BrandCitation Methodology
How BrandCitation measures AI search visibility across Gemini, Perplexity, and OpenAI-powered models.
Last updated: May 18, 2026
What we measure
BrandCitation measures AI search visibility by sending buyer-intent prompts to AI engines and analyzing the responses. For each prompt and engine combination, we track:
- Whether your brand is mentioned
- Whether your domain is cited as a source
- How often competitors appear
- Position in recommendation lists
- Sentiment (positive, neutral, negative)
- Source URLs and domains that influence answers
- Visibility changes over time (for monitoring plans)
Important disclaimer
API-based results may differ from consumer UI results in ChatGPT, Gemini, Claude, Perplexity, or Google AI products. BrandCitation uses official APIs because they are scalable and reliable for trend monitoring. We clearly state this in every report.
AI engines
Gemini
Broad AI model visibility and cost-effective testing at scale.
Perplexity
Web-grounded AI search with source citations — the most valuable engine for citation analysis.
OpenAI-powered models
Additional model coverage. API results do not perfectly equal ChatGPT web browsing answers.
Prompt categories
Brand prompts
Test whether AI understands your brand entity: “What is {brand}?”, “Is {brand} legit?”
Category prompts
Test discovery when users do not know your brand: “Best {category} in {market}”
Competitor prompts
Benchmark against alternatives: “{brand} vs {competitor}”, “Alternatives to {competitor}”
Problem/solution prompts
Real buyer problems: “I need a tool to {job-to-be-done}”
Local and MENA prompts
Regional visibility in English and Arabic, including Egyptian dialect variations.
Sampling and cadence
LLMs are probabilistic — one answer does not represent permanent visibility. The free scan runs once. Paid audits run 15–50 prompts across engines. Monitoring plans run weekly (or daily for premium tiers) to track trends.
Brand matching
We detect brand presence via exact name match, case-insensitive match, and domain match in response text.
Citation detection
Citations are counted when:
- The engine returns URL sources directly (Perplexity-style)
- Response text includes your domain URL
- Cited source page domain matches your domain
Competitor share-of-voice
For each prompt set: your brand mentions divided by total mentions of all tracked brands. Example: 2 client mentions vs. 8 competitor A + 5 competitor B = 13.3% share-of-voice.
Recommendations
Action plans are based on missing mentions, citation gaps, competitor source patterns, technical GEO readiness, content gaps, and Arabic/English coverage imbalances.
