Audit: 34.7% of Perplexity's Numeric Citations Point at a Page That Does Not Contain the Number
Haus Research asked perplexity/sonar and sonar-pro ten question templates about 210 technology companies (310 questions), then fetched every cited URL and checked whether the page actually held the figure it was cited for. Of 1,826 citations attached to numeric claims across 2,915 unique URLs, 34.7% pointed at a page that would not open or contained none of the sentence's figures; scored per claim instead of per citation, 14.4% of 872 claims fail. Dead links were only 1.3% of the problem, with paywalls at 16.1% and readable-but-unsupporting pages another 16.1%, and the datasets and scripts were published alongside the September 2 report.
