When starting startup marketing, SEO and GEO optimization,, are key strategies for increasing ROAS (Return on Ad Spend). This is because it allows you to maximize long-term profitability by making customers seek out your brand without advertising costs.
However, for resource-constrained startups, it is difficult to design a direction on 'what to start with and how to prepare,' even while aware of the upcoming wave of GEO beyond SEO. This is because the areas requiring attention are vast, ranging from on-site aspects like websites to off-site aspects such as PR, and it is not easy to set priorities that lead to immediate results.
In this article, for labor-strapped startup marketers, Elifunt's recently published Based on data, I will summarize and introduce the key points of the Startup GEO Strategy Implementation Guide <GEO Roadmap 2026> 리포트
How is GEO marketing different from SEO?
GEO, or Generative Engine Optimization, a strategy that enables generative AI to understand and cite brands and content. If SEO (Search Engine Optimization) is the foundational work that allows search engines to find and evaluate our pages effectively, GEO is a perspective that extends that foundation to the AI response environment.
For example, when a customer asks the AI, “Tell me how to do GEO marketing for startups,” this content is cited as evidence to make the customer aware of Elifunt. This is exactly what GEO content marketing is.
Why should you take care of GEO when marketing a startup?
In the days before LLMs like ChatGPT, Perplexity, and Gemini existed, all you had to do was manage Google and Naver search results. You just had to find the keywords customers searched for frequently, write and distribute content that provided answers, and that was it.
However, customers are now asking generative AI questions directly. Market research firm Gartnertraditional search engine traffic would decrease by 25% by 2026.predicted that The OpenSurvey AI Search Trends Report 2026showed rapid progress, with the number of users who have used ChatGPT within the last three months rising by 15% compared to 2025.
As generative AI becomes a part of customers' daily lives, the market's understanding of GEO (Generative Engine Optimization),, is also rapidly increasing.
GEO Calculator: The Starting Point for GEO Marketing for Startup Marketers
The problem is that most startups have low brand awareness and absolutely minimal marketing activity, so thereis little data for AI to use as evidence. Even if supporting data is accumulated in the form of website and blog content, it may not be cited by AI because it consists of images that AI cannot read or has a structure that is not GEO-friendly.
To kickstart GEO marketing, startup marketers must first assess their brand's current status. In November 2025, Elifunt the GEO Calculator, which allows you to check your brand's SEO and GEO standing. You can diagnose for free what your brand is lacking from a GEO marketing perspective.
How should the GEO calculator results be interpreted?
Rather than looking at the total score alone, interpret it by separating it into on-site and off-site. On-site refers to elements that can be controlled within our website (content, site structure, etc.), while off-site refers to mentions or credibility from external channels (media coverage, external links, etc.).
If your on-site score is low , you should start by examining elements that can be resolved within your website, such as its information structure or content structure . This is because it could be a sign that the AI lacks the basic materials to understand your brand.
Conversely, if your on-site presence is well-established but your off-site score is low, youmust focus on building a foundation of external credibility through media coverage, mentions on communities, and social media. This is because it implies that while you possess good content, you are not yet sufficiently known or trusted externally.
Rather than focusing on the score itself, use the GEO calculator to accurately identify where the bottleneck is currently in your brand's GEO journey.
Domestic Marketing Channels for GEO: On-site and Off-site
On-site refers to in-house channels that a company can manage directly, such as websites or blogs. On the other hand, off-site refers to brand-related information accumulated by customers or third parties outside of the website. This includes reviews, communities, press coverage, and social media mentions.
Korean answers from ChatGPT, Perplexity, Claude, and others tend to heavily cite media outlets, Namuwiki, and Korean blogs . The major domestic off-site channels cited by AI in their answers are as follows:
When doing GEO marketing, should startups focus first on on-site or off-site?
On-site: You must build a solid internal foundation first
To start with the conclusion, startup marketing must be properly designed from the on-site stage. Based on GEO calculator data, Elifunt published in June 2026 <GEO Roadmap 2026> 리포트Looking at it, startups had an on-site GEO score of 56.9, whichwas similar to the overall average.
Upon closer inspection, the structure required for AI to understand and quote contentwas not in place. While content was being accumulated, the basics of SEO optimization, such as heading structure, were often overlooked, and the schema code score—structured data that helps AI read websites—was 32.6, which was even lower than the average.
If our website fails to serve as a data source that AI can read, its influence will inevitably weaken, no matter how frequently it is mentioned externally. First, you must clearly define how you want your service to be perceived by customers to create a brand entity and structure the entire website. Then, plan content based on potential customers' keywords and questions, and build your writing in a structure that is easy for search engines to understand.
👀 What is an Entity?
It is a term used to describe the most basic 'entities' through which search engines and AI understand the objects of the world. Google classifies our brands into four entities—people, places, organizations, and things—and constructs brand entities using extensive data.
Therefore, in the AI era, marketers must accumulate various types of information in the online world, such as structured data like knowledge graphs and websites, so that search engines and AI can fully understand information about our brands and form entities.

Once your internal foundation is solid, you can move on to the stage of building credibility by repeatedly exposing the same message to external channels such as the press, specialized media, partner content, LinkedIn, and YouTube.
To summarize, prepare on-site first, followed by gradually building up off-site capabilities. Of course, for startups that already have a well-established on-site foundation, securing a basis for external credibility will be a crucial key to future growth.
💡 Essential On-Site GEO Checklist for Startup Marketing
- Title Tag: Does the Title Tag of each page on the website contain the brand name and key keywords?
- Meta Description: Does the meta description clearly present the core services and targets?
- Heading Structure: Is the H1, H2, and H3 hierarchy logically organized?
- Schema Markup: Is the appropriate schema implemented on the website, such as Organization, Website, Product, FAQPage, Review, etc.?
- Content Structure: Is there enough content to answer customer questions, such as service introductions, FAQs, blogs, and customer case studies?
Offsite: Start small and tailored to your industry
It is difficult to achieve results in the short term with off-site. <GEO Roadmap 2026> 리포트Even in this case, the average GEO calculator scores for startups and large corporations were 37 and 54, respectively, showing a difference of 17 points. The biggest factor creating this score difference was the off-site score.
Start by consistently organizing essential information online. This involves registering a business profile on search engines like Google and Bing, or setting the profiles on your social media accounts to a consistent language. If possible, also try registering information about your company and services on external channels like Namuwiki.
However, the information sources cited for potential customers' key questions may vary depending on the industry. For example, if your company's service is SaaS, corporate blog content or PR articles tend to be cited as primary sources for potential customer questions; conversely, for B2C industries such as hospitals, Google Maps reviews are more important. Try asking potential customers questions they might ask on major LLMs like ChatGPT and Perplexity, and then attempt marketing after identifying which resources are most likely to be cited in your industry.
💡 Essential Checklist for Off-Site GEO Startup Marketing
- Knowledge Graph: Is brand information registered in wiki articles such as Namuwiki and Wikipedia?
- Knowledge Graph: Are you listed on major business profiles such as Google and Bing?
- Knowledge Graph: Is information consistently listed on corporate information platforms such as Saramin, JobKorea, and Innovation Forest?
- Social: If you are a B2B company, do you have an official LinkedIn page?
- Social: Top AI citation platform, are you running a YouTube channel?
- Social: Do you regularly upload content to social channels such as Instagram?
- PR/Media: Have you had at least one press release or media exposure within the past year?
Is simply being exposed to AI the end of it? The performance of a GEO strategy must be 'revenue'
When establishing a GEO marketing strategy for a startup, there is a crucial point that must be considered: 'Can GEO marketing lead to sales?' Just like SEO content, GEO content not be merely informative writing, but rather a 'conversion asset' that answers customer questions and drives them toward their next action .
Therefore, a content strategy that stays true to the basics is more important than ever.

Frequently Asked Questions about Startup GEO Marketing
Q. Regarding SEO, I have only been publishing content on Naver Blog. What additional steps should I take?
While Naver Blog remains important in the domestic market, it has limitations from a GEO perspective. This is because AI search engines prefer proprietary websites and structured data. Therefore, I recommend publishing SEO and GEO-optimized content on your official website and utilizing Naver Blog as a channel to distribute or summarize that content.

While not strictly necessary, it can be helpful when setting internal priorities. This is especially important for startups with limited internal resources, and consulting can assist in clarifying 'which questions should be addressed first' before exploring every single channel.
