What search method do you use when looking for necessary information? These days, the search process is hardly noticeable. This is because we have become accustomed to getting an immediate answer simply by opening generative AI tools like ChatGPT or Perflexity.

The 'zero-click' era has arrived, where you can get the desired answer instantly simply by entering a search term or prompt. Users now find the time spent browsing multiple websites on search engines to find results cumbersome.
Major search platforms are also responding swiftly to this. Google enables users to view desired answers directly on the search results page through 'Recommended Snippets' and 'AI Overview.' Naver is also planning to introduce 'AI Briefing' within the first quarter of 2025 to assist users with zero-click searches.


AI Search Engines, the New Standard for Content Distribution
Now, the success or failure of content marketing depends on whether it is chosen not only by people but also by AI. In an era where AI search is becoming the new standard for content distribution, this is why the Elifunt team emphasizes Generative Engine Optimization (GEO) content as much as Search Engine Optimization (SEO).
Generative Engine Optimization (GEO)
This is a strategy to optimize AI-based generative search engines to select specific content as a source when generating answers tailored to user questions.

Content marketing focusing on generative AI
Differences between SEO and GEO
While traditional SEO focused on ranking high on search results pages, GEO aims for content to be cited or recommended in AI-generated answers.
| division | Search Engine Optimization (SEO) | Generative AI Engine Optimization (GEO) |
|---|---|---|
| Exposure method | Search result link list | Quote within AI-generated answer |
| Key Indicators | Click-through rate (CTR) | Source citation frequency |
| Optimization target | Search engine crawler | LLM (Large-scale Language Model) |
Types of major AI search engines
AI search engines understand user intent to provide more accurate and personalized answers. Each engine has its own strengths, allowing for selective utilization based on the nature of the work or purpose.
| AI Search and Answer Engine | Developer | LLM | Characteristics (Strengths / Weaknesses) |
|---|---|---|---|
| ChatGPT | OpenAI | GPT-4 based | · Writing, coding, web search · Reflecting the latest information is somewhat slow |
| Claude | Anthropic | Claude 3.5 Sonnet | · Natural conversation, long document summaries, ethical responses · Low accuracy on some technical questions |
| Gemini | Google DeepMind | Gemini 2.0 | · Google Search integration, multimodal (text/image) analysis · Inconsistent response quality |
| Perplexity | Perplexity AI | PPLX and external models | · Provision of sources, search for the latest information, scalability as a portal · Somewhat lacking in creative work capabilities |
Perflexity's Entry into Korea: New Opportunities for GEO Marketing

Perplexitydreams of becoming a portal beyond a simple Q&A service. Last November in the U.S., it launched "Finance" and "Shopping" assistance features that provide real-time financial information. Perplexity's recent entry into the bidding war for TikTok is also due to its plans to expand into a portal.

Perflexity, a "rival to Google" in North America, made a full-scale entry into the Korean market in 2024. It has attracted investment from major Korean conglomerates such as SK Telecom and Samsung, and plans to establish its first Asian office in Korea. As competition for Perflexity optimization is not yet fierce in the domestic market, it is worth noting as a platform for GEO content marketing.
3 Content Writing Methods Chosen by AI Search Engines and a Checklist

If you search for 'GEO' on Perflexity, you can see that the Elifunt Team's content is cited. This is because we applied a systematic content strategy centered on quality, reliability, and structuring. Now, using marketing content creation as an example, I will introduce three ways to increase the likelihood of being cited by AI search engines.
1. Write content from the perspective of the person asking the question
👎 "Marketing Funnel Optimization Strategies" 👍 "How can we prevent customers from churn and lead them to a purchase?"
👎 "Digital Marketing Strategies" 👍 "How can startups conduct effective digital marketing with a limited budget?"
AI search engines excel at processing and responding to the language users use in their daily lives (natural language). Therefore, it is effective to write content using a user-centric question-and-answer structure. Organize your content by anticipating user questions and providing clear answers. If you have frequently asked questions, creating a separate FAQ page is also a good idea.
2. Providing specific data to increase reliability
👎 "Revenue increased significantly" 👍 "Revenue increased by 28% compared to Q4 2024"
👎 "Many users were satisfied" 👍 "89% positive response in user satisfaction survey"
AI search engines prefer high-quality content containing specific data over a simple list of information. Increase credibility by including specific dates, figures, and trend changes, and enhance the accuracy of your content by utilizing quotations and authoritative sources. It is particularly effective to use information updated within the last one to two years. For internal data, specify the research method and timeframe, and for external data, provide a link to the source.
3. Structure and organize information
Q: What is an effective way to acquire new customers?
A: The most effective method is 'utilizing existing customer reviews.'
Execution Steps: 1. Identify highly satisfied customers 2. Review writing events and rewards 3. Share reviews on social media/official website
Success Story: [Link]
Systematically organized information is more effective than long paragraphs. Present the key answer first, then include step-by-step implementation methods and specific examples.

As shown in the table above, using tables or diagrams can improve understanding when explaining complex concepts.
Continuous content updates are essential to increase the likelihood of being cited by Generative AI. It is also important to analyze the characteristics of cited sources to identify trends and reflect them. However, you must consider the value actually needed by customers before focusing on GEO strategies. An authentic approach toward customers is likely the most effective way to increase citations in AI search engines in the long run.
Checklist: Creating content that serves as the source for generative AI responses
☝🏻TIP: The goal is not to check every item on the checklist. Selectively apply the necessary items according to the purpose of the content and the audience.
1️⃣ Was it written from the reader's perspective?

Did you use an actual questioning tone, such as “What should I do?”
Have you organized frequently asked questions into a separate FAQ?
□ Do the reader's situation and concerns really come to life?
2️⃣ Did you present reliable data?
□ ⭐️ Did you include actual figures instead of vague expressions like “a lot” or “often”?
Did you use data from within the last 2 years?
□ Did you specify the source for internal data, such as “January 2024 Customer Survey Results”?
Have you included links to the original sources for external data?
3️⃣ Is it easy to read at a glance?
□ ⭐️ Did you summarize the important points or highlight them in bold?
□ ⭐️ Is the content neatly divided by section?
Do you reveal the main point first, like “The conclusion is…”?

Have you organized complex information into tables or charts?
4️⃣ Are you managing it consistently?
□ ⭐️ Are you regularly checking the status of your content?
Are you updating to reflect industry trends?
