The AIO Index
The AIO Index is Signal AIO's proprietary scoring methodology for measuring brand visibility across AI platforms. Every brand scored through Signal AIO receives an AIO Index from 0 to 100.
Score Components
- Mention Rate (30%): How frequently the brand is cited in a representative set of industry-relevant prompts
- Citation Quality (25%): The authority level of sources AI models reference when discussing the brand
- Accuracy Score (20%): The correctness of AI-generated descriptions of the brand's products, services, location, and attributes
- Sentiment (15%): The positive/neutral/negative tone of AI-generated mentions
- Competitor Position (10%): Where the brand ranks relative to named competitors in head-to-head AI recommendation scenarios
Score Benchmarks
- 80–100: Excellent — brand is well-understood, frequently and accurately recommended
- 60–79: Good — strong presence with addressable gaps
- 40–59: Moderate — inconsistent representation across platforms
- 0–39: Poor — largely absent or inaccurately represented by AI
Platform Coverage
The AIO Index aggregates results across ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Grok (xAI), and Perplexity. Each platform is tested independently, and the scores are weighted and combined.
