Generative Engine
Optimisation Services
When someone asks ChatGPT “what is the best accountant for small businesses in Philadelphia” or asks Perplexity to recommend a physiotherapy clinic in Sydney, the answers they receive come from specific sources. Those sources were not chosen by chance. They earned their citation through how their content is structured, how their authority is established across the web, and how clearly their information can be extracted and used in an AI-generated response.
Generative Engine Optimisation, or GEO, is the process of structuring and positioning your content so that AI systems like ChatGPT, Perplexity, Google Gemini, and Google AI Overviews cite your business when they answer relevant questions. It is the next layer of search visibility after traditional SEO.
What Is Generative Engine Optimisation
Traditional SEO optimises for ranked positions in a list of blue links. A user sees your link in position three and may or may not click. GEO optimises for inclusion in an AI-generated answer. The AI engine cites your brand, your statistic, or your definition directly in its response. Users consume your content without visiting your site, and they associate the knowledge with your brand.
The term was formalised in academic research published in 2024 by researchers from Princeton, Georgia Tech, and IIT Delhi. It entered mainstream marketing in 2025 as AI search tools reached significant scale. ChatGPT now handles over 800 million weekly active users. Perplexity processes hundreds of millions of monthly queries. Google AI Overviews appear in up to 60% of search results pages. Gartner projects a 25% decline in traditional search volume by 2026 as users migrate toward AI-powered interfaces.
This shift does not make traditional SEO redundant. The businesses most frequently cited by AI systems are almost always those with strong traditional SEO foundations. GEO is an additional optimisation layer, not a replacement.
How AI Search Engines Choose What to Cite
AI systems do not rank results the way Google does. They retrieve relevant content from their training data and live web indexes, synthesise it into a narrative answer, and attribute it to sources. The signals that increase citation probability are different from traditional ranking signals.
01
Source authority
Content from websites with strong domain authority, established E-E-A-T signals (expertise, experience, authoritativeness, trustworthiness), and reputable external mentions is more likely to be cited. The same signals that help traditional SEO also help GEO, but GEO places greater weight on third-party corroboration.
02
Direct-answer structure
AI systems extract answers, they do not browse pages the way a human would. Content structured with clear direct answers to specific questions, short extractable paragraphs, and BLUF (Bottom Line Up Front) formatting is significantly more citation-friendly than long-form prose that buries the answer.
03
Statistical and factual content
Research from Princeton’s 2024 study found that adding statistics and source citations can boost AI citation rates by 30 to 40%. Verifiable, specific facts with attributed sources are more likely to be extracted and cited than general claims.
04
Schema markup and structured data
FAQ schema, Article schema, and other structured data help AI crawlers understand and categorise content more precisely, increasing the probability that the right content surfaces for the right query.
05
Bing index presence
ChatGPT’s web search functionality uses Bing’s index, not Google’s. A website that ranks on Google but is not properly indexed in Bing is invisible to ChatGPT regardless of its Google rankings. Submitting to Bing Webmaster Tools and ensuring Bing crawls the site correctly is a specific GEO technical requirement.
06
Tone and framing
Semrush research found that Q&A formatting increases AI citation rates by 25%, while promotional language reduces them by 26%. Content that sounds like marketing copy is less likely to be cited than content that sounds like expert information.
What Our GEO Services Cover
01
Content Structure Audit and Optimisation
We review your existing content for AI citation readiness. This covers the clarity of direct answers within each piece, the presence of verifiable statistics and source citations, heading structure, and paragraph length. We rewrite or restructure content to maximise extractability by AI systems without compromising its usefulness to human readers.
02
Schema Markup Implementation
We implement the structured data that helps AI crawlers categorise your content: FAQ schema for question-and-answer content, Article schema for editorial content, LocalBusiness schema for local businesses, and appropriate domain-specific schema for healthcare, legal, and other specialised industries.
03
Bing Index and AI Crawler Setup
We audit your Bing indexation, submit your sitemap to Bing Webmaster Tools, and check robots.txt and llms.txt configurations to ensure AI crawlers from OpenAI (GPTBot), Perplexity, and Anthropic can access and index your content. As Cloudflare’s 2025 report noted, GPTBot crawls approximately eight times more frequently than Googlebot, meaning technical fixes take effect faster for AI citation than for Google rankings.
04
Brand Entity and Authority Building
AI systems are more likely to cite brands with established entity recognition across the web. We build and strengthen your brand’s entity profile through consistent NAP signals, Wikipedia-style information consistency, and earning citations from established industry publications and directories that AI systems draw from as authoritative sources.
05
Citation Monitoring
We track your brand’s citation rate across ChatGPT, Perplexity, Google Gemini, and Claude by running target queries regularly and documenting where your business appears versus where competitors appear. This baseline and ongoing monitoring shows whether GEO work is producing results and which queries represent the biggest opportunities.
GEO vs Traditional SEO: How They Work Together
GEO does not replace traditional SEO. The two disciplines share a common foundation and reinforce each other.
Strong domain authority from quality backlinks improves both Google rankings and AI citation probability. Well-structured content that answers specific questions ranks well in traditional search and is more likely to be extracted by AI systems. Technical SEO that ensures clean crawlability benefits both Google and AI crawlers.
The difference is in the additional layer GEO adds: direct-answer formatting, structured data, Bing index presence, third-party corroboration, and monitoring across AI platforms rather than just Google Search Console.
Businesses that invest in both build visibility across the full spectrum of search behaviour: traditional blue-link search, local map pack search, and AI-generated answer search. Each channel reaches a different type of searcher at a different stage of their decision process.
Who GEO Is Most Relevant For
GEO produces the clearest early results for:
B2B companies and professional services
Potential clients increasingly ask AI tools to identify and shortlist service providers before they ever visit a website. A law firm, accounting practice, or consultancy that is cited by ChatGPT when a prospect asks for a recommendation enters the buyer's consideration set before any traditional search interaction.
Healthcare practices
Patients use AI tools to research conditions, treatments, and providers. Clinics and practices that appear in AI-generated answers for relevant health questions build trust at the earliest stage of the patient acquisition journey.
Specialist knowledge businesses
Any business that produces expert content in a defined area — a financial advisory firm, an SEO agency, a software company — benefits from GEO because their content is the type of specific, knowledgeable material AI systems are designed to surface.
Frequently asked questions
What Is the Difference Between GEO and SEO?
Traditional SEO optimises for ranked positions in Google’s blue-link results. GEO optimises for citation in AI-generated answers from ChatGPT, Perplexity, Gemini, and similar tools. Both rely on content quality and authority, but GEO places greater weight on direct-answer formatting, structured data, Bing indexation, and third-party citation.
How Long Does GEO Take to Produce Results?
There is typically a four to eight week lag between publishing optimised content and appearing in AI-generated answers, based on AI crawler schedules and training update cycles. Citation monitoring should begin at the four-week mark after major content or technical changes.
Does My Business Need GEO if I Already Rank Well on Google?
Google rankings and AI citations are related but not identical. A site that ranks well on Google will generally have better GEO citation probability than one that does not, but ranking on Google does not guarantee AI citation. Bing indexation, structured data, content formatting, and brand entity signals all affect AI citation independently of Google rankings.
How Do You Measure GEO Results?
By running target queries through ChatGPT, Perplexity, Gemini, and Claude regularly and documenting whether your business is cited and in what context. Referral traffic from AI platforms (visible in Google Analytics as traffic from perplexity.ai, chatgpt.com, and similar sources) also provides a measurable indicator of AI visibility.
Is GEO Only Relevant for Large Companies?
No. Small and medium businesses in specific niches can achieve strong AI citation rates with well-structured content and proper schema markup, often faster than larger companies with more generic content. The specificity of the answer matters more than the size of the business producing it.
