Every question in a brand's domain that goes unanswered by the brand's content is a question that gets answered by a competitor's content — building the competitor's topical authority at the brand's expense. Identifying and closing topical gaps is the systematic version of content strategy: not publishing what seems interesting, but publishing what is missing from the brand's coverage of its domain.
