What Is Your Brand's Share of Answer?

Share of Answer (SoA) is a brand visibility metric that measures how consistently a brand is mentioned or cited within AI-generated answers, specifically Google AI Overviews. It is both real and countable: each search either contains your brand or it does not, and those results are combined into a single percentage score.

The Share of Answer tool lets you enter a brand name, website, and search prompt. It runs that exact prompt five times against Google AI Overviews, detects brand mentions and clickable website citations in each result, and calculates your Share of Answer score. You can use it to uncover how visible your brand is in direct answers returned by Google's AI-powered search engine.

Each of the five searches scores 1 point if your brand was present, either through a brand mention in the AI Overview text or a clickable website citation in the source list. The five run scores are added up and divided by five, then multiplied by 100 to produce a percentage. A score of 80% means your brand appeared in 4 out of 5 searches.

AI Share of Voice typically measures a brand's relative presence across AI-generated content compared to competitors. It is a share of a competitive pool. Share of Answer focuses on a single brand's absolute consistency across repeated searches of the same prompt. Answer share captures whether your brand shows up at all, not how it ranks against others. Both are useful answer engine optimization metrics, but they answer different questions.

Answer engines are AI systems that return direct answers to questions rather than a list of links. Google AI Overviews, ChatGPT, and Perplexity are examples. These platforms often generate replies that cite specific sources or mention specific brands by name. As more searches resolve with direct answers rather than ranked pages, brand visibility in those answers becomes a meaningful measure of authority and trust.

Answer engine optimization (AEO) is the practice of improving how a brand appears in AI-generated direct answers. It involves creating content that directly addresses real questions people ask, earning citations from authoritative pages, and building the kind of topical authority that AI models draw on when generating responses. Share of Answer is a metric used to track the results of AEO efforts over time.

Each search run is checked for three signals: (1) the brand name appearing in the AI Overview text, (2) the brand's domain written as plain text in the answer, and (3) the domain cited as a clickable source in the AI Overview source list. All three are recorded individually. A search counts as "present" if any one of the three fires. The tool exports all signal details so you can see exactly what appeared in each search.

The Share of Answer tool currently measures brand visibility specifically in Google AI Overviews, which is where the majority of AI-assisted searches happen in standard web search. Tracking across different platforms such as ChatGPT or Perplexity requires separate tooling because those systems do not expose a standard search API with AI Overview data.

AI-generated search results can vary between requests. Using five searches provides a simple consistency measurement rather than relying on a single result that might be atypical. The score reflects how reliably your brand appears across repeated queries of the same prompt, which is a more useful optimization metric than a single data point.

Yes. If the AI Overview links to the submitted website as a source without writing the brand name in the answer text, that search still counts as present. The domain citation and brand mention signals are tracked separately, so you can see exactly which signal fired in each run.

No. Each search scores either 0 or 1 regardless of how many times the brand is mentioned or cited within that single result. The maximum score across five searches is 5, which equals 100%.

Traditional Share of Voice often measures rankings, advertising impressions, media mentions, or share of a competitive pool. Share of Answer is a narrower metric focused on inclusion within AI-generated direct answers from a search engine. It measures a single brand's absolute answer visibility across a set of searches, not relative competitive share.

Google SGE (Search Generative Experience) was the original name for what Google later launched publicly as AI Overviews. They refer to the same AI-powered answer feature in Google Search. Share of Answer measures brand visibility within these AI Overview results.

No. Share of Answer is an independent measurement created by ShareofAnswer.is. It is not affiliated with or endorsed by Google.

The CSV and JSON exports include the full AI Overview text for each search, all signals detected (brand mention, domain in text, domain cited), matched keyword variations, source domains, individual run scores, and a plain-English "what appeared" summary for each search. This gives you the raw data needed to analyze answer positioning and track visibility trends over time.
