YouTube23.3%Nearly every industry
Wikipedia18.4%ChatGPT especially
Google.com16.4%Support/dev content

But platform-specific patterns differ dramatically:

  • ChatGPT: Wikipedia 7.8%, Reddit 1.8%
  • Perplexity: Reddit 6.6%, YouTube 2.0%
  • Google AI Overviews: Reddit 2.2%, YouTube 1.9%

The insight:

The platform divergence is real. Here’s how we approach it.

ChatGPT optimization (Wikipedia-heavy):

StrategyImpact
Wikipedia entry maintenanceHigh
Consistent entity informationHigh
Authoritative domain presenceMedium
Training data relevanceMedium

Perplexity optimization (Reddit-heavy):

StrategyImpact
Authentic Reddit engagementVery High
Real-time content freshnessHigh
Community presenceHigh
Clear source citationsMedium

The 11% overlap problem:

We’ve found that brands need BOTH strategies running in parallel. Focusing on one platform leaves you invisible on the other.

Our allocation:

  • 40% universal optimization (works everywhere)
  • 30% ChatGPT-specific (Wikipedia, authority)
  • 30% Perplexity-specific (Reddit, freshness)

Wikipedia strategy details that worked for us:

What we did:

  1. Created Wikipedia entry (met notability requirements)
  2. Added citations to industry publications
  3. Maintained consistent entity data
  4. Updated quarterly with new milestones

The result:

ChatGPT mentions went from 0 to regular citations within 3 months.

Key learning:

Wikipedia isn’t just about having an entry. It’s about:

  • Neutral, factual content
  • Strong external citations
  • Regular maintenance
  • Entity consistency with other platforms

Warning:

Don’t try to promote on Wikipedia. Editors catch it immediately. Keep it factual and let the authority build naturally.

The 6.6% Reddit citation rate for Perplexity is massive.

How we approach Reddit for AI visibility:

ApproachWorksDoesn’t Work
Genuine problem-solvingYesSelf-promotion
Sharing real experienceYesGeneric advice
Data-backed insightsYesVague claims
Engaging authenticallyYesOne-time posts

Our Reddit presence strategy:

  • Identify 5-10 relevant subreddits
  • Contribute genuinely for 3+ months before mentioning brand
  • Share real data, not marketing claims
  • Answer questions with personal experience

The timeline:

Month 1-3: Build karma and reputation Month 4-6: Occasional brand mentions when genuinely relevant Month 6+: AI citations start appearing

Warning:

Reddit communities detect and reject promotional content instantly. Authenticity isn’t optional.

YouTube_Analysis · January 9, 2026

YouTube at 23.3% surprised me. Here’s what we learned.

Why YouTube dominates:

  • Visual explanations for complex topics
  • Practical tutorials and how-tos
  • User-friendly format AI can reference
  • Closed captions provide text for AI

Industry breakdown:

IndustryYouTube Citation %
E-commerce32.4%
SEO39.1%
Finance23%
General23.3%

Our YouTube strategy:

  1. Create detailed tutorial content
  2. Optimize titles for question-based queries
  3. Add comprehensive descriptions
  4. Enable closed captions (AI reads these)
  5. Include timestamps for sections

The result:

YouTube videos started appearing in AI citations within 6 weeks of publishing. Faster than any other content type.

The domain type data is fascinating.

TLD citation breakdown:

TLDCitation %
.com80.41%
.org11.29%
.uk~1%
.io1.67%
.ai1.13%

What this means:

Commercial domains (.com) still dominate AI citations massively. But .io and .ai domains are punching above their weight in tech verticals.

Our observations:

  • Traditional authority still matters
  • Newer TLDs work if content is strong
  • .org domains do well for educational content
  • Country TLDs are underrepresented globally

Recommendation:

Don’t switch domains for AI visibility. Focus on content quality and authority signals instead.
