87.7% of the Pages ChatGPT Cites Aren't on Google's First Page

A home gardener asks ChatGPT when to plant tomatoes, then runs the same search on Google. The two sets of sources barely overlap. The blogs and guides ChatGPT cites are mostly websites that Google does not show anywhere on its first page for that question.

For a business or publisher, that is an opening. Getting cited by ChatGPT does not require beating the websites that hold Google's top 10, because ChatGPT draws most of its sources from outside that list. It also means your Google rankings say little about where you stand in ChatGPT.

87.7% of the pages ChatGPT cites are missing from Google's first page for the same question. Counting whole websites, 66.2% have no page in Google's top 10, and in 41.9% of answers none of the cited websites are on it.

On September 23, 2026 we asked ChatGPT 2,984 general questions twice each, with web search turned on, across topics from recipes and gardening to taxes and software. The same day we recorded Google's top 10 organic results, the unpaid listings on the first page, for the same questions from a US search. 5,836 ChatGPT answers cited at least one source.

For each answer we listed the distinct websites ChatGPT cited, 12,298 website citations in all, and checked each one against the websites in Google's top 10 for that question. A website counts as on page one if any of its pages ranks in Google's top 10. We repeated the check page by page for the 20,275 individual pages ChatGPT cited, where a page counts only if that exact page is in Google's top 10.

Two in three websites that ChatGPT uses to build an answer are ones a Google searcher would not see on page one. ChatGPT runs its own searches and weighs sources in its own way, so its list of sources and Google's first page are largely separate sets.

That is good news for websites that have never cracked Google's top 10. ChatGPT is not simply reading Google's first page back to the user, so a website that answers a question well has a real chance of being cited without holding a top Google ranking.

Comparing websites is a generous test, because a large website can rank in Google's top 10 with one page while ChatGPT cites a different one. Measured page by page, 87.7% of the pages ChatGPT cites are not in Google's top 10 for the question. About one cited page in eight is a page Google shows on its first page.

The view across whole answers is the starkest. In 41.9% of ChatGPT answers that cite sources, not a single cited website appears in Google's top 10. Someone who reads that ChatGPT answer and someone who reads Google's first page are looking at entirely different sources for the same question.

The gap is widest where many websites publish similar content. In answers to recipe questions, 88.5% of cited websites are missing from Google's first page, followed by beauty at 82.9%, gardening at 81.8% and personal finance at 80%. Real estate, cars, home and parenting all sit between 75.2% and 78.6%.

In these topics there is no single obvious source. Many blogs, publishers and hobby websites cover the same questions, so Google and ChatGPT each pick from a large pool and rarely pick the same websites. For a small publisher in a crowded niche, ChatGPT is the easier place to be seen.

Where one kind of website clearly owns the answer, ChatGPT and Google agree much more often. In answers to software questions, 20% of cited websites are missing from Google's top 10, and in answers to tax questions 27.6%, less than half the 66.2% average. Shopping (34.6%), weather (36.3%) and tech (37.2%) are also well below average.

The reason is the same in each case: a software question is best answered by the vendor, a tax question by the tax authority, a weather question by a forecasting service. Both Google and ChatGPT find those sources, so the websites that rank on Google's first page are also the ones ChatGPT cites. Health and mental health sit in the middle, at 53.8% and 55.3%.

If you cannot break into Google's top 10 in a crowded topic, ChatGPT is a second route to readers. Two in three of the websites it cites are not on Google's first page, so a clear, specific page that answers the question directly can win a citation that a Google ranking would never deliver.

Start by asking ChatGPT the questions your customers ask and noting which websites it cites. If they are websites like yours rather than the big names on Google's first page, write pages that answer those exact questions in the first few lines, with specific figures, steps and examples.

In topics with a clear authority, such as software and taxes, the reverse applies: the same websites win both, and ranking on Google and being cited by ChatGPT are close to one job. Working with an ai seo company shows you which websites ChatGPT cites for your topic and how to join them.
