How Collimer Scores AI Visibility

Every score is reproducible. Here is exactly what we ask, who we ask, and how we calculate the result.

Prompt categories

A standard scan fires 25 prompts across five buyer-journey stages, each generated fresh for your brand and domain. The category mix reflects where buyers actually are in their decision process.

Problem-led 30%

Buyers describe pain, not your name. If you're absent here, you're invisible at the top of the funnel.

"What tool helps a B2B SaaS team track churn?"

Category-aware 25%

When buyers already know the category they need, your brand must appear as a credible option.

"What are the best AI-visibility platforms for marketing teams?"

Brand 20%

Direct brand queries test whether AI actually knows what you do. That is the baseline of factual authority.

"Tell me about Acme Analytics and what they offer."

Alternative-seeking 15%

Buyers considering a switch ask for alternatives. Appearing here turns competitive pressure into pipeline.

"What are the best alternatives to Competitor X?"

Comparison 10%

Direct head-to-head questions are the highest-intent queries at the bottom of the funnel.

"How does Acme Analytics compare to Rival Y?"

Scoring formula

Each model response produces one result. Results are scored individually, then averaged across all prompts and models to produce the final 0–100 score.

Per-response score

score = base × mention × sentiment × citation × position_decay
  • base = 100
  • mention = 1.0 if brand appears, 0.0 if not
  • sentiment = 1.2 positive · 1.0 neutral · 0.7 negative
  • citation = 1.0 (wiring in progress; currently neutral)
  • position_decay = rank 1 → 1.00  · rank 2 → 0.85  · rank 3 → 0.72  · rank 4 → 0.61  · rank 5+ → 0.50

Final score

final = mean(per_response_scores), clamped to [0, 100]

Example: 3 prompts, 1 model

Prompt Mentioned Rank Sentiment Score
Awareness #1 yes 1 neutral 100 × 1.0 × 1.0 × 1.00 = 100
Evaluation #1 yes 3 positive 100 × 1.0 × 1.2 × 0.72 = 86
Comparison #1 no n/a n/a 100 × 0.0 × n/a × n/a = 0
Visibility score mean(100, 86, 0) = 62
