What is AI Shelf Share?
AI Shelf Share is the proportion of citations that your brand or content receives when AI answer engines — ChatGPT, Perplexity, Google AI Overviews — respond to queries in a given topic or category.
The term is borrowed from retail, where "share of shelf" describes the percentage of physical shelf space occupied by a brand's products.
Why does it matter?
As AI search grows, users increasingly encounter brands inside AI-generated answers rather than through a click on a search result. Traditional SEO metrics based on click-through rates cannot capture this exposure. AI Shelf Share fills that gap.
How is it measured?
- Define a target set of keywords and topic areas.
- Query AI answer engines repeatedly on those topics.
- Count how many responses cite your brand or content.
- Calculate share relative to competitor citations.
