Key Findings:
Quick listen: How ChatGPT is powering smarter, faster SEO strategies — in under 2 minutes.
88% of marketers now use AI daily, according to SurveyMonkey’s 2025 report.
Nearly 9 out of 10 marketing pros are counting on AI tools to get things done faster, smarter, and better.
This shows how automation is no longer a nice-to-have. It has become the default.
For brands and agencies facing high competition or tight resources, not capitalizing on AI efficiency now risks them lagging behind in speed and relevance.

But to truly do things better, these tools must give users the “why” behind the data, so they can actually turn insights into action.
To see which AI tools deliver on this promise, DesignRush analyzed two of the biggest AI tools, ChatGPT and Google Gemini, testing each against 30 real-world SEO questions.
In this breakdown, you’ll learn:
- Where ChatGPT outperformed Gemini in keyword strategy, content mapping, and client-ready communication
- How AI can improve funnel alignment and help you plan content that drives conversions
- Ways to use ChatGPT’s strengths to streamline SEO workflows and boost client outcomes
Overall, the results favored ChatGPT in how well it supported marketers, writers, and clients.
ChatGPT has grown from an internal research tool to one of the most widely used AI platforms in the world.
Developed by OpenAI and launched nearly three years ago, it has quickly grown as the dominant conversational AI chatbot with 330 million daily U.S. users.
It originated from WebGPT (based on GPT-3.5) and evolved into GPT‑4, GPT‑4o, o1, and o3 for increased precision and multi-modal capability.
“What I liked most is how ChatGPT made SEO feel simpler,” said Kliment Stamenkov, SEO Manager at DesignRush.
“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.”
ChatGPT Performs Strongest in Key SEO Functions
DesignRush tested ChatGPT and Gemini (Google’s LLM) across 30 hands-on SEO scenarios to measure their performance in five categories:
- SEO Fundamentals
- Keyword Strategy
- Content & Funnel Alignment
- Technical SEO
- AI Visibility & SEO’s Future
ChatGPT emerged as the better tool in keyword strategy, content SEO, and foundational client education, which are critical functions that marketers rely on daily.
ChatGPT Wins in Keyword Research and Strategy
We explored the following questions to determine which tool, ChatGPT or Gemini, can help professionals better when it comes to keyword research and strategy:
- What is keyword proximity?
- What’s the definition of a long-tail keyword?
- How do I find keywords for local SEO?
ChatGPT offered keyword suggestions that reflect real-world intent.
Its examples were detailed and targeted, showing greater awareness of how users search in context.
ChatGPT explained long-tail structure and proximity using accessible language and relevant scenarios, like “best running shoes for flat feet in winter” instead of generic phrases.
This approach is already producing results.
For example, footwear e-commerce retailer Rocky Brands used AI-assisted keyword strategies to realign their SEO content with buyer intent, contributing to:
- 30% lift in organic search revenue
- 13% increase in new users
- 74% year-over-year revenue growth
The brand improved its performance by focusing on long-tail and intent-based keywords that matched how users actually searched.
Verdict: Better for teaching keyword strategy and creating briefs.
ChatGPT turns keyword planning into a usable process, helping teams build briefs rooted in intent, not just volume.
What This Means for Agencies:
Think of ChatGPT as having a strategist in the room.
Use its intent-focused suggestions to shape briefs that actually match how people search.
Then bake these insights right into your content calendar so every piece has a clear goal and audience.
ChatGPT Maps Content to the Funnel More Effectively
Questions explored include:
- What’s the difference between content and copy?
- How do you optimize for search intent?
- How does content fit into the funnel?
ChatGPT aligned content formats with the buyer journey more clearly than Gemini.
It used product examples to illustrate how blogs, comparisons, and product pages serve different stages of the funnel (TOFU, MOFU, and BOFU).
Its explanation of content versus copywriting focused on function. Content informs, while copy converts.
Real-world teams are seeing success by applying these insights. STACK Media, a fitness publishing brand, redesigned key landing pages using AI-assisted funnel planning.
Its new content structure helped deliver a 61% increase in website traffic and a 73% reduction in bounce rate.
It credited AI-supported topic targeting and funnel alignment for the performance.
Verdict: Ideal for content marketers and editorial leads optimizing for search intent.
For teams planning content calendars or optimizing existing assets, ChatGPT gives structure and purpose to every piece.
What This Means for Agencies
ChatGPT can help you map content aligned to the buyer journey in minutes instead of hours.
This means you can quickly show clients exactly how a blog, a product page, or a comparison article works together to move people closer to buying.
This kind of funnel-first planning is especially useful for client pitches.
ChatGPT Makes SEO Concepts Easier to Teach and Sell
Questions explored include:
- What is SEO?
- What are backlinks?
- What is link building, and why does it matter?
ChatGPT responded in a tone that works well for client education.
It explained backlinks as “votes of confidence” and gave real examples to illustrate value, something Gemini often skipped.
The conversational style reduced technical barriers, helping agencies and consultants explain SEO without overwhelming clients.
This clarity has helped professionals improve onboarding and client communication.
For instance, Sixth City Marketing used ChatGPT-style explanations and AI-powered content to support SEO training and onboarding.
One client saw a 543% increase in form submissions and an organic traffic gain of 632%.
This is largely due to more digestible content and messaging that clarified SEO value to stakeholders.
Verdict: Best for training and client-facing SEO communication.
Teaching SEO takes more than definitions. ChatGPT brings the clarity and tone needed for onboarding and client conversations.
What This Means for Agencies
Explaining SEO to clients can be a time sink.
ChatGPT’s simple, example-driven explanations can help you onboard new clients faster and keep them engaged.
Drop its plain-language SEO analogies into proposals, training decks, and even client emails to make your strategy easier to understand and sell.
ChatGPT Helps Produce SEO Content That Performs
Questions explored include:
- Can I use artificial intelligence (AI) for SEO content?
- Does content help SEO?
- How do you earn backlinks?
ChatGPT delivered usable blog ideas, structured outlines, and strategic formats.
Writers could integrate them directly into briefs or expand them into full pieces.
It produced content types that matter most for performance, all tailored to search behavior: FAQs, how-tos, and funnel-based posts.
Publishers like Bankrate.com have demonstrated the impact of scaling content with ChatGPT.
The team published over 160 AI-generated articles (with human editing), attracting more than 125,000 organic visitors per month.
These pieces now appear on Google’s first page for several competitive finance keywords, showing that structured, AI-assisted content can perform at a high level.
Verdict: Best for writers and strategists building high-performing, scalable SEO content.
Instead of just answering questions, ChatGPT shows how to build content around them with structure, voice, and purpose.
What This Means for Agencies
If you’re producing content at scale, ChatGPT can help you get from idea to first draft faster.
Use it to create blog outlines, FAQ lists, and how-to article frameworks that match search intent.
Your writers can then focus on adding the expertise and brand voice that make content perform, and keep clients coming back.
ChatGPT Gives Practical Guidance for AI-Era SEO Visibility
Questions explored include:
- How can my business show up in ChatGPT or Gemini answers?
- What’s the role of SEO in the AI era?
- How do we prove SEO’s value with all these AI tools around?
Gemini leaned heavily on Google’s technical framework, but struggled to translate this advantage into high-performing content.
On the other hand, ChatGPT focused on content tactics that work today, such as writing FAQs, earning backlinks from listicles, and building topic clusters.
It reinforced the value of expertise, experience, authority, and trustworthiness (E-E-A-T) for search credibility, especially in content summaries produced by AI models.
The Search Initiative helped a B2B client optimize informational content specifically for ChatGPT and AI-generated search features.
The client went from 0 to 90 indexed AI-related keywords and saw a 2,300% increase in traffic from AI-driven answers.
The team followed ChatGPT’s advice to structure content clearly, add FAQs, and emphasize credibility markers.
Verdict: ChatGPT turns AI visibility goals into actionable SEO strategies.
For content teams focused on discoverability in AI answers, ChatGPT provides practical steps that translate into real exposure.
What This Means for Agencies
AI-driven search is the new front page of Google.
ChatGPT can help you create content that shows up in AI answers, from structuring FAQs to building topic clusters.
Start folding these tactics into your client strategies now so you’re not playing catch-up when AI-driven visibility becomes the norm.
Where ChatGPT Doesn’t Dominate
ChatGPT excels at strategic and content-driven SEO tasks but falls short on Technical SEO (e.g., XML sitemaps, robots.txt, schema structure).
This is where Gemini holds an edge.
While ChatGPT is competent in explaining these concepts, Gemini’s output was more precise in syntax and formatting.
If you’re doing site audits, server log analysis, or deep technical markup, use Gemini or another SEO crawler.
For content and SEO teams, the best tools is the one that speeds up strategy, supports clear communication, and delivers results clients can understand.
In DesignRush’s testing, ChatGPT consistently did that across core SEO tasks.
It proved especially helpful for teams writing briefs, building content, and educating clients, where clarity and speed matter more than syntax.
With a saturation of AI tools, the edge goes to the one that actually fits how marketers work.
And today, that’s still ChatGPT.
AI tools can help you work faster, but these agencies make sure the strategy stays sharp and the results are easy for you to understand:
