4. Audit Scope and Boundaries
Audit scope of this report: ChatGPT's brand recommendation behavior for the laptop category across 5 independent attributes.
Excluded content: Real product performance test data, market share, sales data, user satisfaction surveys, independent evaluations of any brand's product quality, or inferences about the AI model's internal mechanisms or training data.
Important statement: All conclusions only reflect ChatGPT's output behavior under specific query conditions and do not constitute purchasing advice.
5. Methodology Overview
Attribute-Driven Approach: Predetermine 5 independent attribute dimensions and ask questions separately.
Single-Attribute Questioning Rule: Each question focuses on only one attribute.
Ranking + Recommendation Dual-Track Structure: Two types of questions per attribute.
Sampling Mechanism: Single round sampling, total of 10 independent AI responses.
6. Metric Definitions
Brand Mention Frequency (BMF): Total number of times a brand is mentioned across all 10 responses. Multiple mentions in the same response count as 1. Maximum value is 10.
Top-1 Presence: Number of responses where a brand is ranked first in Ranking or Recommendation questions, divided by the total number of responses of that type (denominator: 5 for Ranking, 5 for Recommendation).
Top-3 Presence: Number of Ranking responses where a brand appears in the top three, divided by total Ranking responses (5).
Recommendation Rate: Proportion of the 5 Recommendation questions where a brand is explicitly recommended (first choice or tied for first).
Ranking-Recommendation Gap: Ranking Top-1 share minus Recommendation rate. Positive value indicates stronger ranking, negative indicates stronger recommendation.
7. Question Framework
Attribute 1: Performance – Ranking (Q1) / Recommendation (Q6)
Attribute 2: Battery Life – Ranking (Q2) / Recommendation (Q7)
Attribute 3: Portability – Ranking (Q3) / Recommendation (Q8)
Attribute 4: Build Quality – Ranking (Q4) / Recommendation (Q9)
Attribute 5: Value for Money – Ranking (Q5) / Recommendation (Q10)
