What Is GEO (Generative Engine Optimisation) and Why Your Ecommerce Store Needs It Now

What GEO actually is

Generative Engine Optimisation is the practice of structuring your content so that AI-powered search engines — ChatGPT, Perplexity, Google's AI Overview, Microsoft Copilot — are likely to pull from it when answering a user's question.

Traditional SEO gets you ranked. GEO gets you cited.

That distinction matters more than it sounds. When someone asks ChatGPT "what's the best mattress topper for hot sleepers," it doesn't show them ten blue links. It writes an answer. And somewhere inside that answer, it's going to cite two or three sources it found credible. If your product page or blog isn't one of them, you've lost that customer before the session even started.

The term was coined in a 2024 Princeton research paper, which found that certain content strategies — adding statistics, citing authoritative sources, writing in a quotable way — increased how often content got pulled into AI-generated responses by up to 40%. That's not a small edge.

How GEO differs from traditional SEO

They share a foundation. Good SEO — proper technical structure, quality content, trustworthy links — still matters for GEO. A site that ranks well is generally more likely to get cited. But the tactics diverge from there.

The biggest mindset shift: SEO optimises for algorithms that rank documents. GEO optimises for models that synthesise answers. You're writing for a reader that has no intention of actually visiting your page — it just wants to extract the useful bits.

Why this hits ecommerce harder than other industries

If you run a local services business, a lot of your leads come through calls, referrals, or map listings. GEO is relevant but not urgent. For ecommerce, it's a different story.

Product discovery is moving to conversational AI fast. People are asking "what's the best protein powder for muscle gain under $60" and getting a list. They're asking "compare these two running shoes" and getting a direct answer. The traditional search funnel — query → results page → product page → purchase — is compressing. Sometimes the AI answer is the whole funnel.

This is particularly sharp for ecommerce stores in New Zealand. You're already competing against international giants with massive ad budgets. If an AI recommends an overseas alternative simply because their product descriptions are cleaner and their site structure makes them easier to parse — that's a real problem.

"Google rankings used to be the moat. Now the moat is whether an AI model finds your content trustworthy enough to quote — and that requires a different kind of work."

On the Google Shopping side, this compounds. AI Overviews are now surfacing Shopping results inline. Your product feed optimisation, which has always mattered for visibility, now feeds directly into AI-generated responses. A weak product title doesn't just hurt your Shopping rank — it makes you invisible to the AI pulling those results.

What signals GEO actually responds to

Based on the research and what's visible in real AI responses, these are the factors that tend to move the needle:

Clear, quotable answers

AI models are looking for content they can lift and use directly. Write in short, factual sentences. Lead with the answer, not the context. "Mānuka honey has an antibacterial rating measured in UMF (Unique Manuka Factor). A UMF of 10+ is considered medically active." That's a format that gets cited. Three paragraphs of warm-up before you get to the point doesn't.

Specific data and statistics

The Princeton study found that adding statistics and sourced data was the single biggest driver of AI citation frequency. Not vague claims — actual numbers. "Our conversion rate testing across 14 product pages found that adding size guides increased add-to-cart rate by 23%." That kind of specificity gets pulled. "We've seen good results with size guides" does not.

This is where analytics becomes a content asset, not just an internal report. Your own data — properly packaged — is genuinely hard for AI to source elsewhere.

Structured data and schema markup

Schema.org markup tells AI crawlers exactly what a piece of content is: a product, a FAQ, a review, an article, a how-to guide. Without it, they're guessing. FAQ schema is especially useful for GEO because it maps directly to the question-and-answer format that AI responses are built on.

If your SEO implementation doesn't include comprehensive schema markup across your product catalogue, category pages, and blog — that's the first thing to fix.

E-E-A-T: Experience, Expertise, Authoritativeness, Trust

Google formalised this framework, but it applies across all AI systems. They're trying to avoid hallucinating or amplifying bad information, so they default to sources they can verify as credible. This means: named authors with bios, published credentials, real brand information, a verifiable track record.

For ecommerce, this often means investing in content from someone with genuine product knowledge — not just keyword-stuffed category copy.

Conversational question targeting

People don't ask AI engines in the same way they typed into Google. They ask full questions: "What's the difference between an air fryer and a convection oven?" "Is merino wool worth the price?" Your content needs to answer those questions explicitly, with the question included as a heading or within the body text.

Related: GEO + Your Funnel

GEO isn't just a traffic strategy — it's a funnel entry point. Someone who discovers your brand via an AI citation is often further down the buying journey than a cold search visitor. They've already had their question answered; they want to buy.

This is why we pair GEO work with conversion rate optimisation — the traffic it generates is warmer, but your site still needs to close it.

Practical GEO for ecommerce: where to start

You don't need to rebuild your entire content strategy. A few targeted changes can move the needle quickly.

1. Audit your product descriptions. Are they detailed enough to be quoted? Do they answer real buying questions — materials, sizing, use case, comparison to alternatives? Or are they manufacturer copy-paste? An SEO audit will show you where the gaps are.

2. Build FAQ sections on product and category pages. Model the questions on what people actually ask — check Answer the Public, Reddit threads, your own customer support inbox. Then answer them cleanly and specifically. Apply FAQ schema to every one.

3. Create authoritative comparison content. "X vs Y" and "best [category] for [use case]" posts are some of the most-cited content in AI responses. If you're a NZ outdoor retailer, "Merino vs Polypropylene base layers for NZ winters" is a blog post that will get pulled by AI for years.

4. Publish data from your own store. Returns rates, best-sellers by season, customer survey results — this is original data that nobody else has. It's highly citable and almost immune to being out-competed by larger brands.

5. Fix your technical foundation. Page speed, crawlability, canonical tags, internal linking — the basics still gate everything else. If AI can't properly crawl and parse your site, none of the content work will land.

6. Connect your feed and your content. Your Shopping feed and your blog need to reinforce each other. A product with a detailed, well-optimised listing and a linked how-to article is much more likely to appear in AI responses than an orphaned product page.

GEO and paid media: they're not separate

One thing worth addressing: GEO isn't a replacement for paid acquisition. It's a different layer of the funnel.

What GEO can do is raise baseline brand awareness so your paid campaigns perform better. Someone who's seen your brand mentioned in an AI response is more likely to click your ad than someone seeing you cold. The assisted-conversion signal is real even when it's invisible in your attribution model.

We're also starting to see AI-generated ad creative become part of this picture. AI ad creatives trained on high-performing product imagery and copy can respond much faster to the kind of mid-funnel intent signals GEO generates. The two strategies work better together than either does alone.

The NZ context

There's a wrinkle specific to NZ ecommerce that's worth naming. Our market is small. That means there's less NZ-specific content for AI models to draw from — which cuts both ways.

The bad news: if your category is dominated by Australian or US content, an AI will default to those sources even when a NZ customer is asking. "Best mattress under $1500 NZ" might return recommendations priced in AUD with no availability here.

The good news: it doesn't take much to become the most authoritative NZ voice in a category. The competition for NZ-specific content is thin. A well-structured blog with NZ pricing, NZ shipping context, NZ climate and lifestyle specifics — that's achievable for most stores, and it punches above its weight in AI responses.

If you're building AI workflow automations into your content operation — using AI to help draft and scale blog output — this is where the investment pays off quickly. Consistent, specific, NZ-focused content at scale is hard to compete with.

How to measure it

This is genuinely hard right now, and anyone who tells you otherwise is selling something. There's no native "AI citation" metric in Google Analytics or Search Console yet.

What you can track as proxies:

• Direct traffic and branded search volume — if AI is citing you, brand awareness typically rises

• Zero-click impressions in Search Console — indicates AI Overview appearances

• Manual spot-checking: ask ChatGPT and Perplexity your target questions and see if you're being cited

• Share of voice tools (Semrush, Ahrefs) that are starting to track AI mentions

• Referral traffic from Perplexity.ai specifically — this shows in GA4

It's an imperfect picture, but it's enough to track directional progress. As part of any analytics setup we build for clients, we're now including GEO visibility benchmarks alongside standard SEO metrics.

The bottom line

GEO isn't replacing SEO — it's extending it. The stores that adapt early will own the AI citation layer of their categories before it gets competitive. The ones that don't will find themselves invisible to a growing share of the buying journey.

The good news is the work is mostly the same work: write better content, structure it properly, build real authority in your niche. It's just optimised for a reader that synthesises instead of scrolling.

If you want to see where your store currently stands — technically, content-wise, and in terms of AI visibility — our full SEO audit now includes a GEO readiness assessment. It's the fastest way to find out what to fix first.
