AEO vs GEO vs SEO: What Is the Difference and How to Run All Three Together

The short version: they overlap

AEO and GEO are industry terms, not separate switches inside Google. Google describes its own guidance for AI search features as part of SEO, and its guide to AI features builds on the same foundations as the SEO starter guide.

What changes between the three is the question you ask about a page:

• SEO: can people find this page in search, and does it help them?
• AEO: does a reader get a clear, direct answer?
• GEO: when an AI engine answers this question, does it name us and cite this page?

One good page can pass all three tests. A separate page only makes sense when it solves a different problem, not when it just swaps the acronym in the title.

SEO: help people find the page

SEO, search engine optimization, is the work of helping search engines reach and understand a page, and making that page worth opening. Someone types "seo vs aeo vs geo" into Google. Your page shows up among the results, and its title and description help them decide whether to click.

SEO still matters for AI. AI engines often search the web before they answer, so a page that cannot be found, loaded or indexed is a page they are unlikely to cite.

Keep three stages apart when you check a page in Google:

1. Crawling: Google fetches the page.
2. Indexing: Google processes it for possible inclusion in search.
3. Appearing: Google shows it for a particular search.

A page can be reachable without being in the index yet, and an indexed page can still be missing from the results you check. Google's URL Inspection tool in Search Console shows which stage a page has reached.

AEO: help people get the answer

AEO, answer engine optimization, is the work of making your information useful as a direct answer, whether that answer shows up in a search feature or an AI reply.

Picture a reader asking, "Do I need separate pages for SEO, AEO and GEO?" A paragraph about the future of search will not help them. A direct answer in the first two sentences, followed by a small example, will.

An answer can help the reader even if they never click through to your site. That is why AEO is judged by what the answer says, not only by visits. For a closer look at how the two differ in practice, read AEO vs SEO.

GEO: get named and cited in AI answers

GEO, generative engine optimization, is about how you appear in answers written by AI: whether your brand is named, whether it is described accurately, and whether your page is linked as a source.

This is where the mechanics matter. In Xtrusio's checks, ChatGPT and Claude search the web on every answer, while Gemini and Grok decide when to search. The pages those searches find, and the sites the engines already trust, shape what gets cited. AI answers rarely cite only brand websites. They draw on blogs, LinkedIn, Medium, Reddit, YouTube, industry publications and press coverage.

So GEO is not only about your own site. It is about being present in the places the engines read when they look for an answer.

Do you need special formatting for AI?

No, at least not for Google. Google's AI search guidance says there is no special schema required for its AI features, and no ideal page length or rule to split content into tiny chunks. Structured data still helps with other search features, and short sections help people follow a page. Treat both as good writing practice, not as an entry ticket to AI answers.

Other AI engines do not publish the same rules, which is one more reason to check the real answers instead of guessing.

How to run AEO, GEO and SEO together

The simplest way to run all three is to put buyer questions at the center and let each discipline answer its own test. Here is the workflow, and where Xtrusio does the work.

1. Start from the questions your buyers ask. Pick the questions people ask before they choose a product like yours. Xtrusio asks ChatGPT, Claude, Gemini, Perplexity, Grok, Google AI Overviews and Google AI Mode those questions, and keeps every full answer, every brand named and every page cited.

2. See where you stand. Xtrusio reports visibility, share of voice, sentiment, average position and citations, broken down by engine, topic and buyer persona. You see which questions name you, which name others, and which pages the engines rely on.

3. Plan from what the engines actually search. Xtrusio records the searches ChatGPT, Claude, Gemini and Grok run, and drafts a content plan for each buyer question from those searches and the sites they cite. Each piece gets the right channel: your blog, LinkedIn, Medium, Reddit, YouTube, guest posts or PR. You approve the plan.

4. Write and publish. Xtrusio writes and scores articles, checks every link before approval, and publishes to your blog where it is connected. It also drafts LinkedIn posts, YouTube scripts, Medium essays and press releases from each article. Link Strategy tracks each guest post, PR placement and published piece through to its live URL and shows whether an engine cites the live URL for the question it targets.

5. Protect your SEO. Xtrusio connects to Google Search Console and flags pages that are losing position, demand or freshness, with the reason in plain words. Your AI work never comes at the cost of the search traffic you already have.

6. Prove the result. A page counts as a win only when an engine's answer to the question it targets cites that exact URL in a later scan.

How will you know it worked?

Pick measures before you make changes, and keep them separate:

• Ranking: your page holds a position in search for a query. That does not mean AI cited it.
• Brand mention: an AI answer names your company. That does not mean it linked to you.
• Citation: the answer lists your page as a source. This is the strongest sign your content is being used.

When you count, keep it simple and checkable. Ask the same fixed questions on each engine, report the result as "named in 3 of 10 answers", and keep the full answers so anyone can see exactly what each engine said and which pages it cited.

Then run the same test after you publish: same questions, same engines, same counting rules. If an engine now cites the exact page you wrote for that question, it worked. That before-and-after on the same question is what Xtrusio shows you.

For business impact, also look at visits and real actions such as sign-ups or inquiries. A mention is a good sign, not a sale.
