SEO, AEO and GEO get used interchangeably in vendor copy, and the arguments about which term is correct are the least useful part of the topic. The distinction that changes what you do on Monday is not linguistic — it is instrumental. Each one plays out on a different surface, and each surface is visible to a different tool. Search has twenty years of first-party instrumentation behind it. Answer surfaces are half-covered by that same instrumentation. Generative engines have none at all. Planning around that gap is the actual work.
One honest definition each
Win a position in a ranked list
Search Engine Optimization. The unit of success is a ranked URL — your page, in a list of links, above your competitors'. The user still chooses, and the click is the point.
Win the answer on the results page
Answer Engine Optimization. The unit is an extracted passage — the snippet, the AI Overview, the People-Also-Ask expansion, the thing a voice assistant reads aloud. Still a search-engine surface, still partly instrumented, but the click is often suppressed by design.
Win a citation inside a generated answer
Generative Engine Optimization. The unit is a cited source in an answer written by an engine that may have no results page at all. The page that gets cited is frequently not yours, and no console anywhere reports it happened.
The machine each one optimizes
| SEO | AEO | GEO | |
|---|---|---|---|
| Pipeline | crawl → index → rank | crawl → index → extract | retrieve → rerank → synthesize |
| Unit of success | A ranked URL | An extracted passage | A cited source |
| Where it shows up | The results list | An answer block above it | A written answer, often with no list at all |
| Whose page usually wins | Yours | Yours | Somebody else's |
| The click | The whole point | Frequently suppressed | Frequently never happens |
| First-party instrument | Search Console | Search Console, partially | None exists |
Read the bottom row first, because it is the one that decides how you spend your week. Two of these three disciplines report on themselves. The third does not, and pretending otherwise is how teams end up managing the surface they can see instead of the one their buyers are using. The mechanics of that third pipeline — and why retrieved and cited are two different gates — are covered in GEO vs SEO and discoverability vs. selectability.
Google Search Console: exactly what it sees
Search Console is the only first-party record of how Google's own systems treat your site, and it is free. For SEO it is the scoreboard. For AEO it is a partial one. For GEO it is blind. Knowing which of its reports answers which question keeps you from over-reading it:
- Performance — impressions, clicks, click-through rate and average position, sliceable by query, page, country and device. This is the SEO scoreboard, and it is the only place your real query set lives rather than a third-party estimate of it.
- URL Inspection — for one URL: is it in Google's index, which canonical did Google pick, when was it last crawled, and is it eligible to be served. The single most under-used diagnostic on this list.
- Indexing / Pages report — the same question at site scale, bucketed into indexed, Crawled – currently not indexed, and Discovered – currently not indexed. Those three buckets are a discoverability diagnosis in first-party form.
- Sitemaps — the submission lane, and the right one. Bulk, repeatable, and honest about what Google did with each URL.
The index is the one gate you can check for free
Before any of the three disciplines can work, the page has to exist in an index. That is obvious for SEO and AEO, where Google's index is the substrate. It is less obvious — and more often skipped — for GEO, because several engines reach the open web through a search index rather than crawling it live. Whatever else is uncertain about AI retrieval, a page that no index holds is a page no retriever can pull. Checking that costs nothing:
Inspect the URL you actually want cited
Not the homepage. The specific page that answers the buying question, run through URL Inspection. Anything else is a guess about a page you did not check.
Read "Discovered – currently not indexed" as a reach problem
Google knows the URL exists and has not bothered to fetch it. That is a crawl-budget and off-site-authority signal, not a copywriting one. Rewriting the page will not fix it.
Read "Crawled – currently not indexed" as a selection problem
Google fetched the page, looked at it, and declined to keep it. That is the same shape of failure as being retrieved by an AI engine and never cited: you were in the room and were not chosen.
Submit through a sitemap, not one URL at a time
Manual submission is a fine spot-check and a terrible process. The sitemap is the durable lane, and its report tells you what happened to every URL rather than one.
Re-check after a crawl, not the same afternoon
Indexing decisions are not real-time, and neither are the downstream effects. Judging a fix within hours produces noise you will then have to un-believe.
Can Google Search Console measure AI visibility?
No. It measures Google Search — your queries, your impressions, your indexation. AI Overview activity is folded into those totals rather than separated out, and nothing in Search Console knows whether ChatGPT, Claude, Perplexity or Grok named you, what they said, or who they cited instead. It is the right tool for the index gate and the wrong tool for the citation question.
Where the instrumentation runs out
Search Console stops at Google's property line. Generative engines publish no console, no query report and no citation log, so three things that matter most in GEO have no first-party source at all:
The engines outside Google
No report exists for what ChatGPT, Claude, Perplexity, Grok or DeepSeek said about your category this week. The only way to know is to ask them the questions your buyers ask, many times, and count what comes back.
Who got cited instead of you
A web console tells you a URL earned impressions. It never tells you that a competitor's comparison page was quoted in the answer where you were absent — which is the single most actionable fact in AI search.
Position and sentiment inside the answer
Being named fourth in a list, or named dismissively, is not the same as being named. Neither is a metric any search console has ever had, because a ranked list of links had no room for either.
Filling those gaps means generating the observation yourself: run a fixed prompt set against each engine, repeatedly, and read the citations out of the answers. Because that is sampling rather than a ledger, every number it produces belongs in a range with a timestamp — the reasoning is in confidence ranges, and the metric definitions in visibility metrics.
The instrument stack, question by question
| The question | What actually answers it |
|---|---|
| Is this page in Google's index at all? | Search Console — URL Inspection |
| Which of my pages are indexed, and which were declined? | Search Console — Indexing / Pages report |
| What do I rank for, and where? | Search Console — Performance |
| Did an AI Overview appear for this query, and what did it cost me? | Partly Search Console, folded into Search totals; otherwise SERP-sourced measurement, reported as an estimate |
| Did ChatGPT, Claude, Perplexity or Grok name me? | Multi-run prompt sampling against each engine — no console exists |
| Which sources did they cite instead of me? | Citation extraction from those same runs |
| Are AI crawlers even fetching my pages? | Your own server or CDN access logs (agent traffic) |
| Did any of it turn into a visit? | Referral classification in your analytics (LLM Analytics setup) |
Two things stand out in that table. The free first-party tool answers the first three rows completely and the fourth partially — which is more than most teams use it for. And every row below that has to be manufactured, because the surface it describes reports to nobody.
One order of operations across all three
These are not three programmes competing for budget. They stack, and the cheapest checks come first:
- Settle indexation. Inspect the pages that answer real buying questions. Fix reach problems and selection problems separately. This step is free, definitive, and prerequisite to everything after it.
- Make the answer extractable. A clear, self-contained answer near the top of the page, specific claims, real numbers, clean structure. This is the AEO layer, and it is the same work that makes a passage quotable by a generative engine.
- Earn the third-party ground. Most citations in AI answers point at pages you do not own — review sites, roundups, community threads. Getting into those is off-site work with a long lead time, which is exactly why it starts before you can measure its payoff.
- Instrument the part nobody reports. Fixed prompt set, several runs per cycle, citations extracted, results carried as ranges. Without this, steps two and three are unfalsifiable.
Is AEO just GEO with a different name?
In everyday usage, effectively yes — most people use them interchangeably for the same shift away from ranked links. The distinction worth keeping is the surface: AEO work usually lands on a search engine's own answer block, which Google partly reports on, while GEO work lands inside a generated answer from an engine that reports nothing. Same craft, very different visibility into whether it worked.
Does being indexed by Google get me cited by ChatGPT?
It helps and it does not guarantee. Indexation is a retrieval gate: a page no index holds is a page no retriever can find. Selection is a separate gate, decided on the page's own merits against everything else retrieved for that question — and engines vary in whether they lean on a search index, their own crawler, or no live retrieval at all.
The short version: SEO, AEO and GEO differ less in craft than in what you can prove. Search Console and the index will tell you, for free and for certain, whether your page is even eligible to be found. Nothing you already own will tell you whether an engine chose you, what it said, or who it named instead — that has to be measured on purpose.
