What stays exactly the same
The large majority of what makes a page rankable in Google also makes it citable by an AI answer engine, because both systems are reading the same underlying signals: technical crawlability (a page an AI crawler can't fetch can't be cited, same as Googlebot), genuine topical authority built over time, structured data that makes content machine-parseable, and third-party citations that function as trust signals to both a search ranking algorithm and an LLM's retrieval step. None of this is GEO-specific work — it's SEO fundamentals, and a site skipping them isn't ready for GEO regardless of what a GEO-specific vendor pitches.
What actually changes: three specific things
| Change | What it means in practice |
|---|---|
| AI-crawler discovery | An llms.txt file and confirming GPTBot/ClaudeBot/PerplexityBot/Google-Extended aren't blocked in robots.txt — a step SEO never required, since Googlebot doesn't need a curated file pointing it to your best pages |
| Answer-structure discipline | A direct, extractable answer near the top of a page — a specific figure or fact stated plainly, not hedged — because an AI engine typically quotes or paraphrases a short passage rather than sending a visitor to read the whole page the way search ranking assumes |
| Measurement | Tracking whether ChatGPT, Perplexity, Claude and AI Overviews actually cite or recommend you for real prompts — a genuinely different measurement discipline from rank-tracking, since there's no public "position 1" equivalent inside an AI chat response |
Why this matters: it changes the budget conversation
If GEO were a wholesale new discipline, it would justify a wholesale new budget line and a second full campaign to run alongside SEO. Because it isn't — because it's SEO's existing foundation plus a narrow, genuinely specific addition — the honest scoping conversation is "what does this site already have, and what's the small remaining gap," not "here's our GEO package starting at RM X." This is exactly how we scope our own GEO service — as a layer added to an existing SEO retainer, not a separate product. See how much GEO actually costs for exactly how that plays out in practice, including why we don't sell it as a standalone product.
A concrete way to see the overlap
Run the AI visibility checker against your own site and compare what it flags against a standard technical SEO audit — in most cases, the overlap is large: missing schema, thin content without direct answers, and a robots.txt that's fine for Googlebot but never explicitly considered AI crawlers. The genuinely new item is almost always the llms.txt file and the answer-structure rewrite, not a from-scratch new campaign.
Where GEO and SEO genuinely diverge in a regulated category
For compliance-constrained industries — clinics, finance — the answer-structure discipline has to stay inside the same regulatory bounds as any other marketing content: a direct, extractable answer must still read as educational certainty rather than outcome certainty. See our clinic-specific GEO guide for how that constraint shapes the answer-structure work differently than it would for an unregulated category.
