Google's search engine uses over 200 ranking factors. ChatGPT, Perplexity and Gemini operate on a different logic — they don't "index" pages the same way, and they don't look at the same signals. AI search ranking factors exist, but they aren't a copy of Google's playbook. If you want to understand how AI actually decides what to include in its answers, here are the factors that matter.
This matters because more and more customers skip Google and ask AI directly. Traditional SEO is still important, but it's not enough on its own. AI pulls information differently, and once you understand how, you can influence whether you show up in the answer.
How is AI different from Google?
Google builds an index — it crawls billions of pages and returns links based on its algorithm. AI like ChatGPT doesn't work that way. It was trained on massive amounts of text, and when you ask it a question, it generates an answer based on what it learned. It doesn't "search" your site — it uses information that's in its training data or that it pulls in real-time from trusted sources.
In practice this means: you could be #1 in Google results, but AI won't mention you if your information isn't in its data in a consistent way.
What factors actually determine AI visibility?
AI doesn't publish its algorithm — nobody knows the exact formula. But repeated observations and testing show these factors coming up again and again:
- Information consistency. AI trusts information that appears the same way across multiple sources. If your business info conflicts across different sites, AI will likely leave it out.
- Citation volume and quality. Being linked from well-known sites signals credibility. Link building works here too — but the emphasis is on trustworthiness, not quantity.
- Structured data. Schema.org markup helps AI understand what your site is about. FAQ schema, business data, and product markup are particularly valuable.
- Site age and history. Older, established sites get more mentions than brand new ones. AI treats longer track records as a signal of permanence.
- Q&A format. AI loves content that's already distilled into answers. Clear question-and-answer structures, FAQs, and direct responses tend to surface.
AI is not a search engine — it's a reasoning engine. It doesn't find you, it deduces you. If you want to be deduced, make yourself deducible.
How does traditional SEO change in the AI era?
Technical SEO isn't dead, but its weight shifts. Page speed and mobile-friendliness still matter, but they aren't direct AI ranking signals. AI doesn't measure Core Web Vitals — it measures trust, consistency, and how well your information is described.
What works in both worlds is clear, high-quality content that answers what your customers are actually asking. If you write content that helps a human, it will likely help AI too. I covered this in more detail in the Generative Engine Optimization guide.
Five practical steps to improve AI visibility
None of these require a new website or a big budget. These are things you can do this week:
- Audit your info. Check every place your business appears online — Google Business Profile, Facebook, directories, your own site. The information must match exactly everywhere.
- Add schema.org markup. The most important ones: Organization, LocalBusiness, FAQPage, and Article. These tell AI in machine language who you are and what you do.
- Write an FAQ section. List 3–5 common customer questions and answer them clearly on the same page. This is directly usable format for AI.
- Get mentioned elsewhere. One mention on a reputable industry site can matter more than ten weak ones. Focus on quality.
- Update content regularly. AI often uses the freshest information available. Stale content gets passed over.
Summary
AI search ranking factors don't replace traditional SEO — they layer on top of it. Technical optimization doesn't hurt, but it won't solve AI visibility on its own. What matters most is consistent, structured, and trustworthy information that's easy for AI to use. Focus on content clarity, data consistency, and getting cited by other reliable sources.
