To identify competitor share in AI responses<\/strong>, measure how often your brand and named competitors appear in the same, predefined set of buyer prompts across multiple AI engines. Then separate mentions, recommendations, citations, sentiment, and position so you can explain why<\/em> one competitor receives more visibility.<\/p>\n

Unlike traditional search rankings, AI visibility is distributed across answer text, recommendation lists, citations, and product comparisons. A defensible measurement system therefore needs a fixed prompt set, stable competitor definitions, repeatable runs, and preserved raw answers.<\/p>\n

What is competitor share in AI responses?<\/h2>\n

Competitor share in AI responses is the proportion of tracked AI-answer visibility attributed to each brand within a defined market, prompt set, engine group, and time period.<\/p>\n

A simple mention-based formula is:<\/p>\n

Competitor AI Share of Voice (%) =\nBrand Mentions \u00f7 Total Tracked Brand Mentions \u00d7 100\n<\/code><\/pre>\n
For example, if your brand receives 32 mentions and three competitors receive 68 combined mentions, your share is:<\/p>\n
32 \u00f7 (32 + 68) \u00d7 100 = 32%\n<\/code><\/pre>\n
This is different from mention rate<\/strong>, which measures the percentage of answers containing your brand:<\/p>\n
Mention Rate (%) =\nAnswers Containing Your Brand \u00f7 Total Answers \u00d7 100\n<\/code><\/pre>\n
A brand can have a high mention rate but a lower share of voice when several competitors are repeatedly named in the same answers. Leading measurement guides recommend keeping these denominators separate rather than combining them into one ambiguous score. (maxaeo.ai<\/a>)<\/p>\n
Which signals should you measure?<\/h2>\n
The most useful competitor analysis uses five related but distinct signals:<\/p>\n
\n\n\n\n\n\n\n\n\n\n
Signal<\/th>\nWhat it answers<\/th>\nWhy it matters<\/th>\n<\/tr>\n<\/thead>\n
Mention rate<\/td>\nHow often does the brand appear?<\/td>\nMeasures coverage<\/td>\n<\/tr>\n
Share of voice<\/td>\nHow much of the competitive conversation does it own?<\/td>\nMeasures relative visibility<\/td>\n<\/tr>\n

Sentiment and framing<\/td>\nHow is the brand described?<\/td>\nReveals positioning quality<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
Do not treat a mention as a recommendation. A brand may appear as an alternative, a niche option, a budget tool, or a poor fit. The commercial meaning changes substantially between those framings.<\/p>\n
MaxAEO\u2019s public monitoring model combines brand mentions, competitive ranking, sentiment, citations, and the original AI answers so teams can trace a metric back to the sentence and source that produced it. Its coverage includes ChatGPT, Perplexity, Gemini, Claude, Copilot, Grok, Google AI Mode, and Google AI Overview. (maxaeo.ai<\/a>)<\/p>\n
How do you build a reliable competitor-share dataset?<\/h2>\n
Start by defining the measurement boundary before collecting answers. A useful dataset has four fixed dimensions:<\/p>\n
    \n
  1. \n
    Prompt universe<\/strong>
    \nInclude category, use-case, audience, comparison, alternative, and buying-criteria questions.<\/p>\n<\/li>\n
  2. \n
    Competitor set<\/strong>
    \nTrack your brand plus direct alternatives that buyers genuinely compare. For an AI visibility platform, this might include Peec AI and Otterly alongside other relevant products.<\/p>\n<\/li>\n
  3. \n
    Engine and market configuration<\/strong>
    \nRecord the AI engine, product surface, language, geography, model mode where available, and run date.<\/p>\n<\/li>\n
  4. \n
    Counting rule<\/strong>
    \nDecide whether one brand appearing twice in one answer counts as one mention or two. Keep the rule unchanged across reporting periods.<\/p>\n<\/li>\n<\/ol>\n
    For an initial SaaS audit, a practical starting point is 20\u201340 prompts across at least four AI engines<\/strong>, followed by daily or weekly re-runs. The exact number is less important than keeping the prompt version stable. Search-industry methodologies consistently warn that changing prompts, markets, or model surfaces can create false performance changes. (llmpulse.ai<\/a>)<\/p>\n
    How do you calculate competitor share by engine?<\/h2>\n
    Calculate each engine separately before creating a cross-engine total.<\/p>\n
    ChatGPT Share =\nYour ChatGPT Mentions \u00f7 All Tracked ChatGPT Mentions \u00d7 100\n\nPerplexity Share =\nYour Perplexity Mentions \u00f7 All Tracked Perplexity Mentions \u00d7 100\n<\/code><\/pre>\n
    This separation exposes gaps that an overall average can hide. For example, your brand may be frequently mentioned in ChatGPT but rarely cited in Perplexity. That suggests a different problem from low visibility everywhere: the first may involve answer framing, while the second may involve source availability or citation eligibility.<\/p>\n
    Avoid averaging percentages from engines with different numbers of prompts. Aggregate the underlying mention events first:<\/p>\n
    Combined Share =\nTotal Brand Mentions Across Included Engines\n\u00f7\nTotal Tracked Brand Mentions Across Included Engines \u00d7 100\n<\/code><\/pre>\n
    If strategic reporting requires weighting\u2014for example, assigning greater importance to an engine used heavily by your buyers\u2014document the weights and keep them stable. Cross-model aggregation guidance also recommends calculating from raw event counts rather than averaging platform percentages. (llmpulse.ai<\/a>)<\/p>\n

    How do you reverse-engineer a competitor\u2019s advantage?<\/h2>\n
    The most actionable analysis connects competitor share to the evidence behind it. Use a four-layer attribution model:<\/p>\n

    Find the exact questions where the competitor appears and your brand does not. Group these by intent:<\/p>\n
