AI SEO Glossary

Share of Answer is the metric that measures what percentage of the total answer content generated by AI platforms for a defined set of queries includes your brand in a meaningful way. It differs slightly from Share of Voice in that it focuses on the proportion of total answer content, not just the number of prompts where you appear. A brand with high Share of Answer is not just appearing frequently but is occupying significant portions of AI-generated responses, being cited as a primary source, discussed in depth, or recommended prominently rather than mentioned in passing.

Increasing Share of Answer requires moving from surface-level brand mentions to becoming a primary cited source in generated responses. This means building deeper topical authority so AI systems see you as the definitive source on relevant topics, creating content with the specificity and depth that AI systems use when elaborating on a topic, earning citations from other high-authority sources that reinforce your credibility, and ensuring your content directly addresses the full range of questions users ask in your category. Brands that appear as one of several passing mentions need to become the source that AI relies on to explain the topic comprehensively.

Why it matters: Share of Answer is a quality metric on top of Share of Voice. Being mentioned is good. Being the source the AI builds its answer around is significantly better.
