Must Read If Your Company Needs a GEO Assessment! GEO Checklist for Marketers

The domestic search market, which was once dominated by Naver, is undergoing seismic shifts day by day. In August 2026, the Google app took the top spot among productivity apps, surpassing Naver by approximately 180,000 monthly active users (MAU)

The industry the spread of Google's AI model service Gemini and the strengthening of AI search have had an impact. The ChatGPT app is also showing an upward trend, ranking 7th in the number of productivity app users.

As we rapidly enter the era of AI search, an increasing number of in-house marketers are reporting the necessity of GEO to management. However, when it comes to actually explaining the current situation, it is difficult for non-experts to determine where to begin. Elifunt, which is building SEO and GEO results primarily for domestic B2B firms, compiled a checklist to help you diagnose your company's GEO performance.

A Comprehensive Summary of Basic Concepts to Know Before GEO Diagnosis

What is GEO?

GEO stands for Generative Engine Optimization. It refers to an optimization strategy designed to help generative AIs like ChatGPT, Gemini, Perplexity, and Copilot better understand and reference our brand and content when generating responses.

Are GEO and SEO different tasks?

Viewing GEO as a completely different task from SEO leads to misunderstandings. Google Search Center also explains the AI ​​capabilities of search by stating that existing SEO best practices remain valid and that there are no separate, special optimization requirements to gain exposure to AI features. that crawlable pages, helpful content that users can read, important information provided in text, and structured data that aligns with the page contentare still important.

If I do SEO well, will GEO happen automatically?

That is not the case. If SEO is the foundation that enables search engines to discover and evaluate pages, GEO is a perspective that builds upon that foundation to help generative AI understand “what problem this brand solves,” “in what context it is trustworthy,” and “what questions it can be a candidate for answering.

For example, if a website has service pages but the actual questions customers ask are not organized into FAQs, the AI ​​lacks sufficient material to reference for its answers. Similarly, if there are many blog posts but brand descriptions, customer case studies, and external references are scattered across different wordings, it is difficult for the AI ​​to consistently identify the entity. This is why accurate GEO diagnosis is necessary.

How should I diagnose GEO?

It is recommended to view GEO diagnosis by dividing it into two main areas: one is on-site, and the other is off-site.

On-site assets are assets that our brand manages directly. These are areas that a company can design and modify itself, such as websites, service pages, blogs, FAQs, customer cases, schema markup, and metadata. This area can be addressed relatively early because the person in charge has the authority, and improvements to page structure or content accumulate immediately.

Off-site refers to trust signals formed outside the brand. This includes press releases, contributions to external media, customer reviews, community mentions, social content, corporate information platforms, and partner content. Off-site is difficult for us to control directly. Instead, it serves as important material that enables AI to verify a brand's claims alongside external evidence.

GEO Diagnostic Checklist Presented by Elifunt

After reviewing the GEO calculator results, it is recommended to identify which areas are lacking based on the checklist below. This GEO checklist serves as a standard to quickly determine if your company is ready to start GEO. Rather than trying to complete every item at once, use it to identify currently empty areas and set priorities.

1. AI Accessibility

First, you must ensure that AI and search engines can read the key content of our website. Even if you have good content, it is difficult to use it as material for answers if crawlers cannot access it or if important information is hidden only behind JavaScript.

Key Checklist

• Is robots.txt unnecessarily blocking access by major search and AI crawlers?
• Is your core content confined only to logins, popups, and text within images?
• Do the service description, pricing/implementation methods, FAQ, and customer case studies read as HTML text?
• Are key pages easily discovered through sitemaps and internal links?

At this stage, you should prioritize whether “important information is read on the public web” over technical completeness. This is because the information AI can reference ultimately originates from accessible information.

2. Structured Data (Schema)

Structured data is an indicator that helps search engines and AI understand the meaning of a page more clearly. While the mere existence of a schema does not guarantee GEO performance, a schema that matches the page content serves as a foundation for organizing the brand and content.

According to the “GEO Roadmap Report ” published by Elifunt in June 2026, based on an analysis of 548 domestic companies, 53% of domestic corporate websites had not implemented any schema markup. Of course, it is difficult to achieve AI search performance with schema markup alone, but such technical elements can create synergy when combined with content elements.

Key Checklist

• Is basic information such as company name, URL, logo, contact details, and social channels organized in the Organization schema?
• Does the FAQPage schema match the questions and answers on the actual page?
• Is the Product or Service schema configured to match the visible text on the product/service page?
• Is the Article or BlogPosting schema applied to the Blog/Article page?
• Is the page hierarchy organized using the BreadcrumbList schema?

precautions to take when embedding structured data into a website. An incorrect schema can be more dangerous than having none at all. Including reviews, prices, or features in the schema that are not present on the page, or having FAQ content that differs from the actual body of the content, can damage trust. The standard for a schema is not to "put in more," but to "put in content that matches what is seen."

3. Metadata and Heading Structure

The H1, H2, and H3 structure is also important in GEO. This is because, just as humans need a table of contents for documents, AI needs clues to grasp the topic and logical flow of a page.

Key Checklist

• Does each page have only one H1, and does it clearly explain the topic of the page?
• Are H2 and H3 organized in a logical hierarchy?
• Are the key keywords naturally integrated into the title, heading, and body text?
• Are meta descriptions written uniquely for each page?
• Are different pages repeating the same title and description?

For example, a title that reveals the target audience and problem situation based on keywords, such as "Customer Onboarding Automation Solution for B2B SaaS Companies," is better than a page with only an H1 entry titled "Solution Introduction." prioritize clarity of information over the style of the copy .

4. Content Structure

Content that is easy for AI to quote generally has clear questions and answers. Rather than mixing all content into a single long text without a structure to distinguish the content, it is more advantageous to divide the answers into units based on the questions the reader is actually asking.

Key Checklist

• Is there a key summary or conclusion at the top of the page?
• Does a short and clear answer follow immediately after the question-type H2/H3?
• Are the main pages internally linked?
• Are there formats that are easy to use in answers, such as definitions, comparisons, checklists, FAQs, and examples?
• Are supporting evidence, such as sources, data, and customer cases, attached alongside your claims?

Elifunt believes that when creating and publishing content, simply publishing a large volume is not as important as prioritizing the design of context. It is necessary to differentiate the roles of AI-cited content, conversion content, and core content, and to ensure that there are no gaps in the necessary content for each stage of customer awareness.

5. Knowledge Graph and Brand Entity

A brand entity is a bundle of information that enables AI to understand our company as a distinct entity. The company name, representative, service name, industry, address, contact information, social channels, key products, and area of ​​expertise must be consistently linked to one another.

Key Checklist

• Are basic business information, such as Google Business Profile and Bing Business Profile, registered?
• Aren't the company descriptions on corporate information platforms like Saramin, JobKorea, and LinkedIn significantly different from each other?
• Are the company name, service name, representative name, and industry category used consistently across the web?
• Are key members or author information linked to the content?
• Is your industry one that requires signals from external entities such as Namuwiki, Wikipedia, and industry directories?

This does not mean that every company must create a wiki document immediately. What matters is whether AI can recognize the same company in the same context across multiple sites. If company introductions differ from site to site, it is difficult for AI to reliably link the brand's expertise and categories.

6. Reviews and Signals of Customer Trust

AI does not rely solely on the strengths brands claim themselves to possess. It also examines signals left by third parties, such as customer reviews, ratings, and mentions on external platforms. While public reviews may be scarce in the B2B sector, other forms of credibility can be established through customer case studies, interviews, partner mentions, and seminar reviews.

Key Checklist

• Are reviews accumulating on review channels or rating platforms suitable for your industry?
• Are customer cases organized around the problem, solution process, and results?
• Is there a recurring message in customer interviews or implementation case studies?
• Is company information being managed at external touchpoints, such as recruitment platforms, partner pages, and event pages?
• Are inaccurate or outdated reviews and descriptions being left unattended?

The absence of reviews does not mean you cannot conduct a GEO. However, if there are few external signals of trust, you need to organize customer cases, use cases, before-and-after changes, and FAQs more specifically within your website.

7. Community and Social Mentions

Communities and social media are areas that reveal the context in which a brand is discussed in the actual market. While not every company needs to be frequently mentioned in large communities, it is essential to monitor how brand or category stories circulate on the channels where target customers gather.

Key Checklist

• Are brand names or service categories being mentioned in major communities?
• Are questions and reviews being managed rather than being neglected?
• Is your company's perspective and expertise accumulating on your official LinkedIn page?
• Do you have explanatory content on industry-appropriate social channels such as YouTube and Instagram?
• Are the company descriptions on social media profiles and the messages on the website consistent?

B2B companies, in particular, should pay attention to LinkedIn and YouTube channels . This is because both are preferred sources for generative AI. When identifying expertise in a specific industry, AI refers to recurring mentions outside of official websites along with signals from person-based content that can build credibility.

8. PR and Media Exposure

The press and external media serve as an important basis for credibility in off-site GEO. However, rather than the number of press releases issued , 'what message,' 'in what context,' and 'which media outlets mentioned it' are more important.

Elifunt’s “GEO Roadmap Report,” approximately 70% of 548 domestic companies had at least one media mention through PR. However, 36% of those mentions were positive. For AI to use media exposure as a reliable basis, positive evaluations and context must be built together, going beyond mere exposure.

Key Checklist

• Have there been any press releases or mentions by external media within the last year?
• Is the brand featured not only in general newspapers but also in specialized industry media?
• Does the company description in the article match the current website message?
• Do you have citations, such as representatives, experts, or customer cases, to reinforce credibility?
• Do you have a landing page ready that links from an external article?

Furthermore, PR is less effective if it ends with one-off exposure. The brand entity becomes clearer when the message covered in the article extends to websites, blogs, customer case studies, and social content.

9. Performance Measurement System

The final area of ​​the GEO diagnosis is the 'measurement system.' It is difficult to determine the next course of action if you stop at simply looking at the screen that says 'mentioned by AI.' You must examine which questions were mentioned, which pages were cited, and whether the AI ​​traffic led to actual action.

Key Checklist

• Are you identifying AI traffic sources such as ChatGPT, Perplexity, and Gemini in GA4?
• Do you check which pages AI-acquired users visit and what actions they take?
• Are you regularly tracking brand mention prompts?
• Are the AI ​​citation page and the actual conversion page linked?
• Are conversion events such as consultation requests, material downloads, and inquiries set up?

A performance measurement system is essential for GEO to become a standard for marketing decision-making rather than just a buzzword. If AI has started mentioning your brand, the next step is to look at traffic and conversions. Conversely, if there are no mentions, simply return to the checklist to identify which assets are lacking.

Finding it difficult to diagnose your GEO on your own? Consult with Elifunt, a marketing firm for the AI ​​era

A GEO assessment is not a one-time check. This is because website structure, content strategy, external credibility signals, and performance measurement are interconnected. Therefore, rather than trying to establish a perfect GEO strategy from the start, it is better to first determine which stage your company is currently at.

A brand visible in AI search is not built overnight. However, knowing what is lacking today makes it much clearer what to build first this month. If you are a marketer looking to organize your priorities with experts based on your company's SEO and GEO analysis, consult with Elifunt.
