Juggling AI tabs is a nightmare. You ask the same question to ChatGPT, Claude, and Gemini, hoping for a single, trustworthy answer. Which one is right? Which one is hallucinating?
At Search Umbrella, our platform is built to solve this. But we wanted to put it to the test with a real-world challenge. We ran a case study to see which large language model could best handle a professional content strategy task.
The outcome was not what we expected.
The Experiment: Crafting a Pro-Level SEO Outline
We created a prompt that mirrored a common, high-stakes business request. The goal was to test each AI on its understanding of Generative Engine Optimization (GEO) — essentially, the new frontier of SEO focused on optimizing content for AI-driven search results and conversational assistants.
"You are a senior SEO research analyst with 10 years experience helping small and medium sized businesses. Draft a 5-section SEO-focused blog post outline on ‘generative engine optimization (GEO)’, including proposed subheadings and target keywords."
The Contenders:
- GPT-4.1 (2025-04-14)
- Gemini 2.5 Pro
- Grok 4.0
- Perplexity Sonar Pro
The Verdict: Why Did Two AI Judges Choose a Surprise Winner?
To ensure a fair and expert evaluation, we appointed two impartial AI adjudicators: Cohere Command R Plus and Claude Sonnet 4. Their task was to score the four responses based on their quality, relevance to small businesses, and adherence to professional SEO and GEO best practices.
So, how did the judges score the contenders? The results were nearly identical—and they both picked a winner that surprised us.
In essence, both judges concluded that Grok 4 won not just by listing keywords, but by demonstrating a deeper understanding of user intent, topical authority, and practical business application—key pillars of modern Generative Engine Optimization.
From a human perspective Gemini 2.5 Pro did a great job but was eclipsed by Grok 4.
