The short answer

The panel contains 237930 answers to questions asked in French and 63095 answers to questions asked in English, citing 100597 and 54603 distinct domains. The same platforms do not carry the same weight: the widest gap is Reddit, cited in 0.93% of French answers and 2.28% of English ones.

The same question in two languages does not return the same sources, and the difference is larger than most localisation plans assume.

Key figures

  • 301025 AI answers analysed between August 2025 and August 2026
  • 1820738 citations extracted from those answers
  • 131349 distinct domains cited at least once
  • 5 models measured separately: ChatGPT, Gemini, Perplexity, Claude and Grok
  • 79% of the questions asked in French, the rest in English

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.

What changed over 13 months

Platforms that weigh more in English: Reddit, Amazon, HubSpot. Platforms that weigh more in French: Trustpilot, YouTube, Wikipedia. A source plan translated from one market to the other misallocates on both.

What this means in practice

Community platforms weigh more in English, while review platforms and local marketplaces weigh more in French. The consequence for an international business is that a source strategy built on English data will misallocate budget in a French speaking market, and the reverse is equally true. It also means a translated page is not a localised strategy: the sources cited around it differ, so the local proof, listings and reviews have to exist in the local market.

How to use this study

  1. Build the source list per market rather than translating one plan.
  2. Collect reviews and listings in each market you sell to, not only in your home market.
  3. Measure citations per language, since a single global number hides the difference.

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.

Frequently questions asked

Which sources weigh most in French?

Wikipedia at 3.99%, ahead of Trustpilot at 3.24% and YouTube at 3.12%. The full ranking is on this page, and the source data is public on data.sorank.com.

How was this study measured?

On 301025 answers from five AI, collected between August 2025 and August 2026, with every cited source extracted and normalised. The citation rate is the number of citations per 100 measured answers. The public dataset is on data.sorank.com.

Which language does this panel describe best?

French, since it represents the large majority of the measured answers. The English subset is smaller and should be read as an indication of direction rather than as a precise measurement.
