THIRD PLAN · 서드플랜

Generative Engine Optimization (GEO) & AEO Agency in Korea

You have tried it twice. The third plan is calculated.

THIRD PLAN lists what is holding your business back, writes a guide for where it should go, and plans the marketing strategy that follows. The goal is a brand that ChatGPT and Gemini recommend.

Service 01

GEO Consulting: Diagnose, Guide, Strategy

Generative engine optimization (GEO) is the work of preparing a site and its content so that generative AI such as ChatGPT, Gemini and Perplexity cites the site and names the company in its answers.

We list the problems in your current marketing, write a guide for where the business should go, and plan the marketing strategy. The diagnosis covers search volume by category name, whether ChatGPT and Gemini run a web search for your questions, the fan-out searches they run, Google rankings for those searches, your homepage title, description, H1 and menu, your English pages, your static HTML, and robots.txt.

Self-description

Your category name, word for word, in the homepage title, description, H1 and menu.

02

English pages

An /en/ home linked to the Korean pages with hreflang.

One article per query cluster

We group fan-out searches by meaning and write one article per group: lead search term at the start of the title, the answer in the first paragraph, numbers, sources and quotes in the body.

04

Monthly re-measurement

The same questions, asked the same way every month, compared with the month before.

Specifically, our top-performing methods, Cite Sources, Quotation Addition, and Statistics Addition, achieved a relative improvement of 30-40% on the Position-Adjusted Word Count metric and 15-30% on the Subjective Impression metric.

Process

How we work: 6 steps

Every project follows the same order. Each decision rests on a measurement.

  1. 01

    Search volume by category name

    We check monthly Naver and Google search volume for each way of naming your business, and pick the name to lead with.

  2. 02

    Query fan-out collection

    We ask ChatGPT and Gemini the same questions several times and collect the searches they run while writing the answer.

  3. 03

    Question-by-question table

    For each question we record whether a web search ran, which sites were cited, and how often your name appeared.

  4. 04

    Self-description

    We put your category name, word for word, in the homepage title, description, H1 and menu, and build an English page.

  5. 05

    One article per query cluster

    We group searches that mean the same thing and write one article per group. The title starts with the group’s lead search term.

  6. 06

    Monthly re-measurement

    Every month we ask the same questions the same way and compare how often, and in what order, your name appears.

Why we start with search: 4 quotes

AI answers can be built on top of web search. These are the original sentences.

Both AI Overviews and AI Mode may use a "query fan-out" technique — issuing multiple related searches across subtopics and data sources — to develop a response.
