Large Language Models (LLM) & AI Market: AI Chat Tools Rely Mostly on YouTube and Reddit
Blinq analyzed 250,000 AI-generated answers from ChatGPT, Google AI Overviews and Perplexity, queried daily from January–June 2026, to map which sources these services cite. Corporate websites (official sites, blogs and landing pages) constitute about 66.2% of cited sources. On the domain level, YouTube (15.18%) and Reddit (14.55%) are the single most-cited addresses, followed by Wikipedia (9.05%) and LinkedIn (7.12%). The study finds service-level differences: ChatGPT leans more to reference and news sites, Google AI Overviews heavily cites user-generated platforms (notably YouTube), and Perplexity mixes community and publisher sources. Among German news domains, Die Welt (≈17%), Handelsblatt (≈12%) and Chip (≈9%) are most cited. Authors warn that citations do not guarantee reliability and advise critical checking—especially for sensitive topics—and stress multi-channel visibility for companies.
Study shows where AI chat tools source information (heavy reliance on user-generated platforms and company sites), with implications for publisher traffic, content credibility, search behavior and potential health risks.
