Quick listen: ChatGPT vs Gemini, which AI knows SEO better? Hear what our experts found, in under 2 minutes.
Can AI really handle SEO like a pro?
With global SEO spend set to surpass $147 billion by 2025 and over 91% of marketers confirming its ROI, brands are doubling down on content, keywords, and discoverability.
At the same time, ChatGPT (800M+ users) and Gemini (400M MAUs) are reshaping how teams execute this strategy by automating briefs, audits, and even schema.
To understand how these AI tools actually perform, DesignRush ran 30 real-world SEO tasks through both models.
The prompts spanned five essential categories that reflect the full spectrum of what clients request, what strategists develop, and what teams are increasingly delegating to AI.
Our goal was simple: To find out where ChatGPT and Gemini help, where they fall short, and how smart teams can use them more effectively.
We grouped the 30 questions into 5 real-world SEO categories:
Each section measured how effectively the tools explained, applied, and contextualized SEO knowledge for real use cases.
These are foundational questions, ones clients or new team members ask first.
You want AI to explain clearly, with no jargon.
ChatGPT stood out here. Its tone is more natural, less robotic, and easier for non-SEOs to digest.
This is where most SEO strategies start.
If your AI tool can’t guide keyword thinking properly, it’s no help.
Mostly a tie, but ChatGPT had smoother explanations. Gemini leaned more instructional; ChatGPT leaned more conversational. ‘
AI tools are used to help draft blog content, site pages, landing pages, etc.
If they can’t understand intent, you’ll get fluff.
ChatGPT wins here again. Its answers reflected more awareness of audience needs, funnel stages, and real-world writing.
While most teams start with content, technical SEO still impacts indexing, site speed, and crawlability.
Gemini did better here. It was more direct and structured, which works well for technical breakdowns.
This is the new frontier. SEO teams are now thinking about how to appear in AI summaries, not just search results.
Both tools were helpful. Gemini leaned more into Google’s view, while ChatGPT gave better real-world tips.
From tone and teaching clarity to aligning content to user intent, ChatGPT edged out Gemini in most content-focused areas.
This is especially true in areas where the OpenAI platform needed to “think like an SEO,” not just recite facts.
Our in-house SEO team reviewed each AI response through the lens of real client needs, not just theoretical accuracy.
Their feedback reveals when each tool adds value and where human expertise is still essential.
“This study showed us we don’t need to pick one tool. We just need to know when to use each one.”
“AI tools like ChatGPT and Gemini are great at explaining SEO terms, but they can’t catch what a real strategist can — like broken schema, misused tags, or content gaps that matter.”
— Robin Fishley, SEO Director, DesignRush
“What I liked most is how ChatGPT made SEO feel simpler. It’s a big help for training or working with non-technical clients. But no matter the tool, we still need people to connect the dots.”
— Kliment Stamenkov, SEO Manager, DesignRush
AI tools like ChatGPT and Gemini can dramatically speed up SEO workflows, but they don’t replace critical thinking.
They generate faster, not smarter, and it’s still up to your team to steer the strategy.
Think of these tools as junior assistants. They’re helpful with drafts, research, and initial ideas, but they lack the depth to identify misaligned strategy, technical gaps, or business priorities.
Most importantly, clients don’t want summaries from a tool.
They trust experts who can translate data into action, make judgment calls, and connect SEO to real outcomes. Use AI to enhance your work, not define it.
“At the end of the day, the best SEO content comes from a real point of view.This is something no tool can fake,” Stamenkov added.
