The short answer

Facebook is cited in 0.85% of measured answers over the last three months, which places it ninth of the platforms tracked. It is cited by all five models, most often by Grok at 3.81% and least often by Claude at 0.11%.

Facebook is close to invisible on the analytical models and a significant source on the community driven one.

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

Facebook model by model

  • Grok: 3.81%
  • Perplexity: 1.3%
  • Gemini: 0.94%
  • ChatGPT: 0.15%
  • Claude: 0.11%

The sectors where Facebook weighs most

  • Food and Beverage: 2.35%
  • Sports: 1.41%
  • Manufacturing: 1.35%
  • Travel: 1.33%
  • Retail: 1.03%
  • Entertainment: 0.95%

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 gap between the model that cites Facebook most and the one that cites it least is 3.7 points. That spread, not the average, is what should decide a budget: the same work returns most on Grok and least on Claude. Across all tracked platforms, Facebook ranks ninth.

What changed over 13 months

Over the 13 months measured, Facebook moved from 0.08% in August 2025 to 0.55% in August 2026, with a peak of 1.24% in July 2026. Averaged over the first three months against the last three, the movement is plus 0.65 points.

Month by month

  • August 2025: 0.08%
  • September 2025: 0.16%
  • October 2025: 0.24%
  • November 2025: 0.64%
  • December 2025: 0.19%
  • January 2026: 0.41%
  • February 2026: 0.89%
  • March 2026: 0.59%
  • April 2026: 0.3%
  • May 2026: 0.23%
  • June 2026: 0.59%
  • July 2026: 1.24%
  • August 2026: 0.55%

What this means in practice

The pattern matches how the platform is used rather than how marketers rank it: groups and local pages are where answers about local services, food and events get their material. That gives a real but narrow lever. A complete, current page with correct hours and location can be quoted for a local question, while the same page contributes almost nothing to a considered business purchase. Treat it as local infrastructure, not as a citation strategy.

How to use this study

  1. Keep the page factual and current if you serve a local market, especially hours, address and contact details.
  2. Do not expect group activity to influence the models that never cite the platform.
  3. Prioritise the review and map profiles first if your budget is limited.

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.
