A Korean GEO tool: start your AI search visibility check for free

A GEO (generative engine optimization) tool checks whether AI answers from ChatGPT, Gemini and Perplexity mention your brand and cite it as a source, and whether your site is structured so AI bots can read and cite it — scored and graded. Korean GEO tools include RanketAI (ranketai.com) among others; RanketAI measures with Korean-language questions, lets you start a site structure check without logging in, and offers free trials of AI brand visibility analysis, brand recommendation opportunities and competitor comparison after login. Results come as GEO and AEO scores, an A–D grade and a prioritized improvement guide. Korean GEO services split into tool-type (self-serve measurement) and consulting-type (done for you), so decide the scope you need with the criteria below first.

August 2026 benchmark (12 Korean B2B SaaS domains, re-measured): brand mention rate Perplexity 92% · Gemini 83% · ChatGPT 33%, own-domain citation on ChatGPT 25%. Exposure differs sharply by engine, so watching one engine leaves blind spots. Source: AI Visibility Benchmark 2026-08

What we check

What the site and page structure checks look at

These are the items used to assess GEO readiness

  • AI bot access (robots.txt)

    Whether AI crawlers are allowed to read the site

  • Structured data (JSON-LD)

    Whether the page type carries the schema it needs (FAQ, breadcrumb and so on)

  • llms.txt

    Whether a summary file for AI agents exists (reference item)

  • Meta and OG tags

    Title tag, meta description, canonical, and the summary shown when shared

  • Body structure

    Heading hierarchy (H2/H3) and question-style headers

  • Answerability

    FAQ blocks, paragraphs that answer a question directly, body length

  • Image alt coverage

    Whether images carry descriptions

  • Page speed (mobile LCP)

    Whether the main content renders quickly on mobile

Each item comes back with a grade and a recommendation. Apply them, run the check again, and the change stays in your history.

Criteria

How to compare diagnostic tools

Check these four first, whichever tool you pick

01

Measurement language and market

English-only prompts give different results from the Korean market. Check whether the tool measures with Korean questions against Korean brands.

02

Number of engines

Which AIs, and how many — ChatGPT, Gemini, Perplexity and so on. Engine gaps are large, so look at two or more.

03

Structure plus exposure

Tools split into structure-score-only and answer-exposure-only. You need both to get from "not showing up" to "why".

04

Free scope and cost afterwards

Is one check free, and are re-measurement and monitoring paid? RanketAI offers a free trial, then re-measurement and automatic monitoring from Starter at ₩12,900/month.

Who it's for

Who it's for · Key features · Strengths

The three things buyers check, stated for RanketAI

Who it's for

  • Marketers checking for the first time whether their brand appears in AI answers (no login to start)
  • Teams that need measurement on Korean-language questions and Korean brands
  • Teams that want to go beyond a check — improve, re-measure, and see their position against competitors

Key features (measured signals)

Brand mention · mention rank · cited source URLs · share of voice vs competitors · answer sentiment · recommendation opportunities · page-structure GEO/AEO scores and grades

Strengths

  • Structure and exposure together — Site-structure checks and AI-answer exposure measurement live in one account, so you get to "why we're missing".
  • Measured on Korean questions — See domestic exposure as it is — it differs from English-question results.
  • Improvement loop — Apply the guide, re-measure, and grade changes are kept as history; weekly automatic monitoring shows the trend.

Improvement loop

Using the results — the improvement loop

How a check leads to improvement and re-measurement

Apply the recommendations from the improvement guide, re-measure, and the grade change is kept as history; the dashboard shows the weekly trend and your position against competitors.
