A new study from Writesonic reveals that roughly 40% of AI search citations fail to mention the source brand in their generated text. This phenomenon—dubbed 'ghost citations'—varies significantly across platforms, affecting engines like Perplexity, Google AI Mode, and ChatGPT. Consequently, tracking citation counts alone no longer provides business owners with an accurate picture of actual brand visibility.

According to new research from Similarweb, ChatGPT includes web citations in an average of just 6.8% of U.S. desktop answers, though link frequencies vary dramatically by industry. Travel and retail lead all categories with citation rates of 22.6% and 13.5%, respectively. Understanding these vertical attribution benchmarks is vital for local business owners building a competitive AI search visibility strategy.
