Which Korean GEO tools are free?

Among Korean GEO tools with a published free scope, RanketAI offers site and page structure checks without login, and after login 3 brand visibility analyses, brand recommendation opportunities and 1 competitor comparison for free. Other tools differ — some take a free audit request and reply by email — so compare on free scope and number of engines.

How far can I go without logging in?

Site Check and Page Structure Check work without login, up to 3 per day per IP. After login you can try 3 brand visibility analyses, brand recommendation opportunities (3 questions, 1 analysis) and 1 competitor comparison for free.

Isn't ChatGPT alone enough?

Engines differ. In the August 2026 benchmark the same 12 brands had mention rates of ChatGPT 33% · Gemini 83% · Perplexity 92%. Unless you know which AI your customers use, watch at least two.

What's the difference between Site Check and brand visibility analysis?

Site Check asks "can AI read and cite my site?" (the cause); brand visibility analysis asks "does my brand actually appear in AI answers?" (the result). If the result is poor, apply the cause-side recommendations first.

Can I compare against competitors?

Competitor Compare runs the same question set for competitor brands and shows mention rank and share side by side. The free tier is 1 competitor, 1 run; paid plans add competitors and repeat measurement.

On almost no budget, should I pick a GEO tool or consulting?

If you can fix content in-house, start with a tool. Within the free scope, fix structure issues via Site Check then Page Structure Check, confirm exposure with 3 brand visibility runs, then use brand recommendation opportunities to fill the questions you miss. When you need re-measurement and monitoring, look at Starter (₩12,900/month); consider consulting when you lack hands to execute.

My brand doesn't show up in ChatGPT answers — how do I check?

Register your brand name and domain in AI Brand Visibility Analysis and run it: you get a grade per engine — ChatGPT, Gemini, Perplexity — showing whether the brand is mentioned and whether your site is cited as a source. It separates "mentioned but not cited" from "not on the candidate list at all", with an improvement guide for each case. 3 free runs after login.

Citations in AI answers suddenly dropped — how do I find the cause?

Start with Site Check to confirm AI bot access (robots, llms.txt) and that nothing structural changed, then re-run brand visibility analysis to narrow which engine dropped you. The dashboard's citation history and Competitor Compare show whether a competitor took the spot. The step-by-step checklist is covered in the citation-drop diagnosis guide.

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

Criteria

How to compare diagnostic tools

Check these four first, whichever tool you pick

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.

Number of engines

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

Structure plus exposure

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

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.

Improvement loop

After the check — the improvement loop

How a check leads to improvement and re-measurement
