How AI chooses sources and citations

What this means for businesses

• Measure AI answers as their own channel. Answers change run to run, so track how often you are named across many questions. See whether ChatGPT names your business with a free AI grade.
• Get on the lists AI reads. Most brand mentions come from third-party reviews, comparisons and forums, with Reddit cited most.
• Keep pages fresh and rank on Google. Most cited pages were updated in the past year, and top Google results are cited far more often.
• Fix your listings. Google Business Profile is the top AI source for local businesses, and AI tools still give wrong local details. Healthcare practices can start with AI and medical SEO.
• Track calls and conversions from AI. AI visitors are few but often convert above the site average.
