To understand the core distinctions between these leading AI models, here's a quick comparison of their key features:

Prompt Testing and Examples: ChatGPT vs. Gemini vs. Claude

To evaluate their real-world performance, the chatbots were tested with a series of prompts across various domains.

Prompt 1: What Are The Top 3 Technical SEO Factors I Can Use To Optimize My Site?

ChatGPT's Response

ChatGPT delivered a coherent and well-structured response, identifying three crucial areas for technical SEO optimization:

• Site speed
• Crawlability and indexability

When prompted for more detail on site speed, ChatGPT provided extensive information, including methods to test and monitor performance (listing four tools), optimization techniques (image optimization, CDN usage, caching, code minification), and advanced developer-focused optimizations like preloading and fetching resources. Its thoroughness, including the ability to generate a step-by-step checklist, was impressive.

Gemini's Response

Gemini's responses were notably fast and informative. It presented solid information, utilizing formatting, tables, and bold text for improved readability. Interestingly, Gemini suggested using Google Search Console as the best tool for auditing technical factors, particularly Core Web Vitals and indexing issues.

When asked for more information on "Site Speed & User Experience (Core Web Vitals)," Gemini provided an extensive explanation covering:

• Understanding Core Web Vitals (CWV): Detailed explanations of LCP, INP, and CLS, including their measurements, target scores, and consequences of poor performance.
• Why CWV is Essential for SEO: Four examples highlighting its importance for page experience, mobile-first indexing, bounce rate reduction, and conversion impact.

While Gemini offered good optimization recommendations, some were advanced and might require further prompting for average users to fully understand (e.g., minimizing main-thread work). Overall, ChatGPT's initial deep dive into site speed felt more comprehensive, whereas Gemini might require more iterative prompting for advanced topics.

Claude's Response

Claude's initial answers were solid, though they leaned more towards informative explanations rather than immediate actionable steps. While some tips were provided for each section, the primary focus appeared to be education. When probed further on "Page Speed & Core Web Vitals," Claude delivered an extensive response, recommending tools and quick wins like compression and next-gen image formats. However, it notably did not provide direct links to the recommended tools.

Winner: Both Claude and ChatGPT excelled with their extensive answers, offering specific tools and actionable steps. Gemini, while informative, shied away from recommending third-party tools, focusing instead on its own ecosystem.

Prompt 2: I Have a Small Dog. Can You Recommend 5 Dog Beds for Them?

This prompt aimed to test product recommendation capabilities, particularly ChatGPT's integrated shopping features.

ChatGPT's Response

ChatGPT began by outlining key considerations for choosing a small dog bed. Its response became particularly interesting with the shopping recommendations: it listed specific dog beds, allowed users to view pricing from multiple stores, and offered an integrated purchase option. This feature significantly enhanced the user experience for product-related queries.

Gemini's Response

Gemini's recommendations were a good middle ground between ChatGPT and Claude. It suggested real and suitable dog bed options but notably lacked direct product links. When asked why it didn't provide links, Gemini stated it couldn't, despite often linking sources for information queries. This suggests a potential future integration of agentic commerce, especially given Google's partnership with PayPal in this area.

Claude's Response

Claude's response was more basic, focusing on different types of dog beds rather than specific product recommendations. While useful for understanding bed categories, it didn't offer the direct shopping utility seen in ChatGPT. Claude's strength lies more in general coding, where it often outperforms ChatGPT.

Winner: ChatGPT clearly won this round due to its ability to provide product links and an integrated shopping experience. Gemini offered good recommendations but lacked direct purchase pathways, while Claude's response was too general for a shopping-focused query.

Prompt 3: I Want To Become An Authority In SEO. What Steps Should I Take To Reach This Goal?

This advanced prompt tested the chatbots' ability to provide comprehensive career guidance.

ChatGPT's Response

ChatGPT provided a robust and detailed response, outlining numerous steps to achieve SEO authority. Its recommendations included taking courses, gaining hands-on experience, and suggesting specific resources for staying updated on SEO news. The response was well-structured and offered a wealth of actionable advice.

Gemini's Response

Gemini also delivered an extensive list of recommendations, including suggestions for guest posting opportunities and useful SEO tools. While comprehensive, it could benefit from more explicit information on continuous learning within the initial response, though further probing would likely yield more details.

Claude's Response

Claude offered many valuable suggestions, notably mentioning various courses for learning SEO basics. It also included unique recommendations for complementary skills, such as data analysis and content strategy. While its advice was insightful, Claude's formatting was less polished compared to the other two, which could affect readability.

Overall, all three chatbots provided excellent guidance for aspiring SEO authorities, with ChatGPT and Gemini offering particularly well-formatted and in-depth recommendations.

Prompt 4: Create A Robots.txt File Where I Block Google Search Bot, Hide My "Private" Folder, And Block The Following IP Address "123.123.123.123"

This technical prompt tested the chatbots' understanding of web server configurations and limitations.

ChatGPT's Response

ChatGPT accurately processed the request, reiterated the instructions, and provided the correct robots.txt configuration. Crucially, it correctly identified that IP addresses cannot be blocked via robots.txt and then explained the proper method for blocking IPs using an .htaccess file. Its ability to provide accurate code and explain technical limitations was highly impressive, with improved code highlighting for clarity.

Gemini's Response

Gemini also performed well, providing a robots.txt file and explaining how to block IP addresses via .htaccess. However, a significant flaw was observed: its initial robots.txt snippet blocked *all* user agents by default, not just Googlebot as requested, which could inadvertently de-index an entire site. When prompted to block Bingbot instead, it correctly blocked only Bingbot, raising questions about potential biases or inconsistencies in its initial response.

Claude's Response

Claude delivered a strong response, providing the correct robots.txt configuration and, like ChatGPT, accurately explaining that IP addresses cannot be blocked within robots.txt, offering the .htaccess solution. Its explanation was clear and technically sound.

Winner: ChatGPT and Claude were the winners here for their technical accuracy and correct handling of the IP blocking limitation. Gemini's initial robots.txt output, which would have blocked all crawlers, was a critical error that highlights the importance of verifying AI-generated code.

Prompt 5: What Are The Top 3 Destinations In Italy To Visit, And What Should I Know Before Visiting Them?

This prompt assessed the chatbots' ability to provide travel recommendations and practical advice.

ChatGPT's Response

ChatGPT consistently recommended Rome, Florence, and Venice as top destinations. Its responses included key attractions and practical tips for visiting each city. A notable enhancement was its ability to recommend specific products, such as sunglasses, and provide direct links for viewing and purchasing them, making the travel planning experience more integrated.

Gemini's Response

Gemini also performed very well, recommending the same top three destinations. It presented information in a clean, table-like format, offering tips on the best times to visit, dining, transportation, and what to wear. However, when asked about sunglasses, Gemini provided general tips and popular brands but, like with dog beds, did not offer direct product links, falling short of ChatGPT's integrated shopping experience.

Claude's Response

Claude's response was extensive, detailing attractions and offering helpful tips like learning basic Italian, validating train tickets, and being aware of afternoon shop closures. However, its formatting appeared to have regressed compared to previous versions, making the information less scannable. For the sunglasses query, Claude offered general advice, some of which might be out of budget for many travelers, and did not provide product links. Overall, Claude's performance in this category felt less refined than in past iterations.

Winner: ChatGPT emerged as the winner for this query due to its seamless integration of product links, enhancing the shopping aspect of travel planning. Gemini was on par with ChatGPT for informational depth but lacked the direct product links, while Claude's formatting and product recommendations showed a noticeable regression.

Which Chatbot Is Better At This Stage?

Each of these powerful AI tools possesses distinct strengths and weaknesses, making the choice dependent on the specific task at hand.

Gemini has significantly improved, leveling the playing field with its polished UI and informative responses. It has the potential to integrate product links in the future, which would further enhance its utility.

Claude offers a highly polished experience, ideal for users seeking in-depth answers and detailed explanations, particularly for writing and coding tasks. However, it often lacks direct links to sources or products, even when web search is enabled, and its formatting can sometimes be less user-friendly.

ChatGPT currently holds an edge for shopping-related queries due to its integrated product links. Here's a summary of their optimal uses:

• ChatGPT: Best for everyday answers, product recommendations, voice chat, and general computer use.
• Gemini: Best for deep research and video generation.
• Claude: Best for writing and coding tasks.

The Reality of Hallucinations

It's crucial to remember that all chatbots can "hallucinate," producing convincing but factually incorrect information. Developers consistently warn users about this limitation. As ChatGPT advises, "ChatGPT can make mistakes. Consider checking important information." Similarly, Google states, "Gemini may display inaccurate information, including about people, so double-check its responses." Claude also cautions, "Claude can make mistakes. Please consider checking important information."

When using chatbots for tasks requiring factual accuracy or studies, always cross-reference the information. A recent study from February 2025 revealed that 91% of chatbot news responses contained problems, underscoring the need for verification. Real-world examples highlight the risks:

• An Alabama lawyer was removed from a case after ChatGPT generated fake legal citations.
• A man was hospitalized after following ChatGPT's advice to replace sodium chloride with sodium bromide in his diet.

These incidents serve as stark reminders that while chatbots learn from vast datasets, their accuracy is only as good as their training data and their ability to synthesize it without error. Always verify critical information.

Summary

ChatGPT, Gemini, and Claude are fascinating and rapidly evolving tools, but their long-term impact on publishers and users remains uncertain. While AI models might increase search activity, initial data suggests a decline in referrals from Large Language Models (LLMs) to external websites. Since July 2025, LLM referrals have reportedly decreased by 42.6%, posing a challenge for publishers and businesses hoping for AI-driven traffic.

As these technologies continue to develop, understanding their capabilities and limitations is paramount for both professionals and everyday users.
