SourceBench - Shopping: leaderboard

Metric: Weighted source-quality score on a 20 to 100 scale: every web page an answer cites is rated 1 to 5 on eight rubrics (content relevance, factual accuracy and objectivity weighted 1.5; freshness, ownership accountability, author accountability, domain authority and layout clarity weighted 1) by a few-shot Qwen-Plus evaluator calibrated on human labels, and the weighted mean is scaled so 100 is the maximum; the 20 product search queries (VA-COS NLQ); search-equipped LLMs answer real user queries with their own web search, and the URLs in the final answer are scored; higher is better. Source: arxiv.org. Saturation forecast: Around June 2027. 8 models tracked.
