SEO has been the foundation of ecommerce marketing for 20 years. Now there's GEO (Generative Engine Optimization) and no one seems to agree on what it is, how it differs from SEO, or whether it replaces it.
This post is the practical version. What GEO actually means. What's different from SEO. What you can stop worrying about. And what you should actually do if you're running a Shopify store and have limited time.
What GEO actually is
GEO is the practice of optimizing your brand's presence in AI-generated responses: the answers that ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini give when someone asks a question about your product category.
The term was coined in a 2023 research paper and has since become the industry shorthand for this entire discipline. You'll also hear it called "AI visibility", "AI SEO", or "LLM optimization". They all mean the same thing: making sure AI mentions, recommends, and trusts your brand.
Where SEO targets the algorithm behind Google's ten blue links, GEO targets the AI systems that now often appear before those ten blue links, or replace them entirely.
How GEO differs from SEO: the practical version
| SEO | GEO | |
|---|---|---|
| What you're optimising for | Google's ranking algorithm | AI training data and live AI search |
| Primary signal | Backlinks + on-page content | Third-party editorial coverage + reviews |
| Speed of impact | Weeks to months | AI Search: days/weeks. AI Knowledge: months |
| Measurement | Google Search Console, rankings | No equivalent yet; requires active querying |
| Can you pay your way in? | Yes (Google Ads) | No. AI recommendations are organic-only |
| Does your website matter? | Critical | Less so. AI cares more about what others say about you |
The most important difference: SEO is about your website. GEO is about your reputation across the web.
Google ranks your pages. AI recommends your brand. These are different problems requiring different solutions.
What transfers from SEO
Not everything changes. Several SEO best practices also improve your GEO standing:
Structured data (schema markup). Product schema, Organization schema, FAQ schema: all of these help AI systems understand what your brand sells and where it operates. If you've invested in schema for SEO, that work carries over.
Fast, crawlable pages. AI Search tools (Perplexity, Google AI Overviews) crawl the live web, just like Googlebot. Pages that are slow, broken, or blocked from crawlers can't be cited. Standard SEO hygiene applies.
Clear, specific product descriptions. Content that directly and accurately describes what you sell, without fluff, is easier for AI to extract and cite. This aligns with the plain-language writing that SEO best practice already recommends.
Review volume and freshness. Reviews matter for local SEO. They matter even more for GEO, because AI reads review sentiment across platforms to form its opinion of your brand.
What doesn't transfer from SEO
Backlinks work differently, not irrelevantly. AI doesn't run a PageRank calculation. There's no direct equivalent of Google counting links to determine authority. But domain authority still correlates with AI visibility, because higher-authority pages are better represented in training data (they get crawled more thoroughly) and rank higher in the live web indices that Perplexity and Google AI Overviews draw from. Strong link building helps, but it doesn't translate to AI visibility at the same rate it does for Google. A brand with a strong backlink profile but weak third-party editorial coverage and reviews will underperform its DA in AI recommendations.
Keyword optimization. Stuffing keywords into your content to match search queries doesn't help with AI. AI doesn't pattern-match on keywords the way Google's algorithm does. It evaluates the overall meaning and credibility of content.
Ranking position. Being #1 on Google has no direct relationship with being mentioned by AI. We've seen brands ranked #5 or #10 for a keyword being recommended by AI because they have stronger independent review coverage than the brands ranked above them.
Your own content. For AI Knowledge models, content you publish on your own site is weighted less heavily than independent third-party content. Your blog posts and product descriptions matter for AI Search, but your editorial coverage elsewhere matters more for whether ChatGPT recommends you.
The practical priority order for a Shopify merchant
If you have limited time and need to know where to start:
1. Measure first. You can't improve what you can't see. Before doing anything else, find out which AI systems mention you, what they say, and how you compare to your main competitors. The gap between your AI Search score (live web tools) and your AI Knowledge score (training-data models) tells you which problem to solve first.
2. Audit your review presence. This is the single most accessible lever. Search for "[your brand] reviews" and check whether you have consistent, positive presence on the platforms AI cites: Trustpilot, Google Reviews, Reddit, and niche review sites in your category. Getting into two or three new review platforms is a week's work and can show up in AI Search results within days.
3. Find the buying guides that cover your category. Search "best [product type] 2026" and identify the roundups that appear. If you're not included, make a list and start outreach. A single placement in a credible buying guide is worth more for GEO than dozens of pages of content on your own site.
4. Create comparison content. Write honest "How we compare to [competitor]" pages on your domain. AI gets a lot of comparison queries and needs something to reference. If you don't provide it, AI synthesizes comparisons from whatever it finds, which may not represent you well.
5. Check your entity footprint. Confirm your brand has a Wikidata entry and appears in Google's Knowledge Graph. If not, creating a Wikidata entry takes 20 minutes and costs nothing.
Does GEO replace SEO?
No, not yet, and probably not entirely.
Google still processes billions of queries daily, and traditional organic results still drive significant traffic. AI Overviews appear on roughly 13% of US queries and are expanding, but they haven't displaced traditional search results.
The more accurate framing: GEO is a new channel alongside SEO, not a replacement for it. The brands that will win long-term are the ones that build presence in both traditional search results and AI-generated answers.
The analogy is the early days of social media. Brands that treated social as "extra" and stuck to SEO-only strategies missed a window of lower competition and higher returns. The same dynamic is playing out now with AI visibility.
SEO still matters. GEO is becoming a parallel requirement. And the brands that figure out how to do both efficiently, without doubling their workload, will have a structural advantage.
