Transportation AI Citation Study: 1800 AI Answers Measured

The short answer

In Transportation, 1800 AI answers were measured between May 2026 and August 2026. The most cited platform is TripAdvisor at 2.27%, ahead of Leboncoin at 2.17%. That ranking differs from the general one: Leboncoin is cited 14.5 times more here than in the general ranking.

Transportation is the sector where a national classifieds platform reaches its highest position of the entire dataset.

How to read these numbers

A citation rate of 2% means the source was cited twice for every 100 measured answers. Rates are computed per model against the number of answers of that model, so a model with a smaller sample never distorts a column. A source cited several times inside one answer is counted once per company block, which keeps a single verbose answer from dominating a month.

The distribution is worth as much as the ranking. The top three sources hold 65% of the citations counted in this table, 4 platforms sit above 1%, and TripAdvisor and Leboncoin are close enough to be treated as one tier. A market where three sources hold most of the citations rewards depth on those three rather than presence everywhere.

This sector was measured on 1800 answers, 57.5% of them in French, across 3 of the five models (ChatGPT, Gemini, Perplexity). The language mix matters when you read the ranking, because local platforms weigh more in French speaking markets.

What changed over the measured period

This sector was measured over 4 months, between May 2026 and August 2026, on 1800 answers, and 14 platforms recorded at least one citation. Its leading source, TripAdvisor, held its position at 1.33% between May 2026 and August 2026, which is unusual in a dataset where most sources move by a point or more in a quarter.

TripAdvisor month by month in this sector

• May 2026: 1.33%
• June 2026: 0%
• July 2026: 3.73%
• August 2026: 1.33%

What this means in practice

Vehicle and transport questions are answered from marketplaces and traveller platforms, both of which aggregate comparable, structured listings. Company sites appear far behind. For an operator or a dealer, the visibility work is therefore listing work: complete entries, accurate specifications, and consistent naming across platforms. The sector also has one of the more balanced language splits in the panel, which suggests the pattern is not purely local.

How to use this study

1. Keep marketplace listings complete and consistent with your own inventory pages.
2. Publish specifications as text on your site so you can be cited directly.
3. Maintain the traveller facing profiles if you carry passengers.

How this study was measured

1. We run a panel of buyer questions every month, the questions people type before choosing a supplier.
2. Every question is sent to five AI: ChatGPT, Gemini, Perplexity, Claude and Grok.
3. Every answer is parsed, every cited source is extracted and normalised to a domain and a platform.
4. The citation rate is the number of citations of a source per 100 measured answers, computed per model so an uneven number of answers per model never distorts a column.
5. The month is closed, the dataset is rebuilt, and the public files are republished on data.sorank.com.

Limits of this study

1. This panel is not a neutral sample of the web. The questions come from the sectors our users operate in.
2. The panel leans French: 237930 answers come from questions asked in French and 63095 from questions asked in English.
3. Model coverage is uneven: 87008 answers from ChatGPT, 87004 from Perplexity, 87000 from Gemini, 20011 from Claude and 20002 from Grok. The two smallest samples are read as direction rather than as precise values.
4. A citation is not a click. This study measures what the AIs cite, not what a reader does next.
