0:00 — The short answer — and the trap

Short answer: yes, you still need SEO. But it is no longer the whole job. And here is the uncomfortable part. You can rank number one on Google, and never once be named by ChatGPT.

Ranking and being recommended are now two separate outcomes, and most brands are resourcing only one of them. SEO and GEO are not rivals. They are two different jobs that happen to share some of the same plumbing. Let me show you where they overlap, where they split, and how to spend your effort.

0:40 — What SEO is actually for

Start with what each one is actually for. SEO, search engine optimisation, gets your page to rank in a list of links when someone searches. The win condition is a position. You are result number three, someone clicks, they land on your site.

0:59 — What GEO is actually for

GEO, generative engine optimisation, gets your brand named and recommended inside an AI's answer, when someone asks ChatGPT or Perplexity what to buy. The win condition there is not a click. It is being said.

1:16 — Why you can't drop either one

Here is why you cannot just drop one for the other. A growing share of buying journeys now run through an assistant. No list of links, just an answer with a few brand names. If you are not in that answer, the shopper never knows you exist, no matter how well you rank. That is the case for GEO.

But plenty of people still search the old way, AI answers still pull heavily from pages that rank well, and your highest intent traffic, the person who already knows your name and is ready to buy, still arrives through search. That is the case for keeping SEO.

1:52 — The foundation they share

So they are different jobs. But, and this is the useful part, they are not separate piles of work. They share a foundation.

Both reward the same core hygiene. A site that loads, that crawlers can reach, with clear page structure and genuinely useful content. Do that badly and you lose at both. So the foundation is one investment, not two.

2:19 — Where they split

Where they split is what you optimise on top of that foundation. And this is where that number one ranking trap comes from.

SEO leans on signals like backlinks, keyword targeting, and technical ranking factors. Work designed to climb a list. A lot of it is competitive positioning. Being a bit better than the page above you.

GEO leans on something different. Clarity, and corroboration. Can a model read your key facts, in plain visible text, not buried in code or an image? Are those facts complete and consistent enough that the model can describe you confidently? And does the rest of the web agree with what you say about yourself?

GEO is not about beating the page above you. It is about being clear and trustworthy enough that an AI will stake its answer on naming you.

3:15 — Rank #1 and still get skipped

That is how a page can rank number one, win the click, and still get skipped by every assistant. The facts that matter live in a spec table the model did not read. Or nothing on the site cleanly answers the question the way it was asked. Winning one outcome does not hand you the other.

3:36 — How to spend your effort

So how should you actually spend your effort? Three steps. One. Protect the shared foundation. That pays off everywhere. Two. Keep doing SEO for the journeys that still run through search, especially your high intent, brand aware traffic. Three. Add GEO as a distinct workstream, because nothing in your SEO checklist guarantees you get named in an AI answer.

4:05 — What Geoffy does

That distinct workstream is what Geoffy is. It engineers your product pages so AI can read and repeat them, then tracks whether the fixes actually land you in the answers.

4:16 — SEO finds you. GEO gets you said.

Here is the way to hold it in your head. SEO gets you found by people who are searching. GEO gets you said by machines that are answering. One wins clicks, the other wins the answer itself. And from here on, you need both jobs on the payroll.

If that was useful, the next video tackles the question every brand asks once they start checking. Why does AI keep recommending my competitor instead of me? See you there.

For more than two decades, online visibility has revolved around Search Engine Optimisation (SEO).

Brands optimised websites to rank for keywords in search engines. If your page appeared near the top, customers were more likely to click and buy.

Discovery behaviour is now shifting.

Consumers are increasingly asking AI assistants for recommendations instead of browsing search results. Tools such as ChatGPT, Gemini, and Perplexity can analyse products, compare options, and generate answers to complex buying questions.

This shift is creating a new optimisation discipline: Generative Engine Optimisation (GEO).

Traditional search results compared with an AI-generated answer

The traditional SEO model

Search engines index pages and rank them using signals such as:

  • keyword relevance
  • backlinks
  • page authority
  • content quality
  • technical crawlability

When a user searches for a query like best standing desk, they get a list of links and perform the comparison themselves.

In this model, the user does the comparison work.

The rise of AI-assisted product discovery

AI assistants change this process.

Instead of returning ten links, they analyse information and produce a direct recommendation.

A typical journey now looks like:

Question -> AI analysis -> Recommendation -> Click -> Purchase

In this model, the AI performs the comparison work before the user sees results.

Why this changes optimisation strategy

In traditional SEO, visibility depends on ranking position.

In AI discovery, visibility depends on whether the assistant can:

  • understand the product
  • evaluate its attributes
  • determine relevance to the user’s question

This is the core focus of GEO.

What is GEO?

Generative Engine Optimisation (GEO) is the process of structuring product information so AI systems can interpret and recommend it.

Where SEO focuses on ranking pages, GEO focuses on AI-readable product meaning.

Key GEO elements include:

  • structured product attributes
  • machine-readable data formats
  • content that answers at every depth of intent
  • semantic relationships between products

SEO optimises for visibility in search results.

GEO optimises for inclusion in AI recommendations.

How AI systems evaluate products

Large language models do not simply match keywords. They evaluate fit.

For a query like best running shoes for flat feet, AI systems may evaluate:

  • stability
  • arch support
  • cushioning
  • price range
  • trust context

Products with clear structured attributes are easier to recommend.

Does GEO replace SEO?

No.

Search engines remain a major traffic source. GEO complements SEO rather than replacing it.

The channel mix is expanding across search engines, AI assistants, social platforms, and marketplaces.

The future of ecommerce visibility

Discovery has evolved through web directories, search engines, and now AI-assisted discovery.

The next winners will be brands whose product information is clear, structured, and machine-readable.

That is the goal of GEO.

Frequently asked questions

What is the difference between SEO and GEO?

SEO helps webpages rank in search results. GEO helps products appear in AI-generated recommendations.

Is GEO only relevant for ecommerce?

GEO concepts apply broadly, but ecommerce is currently one of the clearest use cases.

Do I still need SEO if I use GEO?

Yes. SEO remains foundational. GEO adds an AI discovery layer.

How can brands prepare for GEO?

Start by improving product attribute structure, schema coverage, and intent-aligned discovery content.
