Reddit の AI 引用調査：Reddit は AI に引用されるきっかけになるか？

The short answer

Reddit is cited in 1.48% of measured answers over the last three months, which places it fourth of the platforms tracked. It is cited by 4 of the five models, most often by Grok at 4.11% and least often by Claude at 0%.

Reddit looks moderate on average and that average hides everything: it is a leading source on one model and a non source on another.

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

Reddit model by model

• Grok: 4.11%
• Gemini: 2.5%
• Perplexity: 1.51%
• ChatGPT: 0.33%
• Claude: 0%

The sectors where Reddit weighs most

• Manufacturing: 5.55%
• Telecommunications: 4.22%
• Entertainment: 3.1%
• Education: 2.73%
• Media: 2.39%
• Retail: 2.23%

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 Reddit most and the one that cites it least is 4.11 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, Reddit ranks fourth.

What this means in practice

This is the platform where reading the average causes the most damage. On the model that leans on community content, Reddit sits among the top sources. On the most selective model, it does not appear at all over 13 months. Community work is therefore high variance: valuable where your buyers use conversational and community driven assistants, close to worthless where they use analytical ones. It is also the source you control least, which argues for participation rather than promotion.

How to use this study

1. Check the two subreddits where your category is discussed and make sure the factual claims about you are correct.
2. Answer as a practitioner rather than as a brand: promotional threads rarely become the version that gets cited.
3. Do not build your whole plan on it if your buyers use the model that never cites it.

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.
