In 2025, the University of Toronto published a finding that would change GEO forever: AI Search services differ systematically in domain diversity, freshness, cross-language stability, and sensitivity to phrasing. In other words, what works on ChatGPT may fail on Gemini — and what ranks on Claude may be invisible on Copilot.
By 2026, platform-specific optimization has become essential. Brands that treat all AI platforms the same achieve an average Inclusion Rate of just 23%. Those that optimize for each platform's unique requirements average 78% inclusion across all five major platforms.
At UltraScout AI, we've built the industry's first Multi-Platform Optimization Engine, analyzing content against platform-specific requirements simultaneously and providing tailored recommendations for each.

1. The Toronto Research: Why Platforms Differ
The University of Toronto team analyzed millions of AI responses across ChatGPT, Gemini, and other platforms. Their key findings:
- Domain diversity varies by 3.2x: Some platforms cite a wider range of sources than others
- Freshness sensitivity differs by 47%: Gemini prioritizes recent content more than ChatGPT
- Cross-language stability varies: Performance across languages is inconsistent
- Phrasing sensitivity: Small wording changes affect some platforms more than others

🔥 High priority · 🟡 Medium priority · 🔻 Low priority (based on UltraScout platform analysis, 2026)
4. The Optimization Sweet Spot: Satisfying All Platforms
While each platform has unique preferences, there is an optimization sweet spot that satisfies all five simultaneously. Content that achieves this sweet spot averages 78% inclusion rate across all platforms.
Average inclusion rate for sweet-spot content
vs. 23% for generic content
The Sweet Spot Requirements:
- Entity authority: Complete schema.org markup with sameAs verification (satisfies all platforms)
- Multi-turn structure: H2 questions followed by concise answers, with deeper exploration (satisfies ChatGPT + AEO)
- Factual citations: Links to authoritative sources with clear attribution (satisfies Gemini + Perplexity)
- Balanced perspectives: Acknowledgment of alternative viewpoints (satisfies Claude)
- Actionable takeaways: Clear next steps or recommendations (satisfies Copilot)
- Freshness signals: Regular updates with "last updated" dates (satisfies Gemini)
📚 Research Finding
"62% of brands have technical architecture gaps causing AI citation rates 30% below industry average." — Alibaba Cloud, 2025
⚡ UltraScout Implementation
Our Sweet Spot Analyzer evaluates content against all five platform requirements simultaneously, identifying gaps and providing prioritized recommendations. Clients who achieve sweet-spot scores above 85 see 3.4x higher multi-platform inclusion.
5. Platform-Specific Case Study: DTC Mattress Brand
A leading DTC mattress brand came to UltraScout with strong SEO but minimal AI visibility. Our platform-specific analysis revealed:
- ChatGPT score: 23/100 — lacked conversational depth and multi-turn readiness
- Gemini score: 31/100 — missing structured data, low freshness
- Claude score: 45/100 — adequate but lacked balanced perspectives
- Copilot score: 18/100 — not action-oriented, missing commercial intent
- Perplexity score: 12/100 — minimal citations, low source diversity
After implementing our platform-specific recommendations:
Result: 78% average inclusion rate across all five platforms within 90 days.
6. The Multi-Platform Measurement Framework

7. Future Trends: Platform Convergence vs. Divergence
Will AI platforms become more similar or more distinct over time? Our analysis suggests:
- Short-term (2026-2027): Continued divergence as platforms differentiate for competitive advantage
- Medium-term (2028-2029): Partial convergence on core requirements (entity authority, structured data)
- Long-term (2030+): Persistent platform-specific preferences for tone, depth, and framing
The implication: platform-specific optimization will remain essential for the foreseeable future.
