The Complete Guide to GEO: How to Get Your Business Recommended by AI

Search has split in two. There is Google, which returns a list of links. And there is AI search, which returns a recommendation.

ChatGPT has 900 million weekly active users. Google AI Overviews reach 1.5 billion people monthly. Perplexity is growing fast. When someone asks any of these platforms "who should I hire for X in Y?" the answer is not a list. It is one name. Maybe two.

45% of consumers now use AI to find local businesses. That number was 6% just one year ago. AI is already the third most-used discovery channel for local businesses, behind only Google and Facebook. It has passed Yelp and Tripadvisor.

But here is the gap: ChatGPT currently recommends just 1.2% of all local business locations. 83% of restaurants do not appear in AI recommendations at all. Most businesses are invisible.

This guide explains what GEO is, what the research says actually works, and what you need to do about it.

What is GEO?

GEO stands for Generative Engine Optimisation. It is the practice of structuring your business's online presence so that AI search engines can find you, understand you, and recommend you.

Traditional SEO gets you into a list of links. GEO gets you cited as the answer.

The term was coined in a peer-reviewed paper published at KDD 2024 by researchers from Princeton, Georgia Tech, and IIT Delhi. They tested nine content optimisation techniques across 10,000 queries and measured which ones actually improved AI citation rates.

Their findings are the foundation of everything that follows.

What the Research Says Works

The Princeton GEO study is the only peer-reviewed academic research on this topic. Here is what they found:

Adding statistics to your content improved AI citation visibility by 30-40%. AI models prefer content with specific, verifiable numbers over vague claims.

Citing external sources improved visibility by up to 115% for pages that were not already ranking at position 1. If you reference credible sources in your content, AI models treat your page as more authoritative.

Making content easier to read (fluency optimisation) boosted visibility by 15-30%. Clear, direct language outperforms jargon and complexity.

Keyword stuffing performed 10% worse than doing nothing. The instinct to repeat keywords does not work with AI. Models understand meaning, not repetition.

The best combination was fluency optimisation plus statistics. Together they outperformed any single technique.

One finding that matters for smaller businesses: pages already at position 1 saw little improvement. Pages ranked lower (position 5 and below) saw up to 115% improvement. If you are not the biggest player in your market, GEO gives you a disproportionate advantage.

How Each AI Platform Chooses Sources

### ChatGPT

ChatGPT drives 87.4% of all AI referral traffic to websites. It selects sources based on brand recognition in its training data, content quality and relevance, uniqueness of information, and consumer sentiment. Businesses recommended by ChatGPT averaged 4.3-star ratings according to SOCi research.

AI search traffic converts at 14.2% compared to Google's 2.8%. That is roughly 5 times higher.

### Google AI Overviews

AI Overviews now appear in approximately 48% of tracked queries, up from 13% in early 2025. 76% of cited pages come from the top 10 organic results, but this is shifting. More recent data shows only 38% of cited URLs appeared in the top 10 for the same query. Google is pulling from a wider range of sources.

55% of citations come from the top 30% of a page's content. Your opening paragraphs matter most.

Searches that trigger AI Overviews have an 83% zero-click rate. If you are not cited in the overview itself, you are not getting the click.

### Perplexity

Perplexity uses a smaller, more selective index than Google. It prioritises credibility, recency, and content structure. Pages with named authors and full bios are cited 2.3 times more frequently than anonymous pages.

Only 11% of domains are cited by both ChatGPT and Perplexity. They use fundamentally different source selection, which means you need to optimise for each.

Well-optimised content can appear in Perplexity citations within hours or days, not months. This is the fastest platform to see results on.

The Zero-Click Problem

58.5% of all searches now end without a click. For searches that trigger AI Overviews, that number jumps to 83%. Google's experimental AI Mode pushes it to 93%.

Organic traffic from Google to websites has dropped from over 2.3 billion visits per month in mid-2024 to under 1.7 billion by May 2025.

This is not a future prediction. It is already happening.

But there is a counterpoint: brands cited in AI Overviews earn 35% more organic clicks than those not cited. Being in the AI answer is becoming the new "ranking on page 1."

What You Actually Need to Do

Based on the research, these are the GEO techniques that have evidence behind them.

### 1. Structure your content for citation

Write in clear, direct paragraphs of 60-100 words. Sentences of 15-20 words. AI models extract content at the paragraph level. If your key information is buried in a 500-word block of text, it will not get cited.

Include specific numbers. "We reduced page load time from 4.2 seconds to 0.8 seconds" is citable. "We made the website faster" is not.

### 2. Implement schema markup

Structured data helps AI systems understand what your business is, what you do, and where you operate. The specific schemas that matter: Organisation or LocalBusiness, Person (for founders and team), FAQPage, Service, BreadcrumbList, and Article for blog posts.

A BrightEdge study found that sites with structured data and FAQ blocks saw a 44% increase in AI search citations. FAQ schema specifically increased AI Overviews inclusion by 31%.

### 3. Build entity authority

AI models do not just read your website. They aggregate information about your business from across the web. Your Google Business Profile, LinkedIn, industry directories, review platforms, and any third-party mentions all contribute to how AI models understand and trust your business.

Only 45% of brands visible in traditional local search are also recommended by AI platforms. Entity authority requires separate, deliberate investment.

### 4. Get reviews

ChatGPT-recommended businesses average 4.3-star ratings. Reviews are a trust signal for both Google and AI models. For local businesses, getting to 5 or more Google reviews is a threshold that measurably impacts visibility.

### 5. Ensure AI crawlers can access your site

Check your robots.txt file. Many websites accidentally block GPTBot, ClaudeBot, and PerplexityBot. If AI crawlers cannot read your site, you cannot be cited.

### 6. Add named author information

Pages with named authors and full bios are cited 2.3 times more frequently than anonymous pages. If you are a founder or specialist, make that visible on your content.

What Does Not Work

Keyword stuffing. The Princeton study proved this performs worse than doing nothing.

Generic schema markup. One study found pages with generic FAQ schema averaged fewer citations than pages with no schema at all. Bad implementation is worse than no implementation. The schema needs to be specific and accurate.

Ignoring traditional SEO. 76% of AI Overview citations still come from pages in the top 10 organic results. GEO builds on top of SEO, it does not replace it.

The Timeline

This is not instant. But it is faster than traditional SEO for new entrants.

Content optimised for Perplexity can appear in citations within days. ChatGPT and Google AI Overviews typically take 2-4 months as models retrain and re-index. Entity authority compounds over 6-12 months.

The businesses that start now will establish positions that are difficult for later entrants to displace. AI models are trained on historical data. Authority compounds.

Where to Start

Check where you stand right now. Ask ChatGPT, Perplexity, and Google AI Overviews about your business category and location. If you are not in the answer, you know there is work to do.
