Generative engine optimization (GEO) services are professional engagements that help brands appear in AI-generated answers on ChatGPT, Perplexity, Google AI Overviews, and Gemini. Unlike traditional SEO, which chases a ranked position in a results list, GEO targets the moment an AI engine synthesizes a response and decides whose content to surface. The goal is citation: your brand, product, or page showing up inside the answer itself.
The field took shape after a 2023 academic paper (accepted to KDD 2024) coined “Generative Engine Optimization” and demonstrated that systematic content changes could boost visibility in AI-generated responses by up to 40%. What practitioners now call GEO services is the applied, commercial version of that research: auditing, rewriting, restructuring, and monitoring content specifically to win those citations.
Most GEO work runs alongside traditional SEO rather than replacing it. Strong Google rankings still matter because AI engines pull from the same indexed web. GEO is the layer on top that ensures your pages, once indexed, are written and structured in a way AI retrieval systems actually prefer.
What GEO Services Include
GEO services cover a defined set of technical and editorial deliverables. A provider that claims to “do GEO” without touching most of these is doing something narrower than the full service.
Content restructuring for direct answers. AI engines prefer pages that lead with clear, concise answers. GEO work involves rewriting intros to answer the implicit question immediately, shortening paragraphs to two to four sentences, and adding explicit definitions at the top of key sections. This is the single highest-leverage change for most sites.
Schema markup implementation. FAQPage, HowTo, Article, Organization, and Product schemas all signal structure that AI retrieval systems can parse reliably. A GEO audit will identify which schemas are missing, misconfigured, or lacking the properties that engines use when selecting citation candidates. See the organization schema markup guide for what the fields actually need to say.
AI crawler access audit. If GPTBot, ClaudeBot, PerplexityBot, or Google-Extended are blocked in robots.txt, no GEO tactic will work. Providers audit the robots.txt file, check for JavaScript rendering issues that prevent crawlers from seeing content, and add an llms.txt file that gives AI agents a structured map of the site. The AI crawler access guide covers exactly which directives to allow.
Third-party mention building. AI engines weight external citations heavily, especially from sources with established trust: industry publications, review platforms, Wikipedia, and Reddit threads where real users discuss the category. GEO services include outreach to earn those placements, not just on-site optimization.
Content freshness management. Stale pages with outdated data get deprioritized. GEO providers schedule regular updates, keep dateModified tags accurate, and flag content that is at risk of falling behind competitors.
Visibility monitoring. GEO without measurement is guesswork. Providers set up systematic queries across target engines, track citation frequency over time, and identify which queries the brand is losing to competitors. Tools like Fokal automate this across ChatGPT, Perplexity, and Google AI Overviews so you see trends rather than one-off spot checks.
GEO Services vs. AEO Services
The terms get used interchangeably, which creates real confusion when evaluating providers.
Answer engine optimization (AEO) is the older term, originating around 2018 when voice search and featured snippets were the main targets. AEO work focused on structured data, FAQ formatting, and winning Google’s answer box.
GEO is the 2023-onward framing, specifically for large language model-based engines. The techniques overlap substantially (schema, direct answers, structured formatting), but GEO extends into areas AEO never covered: llms.txt files, AI crawler permissions, LLM-specific trust signals, and citation tracking across generative platforms.
A provider offering “AEO services” may or may not have updated their practice to cover AI engines. Ask specifically: do they track citations in ChatGPT and Perplexity, or only featured snippets? Do they audit GPTBot access? If the answer is no to either, it is an older AEO practice rebranded.

The Google Plus AI Citation Angle
GEO services that only target AI engines miss half the picture. Google still drives the majority of organic search traffic, and Google’s AI Overviews pull from the same indexed content that traditional Google Search uses. This means:
- Pages that rank well on Google are more likely to be pulled into AI Overviews.
- Content optimized for AI citation (direct answers, schema, structured headings) also performs better in Google’s featured snippets and People Also Ask boxes.
- Bing powers ChatGPT’s web retrieval, so good Bing performance directly affects ChatGPT citation rates.
The practical implication for anyone evaluating GEO services: the work should improve both surfaces simultaneously. If a provider says “we optimize for AI, not Google,” that is either incomplete or misleading. The two signals are interlinked.
A good GEO engagement tracks both Google Search Console performance and AI citation frequency. Rising rankings without rising citation rates, or vice versa, usually indicates a gap in the strategy. See AI search visibility for the full measurement framework.
What to Expect From a GEO Engagement
Most GEO services run as a retainer rather than a one-time project, because content and AI engine behavior both change continuously.
A typical engagement starts with an audit: which pages are blocking AI crawlers, which queries the brand is missing, which competitors are being cited instead. The audit produces a prioritized list of fixes, usually ordered by query volume and citation gap.
The first few months focus on high-leverage on-page work: restructuring key pages, adding schema, fixing crawler access, and seeding third-party mentions. Monitoring runs in parallel to establish a baseline citation rate.
From month three or four onward, the work shifts to content gap filling (new pages targeting queries the brand ranks for but is not cited in), freshness maintenance, and compound authority-building through consistent external mentions.
Results vary by starting point, but the academic research on GEO found visibility improvements of up to 40% from systematic content changes alone, before factoring in crawler access fixes or external mention campaigns.
How to Evaluate a GEO Services Provider
A few concrete questions separate providers who have genuine GEO capability from those applying a traditional SEO framework with new vocabulary.
Do they run citation checks before starting? Any serious GEO provider knows your current citation rate across key engines before proposing a scope of work. If the first conversation is about deliverables rather than your current position, that is a sign they are selling a package rather than diagnosing a problem.
Which engines do they track? At minimum, ChatGPT, Perplexity, and Google AI Overviews. A provider tracking only Google is doing SEO, not GEO.
What does their schema work cover? FAQPage and Article schemas are table stakes. Ask about Organization schema, Product schema, and entity disambiguation. The more specific the answer, the more technically mature the practice.
How do they handle content that contradicts AI engine output? This is a real scenario: an AI engine is citing an outdated or wrong description of your product. A capable GEO provider has a workflow for this, including content updates, entity record corrections, and third-party source fixes.
Do they understand the connection between Bing and ChatGPT? If yes, they will include Bing SEO in their scope. If not, they have a gap in their model.

Running GEO Yourself vs. Hiring a Provider
Brands with an in-house content or SEO team can run most GEO tactics internally once the initial audit and setup is done. The work is not technically complex in the way that, say, JavaScript SEO is. The barrier is usually attention and measurement: the tactics are known, but tracking citation rates systematically across multiple engines requires tooling that most teams do not have.
Fokal tracks AI citations automatically across ChatGPT, Perplexity, and Google AI Overviews, giving in-house teams the monitoring infrastructure that was previously only available to agencies with custom tooling. The generative engine optimization guide covers the full self-service approach, and the AI SEO hub routes to every tactical area in the cluster.
For brands that want the work done for them, a GEO agency handles the audits, content rewrites, schema implementation, and ongoing monitoring. See GEO agency for what to look for when choosing one.
