GEO vs SEO
Two different systems.
Two different strategies.
SEO gets you found on Google. GEO gets you cited by ChatGPT, Perplexity, and Google AI. They use different signals, reward different things, and require different work. Here's the full picture.
SEO — Search Engine Optimization
The practice of optimising a website to rank higher in Google search results. When someone types a query into Google, SEO determines whether your page appears in the list — and how high.
Primary signals
- ·Keyword relevance and placement
- ·Backlinks from other websites
- ·Page speed and Core Web Vitals
- ·Technical site health
- ·Domain authority over time
Result
A ranked position in a list of links. The user still has to click, compare, and decide.
GEO — Generative Engine Optimization
The practice of structuring a business's online presence so AI systems — ChatGPT, Perplexity, Google AI Overviews — cite it when users ask relevant questions. GEO determines whether your business is named in the answer.
Primary signals
- ·Schema markup and structured data
- ·Entity consistency across all sources
- ·Question-answering content (FAQs)
- ·Third-party mentions and reviews
- ·Topical authority in a defined niche
Result
A named recommendation with reasoning. The buyer arrives pre-sold on your business.
How they compare
| Factor | SEO | GEO |
|---|---|---|
| Target system | Google, Bing search index | ChatGPT, Perplexity, Google AI Overviews |
| Output | Ranked list of URLs | Named recommendation with reasoning |
| User action required | Click, compare, decide | Often acts on the recommendation directly |
| Primary technical signal | Keywords + backlinks | Schema markup + entity consistency |
| Content format | Long-form keyword-rich pages | Question-answering, FAQ-structured content |
| Time to first result | 3–12 months typically | 30–90 days for first citations |
| Competition level | High in most niches | Low — most businesses haven't started |
| First-mover advantage | Limited — established players dominate | Significant — early movers hold positions |
| Ongoing requirement | Continuous link building, content | Maintenance after initial implementation |
| Local business benefit | Moderate — local SEO is competitive | High — AI is built to answer local queries |
Do you need both?
In the long run, yes. Traditional search and AI search are complementary channels and a business that does both well has maximum visibility. But most businesses have to sequence their investment, and the question of which to do first matters.
If you have no online presence at all: foundational SEO first. A well-structured website with basic on-page optimisation is the prerequisite for almost everything else.
If you have a functional website and some organic traffic: GEO is the higher-priority investment right now. AI search volume is growing at over 1,000% year-on-year. Competition for AI citations is far lower than for Google rankings. The first-mover advantage is still available in most niches — but it won't be for long.
If you're in a competitive Google niche: GEO may deliver faster results. Building Google domain authority in a saturated niche takes years. Achieving AI citations in the same niche often takes weeks, because AI search is still less contested.
The good news: GEO work often helps SEO too. Schema markup, structured FAQ content, and entity consistency are all signals that Google's own systems value. The two disciplines overlap more than they compete.

The businesses that establish AI citation presence now will be harder to displace as the channel matures. The parallel is early Google SEO: the businesses that invested in 2005 still benefit from that head start.
Common questions
Does good SEO automatically mean good GEO?
No. Businesses with strong Google rankings regularly have near-zero AI citation presence. The signals that drive Google rankings — keyword-matched backlinks, page speed, technical SEO — are not the primary signals AI systems use. A business needs to invest in GEO separately.
Will my current SEO agency understand GEO?
Most traditional SEO agencies are still catching up with GEO. The disciplines share some vocabulary (structured data, content quality) but the implementation details are different. Schema types that matter for AI citation, entity consistency requirements, and FAQ content structure are specialised knowledge that most SEO agencies acquired recently if at all.
Is GEO just for big businesses?
No. GEO is particularly effective for SMEs. Local and niche businesses are exactly what AI tools are trained to recommend for specific queries. A trades business, professional services firm, or specialist ecommerce store can achieve AI citations faster than a large brand competing in saturated categories.
How long does GEO take to show results?
First citations typically appear within 30–45 days of implementing structural fixes (schema markup, FAQ content, entity consistency). Consistent citation across multiple AI platforms usually follows within 60–90 days. This is faster than most SEO timelines for comparable visibility gains.
What is generative engine optimization?
Generative engine optimization (GEO) is the practice of structuring a business's online presence so that AI search tools — ChatGPT, Perplexity, Google AI Overviews — cite it when users ask relevant questions. GEO involves schema markup, structured content, entity consistency, and authority signals specifically designed for how large language models learn and recall business information.
