RankAI FAQ: Google reads a site, AI tools answer
The RankAI FAQ is a map of the right questions, not a list of ready answers. It helps you keep Google reading and AI answers as separate observations.
If you are asking how to use the RankAI FAQ to understand what it means to read a site with Google and with ChatGPT, Perplexity, Gemini, Grok and Google AI, here is the practical answer: use the FAQ as a map of the right questions, not as a list of ready-made answers. Say you have to explain to a colleague why a page is found by Google but is not cited in a ChatGPT answer. The RankAI FAQ helps you separate the two observations before you draw any conclusions. 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.
Read the FAQ as a set of distinctions, not a ranking
The most common confusion is treating “Google reading” and “an AI assistant answering” as the same phenomenon. They are not. The RankAI FAQ makes clear that these are different observations, and that changes how you read the results. A page can be readable for Google and still not appear in the way ChatGPT, Perplexity, Gemini, Grok or Google AI phrases an answer.
The point is not to decide who “reads better.” It is to know which question you are asking. If the question is “does Google index and show this page?”, you are observing one thing. If the question is “how does ChatGPT answer on this topic?”, you are observing another. The FAQ exists to keep the two from being blurred together.
How to use it in practice: three steps with checkable criteria
This is an operational proposal from RankAI, not a universal standard. Its purpose is to make comparisons repeatable.
- Define the observation before you look at the data. Checkable criterion: write down which engine or assistant you are querying and the exact question you are asking. If the question is about Google, do not put a ChatGPT answer on the same line. If it is about Gemini, remember that Gemini and Google AI Overviews are not the same observation: note them separately.
- Check what the FAQ says about the engine you are using. Checkable criterion: the FAQ must explicitly name ChatGPT, Perplexity, Gemini, Grok or Google AI. If you are thinking about Claude or Grok, remember that they are measured only after you connect them. Without a connection you do not have an observation, you have a hypothesis.
- Treat an API response as technical data, not as someone's screen. Checkable criterion: if the result comes from an API, write that next to the result. An API response is not a person's screen: the interface may show different sources, contexts or formats. Do not use that data to describe what a user sees on screen.
The point the FAQ makes obvious
The RankAI FAQ is useful because it forces you to name the subject of the observation. “Google reads the site” and “ChatGPT answers on a topic” sound close, but they describe different things. Likewise, Gemini and Google AI Overviews are not the same observation: keep them separate even when the product name suggests a family connection.
This does not mean one reading matters more than the other. It means that if you mix them, you get a conclusion you cannot verify. The FAQ gives you the vocabulary to keep them apart.
The specific contribution of this piece is a rule for clean observation: before you compare Google with ChatGPT, Perplexity, Gemini, Grok or Google AI, write one line for each observation with three elements — the subject you queried, the exact question, and the type of answer you got (interface or API). If one of the three is missing, that data point does not belong in the comparison. In practice, this prevents the most frequent mistake: attributing to “Google” a behavior seen in an AI answer, or attributing to “ChatGPT” a result that is only about indexing. The RankAI FAQ then works as a filter: it does not tell you what to think, it tells you which questions you can ask without confusing the two levels. It is an operational proposal from RankAI, not a universal standard, and it should be adapted to your case.
A limit to keep in mind
The RankAI FAQ clarifies the distinctions between observations, but it does not replace checking your own site: on its own it does not produce a judgment on how a page is read or cited. The checkable limit is this: if you have not noted the subject, the question and the type of answer, the comparison between Google and AI assistants remains an impression, not an observation.
