1. Why AEO/GEO matters in Korea now
Search behavior in Korea is shifting fast. Alongside Google and Naver, more people — locals and expats alike — are asking ChatGPT, Claude, and Perplexity questions like "What's a good AEO agency in Korea?" and trusting whatever the AI recommends.
The problem: most brands, including well-established ones with strong Google rankings, simply don't exist in the AI's answer yet. Search ranking and AI mention are two different games. A business can rank #1 on Naver and still be invisible to ChatGPT.
Key point
AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) both refer to making AI models mention, cite, and recommend your brand when they answer relevant questions. The label "AI optimization" alone doesn't tell you whether an agency is actually doing this work or just rebranding standard SEO.
2. How it differs from traditional SEO
Many agencies in Korea now market "AI-era SEO" services that are, in practice, the same SEO work with a new label. Here's how to tell the difference.
| Aspect | Traditional SEO Agency | AEO/GEO Agency |
|---|---|---|
| Core metric | Search ranking position, click-through rate | AI mention rate, citation rate across models |
| What's measured | Google/Naver search result pages | Actual AI response text from ChatGPT, Claude, Gemini, Perplexity, etc. |
| How it's measured | Rank-tracking tools (easy to verify) | Repeatedly querying real AI models and reading the responses |
| Typical deliverable | Ranking change reports | Mention-rate trends by AI model, citation source analysis |
| Content strategy | Keyword density, backlinks | Structured data, entity consistency, citable factual content |
The biggest difference is how results are measured. Ranking is easy to check with any tool. Whether AI actually mentions you is only knowable by repeatedly querying multiple AI models and reading what they say — a step some agencies skip while still claiming "mention rate improved."
3. Five criteria to check
1. Do they provide a baseline measurement?
The first thing to ask is: "What's our current AI mention rate, right now?" Request a baseline report before signing. If they can't answer with real numbers, they're not actually measuring anything.
2. Do they track multiple AI models?
An agency checking only ChatGPT is very different from one tracking ChatGPT, Claude, Gemini, and Perplexity together. Each model cites different sources and shows different mention patterns — checking just one gives you a partial, potentially misleading picture.
3. Do they analyze citation sources?
AI models don't mention brands out of nowhere — they draw on something they've read or searched. An agency that can tell you which sites and pages the AI actually cited when it mentioned you (or a competitor) gives you a concrete basis for content strategy.
4. Can they actually publish content, not just report?
AEO/GEO doesn't stop at analysis. Once a mention gap is identified, someone needs to close it with real content (guides, FAQs, structured data). If analysis and execution are separate contracts, the whole process slows down.
5. Are they honest about what's realistic?
AI mention is slower to shift than search rankings, and no agency can guarantee 100% coverage. An agency that explains your current state and a realistic timeline is more trustworthy than one making guaranteed promises.
4. Quote comparison checklist
Even under the same "AEO/GEO consulting" label, scope varies enormously between agencies. When you receive a quote, check whether it includes each of these:
| Item | What to confirm |
|---|---|
| Number of tracked questions | How many real customer questions are actually monitored (too few won't be representative) |
| AI models tracked | Does it go beyond ChatGPT to include Claude, Gemini, Perplexity, and local AI search? |
| Reporting frequency | One-time audit, or ongoing weekly/monthly trend tracking? |
| Citation source analysis | Do they show specifically which sites got cited? |
| Content production | Analysis only, or actual content creation and publishing included? |
| Contract terms | Minimum commitment period and early termination conditions |
⚠️ Watch out
A quote that bundles everything under one vague "AI optimization package" line item makes it hard to know what's actually included. Make sure each item above is listed separately.

Because AEO/GEO is still an early-stage market with no fixed standards, watch for these warning signs.
✗ Red flag
They show you a single ChatGPT screenshot where your brand didn't appear, and present that one snapshot as proof of a problem.
Why it's a problem: A single query at a single moment isn't representative. AI responses vary run to run, so any real assessment requires repeated measurement.
✗ Red flag
They promise "100% mention guaranteed" or "#1 AI recommendation within one month."
Why it's a problem: AI mention isn't something you can buy outright like an ad slot. Content takes time to be reflected, and no one fully controls what any given AI model says.
✓ Trustworthy signal
"Your current mention rate is 2%. We'll re-measure in 4 weeks after publishing new content and compare the trend."
Why it matters: Not hiding a low starting number, and framing the engagement around trend comparison, is characteristic of measurement-based consulting.
6. Signs of a trustworthy agency
On the flip side, these behaviors suggest an agency genuinely understands and executes AEO/GEO work.
- They show weekly mention-rate trends — not a single snapshot, but change over time in a graph or table.
- They connect content publication to mention changes — showing data like "mentions in Perplexity started after this article went live."
- They show competitive share of voice — where you stand relative to competitors in AI mentions, not just your own numbers in isolation.
- They explain differences between AI models — "ChatGPT still doesn't mention you, but Perplexity started citing you last week," for example.
- They connect AI mentions to real site visits — showing whether AI mentions actually translate into traffic is the strongest signal of credibility.
7. Final checklist before you sign
| Item | What to confirm |
|---|---|
| Baseline report | Do they show a real, measured mention rate before you sign? |
| Number of models tracked | Do they track multiple AI models, not just one? |
| Citation source analysis | Do they specify which sites got cited? |
| Ongoing tracking | Is it a recurring weekly/monthly trend, not a one-time audit? |
| Content execution | Does the scope include actual content publishing, not just analysis? |
| Realistic timelines | Do they explain a realistic timeframe instead of promising instant, guaranteed results? |
| Contract terms | Are minimum commitment period and cancellation terms clearly stated? |
8. Frequently asked questions
What is the difference between an SEO agency and an AEO/GEO agency in Korea?
An SEO agency optimizes for ranking position on Google and Naver search results pages. An AEO/GEO agency optimizes for whether generative AI models like ChatGPT, Claude, and Perplexity actually mention and recommend your brand in their answers. The measurement methods are fundamentally different, so an agency that only shows you ranking reports is likely not measuring AEO/GEO at all.
How can I verify an AEO/GEO agency's claims before signing a contract?
Ask for a baseline report before you sign — a real measurement of how often your brand currently appears across multiple AI models for questions your customers actually ask. If an agency cannot produce this, they are likely guessing rather than measuring.
How long does it take to see results from AEO/GEO optimization in Korea?
AI mention rates typically take several weeks to a few months to shift after new content is published, since AI models need time to crawl, index, and surface new sources. Be skeptical of any agency promising guaranteed top mentions within days or weeks.
