GEO vs SEO: You Need Both — Here’s the Order

SEO gets you found in search. GEO gets you found in AI. People searching geo vs seo usually arrive worried that Google work is obsolete — or that they now need three separate budgets. The truth is simpler: SEO, AEO, and GEO are three different jobs on the same website, and the order of those jobs is fixed. Get the order wrong and you pay twice for the same gap.

This post answers the anxiety first, then shows what each term actually does, where they overlap, and what to fix before you hire another agency or buy another dashboard.

AI assistants have become an additional discovery channel — not a replacement for search. More buyers now mix Google with ChatGPT, Perplexity, or Copilot during the same purchasing journey. That is why the labels multiply, and why the order of work matters.

The short answer: SEO vs AEO vs GEO

Three discovery channels. One website.

Semrush puts it plainly: “No, GEO isn’t replacing SEO — it complements it.” Their guide adds that most brands need both for a complete search visibility strategy. Google’s own AI optimization guide goes further for its products: from Google Search’s perspective, optimizing for generative AI search is still SEO. Industry shorthand (AEO, GEO) describes angles on visibility; it does not cancel the foundation.

Why SEO is not dead

SEO still does the job it always did: help people who search Google (and similar engines) find you and click through.

That work still matters because:

• Most buyers still use traditional search in the same decision journey — even when they also use AI.
• Google’s AI Overviews and AI Mode pull from the same index and quality systems that power classic rankings. If Google cannot crawl or trust your pages, you lose both the blue link and the AI summary on Google.
• SEO also feeds Bing, and Bing’s search service grounds Microsoft Copilot’s web answers. ChatGPT and Perplexity are different: each runs its own crawler and index — OAI-SearchBot for ChatGPT’s search results, PerplexityBot for Perplexity, whose index tracks over 200 billion URLs. Being in Google or Bing does not put you in theirs, which is why crawler access has to be checked per engine.
• Authority, clear pages, and healthy indexation feed every later layer. Weak SEO makes AEO and GEO harder, not optional.

What SEO still does well:

• Gets you into Google’s index and competitive rankings
• Drives measurable organic traffic and pipeline you already know how to report
• Builds the content and trust signals AI systems often reuse when they retrieve the open web

What SEO does not automatically do:

• Confirm whether ChatGPT’s or Perplexity’s readers can open your site
• Guarantee a mention when a buyer asks an assistant for vendors in your category
• Fix a security rule that blocks AI crawlers while leaving Googlebot alone

So when someone asks “why is SEO no longer relevant?” — it usually isn’t that SEO stopped working. It’s that SEO alone no longer covers the whole buying path. Rankings can look fine while another channel skips you. We see that split often in sites that rank on Google but stay invisible in ChatGPT.

What AEO adds

AEO — answer engine optimization — is the work of winning direct answers, not only a ranked link.

In practice that means structuring pages so a machine can lift a clear, authoritative reply: a definition in the first paragraph, a short how-to list, a FAQ that matches how people ask. On Google, success shows up as featured snippets, People Also Ask boxes, and AI-composed summaries.

AEO sits closest to SEO because Google still decides eligibility from indexed, snippet-eligible pages. Google is blunt about the shortcuts: “While terms like Answer Engine Optimization (AEO) or Generative Engine Optimization (GEO) are common online, many suggested ‘hacks’ aren’t effective or supported by how Google Search actually works.” Its generative features are “rooted in our core Search ranking and quality systems.” That guidance covers Google Search only — it says nothing about how ChatGPT, Perplexity, or Claude pick sources. For a plain-English walkthrough, see our Google AI optimization guide.

What AEO adds that classic “rank and click” SEO often skips:

• Question-shaped headings and lead answers
• Passages written to be quoted, not only scanned
• Content shaped for summary surfaces on the Google results page

What AEO does not finish for you: winning a snippet on Google does not mean ChatGPT will recommend you. Different engines use different crawlers, indexes, and retrieval systems. A law firm can own “how much does a trademark cost in Texas” in a featured snippet and still never appear when a founder asks ChatGPT for Dallas trademark attorneys. That gap belongs to GEO, not more snippet tweaks.

What GEO adds

GEO — generative engine optimization — is the work of making your business findable and citable inside AI-generated answers: ChatGPT, Perplexity, Gemini, Claude, and peers.

The paper that coined the term, GEO: Generative Engine Optimization (Princeton-led, KDD 2024), tested this directly across 10,000 queries: the authors took pages that were already among a query’s top search results and rewrote them, adding relevant statistics, quotations, and citations to credible sources. In their own test engine that lifted a page’s share of the generated answer by up to about 40% versus the unedited version. Keyword stuffing, by contrast, performed worse than doing nothing.

Two caveats worth stating plainly, because they are usually dropped when that number gets quoted. The gain measures how much of an answer a page occupies once it has already been retrieved — it is not evidence that editing gets an unseen page into an answer. And the headline figure comes from the researchers’ own test setup; on a live commercial engine their objective metric improved by roughly 9%, not 40%. Structure and evidence help. They do not buy a slot.

For a business site, GEO usually adds two technical jobs SEO tools rarely finish:

1. AI bot access — can the automated visitors from AI companies reach your pages, or did a security layer or robots.txt rule lock them out while Googlebot still works?
2. Machine-readable facts — do your pages (and often a short llms.txt “about us” file) state who you are, what you sell, and where you operate, with clear schema labels machines can parse without guessing? Note that Google says its Search does not use llms.txt — the file is for the assistants that do.

Our own monitoring shows how much access signals move crawler behaviour. AI bots were visiting about 604 times a week. After we submitted pages through IndexNow, traffic from OAI-SearchBot — the crawler behind ChatGPT’s search results — jumped roughly 14-fold and the weekly total peaked at 3,427 visits. It then settled at around 1,100 a week: still nearly double the old baseline, but a spike, not a new normal. That is evidence that discovery signals change how often AI readers come back. It is not evidence that AI will recommend you on a schedule.

Example — green SEO, blocked GEO:

Where they overlap — and where they don’t

Shared foundation (fix once, helps all three):

• Pages that load and are publicly reachable
• Clear, accurate copy about your offer
• Consistent business identity (name, location, services)
• Structured labels where they help machines understand entities — useful for rich results and for AI orientation
• Trust signals: reviews, mentions, third-party proof

If the door is locked or the facts are fuzzy, SEO, AEO, and GEO all suffer — even though each channel uses slightly different readers.

Where they diverge — this is where budgets get wasted:

Overlap is the foundation. Divergence is the channel. Treating geo vs seo as “pick one budget” ignores both.

What to do first: the order of work

Do not choose between SEO, AEO, and GEO. Sequence them. Skipping ahead is the expensive mistake.

What happens when the order is reversed:

• AEO content first, bots blocked: beautiful FAQ pages that Google may use — and ChatGPT never fetches.
• Citation dashboard first, access untested: a monthly fee to learn you are invisible for a reason a free access check would have shown.
• GEO files only, SEO neglected: AI might eventually read a thin site that still loses the Google traffic paying the bills.

For most owners with healthy rankings, the highest-leverage next step is step 2: verify AI access before another content project. GEO Fix is built for that layer — it ships the fix files and CMS steps (robots.txt, llms.txt, schema), not only a score. Monitoring tools like Profound or Otterly answer a later question: “Are we being named?” Different job.

Honest limit again: unblocking crawlers and clarifying facts improves eligibility. It does not guarantee a recommendation in ChatGPT, Perplexity, or Gemini.

Who benefits most?

If your customers research vendors before buying, you probably need both SEO and GEO.

• SaaS and B2B software — shortlists often start in ChatGPT or Perplexity
• Agencies and professional services — prospects compare vendors before the first call
• Law firms and healthcare — high-trust categories where accurate citations matter
• Local businesses — maps and Google still drive demand; AI answers increasingly shape the shortlist
• Ecommerce — shoppers ask assistants what to buy; product pages need to be reachable and clear

If any of those sound like you, check access before you fund another content sprint.

What to do next

Key takeaways:

• GEO vs SEO is not an either/or: SEO earns search clicks, AEO wins extractable answers, GEO opens AI assistant visibility — three jobs, one site.
• The shared foundation is reachable pages and clear facts; the divergence is crawlers, surfaces, and success metrics.
• Follow the order — SEO base, then AI access, then machine-readable facts, then answer-shaped content, then monitoring — or you will fund the wrong fix.
