What is an AI Visibility Score?
An AI Visibility Score is a quantitative measure of how prominently and favorably your brand appears in AI-generated responses across major platforms including ChatGPT, Google Gemini, Perplexity, Claude, and Grok.
Think of it as your brand's "share of voice" in AI-generated answers. Just as traditional share of voice measures your presence in advertising or media coverage, an AI Visibility Score measures your presence in the answers that AI assistants give to millions of users every day.
Why Traditional Metrics Don't Work
Traditional digital marketing metrics — search rankings, website traffic, social media impressions — don't capture AI visibility at all. Your brand could rank #1 on Google for a target keyword and still be completely absent from ChatGPT's answer to the same question.
This blind spot is dangerous. As more consumers and business buyers turn to AI assistants for recommendations, brands that only measure traditional channels are missing an increasingly important discovery surface. The AI Visibility Score fills this gap.
How the Score is Calculated
The sig.ai platform calculates AI Visibility Scores using a multi-dimensional methodology that accounts for several factors:
1. Mention Frequency
How often does each AI platform mention your brand when responding to relevant queries? We test hundreds of industry-specific prompts across all major AI engines and track whether your brand appears in the response.
This isn't just a binary yes/no. We measure:
- Primary mentions — your brand is the first or main recommendation
- Secondary mentions — your brand is listed among alternatives
- Contextual mentions — your brand is referenced in a comparison or discussion
- Absence — your brand is not mentioned despite being relevant
2. Recommendation Sentiment
When AI models mention your brand, what do they say? The sentiment dimension captures whether the AI positions your brand positively, neutrally, or with caveats. A brand that's mentioned frequently but always with disclaimers ("however, some users report issues with...") will score lower than one mentioned with clear endorsement.
3. Cross-Platform Consistency
The score accounts for performance across all major AI platforms. A brand that scores well on ChatGPT but is absent from Gemini and Claude has a lower overall score than one with consistent visibility across all platforms.
Different AI models have different training data and recommendation patterns. The brands that perform best invest in broad entity presence that resonates across all major models, not just one.
4. Competitive Positioning
Your score is partially relative — it reflects how you compare to competitors in your category. If you're the most-mentioned brand in your industry across AI platforms, your competitive positioning score is high. If competitors consistently outrank you in AI recommendations, that pulls your score down.
The comparison tool breaks this down by competitor, showing exactly where you lead and where you trail.
5. Query Coverage
Not all queries are equally important. The score weights queries by business relevance — high-intent purchase queries carry more weight than general informational queries. If the AI recommends you for "best enterprise CRM" but not for "what is CRM software", the high-intent query matters more.
Score Ranges and What They Mean
AI Visibility Scores range from 0 to 100:
- 80-100: Dominant. Your brand is consistently mentioned as a top recommendation across major AI platforms. You're well-positioned for AI-mediated discovery.
- 60-79: Strong. Your brand appears frequently in AI responses but has gaps — perhaps on specific platforms or for certain query types. Targeted optimization can push you higher.
- 40-59: Moderate. Your brand is mentioned sometimes but inconsistently. Competitors likely dominate several key query categories. Significant opportunity exists.
- 20-39: Weak. Your brand is rarely mentioned in AI-generated answers. Your competitors are capturing AI-mediated demand that should be yours.
- 0-19: Invisible. AI assistants essentially don't know your brand exists. Urgent action needed — every day of inaction allows competitors to compound their advantage.
How to Improve Your Score
Improving your AI Visibility Score requires a systematic approach across several dimensions:
Build Entity Authority
The most impactful action is strengthening your brand's entity presence across the web. This means earning mentions in industry publications, review platforms, analyst reports, community forums, and news outlets. The more diverse and authoritative your sources, the stronger your entity representation in AI models.
Optimize Content for Extraction
Ensure your website content is structured for AI extraction. Use FAQ schemas, comparison tables, clear product definitions, and structured data markup. When you answer a question on your site, answer it directly in the first sentence, then elaborate. This is exactly how AI models prefer to source information.
Monitor and Respond to Changes
AI model updates can shift brand visibility overnight. Regular monitoring with the sig.ai dashboard alerts you to changes before they compound. If a competitor gains ground after a model update, you can respond quickly with targeted entity building.
Address Cross-Platform Gaps
If your score is strong on ChatGPT but weak on Gemini, investigate why. Different models weight different sources. The platform-level breakdown in your sig.ai dashboard reveals exactly which AI engines need attention.
