Why is not ChatGPT citing my B2B SaaS?
ChatGPT cites sites it treats as authoritative for a query. Most B2B SaaS sites lack three specific signals: structured data declaring entity identity, an llms.txt file, and citations from domains ChatGPT already trusts.
How do I get cited by Perplexity?
Perplexity cites sources it crawls + ranks for the live query. To get cited: allow PerplexityBot in robots.txt, ship answer-first content (FAQPage schema, BLUF paragraphs), and acquire citations from high-authority domains Perplexity already ranks.
What is Generative Engine Optimization (GEO)?
Generative Engine Optimization (GEO) is the practice of structuring web content so AI search engines like ChatGPT, Claude, Perplexity, and Gemini cite it in their responses. Unlike SEO which optimizes for keyword rankings, GEO optimizes for entity recognition, structured data, and citation probability.
ChatGPT vs Perplexity vs Gemini vs Claude for brand research?
All four AI engines surface brand information but cite sources differently. Perplexity shows explicit URL citations. ChatGPT blends training data with browsing. Claude prioritizes recency and reasoning. Gemini integrates live Google search results.
Why does ChatGPT say wrong things about my company?
ChatGPT hallucinations about your company come from three sources: outdated or thin training data, confusion with similarly-named companies, and absence of authoritative web sources for ChatGPT to ground its answers in. Each source has a different fix.
Why is my company invisible in AI search results?
AI engines surface companies they trust as authoritative for a query. Invisibility usually means one of three things: AI crawlers cannot access your site, your structured data does not identify your entity, or no high-authority source on the web mentions you.
