Is "AI SEO" a separate service you need to buy?

No — "AI SEO", GEO and AEO are not a separate discipline from search engine optimisation, and a package sold under those names usually bundles work that should already be part of any competent SEO engagement: crawlable pages, genuinely helpful content, consistent business data and structured markup. There are a small number of things that are genuinely additional (checking robots.txt against AI crawlers, testing what assistants say about you), but they're a few hours of extra work, not a second monthly retainer.

What is "AI SEO" actually?

"AI SEO" is the umbrella marketing term for getting your business mentioned in AI-generated answers: ChatGPT, Perplexity, Gemini, Copilot and Google's AI Overviews. You'll also see it called GEO (generative engine optimisation) or AEO (answer engine optimisation) — three labels for the same idea, applied inconsistently depending on who's selling it. None of them describes a different set of technical work to traditional SEO. What changes is the target format: a synthesised answer instead of a list of ranked links.

Will AI replace SEO?

No, and the two aren't in competition. AI-generated answers, including Google's own AI Overviews, are built by retrieving from the same organic index that traditional search results come from. A page that can't rank or get snippeted in ordinary search can't get cited in an AI answer either — the AI layer sits on top of ranking, it doesn't bypass it. So "should I do SEO or AI SEO" is the wrong question. Without the SEO groundwork, there's nothing for the AI layer to find.

Is GEO the same as SEO?

Functionally, yes, for almost everything that matters: crawlability, page speed, mobile usability, clear headings, helpful and original content, and consistent business details across your site, Google Business Profile and directories. All of that is standard SEO practice, done well, and none of it needs relabelling to count as "AI-ready". Google's own guidance on optimising for AI features says as much directly: it frames this as an extension of existing SEO fundamentals, not a parallel discipline. The only real addition is emphasis — writing the answer so it can be lifted cleanly, and making sure AI crawlers aren't blocked by accident.

What would you actually be paying extra for?

This is where it's worth being specific, because "AI SEO package" is vague enough to hide almost anything. Some agencies sell a bundle that's 90% work you should already be getting from your SEO provider, repackaged with a new invoice line. The table below splits out what's legitimately part of any SEO engagement from what's a genuinely separate, billable extra.

Work item	Where it belongs
Crawlable, indexable, fast pages	Standard SEO — not an AI extra
Helpful, original content with a clear answer up front	Standard SEO — not an AI extra
Consistent NAP data across site, GBP, directories	Standard SEO / local SEO — not an AI extra
Schema markup (Organization, LocalBusiness, Article)	Standard SEO — earns rich results, not required for AI features
Checking robots.txt allows GPTBot, ClaudeBot, PerplexityBot	Genuine extra — a 10-minute check, not a retainer
Testing what ChatGPT/Perplexity currently say about your business	Genuine extra — manual, periodic, useful as a baseline
"Guaranteed AI ranking" or "AI visibility score" tracking	Treat with caution — see below

Is AI content bad for SEO?

Wrong question in a different direction, but worth answering since people searching for "AI SEO" often mean this too. Google doesn't penalise content for being AI-assisted; it penalises content that's unhelpful, unoriginal or written to game rankings rather than answer a question, regardless of how it was produced. The risk with AI-written pages isn't the tooling, it's that mass-produced, generic copy reads exactly like every other AI-written page — which is the opposite of the first-hand expertise both Google and AI systems are trying to surface.

Where "AI SEO" packages overpromise

The area to be genuinely sceptical of is anything sold with a guaranteed, precisely measurable outcome: "AI ranking" scores, guaranteed ChatGPT mentions, or fixed placement in AI Overviews. No reliable equivalent of a rank tracker exists yet for AI-generated answers the way it does for Google's ten blue links, and no vendor has privileged access to how these systems actually select sources. Search Console's Generative AI report is the one solid measurement tool currently available, and it only covers Google's own AI features — nothing comparable exists for ChatGPT or Perplexity. A provider promising precise, guaranteed AI visibility reporting is selling certainty that the underlying technology can't yet support.

When is paying extra for "AI SEO" actually justified?

When it's scoped as real, bounded additional work rather than a rebrand: an AI-crawler access audit, a round of restructuring existing content into more directly quotable answers, or ongoing manual checks of what assistants say about your business over time. That's legitimate, useful and worth a modest extra line item. What isn't justified is paying a second monthly retainer for work that duplicates what a competent SEO provider should already be doing. If an agency can't clearly separate the two, ask them to. For more on what the practical work actually involves once you strip the labels away, see our guide to what generative engine optimisation actually involves, and for a fuller side-by-side comparison, GEO vs SEO: what's the difference? Related but separate: whether an llms.txt file is worth adding (it's low-effort and harmless, but Google has confirmed its own Search ignores it).
