If you've put real effort into getting your brand cited in ChatGPT, you're probably asking: does that work carry over to Claude and Gemini, or do I need to start from scratch on each platform? It's a good question. The answer is yes, mostly. There's roughly 80% overlap across the major AI search platforms. The rest of this post makes the case for why that's true, and what the remaining 20% tells us about where to actually focus your time.

Why the platforms are more alike than different

ChatGPT, Claude, Gemini, and Perplexity are all solving the same underlying problem: finding the most authoritative, trustworthy source to answer a user's query. That shared goal drives a lot of convergence in how they evaluate content.

All major LLMs are trained on broadly similar corpora of web content. When they pull live sources, they use retrieval-augmented generation (RAG) patterns that reward the same content signals. Analysis of how ChatGPT, Claude, and Gemini perform web searches shows that while their query strategies and citation behaviors differ at the margins, they're all pulling from the same web and applying similar filters for relevance and credibility.

Think of it like Google, Bing, and DuckDuckGo. Their algorithms are different. Their market shares are wildly different. But they all reward quality backlinks and authoritative content, because those signals genuinely correlate with what users want. The LLMs share a similar logic. Authority, clarity, and specificity are universally rewarded across platforms. That's the shared 80%.

Research into generative engine optimization supports this: GEO has identifiable principles that transfer across AI search platforms, rather than being a fragmented set of platform-specific tactics. The content quality signals that earn citations in one system tend to earn citations in others.

The real differentiator: long-tail queries, not platform tactics

Here's where I want to push back on how most people frame AI search optimization. The conversation tends to focus on platform differences, when the bigger lever is something else entirely: how specific your content is.

Traditional SEO was built around broad, high-volume keywords. You'd optimize a page for "time tracking software" and compete for that term across millions of searches. AI search doesn't work that way. Users ask LLMs detailed, conversational questions. They're not typing "time tracking software" into ChatGPT. They're asking "what's the best time tracking software for a small agency that bills by project?" That's a fundamentally different query, and it demands a fundamentally different content strategy.

Instead of targeting "time tracking software," you should be targeting "time tracking software for agencies with small teams." The latter is the kind of query an LLM will synthesize and cite a specific source for. Broad content gets passed over. Niche content gets cited.

LLMs are long-tail engines by nature. The users who turn to them are typically looking for something specific, not a general overview they could get from a quick Google search. The distinct web search behaviors of ChatGPT, Claude, and Gemini reflect this: each platform handles query specificity in its own way, but all three are responding to users who want precise, high-intent answers.

This is also why the long-tail strategy transfers across platforms. You're not optimizing for a platform's quirks. You're optimizing for a user behavior shift that's happening everywhere simultaneously.

What "authoritative content" actually means for AI

Authoritative is one of those words that gets used constantly and explained almost never. Let me be specific about what it means in an AI search context.

The content creation job has changed. It's no longer "write a good page about this topic." It's "what exact question will an LLM receive, and does my page answer it directly and completely?" That's the frame. If you're not starting from the query, you're starting from the wrong place.

Structurally, AI models parse content that's easy to read and extract. Clear headings, concise paragraphs, bullet points where appropriate, and FAQ schema all help. Geodde serves correct Schema for FAQ content precisely because that structured markup makes it easier for AI models to identify, parse, and cite your answers accurately.

The only real feedback loop is running your content against actual LLM prompts. Knowing how a platform responds to a specific query, with your content live, is the difference between guessing and knowing. Geodde runs prompts against ChatGPT for exactly this reason: to close the gap between publishing content and understanding whether it's actually being cited.

Technical hygiene matters too, site speed, mobile optimization, structured data, but treat those as table stakes. They're necessary, not differentiating.

Where the 20% divergence actually lives

I want to be honest about the differences, because that's what makes the 80% overlap claim credible rather than convenient.

ChatGPT, Claude, and Gemini do have distinct query strategies and citation behaviors. Perplexity operates differently again. These differences are real, and if you have the resources to optimize for each platform individually, there's marginal value in doing so.

The practical implication for most B2B SaaS marketing teams is this: build your content strategy on the shared 80% foundation first. Get your niche content publishing consistent. Get your structure right. Get your FAQ schema in place. Only then does it make sense to investigate platform-specific nuances.

For solo or two-person marketing teams who are already stretched thin, fragmenting your efforts across five separate platform playbooks is a reliable way to do none of them well. The 80% foundation is where the return actually is.

The marketers who will win in AI search

They won't be running five separate platform playbooks. They'll be the ones who understand their buyer's specific questions well enough to publish content that answers those questions with precision and clarity, consistently, over time.

B2B SaaS buyers are asking AI tools increasingly specific questions. The content strategy has to match that specificity. That's not a platform optimization problem. It's a content depth problem, and it's one that applies equally whether your buyer is using ChatGPT, Claude, Gemini, or whatever comes next.

Tools like Geodde, which helps B2B SaaS companies get cited in AI search platforms by publishing content AI models can easily synthesize and reference, exist to make this kind of consistent, AI-optimized publishing achievable for small teams without requiring a full content operation to run it.
