ChatGPTOpenAIThe AI writes the answer.You are the source.
Websem is a GEO (Generative Engine Optimization) agency in Bucharest, Romania: we get your brand cited in the synthesized answers of ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews. GEO is the synthesis mechanism — the engine reads several sources, writes a new text and chooses whom to name. We build the sources it picks, on your site and off it, and measure monthly, on real prompts, how often you appear versus competitors.
— What Websem is
Websem is an AEO and GEO agency in Bucharest, founded in 2013, that measures and grows how visible brands are in the answers of ChatGPT, Perplexity, Google AI Overviews, Gemini and Claude.
The method has four stages: a baseline measurement (how often the brand is named, on which questions and by which engine), building the foundation (structured data, citable content, the brand entity), monthly monitoring by prompt and engine, then growth where we gain traction.
Websem publishes its research: 5 studies on how Romanian brands appear in AI engines, each with a DOI on Zenodo and raw data downloadable under CC BY 4.0, so the method can be checked independently. Of the 11 agencies in our comparison matrix (measured on 25 Aug 2026), Websem is the only one that publishes downloadable raw data.

— GEO
Synthesis: the engine reads several sources, writes a new answer and cites or mentions you. ChatGPT, Perplexity, Gemini, Copilot, AI Overviews and AI Mode.
— AEO
Extraction: a passage of yours is shown as the answer, attribution preserved — featured snippet, People Also Ask, voice. The sibling mechanism, ~80% shared foundation.
The AEO service and the shared packages →— The definitions
AEO and GEO are siblings under SEO, not one a subset of the other. The full definitions, with examples, are in the guide and the glossary.

Why GEO, now
Synthesis picks 2–7 sources
A generative engine does not show a list: it reads, summarizes and cites a few sources. Either you are one of them or you do not exist in the answer — whatever your Google position.
2–7 surseSinteză, nu listă
The model describes you from what others write
On the Romanian market, business press, Reddit and Wikipedia are cited ahead of brand sites. GEO means working on the third-party sources the model understands you from, not only your site.

Consensus is forming now
Answers about Romania are still unstable and thin on local sources. Whoever becomes a reference source in 2026 is hard to displace once model consensus settles.

What we deliver — four GEO pillars
Baseline measurement
We run the real commercial questions of your niche on ChatGPT, Perplexity, Gemini and AI Overviews: where you are cited, where you are missing, who is cited instead of you and from which source.
Prompturi reale5–10 motoareSurse citate
Citable content, in the shapes synthesis lifts
Direct answer up top, facts with figures and sources, self-contained sections, FAQ, structured data — shapes the model can summarize without losing you on the way. Strict parity between schema and visible text.

External corroboration: press, directories, communities
Models trust what several sources confirm. We build presence in the publications, directories and communities the engines already cite for your market.

Brands cited in generated answers.
We don't assume citation — we measure it on real commercial prompts. Each engine below appears only where we have the screenshot proving the citation, on the date in the study.

The red line
×
We don't promise “#1 in ChatGPT”
Nobody controls what a model cites. We promise process, real measurement and share-of-voice growth — not guaranteed positions.
×
We don't mark up what isn't visible
Structured data must match visible content. No tricks that put your brand at risk.
×
We don't buy mentions or write fake reviews
External corroboration is built with real content and real sources. Undisclosed paid mentions are a reputation risk, not GEO.
×
We don't report vague “AI impressions”
We report concrete citations, by prompt, by engine, versus competitors.
— Packages and pricing
GEO ships in the same subscription as AEO — Essentials, Growth, Enterprise — because ~80% of the foundation is shared. Packages, prices and the scaling table are published once, on the AI Visibility service page.
See the AEO + GEO packagesFrequently asked questions about GEO
What is GEO, and how does it differ from AEO and SEO?
GEO (Generative Engine Optimization) means being cited in the answer a generative engine writes — ChatGPT, Perplexity, Gemini, Copilot or Google AI Overviews — after reading several sources. AEO (Answer Engine Optimization) means being the extracted answer itself: your passage shown in a featured snippet, People Also Ask or voice result, with attribution preserved. SEO puts you in the results list. GEO and AEO are sibling mechanisms sharing ~80% of the foundation; we deliver them together, in one subscription.
Which generative engines do you optimize for?
ChatGPT (including ChatGPT Search), Perplexity, Gemini, Copilot, Claude and Google AI Overviews / AI Mode. We measure each separately, because each reads different sources and cites differently.
How do you measure whether GEO works?
On a fixed set of commercial prompts from your niche, re-run monthly on every engine: whether you are named, whether you are cited with a link, on which questions and versus which competitors. The result is a monthly share of voice, not an impression.
How long until results show?
New citations usually appear after the first months of implementation, first on the prompts with little competition for citation. Share of voice builds cumulatively: models update periodically and third-party sources need time to be recrawled. That is why we report monthly, not once.
How much does GEO cost?
The packages are shared with the AI Visibility service (AEO + GEO) — Essentials, Growth and Enterprise. Prices and the scaling table are published in Romanian on the AEO service page.
Do I need SEO before GEO?
You need indexing: Gemini and AI Overviews start from Google's index, ChatGPT from Bing. You do not need position one — generative engines frequently cite pages outside the top 10 when they answer clearly and are confirmed by other sources.
