Build a question set
Separate navigation, information, comparison and action. Collect actual questions without unnecessary personal data. Record language, country and context; a result can help one intention while being unsuitable for another. Preserve how the examples were selected.
Define meaningful criteria
Specify accuracy, understandable sourcing, necessary freshness and ability to complete the task. Do not confuse visual preference with relevance. A short written rubric lets two reviewers discuss a concrete disagreement rather than comparing impressions.
Retain observations
Date captures and preserve weak examples alongside good ones. Results can vary, and one observation does not represent an entire engine. Separate advertising from non-advertising results in the analysis so different interfaces are not silently combined.
Explain limitations
State sample size, method and disagreements. For your own site, use findings to improve a missing answer or confusing journey. Do not turn a small assessment into a universal ranking of search engines.
