"How should we rebuild our website to do GEO well?" Cho Kyung-sang, CEO of NNT, hears this question every week. Nine out of ten companies that come to him for consulting open their first meeting with it, he says. And he flatly calls that approach "wrong." Not a different way of going about it — the wrong way.

GEO, or Generative Engine Optimization​, has become an unavoidable term in 2026 marketing-budget conversations. As ChatGPT's search feature, Perplexity, and Google's AI Overview begin to reshape how people look for information, companies are shifting part of their SEO budgets in this direction. The shift itself is a natural trend. The problem is that it's happening on a flawed premise. There's a clear reason why rebuilding your website won't make you show up better in AI search.

Why What Worked for Crawlers Doesn't Work for AI

SEO is built around how Google's crawler reads a web page. Meta tags, internal link structure, page-load speed, schema markup — these elements help Google's bot understand a page, and that understanding shapes search rankings. The logic the SEO industry has accumulated over nearly two decades is clear: structure your site so the crawler can read it well.

Ask the same question of GEO and it falls apart, for a reason — AI search works in a fundamentally different way. When Perplexity gets a query like "recommend a Korean marketing-automation tool," it searches the web in real time while simultaneously synthesizing learned patterns and external signals. In choosing which sources to cite, the AI's criterion is not "how accurate are this page's meta tags." It's "how trustworthy are this brand, this author, this source on this topic."

Rather than reading any one site's technical structure, AI looks at how a given brand or person is cited and mentioned across the internet as a whole. Has the name appeared in trade publications? Do other experts reference it? Have people cited that source when answering questions in the field? These are the traces that connect more directly to the AI's judgment.

If SEO is the work of announcing "I'm over here," GEO is the work of convincing someone that "I know this field." The party you have to convince has changed from a crawler to an AI. A crawler operates by rules; an AI selects on the basis of authority. That difference changes the entire approach.

Fixing your website isn't entirely pointless. Because AI search does draw on web crawling to some degree, basic technical optimization is still necessary. The point is simply that it shouldn't be the starting point of a GEO strategy. Before spending millions of won (several thousand dollars) on a website overhaul, there's a question to ask first: "Is there any reason for AI to see our brand as an authoritative source?"

Why You Can't Simply Be Optimistic About AI Search

Here we should pause on an honest question: is there really enough reason to focus on GEO right now?

The skeptical view is far from trivial. AI search delivers answers, but it often fails to generate clicks. Even when Perplexity or ChatGPT names a particular brand in an answer, analyses suggest that the rate at which users actually visit that site is markedly lower than the click-through rate on a Google search result. The SEO pathway, in which exposure translated directly into traffic, doesn't carry over to GEO.

Measurement is hard, too. There's no standardized tool yet — nothing like Google Search Console — that lets you see in numbers how often your brand gets referenced in AI search. Judging whether "GEO is working" is highly subjective. Some marketers dismiss GEO as "content marketing dressed up under a new name." If consistently producing good content works for AI, for Google, and for people alike, do we really need a separate frame called GEO? That criticism carries weight.

Even so, the direction the numbers are moving is too clear to ignore the channel entirely. Perplexity's monthly query volume passed hundreds of millions as of 2024, and companies are filing internal reports of shifts in traditional information-seeking patterns since ChatGPT added search. Surveys also show a rising share of B2B buyers turning to AI tools when they first research a vendor. It's hard to deny that AI search has begun to enter the mix as one of the routes to becoming known.

One thing to be clear about at this point: GEO does not replace SEO. They are channels to run in parallel, and their priority and weighting depend on your industry and target customer. For a small consumer-facing business, SEO on Google and Naver (Korea's dominant search portal) may still deliver more direct results. GEO is closer to long-term positioning work. It is not a channel to expect short-term conversions from.

What a Solo Operator Can Do Right Now

The fact that GEO hasn't fully settled yet makes now a less crowded moment, if anything. Large companies have started allocating GEO budgets, but their execution is still tangled in confusion. To say 90% are approaching it the wrong way is also to say that getting the direction right now means far less competition.

The first thing to check is your presence in outside media. AI treats content carried in trade publications, industry newsletters, and community contributions as far more authoritative than your own blog. Rather than posting more often on your own site, contributing articles to outside outlets, appearing in interviews, or making meaningful contributions in industry communities is more efficient from a GEO standpoint.

Creating information that exists nowhere else matters, too. The content AI cites tends to contain concrete numbers, original observation, or cases gathered firsthand. Recording what you have measured or experienced yourself — rather than summarizing what someone has already written — creates a reason to be cited. The field experience a solo operator holds is a scarce raw material in the AI-search environment.

Narrowing your subject area is also worth considering. AI tends to recognize a source that has consistently produced content on a specific topic as a voice in that field. Rather than covering many topics broadly, traces that accumulate deeply and steadily within a single area work in your favor.

Here's one practical check worth running. Search your own name, your brand, or the field you consider yourself an expert in on Perplexity or ChatGPT. If the AI doesn't know you, that's a signal that you currently leave no trace worth citing within the internet ecosystem. Deciding your next move after seeing that result is more productive than reaching first for a website-overhaul proposal.

Despite the impression the phrase "AI search marketing" gives, the starting point of this work is not technology. A single external trace worth citing comes before a single line of website code. Simply reversing that order puts you in a different place from most of the competitors standing at the same starting line.
