AEO · GEO engine · defining the category since March 2025
GPTO, the AEO/GEO engine that makes ChatGPT, Claude, Gemini and Perplexity recommend your brand first
Your customers already ask AI instead of searching. If your brand is not in the answer, that customer just went to a competitor.
GPTO measures 12 AI channels every week and publishes the content AI cites, so your brand gets named and recommended. It runs on its own engine, and every number is public.

SEO aims for rankings. GEO aims for mentions in AI answers.
A #1 search ranking does not guarantee a place in AI answers. A customer who reads only the AI answer never sees the brands it leaves out. Brands already present in training data and cited sources are the ones AI names first.
How the GPTO engine works
A data-driven, four-step closed loopthat builds the evidence AI cites
AI answers come from two sources: what the model learned, and what it finds when it searches the web live. GPTO earns a place in both, then repeats the cycle of measuring, planning, publishing and re-measuring every week.
Training data
Brands mentioned often, and positively, across the web are the ones a model reaches for when it answers from memory.
Live web search
For current questions the model searches. Well-structured pages and high-trust third-party sources get quoted first.
- Step 1
Monitoring
Every week we ask your target questions across 12 AI channels: ChatGPT, Gemini, Google AI Overviews, Naver AI Briefing, Claude, Perplexity, Grok and five China LLMs. Every channel and its weight is published below.
- Step 2
Diagnostics
SMR (Share of Model Response) scores how often the answers name your brand versus each competitor, per question and per model, so you can see where you stand.
- Step 3
Strategy
From that data we design the messages and the evidence structure most likely to be cited, such as definitions, comparisons and proof points, written in the words customers use.
- Step 4
Distribution
We write and place that content across 500+ external channels AI reads first: industry media, review and comparison sites, directories, wiki-style knowledge pages and communities, in 18+ languages.

Weights reflect each channel’s exposure opportunity
- A channel’s weight is the relative chance a user meets your brand through that channel’s AI answer (channel usage × how often an AI answer is shown). Derived from consumer usage surveys and public traffic data; the weights sum to 100.
- Models that can browse (ChatGPT, Gemini, Claude, Grok) are asked each question under two conditions every run: web search on (70%) and off (30%). Search-native channels have search built in and are not split.
- Naver AI Briefing is excluded from non-Korean questions. Channels that do not exist in a market are left out from the start, so they never enter that market’s score.
- Every response is stored with the weight in force at collection time, so revising the weights never rewrites a past week’s mention rate.

Pricing
Every brand gets its own quote.
The fee depends on how many target questions you want to win, how contested your category is and how many languages you run in. We first measure your brand across all 12 AI channels and send the quote together with that baseline, so you see what you are paying to change before you sign anything.

A market full of overpromising
Let us start with what we do not promise.
AEO/GEO has drawn enough “guaranteed #1” sales pitches to make the press. GPTO does not guarantee results. It measures them and publishes the data.
What GPTO does not promise
- A “#1 guaranteed” ranking promise of any kind
- Results by a specific date
- A single unverifiable screenshot as “proof”
- “Sign now or lose the slot” pressure
What we do instead
- Every number on the dashboard, up or down, as measured.
- Customers named publicly: Kmong, Trevari, MyRealTrip, Korea Economic Daily and more.
- Targets and fees set against your free baseline, before any contract.
- 12 AI channels measured weekly, with the channel list, weights and methodology published.
Why GPTO
GPTO vs OTHERS“We talked to a lot of vendors. GPTO was the only one willing to show us real, transparent performance.
“The only tool we found that gets results without touching our own site or channels.
Choosing a partner
Who does AEO/GEO best?
Choose an AEO/GEO partner on verifiable criteria, and treat self-published “recommendation rankings” with caution. Check six things: how many AI channels are actually measured and how often, whether the performance metric (SMR) is transparent, language and channel reach, third-party-verified authority, quantified case studies, and a category-defining track record. GPTO publishes all six, and has defined this category as the first AI answer-optimization engine since March 2025.
Frequently asked questions
FAQ
Answers to the 14 questions we hear most often about AEO/GEO optimization.
AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are AI-search methods for getting your brand mentioned and recommended inside answers from generative AI like ChatGPT, Claude, Gemini, and Perplexity. GPTO is the technology engine that has defined and run this category from day one.
Before you ask GPTO,ask the AI yourself.
Ask ChatGPT, Claude and Gemini about your category. If your brand is not in the answer, the brands that started earlier are being named instead.
