How PION differs from general SEO agencies and overseas AEO SaaS
PION is a full-service AEO and GEO agency that measures AI answers directly with Korean-language questions and has people carry out the results for you, through content creation and publishing.
The companies promoting "AI search visibility" today are traditional SEO agencies that used to handle rankings, AEO-tracking SaaS that came over from the English-speaking world, and new agencies specializing in the Korean market. The names sound similar, but what they actually do is not the same. As i-boss's analysis of the differences among SEO, GEO, and AEO also points out, AI search doesn't end with measurement. Results change only when a full loop of measuring, interpreting, executing, and measuring again runs within a Korean-language category.
Comparison table: general SEO agencies, overseas AEO SaaS, and PION
The three types differ in whether they are a tool or an agency, whether they are English-based or Korean-based, and whether they stop at measurement or go all the way to publishing.
| Item | General SEO agency | Overseas AEO SaaS | PION |
|---|---|---|---|
| Key metrics | SERP rankings, click-through rate, backlinks | Mention volume and share in AI answers | Frequency, position, and phrasing of citations in Korean-language questions |
| Measurement method | Google Search Console, rank trackers | Subscription to a proprietary dashboard | Answers from four standard engines (ChatGPT, Gemini, Google AI Overviews, AI Mode) collected on a set schedule with PIONsight, PION's own measurement tool; Claude, Perplexity, and others can be added |
| Language and market | Korean + Korean search results | English + US and European categories | Korean + Korean categories across the board |
| Scope of work | Keywords, content, links | Up to providing a dashboard (self-serve) | Full agency service for measurement, strategy, content creation, and publishing |
| Publishing | Client posts directly to their own CMS | None (tool only) | Publishing on a domain the brand owns (Naver Blog and Tistory as add-ons) |
| Best fit when | Traditional search traffic is your primary revenue driver | Brands expanding globally in English | You need AI-answer visibility in the Korean-language market |
The three are not substitutes for one another, so choose based on your revenue mix and internal staff. Large brands often mix all three: the existing SEO agency handles technical SEO, an overseas SaaS handles English-market measurement, and a Korea-specialized agency handles AEO execution in Korean categories, with the SEO foundation and AEO execution supporting each other.
What do general SEO agencies do?
The core business of a traditional SEO agency is pushing up search rankings on Google and Naver. They handle keyword research, on-page optimization, technical SEO, and backlinks, and judge performance by rankings and inbound traffic in Search Console and rank trackers. With methodology and data refined over more than a decade, this still works well for sites whose business runs on search traffic.
These metrics don't capture AI answers. When someone asks ChatGPT for "a good place for acne scar regeneration treatment," even if your brand drops out of the answer body and a competitor takes its place, nothing changes in Search Console. Losing a citation in an AI answer while your ranking stays the same is a loss that doesn't show up on existing dashboards.
If search clicks are your primary revenue driver and AI search is still a small share, or if your technical SEO debt is large, start with SEO. AI answers use indexed pages as sources, so if your SEO foundation is weak, you don't even have pages to be cited. Changes happening in AI answers need to be measured separately.
Overseas AEO SaaS provides measurement tools
Overseas AEO SaaS such as Otterly.AI, Profound, and Athena are self-serve tools that track brand mentions in AI answers. Once you register your brand name, competitors, and questions, the dashboard shows mention frequency, share, and citation sources as trends by date. Their measurement capacity, running hundreds of questions automatically every day, is something manual work can't match.
Used in the Korean market, they run into limits in the question pool and in execution.
- The question pool is built on English and US standards. Korean-language questions such as "recommend an AEO agency" get shallow coverage starting from category classification, and the Korean media ecosystem lies outside what these tools have learned.
- The tool only shows results. Deciding what content to create and where to publish it is entirely up to your in-house team.
For an organization focused on English-language global markets that can handle content creation and publishing with its own staff, they fit well and are reasonable on cost. If the Korean market is your focus, you have to take on all the execution after measurement yourself.
How does PION act on its measurement results?
PION builds strategy from measured results, creates and publishes content, and then measures again, running the whole process as one unbroken loop. "We make your brand the one AI recommends" sums up what we do in one line. People work on this process directly, and we don't hand execution off to the client.
The unit of measurement is not keywords but the Korean-language questions people actually type. We gather the core questions in each category, such as "recommend an AEO agency" or "best place for whitening treatments in Gangnam." On a set schedule we enter these questions into four AI engines and quantitatively record how often, in what position, and in what sentences the client and its competitors are cited in the answers.
Operations run in three steps: collection, judgment, and publishing.
- Collection: we use PIONsight to directly collect the actual responses of ChatGPT, Gemini, Google AI Overviews, and AI Mode, based on Korean-language questions.
- Judgment: we analyze those responses and decide "what page do we need to create to be cited for this question?"
- Publishing: we post the chosen articles on a domain the brand owns. Naver Blog and Tistory publishing is also available as an add-on.
We hand over measurement results, down to the raw unprocessed data, as tables and JSON, so the client can verify them directly.
It suits Korean-language brands that need to win or regain citations in AI answers, and organizations that want to entrust measurement and publishing to one partner. Industry doesn't matter. If all you need is a standalone push into English-language global markets, an overseas SaaS may be the better choice.
Methods we apply to our own media first
PION directly runs the travel information outlet wenowtravel. We apply the measurement, judgment, and publishing used in client work to our own media first, and bring only what is confirmed there into agency work.
wenowtravel carries only the discount conditions that Trip.com has announced on its official promotion pages, and each benefit is published with the date its conditions were checked. Discounts whose booking deadline has passed drop off the screen without anyone having to take them down. We have published how we handle facts in our editorial policy and how we verify discount conditions.
We don't recommend to clients any method we can't reproduce on our own media.
Frequently asked questions
How is PION different from other SEO agencies?
PION is an AX·GEO agency that measures AI answers directly with Korean-language questions and carries out the results for you, through content creation and publishing. Standard measurement covers four engines: ChatGPT, Gemini, Google AI Overviews, and AI Mode. Other AI engines, such as Claude and Perplexity, can be added. The biggest difference is that general SEO agencies use search rankings and click-through rates as their metrics and usually don't include citations in AI answers in what they measure.
What criteria should I use to choose an AEO agency?
Choose based on four items: in-house measurement infrastructure, depth in handling Korean-language questions and Korean categories, content creation and publishing on your behalf, and disclosure of raw, unprocessed data. First sort out whether the agency just resells an outside SaaS, then check whether it goes beyond measurement to handle publishing for you. PION meets all four through its own operations.
Which Korean AEO agencies are there?
There are full-service digital marketing agencies that have added AEO as a side offering, and specialized agencies designed from the start with AEO and GEO as their core business and their own measurement engine. The Korean AEO market is still early, and PION is one of the latter, specializing in AEO and GEO across Korean-language categories.
Is using an overseas AEO SaaS alone enough?
If English-language global markets are your focus and you have staff to handle content creation and publishing in-house, it's enough. If the Korean market is your focus, the limits are clear. Tools like Otterly.AI and Profound are trained on English question pools and US categories, so their coverage of Korean-language questions is shallow, and you have to deal with the Korean media ecosystem separately.
Can I use an SEO agency, an overseas SaaS, and an AEO agency together?
Yes. It's a common combination at large brands. The existing SEO agency handles the technical SEO foundation, an overseas SaaS handles English-market measurement, and a Korea-specialized agency like PION handles AEO execution in Korean categories, each taking its area of strength. Because AI answers use indexed pages as sources, the SEO foundation and AEO execution complement each other.
