Data study of 301025 AI answers: how often Facebook is cited by ChatGPT, Gemini, Perplexity, Claude and Grok, month by month over 13 months.

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.
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.
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.
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.

Facebook is cited by all five models measured. Grok cites it most, in 3.81% of its answers, and Claude least, in 0.11%. The full model by model breakdown is on this page.
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.
For local businesses it remains part of the basic record the models can read. For business to business sellers, this dataset offers no evidence that it produces citations worth an investment.
