GEOforge Research · Citation Data
When Google’s AI answers cite a brand’s own website, they leave the brand out of the text about four times in ten. ChatGPT almost never does. A citation is not a mention.
Many AI visibility reports count a brand as “visible” when its website appears in an answer’s source list. We tested how often that same answer actually names the brand. On ChatGPT it nearly always does. On Google it often does not.
GEOforge runs each brand’s tracked prompts against ChatGPT, Google AI Mode and Google AI Overviews and stores two things for every answer: the list of sources the engine attached, and a grade of the answer text. For this piece we kept 271,841 answers that came with a source list, from 25 brands that have a website on file, collected 13 July to 23 August and 31 August to 4 October 2026. (We skipped the week of 24 August, when Google’s source lists changed. More on that below.)
We asked two separate questions of each answer. First: does any cited source sit on the brand’s own website? Second: does the answer text name the brand? “Named” follows our grading rule: the brand appears in the prose as a specific organization, product or person tied to it. A source link on its own does not count. An answer that cites your site but does not name you is what we call cited but not named.
On Google, 43% of the time. Combining AI Mode and AI Overviews, 20,914 of 48,964 answers that cited a brand’s own website did not name the brand. On ChatGPT it was 224 of 8,496, or 3%.
Google cites brands it does not name. ChatGPT does not.

25 brands. The first weeks vary more on Google (AI Overviews was at 20% in the week of 13 July, and we have not found why); from the week of 27 July every week is above 35%. The week of 24 August is in the chart but excluded from the totals.
Google was not always this way in our data. In June (1 June to 12 July) the share was 37% in AI Mode and 31% in AI Overviews. Across 13 July to 23 August it was 43% and 42%, and it has stayed there since. ChatGPT stayed between 1% and 5% in every week.
It is concentrated, so we checked. The two brands with the most such answers account for 55% of Google’s cases. Without them, Google’s share is 30% rather than 43%: lower, but still more than 1 in 4 and still far from ChatGPT’s 3%.
Brand by brand, comparing only brands with at least 30 answers citing their site on both engines, Google left the brand out more often than ChatGPT in 15 of 15. The typical brand sees 38% on Google and 1% on ChatGPT (medians). The spread is wide, though, and two brands sit near the top of it for reasons we have not investigated.
| Brand | ChatGPT | Gap | |
|---|---|---|---|
| Brand A | 99% | 0% | 99 pts |
| Brand B | 96% | 64% | 31 pts |
| Brand C | 76% | 3% | 73 pts |
| Brand D | 65% | 29% | 36 pts |
| Brand E | 64% | 1% | 63 pts |
| Brand F | 51% | 0% | 51 pts |
| Brand G | 45% | 1% | 44 pts |
| Brand H | 38% | 0% | 38 pts |
| Brand I | 38% | 3% | 35 pts |
| Brand J | 30% | 0% | 30 pts |
| Brand K | 27% | 1% | 26 pts |
| Brand L | 18% | 0% | 18 pts |
| Brand M | 15% | 0% | 15 pts |
| Brand N | 14% | 4% | 10 pts |
| Brand O | 3% | 0% | 3 pts |
No, as far as we can tell. In the week of 24 August the number of sources Google AI Mode attached to each answer in our data roughly halved, and we cannot tell from our side whether Google or our data provider changed. If the shorter lists were driving this result, the share would have moved with them. It did not: Google was at 42.7% before and 42.8% after. ChatGPT, whose source lists did not change, works as the control.
The same before and after the change
Share of site-citing answers that do not name the brand. Open circle: 13 July to 23 August. Filled circle: 31 August to 4 October.
We also checked that no GEOforge collection or grading code relevant to this changed between June and early October. Our answer grader’s prompt was untouched in that period. Dropping the final week changes Google’s overall share to 43%.
The reverse is much more even. Among Google answers that named the brand, 22% did not cite the brand’s own site. For ChatGPT it was 17%. So the engines differ mainly in one direction: Google will lean on your content without crediting you in the text, while ChatGPT mostly cites the sites it talks about.
Data. 271,841 answers with source lists (209,902 from Google AI Mode and AI Overviews, the rest from ChatGPT) across 25 brands, 13 July to 23 August and 31 August to 4 October 2026. Only brands with a website on file are included. The week of 24 August is excluded from totals because collection volume and source-list length changed during it.
Classification. An answer “cites the brand’s site” when any source URL is on the brand’s own domain or a subdomain of it. An answer “names the brand” when our automated grader, which reads the answer text, judges that the brand is referred to as a specific organization in the prose. A source link alone does not count.
Checks. We split the data by week and before/after, compared brand by brand, removed the two largest brands, ran each engine separately, checked that the collector and grader code did not change, and compared against a June baseline. As a check on the grader, we took two weeks of Google answers from the seven brands with the most such cases, removed the source links from the answer text, and searched what was left for the brand’s name. For five of the seven, the name never appeared in any answer the grader had marked as not naming the brand. The other two have names that are also ordinary words or phrases, so a plain text search also catches everyday uses of those words (in 2% and 30% of their answers). The grader’s verdict holds up: in these answers the brand’s site is a source, and the brand is not in the prose.
Limitations. The prompts are the ones our clients track, so they lean B2B and are not a random sample of searches. The pooled figure is dominated by a few brands; the brand-level spread is wide. We cannot see why Google behaves differently from ChatGPT here. Every figure is aggregated and no brand or prompt is identified. See our earlier work on social platforms in AI citations and LinkedIn posts and articles for how the engines differ in other ways.
