EVALUATION FRAMEWORK

What the AI Visibility Engine Audits

AI search algorithms operate very differently from traditional search engines. We measure exactly how major LLMs understand, recommend, and cite your company.

VECTOR 01

Brand Mention & Appearance Rate

Measures whether ChatGPT, Gemini, and Perplexity include your business in top recommendations when users ask open-ended questions for your primary services.

VECTOR 02

Citation Link & Canonical Verification

Checks whether AI answers provide direct clickable links to your official website domain or rely exclusively on third-party aggregators and directories.

VECTOR 03

NAP, Address & Service Radius

Verifies that phone numbers, suite addresses, operating hours, and service territories cited in AI generated summaries are accurate and current.

VECTOR 04

JSON-LD & Knowledge Graph Entity Gaps

Diagnoses missing schema markup (`LocalBusiness`, `areaServed`, `hasOfferCatalog`) preventing LLMs from understanding your specific capabilities.

VECTOR 05

Competitor Share of Model Voice

Identifies which specific local competitors are consistently favored by AI engines, analyzing what citations and content authority drives their prominence.

VECTOR 06

Plain-English Optimization Action Plan

Translates raw LLM query findings into concrete website modifications: clear city pages, structured entity tags, and schema diffs you can hand to your developer.

Engine Technical Specifications
