Seven AI platforms now handle enough search and recommendation queries to affect your brand's revenue. Each platform has different citation behaviors, different user bases, and different optimization requirements. BrandCited monitors all seven so you can see the complete picture of your AI visibility and prioritize platform-specific improvements.
1. ChatGPT (OpenAI)#
ChatGPT is the largest consumer AI platform with over 900 million weekly active users. It handles everything from product recommendations to research queries to code generation. For brand visibility, ChatGPT matters because of sheer volume. More users means more opportunities for your brand to be mentioned or missed.
Citation behavior: ChatGPT draws from both pre-trained knowledge and real-time web browsing. It tends to cite well-known brands with strong entity presence. Newer or smaller brands need to build their web footprint aggressively to appear in ChatGPT responses.
Optimization focus: Entity clarity, structured data, and content freshness. Make sure ChatGPT can describe your brand accurately when asked directly.
2. Claude (Anthropic)#
Claude has carved out a strong position in professional and enterprise contexts. Business users, researchers, and developers use Claude for analysis, writing, and problem-solving. If your audience includes professionals making purchase decisions, Claude matters.
Citation behavior: Claude tends to be more cautious with brand recommendations, often qualifying citations with caveats. It weights factual accuracy and avoids promotional language. Content that reads like a sales pitch is less likely to be cited.
Optimization focus: Authoritative, factual content with clear data points. Claude rewards depth over breadth.
3. Gemini (Google)#
Gemini powers Google's AI Overviews, which now appear in 47% of Google searches. This makes Gemini the most consequential platform for search visibility. When a user searches Google and sees an AI Overview, Gemini decides which brands and sources to reference.
Citation behavior: Gemini leans heavily on Google's Knowledge Graph and Search index. Strong traditional SEO performance helps. Gemini also uses structured data more actively than other platforms.
Optimization focus: Schema markup (especially Organization, Product, and FAQ), Google Business Profile, and traditional SEO signals. Gemini rewards brands that already perform well in Google's ecosystem.
4. Perplexity#
Perplexity is the leading AI-native search engine. Users come specifically to find answers, making it a high-intent platform. Perplexity cites its sources explicitly with numbered references, making it the most transparent AI platform for brand attribution.

Citation behavior: Perplexity pulls from recent web content via real-time search. It favors pages with clear structure, specific data points, and authoritative sourcing. Unlike ChatGPT, Perplexity always shows its sources, so users can click through to your site.
Optimization focus: Content freshness, clear page structure, and source authority. Perplexity is the platform where traditional SEO and GEO overlap the most.
5. Grok (xAI)#
Grok is integrated into X (formerly Twitter) and available as a standalone app. Its user base skews toward tech-savvy early adopters, news consumers, and people active on social media. For brands targeting these demographics, Grok is worth monitoring.
Citation behavior: Grok draws from X posts and web content. It has access to real-time social media data, so brands with strong X presence get cited more often. Grok also tends to be less filtered than other models, making it more likely to mention emerging brands.
Optimization focus: Active X/social media presence combined with strong web content. Grok rewards brands that participate in real-time conversations.
6. DeepSeek#
DeepSeek has gained significant traction in technical and research-oriented queries. Developers, engineers, and researchers use it for detailed technical questions. If your product targets technical audiences, DeepSeek visibility matters.
Citation behavior: DeepSeek favors technically detailed content with specific data, code examples, and research references. Marketing-oriented content rarely gets cited. Documentation, technical guides, and research papers perform well.
Optimization focus: Technical documentation, developer guides, and research-grade content with specific metrics and methodologies.
Meta's Llama powers AI features across Facebook, Instagram, WhatsApp, and Messenger. This gives it the largest potential reach for consumer-facing brands. When a Facebook user asks the AI assistant for a restaurant recommendation or a product suggestion, Llama handles the response.
Citation behavior: Llama's citation behavior is less transparent than other platforms since it operates within Meta's walled garden. Brand mentions tend to favor businesses with strong Facebook/Instagram profiles and active social engagement.
Optimization focus: Meta business profiles, active social media presence, and consumer-oriented content. Llama is the platform where social signals matter most.
No single optimization strategy works equally well across all seven platforms. A brand that performs well on Perplexity (which rewards fresh, structured content) might underperform on Claude (which rewards authoritative depth) or Llama (which rewards social presence).
BrandCited provides per-platform visibility scores so you can identify which platforms represent your biggest gaps and prioritize accordingly. Most brands start by fixing issues that affect all platforms (structured data, crawler access, entity clarity) before moving to platform-specific optimizations.
