According to Similarweb data, Reddit reached 1.7 billion monthly visits in late 2025, making it one of the largest sources of user-generated content available to AI systems.
Why does community content outperform traditional sources?
Authentic user experiences
AI systems are trained to value authenticity and real-world experience. Reddit discussions provide:
- First-hand accounts rather than marketing copy
- Specific use cases with detailed context
- Honest pros and cons from actual users
- Recent information updated through ongoing discussions
Question-answer format alignment
Reddit’s structure maps directly to how people query AI assistants:
- Subreddit topics match query categories
- Thread titles phrase exact user questions
- Top-voted answers represent community-validated information
- Comment depth provides nuanced perspectives
E-E-A-T signals in community content
Google’s E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) increasingly applies to AI citations. According to Google’s Search Quality Evaluator Guidelines, experience signals have become more important, and Reddit excels at providing them.
How do source categories rank for AI citations?
Rather than individual domains, source categories show clearer patterns:
| Source Category | Citation Share | Primary Platforms |
|---|---|---|
| Community platforms (Reddit, forums) | 25-30% | Grok, Perplexity |
| Professional networks (LinkedIn) | 8-12% | Google AI Mode, Perplexity |
| Official documentation | 10-15% | Mistral, DeepSeek |
| Video platforms (YouTube) | 5-10% | Google AI Overview |
| News and industry publications | 8-12% | All platforms |
Community platforms capture the largest share of citations across high-citation LLMs.
Which Reddit content gets cited most?
Reddit citations follow specific patterns. Our analysis shows:
- Discussion threads (reddit.com/r/[subreddit]/comments/…) account for 78% of citations
- Subreddit homepages appear in 15% of citations
- User profiles rarely get cited (less than 1%)
This confirms AI systems value specific discussion content over general Reddit presence.

Building authentic Reddit presence
The key is authentic participation, not promotional content:
