Instead, it is whether your content infrastructure can get cited by ChatGPT, Perplexity, and Google AI Overviews.
This comparison of Relixir vs Sanity examines both platforms through the lens of Generative Engine Optimization. We will analyze their architecture, automation capabilities, and measurable GEO performance to help you make an informed decision.
Why Does GEO Now Dictate Your CMS Choice?
Over 1 billion people now use AI search every week to research products, compare solutions, and make purchasing decisions. This shift has fundamentally changed what content management systems need to deliver.
Traditional CMS platforms were built for a different era. They excel at storing and displaying content for human visitors. However, they lack the infrastructure for how large language models retrieve, understand, and cite information.
The gap between what traditional platforms offer and what AI search demands creates a critical business risk. "Answer Engine Optimization (AEO), also called Generative Engine Optimization (GEO), is the practice of structuring your content so AI language models like ChatGPT, Claude, Perplexity, and Google's AI Overviews can understand, cite, and feature your brand in their generated responses."
With Google AI Overviews expected to reach 75% coverage by 2028, the CMS you select today determines whether AI engines can efficiently parse, understand, and cite your content tomorrow.

What Makes a CMS Truly GEO-Native?
A GEO-native CMS delivers specific technical capabilities that traditional platforms lack. Based on IDC research on AI-enabled headless CMS platforms, here are the essential requirements:
Structured content collections: Content must live in organized, machine-readable formats that LLMs can easily parse and chunk
Short factual snippets: Pages need concise, quotable statements that AI can extract and cite directly
Automated JSON-LD schema: Structured data markup helps LLMs understand content semantics without manual configuration
Autonomous content refresh: LLMs heavily favor recent content. URLs updated within the last 30 days were 50% more likely to be cited by LLMs compared to those older than six months
Cross-platform citation tracking: Visibility monitoring across ChatGPT, Perplexity, Claude, Gemini, and other AI platforms
Recency bias optimization: Research shows that across seven major models, "fresh" passages can shift individual items by as many as 95 ranks in listwise reranking experiments
The distinction matters because content freshness directly impacts AI citations. Pages not updated in over a year are 2x more likely to lose citations to competitors.
How Does Sanity Perform on GEO Benchmarks?
Sanity is a headless CMS that stores content as structured JSON data in a cloud-based Content Lake. Founded in 2016 and headquartered in San Francisco, the platform employs 201-500 people and has earned a 4.5 overall rating from 271 reviews on Gartner Peer Insights.
Developer-Centric Flexibility & Collaboration
Sanity's core strength lies in its customization capabilities for development teams. The platform enables custom editing interfaces and content delivery to any platform via APIs.
"The real-time collaboration feature is something that has helped our team of developers and on-the-ground content experts," notes one Gartner reviewer.
Teams report cutting content management time by 60-70% when transitioning from multi-platform manual processes to Sanity's unified approach. Some organizations have seen deployment frequency increasing 300% after implementing the platform.
The Next.js integration is particularly praised, and Sanity Studio's open-source React foundation provides extensive customization options.
Where Sanity Falls Short for GEO
Despite its technical flexibility, Sanity presents significant limitations for teams prioritizing AI search visibility:
Developer dependency: The platform requires React and JavaScript expertise for setup and configuration. Content editors cannot launch projects without developer involvement
Learning curve: The proprietary GROQ query language adds complexity that delays time-to-value
No native GEO automation: Sanity provides the foundation for GEO but requires significant custom development to achieve automated citation optimization
Manual refresh cycles: The platform lacks autonomous content refresh capabilities, leaving teams to manually audit and update content
No AI visibility monitoring: There is no built-in tracking for how content performs across ChatGPT, Perplexity, or other AI platforms
As one Gartner reviewer noted: "I have a persistent feeling that the UI is not considerate of end users."
Key takeaway: Sanity is ideal for developer-led teams building highly customized digital experiences, but achieving GEO parity requires substantial engineering investment and third-party tooling.
