Glotier tells you whether ChatGPT, Gemini and Perplexity name your product when buyers ask what to use in your category. It puts your buyers' real questions to all three as live web queries, records whether you were named and by which of them, which competitors were named instead, and which pages each answer was built from.

How does Glotier check AI visibility?

It runs one live web search per question. ChatGPT and Gemini read the identical results, and Perplexity runs its own retrieval because it does not accept results handed to it. Whether your product is named is decided by a literal presence check on the answer text rather than by asking a model for its opinion, so the number cannot be inflated by a model being agreeable. You can also connect your own ChatGPT or Claude key and have the questions run through your account instead.

Why ask three assistants instead of one?

Because they disagree. In our own study of 40 buying questions, all three named the same product only 30% of the time, and 47% of products were named by exactly one assistant. Checking a single assistant shows you roughly 60% of what is being said about your category, so a founder who checks ChatGPT, sees their name and relaxes has measured one engine on one phrasing.

Is Glotier free to use?

The check is free with no signup. Paid plans start at $39/month (Solo), $99 (Studio) and $249 (Agency), and cover weekly tracking and the content the agent writes.

Does Glotier make up data about my product?

No. Every result comes from observed data: the live search results, the answers the assistants actually returned, and the sources they cited. It does not invent metrics, ratings or engine claims, and when a measurement has not run it says so rather than printing a zero.

Anyone selling something buyers research before choosing, where the category has enough alternatives that an assistant has to pick a shortlist: software, tools, e-commerce, and services. Founders, marketers and agencies all use it, and the work is the same at any size. It is not useful for local or in-person businesses, where maps and reviews decide the outcome instead.

What is the difference between GEO and SEO?

SEO is about your page ranking for a query. GEO is about your product being named inside an answer that an assistant assembles from several pages, most of which you do not own. The work overlaps heavily because a page has to rank to get retrieved, but the target and the measurement are different.

Is GEO replacing SEO?

No. GEO depends on SEO: an assistant retrieves pages via a live web search, so if nothing of yours or about you ranks, nothing of yours gets retrieved. It is better read as a new scoreboard on the same field than as a replacement sport.

What is the difference between GEO and AEO?

Very little in practice, and the distinction is mostly vocabulary. Answer engine optimisation usually refers to featured snippets and voice answers, generative engine optimisation to answers written by a model. Anyone drawing a hard line between them is usually selling one of them.

Do I need different tools for GEO?

You need one thing your rank tracker does not do: putting real buying questions to the assistants and recording which sources the answers were built from. Everything else you already have. That is why the honest version of this category is priced in tens of dollars a month rather than as a second Semrush.

Should I move budget from SEO to GEO?

Probably reallocate rather than move, and measure before you do either. One thing worth checking first: across 18 AI buying answers we read in full, review directories were 1 of 131 sources, 0.8%. If a directory listing is a line in your budget, that is the cheapest thing to test.

GEO vs SEO, and what actually differs

Most of the work is the same work. Three things genuinely differ, and they are the three that decide whether your existing effort translates.

The comparison, without the sales pitch

	SEO	GEO
What you are trying to win	A position on a results page for a query	A named place inside an answer somebody else assembled
Whose pages decide it	Mostly yours, judged against competing pages	Mostly other people's, retrieved for that one question
How you measure	Rank for a keyword, tracked over time	Named or not named, across a frozen set of buying questions
What a win pays	A click, usually	A recommendation, often without a click
Unit of work	Keywords, in the thousands	Buying questions, in the tens

GEO depends on SEO, which is why replacing it makes no sense

An assistant answering a buying question runs a live web search. If nothing of yours or about you ranks for the terms it searches, nothing of yours gets retrieved, and you cannot appear in an answer built from pages that were never fetched. Ranking is the entry ticket.

So “GEO is replacing SEO” is not a strategy, it is a slogan with a subscription attached. The accurate version is that a second scoreboard now sits on the same field, and it is scored differently.

The three things that genuinely differ

1
The pages that decide it are mostly not yours
In the 3 categories we measured, the answers were built from 131 cited sources and the domains that kept deciding each category were third-party ones. That is the biggest practical shift: a lot of the work moves off your own domain, where you have influence rather than control.
2
The unit is a buying question, not a keyword
You track tens of questions, not thousands of keywords, because an assistant is answering a question rather than matching a term. That makes the whole thing cheaper and it makes the question set itself a decision worth taking seriously: pick the ten your buyers actually ask.
3
A win often does not come with a click
Being named in a recommendation has value even when nobody visits, which breaks a measurement habit most teams have built their reporting on. It is the hardest of the three to adjust to and the one people argue about most.

What stays exactly the same

Writing something worth citing. Being technically reachable and fast. Earning mentions from places people trust. Answering the question properly rather than around it. None of that changed, and a good SEO team is already most of the way to being a good GEO team.

Where to move budget first, if you are going to

Measure before you move anything, because the answer differs by category more than any framework admits. In our measurement one category was decided by a single niche blog and another by Reddit outright, and a plan built for the first would have wasted every hour spent on the second.

The one reallocation the data supports generally is worth naming: directories. Across the 18 answers we read, review directories accounted for 1 of 131 sources, 0.8%. If a listing renewal is in your budget, test whether your own category behaves the same way before you sign it again.
