RankAI FAQ: What Google Indexes vs. What AI Engines Answer
Use the RankAI FAQ to keep two things apart: what Google indexes and what can surface in answers from ChatGPT, Perplexity, Gemini, Grok and Google AI.
Say you have a page live on your site. Google can read it and index it. An AI engine can quote it or rework its content in an answer. Those are two different observations, and the RankAI FAQ page exists to keep them from blurring together. If you want to know how to use it to separate what Google indexes from what can surface in answers from ChatGPT, Perplexity, Gemini, Grok and Google AI, that is the starting point. The public pages name ChatGPT, Perplexity, Gemini, Grok and Google AI. Claude and Grok are measured only after you connect them. Gemini and Google AI Overviews are not the same observation.
Why the FAQ is the right place to separate the two
The RankAI FAQ collects recurring questions and practical answers. Treat it as a reading map: on one side, what concerns Google indexing; on the other, what concerns presence in the answers of the AI engines named above. It is not a list of ranking promises. It is a way to set up the observation without mixing the two levels.
How to proceed, step by step
- Start from the question, not the engine. Open the FAQ and find the entry that matches your doubt. Check: the answer must name the phenomenon explicitly (Google indexing or an AI engine answer) and must not blend them in the same sentence.
- Record the two observations separately. For each page, write two distinct lines: one on what Google indexes, one on what can surface in answers from ChatGPT, Perplexity, Gemini, Grok and Google AI. Check: if the two lines run together, the note is unusable and needs rewriting.
- Treat Gemini and Google AI Overviews as separate entries. In the FAQ and in your notes, do not merge them: they are different observations. Check: every time “Google AI” appears, make sure it is not standing in for “Gemini,” or the other way round.
- Mark the connection status. Claude and Grok are measured only after you connect them. Until then, they are not observed. Check: the note says “not connected” or “connected,” with no ambiguity.
- Reread the FAQ after each check. Go back to the entry and compare your note with the page's answer. Check: the note cites the FAQ entry it started from, so the comparison stays traceable.
A reading method RankAI proposes
What follows is a practical proposal from RankAI, not a universal standard: use the FAQ as a register of distinctions, not as a list of results. In practice, whenever a page comes up, the FAQ should help you answer two separate questions: “Is this page indexed by Google?” and “Can this content surface in the answers of the AI engines named above?” If either answer is missing, the note is incomplete.
The specific contribution of this piece is a reading habit: treat the FAQ as a dictionary of differences, not a leaderboard. When a page interests you, open the matching entry and write two columns: on the left, what concerns Google and indexing; on the right, what concerns AI engine answers. In the right-hand column, use the exact engine name — ChatGPT, Perplexity, Gemini, Grok or Google AI — with no lumping together. If you are looking at Gemini, do not write Google AI Overviews; if you are looking at Google AI Overviews, do not write Gemini. Add a line on connection status for Claude and Grok, because they become observable only after you connect them. Finally, reread the FAQ entry and check that your two columns have not merged: if a sentence contains both indexing and an AI answer, split it. This method produces no numbers and no forecasts. It produces comparable notes, which is what you need to keep the two phenomena apart.
One limit to keep in mind
The RankAI FAQ helps you tell the phenomena apart, but it does not guarantee that a page indexed by Google will appear in answers from ChatGPT, Perplexity, Gemini, Grok or Google AI, or the reverse. Also, an API response is not a person's screen: do not treat the two as equivalent when you record an observation.
