The difference between a GEO specialist and an SEO agency is the goal. A GEO specialist works on mentions and citations in AI answers from ChatGPT, Perplexity, Copilot and Google AI Overviews, while an SEO agency works on higher positions in Google and Bing. In 2026 most businesses need both, in a fixed order. Step 1 is a crawlable, indexed website, because according to Google, AI Overviews need no extra requirements beyond the SEO basics. Step 2 is answer content: pages that answer one customer question in the first sentence, with sources and figures. Finally, step 3 is a monthly measurement with 15 to 30 customer questions per AI platform. For example, a local installer can check which businesses ChatGPT names for a question such as "who installs heat pumps in Dordrecht?". VirtuoLab in Papendrecht combines both disciplines with Next.js.
What is the difference between a GEO specialist and an SEO agency?
A GEO specialist is a consultant or agency focused on generative engine optimization. The aim is a mention or citation inside AI answers from ChatGPT, Perplexity, Microsoft Copilot and Google AI Overviews. An SEO agency is a provider focused on search engine optimization, meaning higher positions in the classic results of Google and Bing, usually tracked with Google Search Console. SEO wins a click from a list of links, while GEO wins a recommendation inside one generated answer. The term GEO is young. Researchers from Princeton University, IIT Delhi and elsewhere introduced the name in a paper on arXiv in November 2023, later accepted at KDD 2024. In practice, the two labels overlap more than the marketing suggests. Additionally, Google lists optimizing for generative AI as one of the services an SEO can offer. So the real question is not the label on a website, but which skills, measurements and responsibilities a business needs in 2026.
Where do GEO and SEO overlap?
The overlap between GEO and SEO is the technical foundation: a page must be crawlable, indexed and readable as text before any AI assistant can cite the page. According to Google Search Central, there are no additional requirements to appear in AI Overviews or AI Mode. A page only needs to be indexed and eligible to be shown in Google Search with a snippet. All existing SEO fundamentals continue to be worthwhile, according to Google. The list includes crawling allowed in robots.txt and at the CDN, internal links, important content in textual form, and structured data matching the visible text. Additionally, Google names an up-to-date Business Profile. Microsoft gives similar advice for Copilot and Bing in 2026: clear headings, tables, FAQ sections, regular updates, and fast discovery of changes via IndexNow. For example, a page blocked in robots.txt fails for SEO and for GEO at once. Whoever a business hires, step 1 is identical.
What does GEO add on top of classic SEO?
GEO adds three layers on top of classic SEO: access for AI crawlers, answer-shaped content and measurement inside AI answers. First, every AI platform uses a separate crawler. According to OpenAI, sites opted out of OAI-SearchBot will not be shown in ChatGPT search answers, although navigational links can still appear. Perplexity recommends allowing PerplexityBot, and Anthropic warns that blocking Claude-SearchBot may reduce visibility in Claude search results. Training crawlers, for example GPTBot and ClaudeBot, are separate settings. Second, content needs direct answers, sources and figures. In the GEO study by Aggarwal and colleagues, adding citations, quotations and statistics gave a relative improvement between 30% and 40% on the main visibility metric. Keyword stuffing gave little to no improvement. Finally, measurement changes. A ranking report cannot show whether ChatGPT names a business. Bing Webmaster Tools added an AI Performance report with citation counts across Microsoft Copilot in February 2026. ChatGPT tags referral traffic with utm_source=chatgpt.com, so those visits can be counted with Google Analytics.
GEO specialist vs SEO agency: how do they compare?
A fair comparison is a comparison of focus, not of quality, because one provider can offer both services. The table below generalises the typical scope of each type of provider in 2026. Individual providers differ, so check the actual scope in every proposal. The biggest practical difference is the reporting. First, an SEO report usually shows rankings, clicks and traffic, measured with Google Search Console. Second, a GEO report shows mentions and citations for a fixed set of customer questions in ChatGPT, Perplexity, Google AI Overviews and Copilot. According to Google, traffic from AI Overviews and AI Mode is part of the overall search traffic in the Performance report, under the Web search type. As a result, a classic SEO dashboard cannot show, for example, which AI answers mention a business or which competitors appear instead. A complete report in 2026 therefore combines rankings and clicks with mentions per AI platform.
When is an SEO agency the better choice?
An SEO agency is the better first choice when the basics of search are not yet in order. Google Search Central names a site redesign or a new site launch as a great time to hire an SEO, because the site can then be built search engine-friendly from the start, according to Google. The same logic applies to GEO: an AI assistant cites pages which Google or Bing have indexed. Typical signals are important pages missing in a check with Google Search Console, slow templates, broken redirects after a migration, or outdated business details. Local businesses should check the Google Business Profile first, which Google also names in the guidance on AI features. Google writes that a small local business can probably do much of the work itself, with the SEO Starter Guide as step 1. In practice, a small business with a modest website may need a one-off technical check more than a monthly retainer. Ask every provider for both options in 2026.
When is a GEO specialist the better choice?
A GEO specialist is the better choice when a site is already indexed and technically healthy, but AI answers recommend competitors instead. The typical customer question then sounds like a request for advice, for example which agency builds a client portal or which supplier fits a specific budget. Generative engines answer such questions with a handful of names, so one mention wins attention in the whole answer. Research supports a focus on content quality over ranking position alone. The GEO paper was presented at KDD 2024. In the paper, the Cite Sources method raised visibility by 115.1% for websites ranked fifth in Google, while the top-ranked website lost 30.3% on average. The authors also found results varied by domain. Finally, the setup was a 2023 lab study on the top five Google results, plus a test with Perplexity.ai showing gains up to 37%. The direction is clear and encouraging for smaller websites: sources and figures earn visibility.
Do you need both GEO and SEO in 2026?
Most businesses need both disciplines in 2026, but not necessarily two separate agencies. Optimizing for generative AI is among the services of an SEO, according to Google, so one agency can cover both. The useful split is by responsibility, not by label. First, one party owns the technical base: robots.txt, indexing in Google Search Console and Bing Webmaster Tools, structured data and page speed. Second, one party owns the question set and the content which answers the customer questions. Finally, one party reports every month on rankings and on AI mentions side by side. When the website is custom software, for example a site built with Next.js or a web app, the developer needs a seat at the table from step 1. Crawler rules, structured data and server-rendered text all live in the code. Two agencies can work well together with one shared question set and one owner for robots.txt.
Which questions should you ask a GEO specialist or SEO agency?
The best questions test method, measurement and honesty, and the hiring checklist from Google is a solid start. First, Google Search Central suggests asking for examples of previous work, the expected results and timeframe, and how success is measured. Second, ask whether every change to the site will be shared and explained. Third, for GEO, Google adds a specific check: whether advice on optimizing for AI experiences aligns with the official guidance of Google Search. During an audit, grant read access to Search Console only, not write access. The GEO questions below complete the checklist for 2026. Compare the answers from at least 2 providers side by side, with Google guidance as the benchmark. A good provider names the platforms, for example ChatGPT and Copilot, the crawlers and the measurement method without hesitation. A company which clearly explains the intended work makes the choice easy.
What are the red flags when hiring for GEO or SEO?
A promised fixed spot in ChatGPT is the clearest red flag, because the model composes every answer itself. ChatGPT ranks search results using multiple factors intended to help users find relevant, reliable information, according to OpenAI. Google warns in the same way about SEOs who claim a #1 ranking or a special relationship with Google. A second red flag is keyword stuffing, which the GEO study found gives little to no improvement in generative engine answers. A third red flag is selling a single file as the solution. An llms.txt file written with Markdown is cheap and can help as a summary, but Google states no new machine-readable files or AI text files are needed for AI Overviews and AI Mode. Paid shortcuts are a fourth red flag in 2026. Ads in ChatGPT run on separate systems and do not influence the answers. For example, an offer of a top spot in ChatGPT for a fixed monthly fee deserves extra questions.
How does VirtuoLab approach GEO?
VirtuoLab (virtuolab.dev) is a software agency in Papendrecht, and GEO optimization is one of the services. Step 1 is a baseline: a fixed question set, the current mentions per AI platform, and a scan of crawler access, for example the rules for OAI-SearchBot and PerplexityBot. Step 2 is the foundation: crawler rules for AI platforms, an llms.txt summary, structured data, Bing Webmaster Tools from Microsoft, IndexNow and consistent business details. Step 3 is answer content around the questions from the baseline. Finally, step 4 asks the same questions every month and compares the results with the baseline. Because the VirtuoLab developer also writes the content, technical fixes with Next.js and the content work stay in the same hands. VirtuoLab helps businesses get mentioned sooner and more often in AI answers. A fixed price follows after a free intro call and the baseline. The VirtuoLab website runs on the same setup in 2026, with public crawler rules for anyone to inspect.
Frequently asked questions
Is GEO the same as SEO?
GEO is not the same as SEO, but GEO builds on SEO. First, SEO aims for higher positions and clicks in the results of Google and Bing, measured with Google Search Console. Second, GEO aims for mentions and citations inside AI answers from ChatGPT, Perplexity, Copilot and Google AI Overviews. The technical base is shared: according to Google, a page needs to be indexed and eligible for a snippet to appear as a supporting link in AI Overviews. The differences sit in the details, for example separate AI crawlers such as OAI-SearchBot, content written as direct answers with sources, and measurement on a fixed question set, as in step 1 below. Good Google rankings therefore do not automatically lead to a mention in ChatGPT. According to OpenAI, ChatGPT works with third-party search providers and ranks results using multiple factors of its own. A useful report in 2026 shows rankings and AI mentions side by side.
What does a good GEO specialist deliver?
A good GEO specialist delivers the work that makes a business easy to recommend: crawler access, answer content with sources, consistent business details and honest monthly measurement. First, the specialist checks how ChatGPT from OpenAI, Perplexity and Copilot answer 15 to 30 customer questions today. Second, the specialist opens access for search crawlers such as OAI-SearchBot and PerplexityBot. Third, the specialist writes or improves pages that answer each question in the first sentence, with figures and sources. Finally, the same questions return every month, as in step 2 of the measurement routine below. ChatGPT ranks search results using multiple factors intended to help users find relevant, reliable information, and ads run on separate systems, according to OpenAI. For example, a solid proposal for 2026 lists activities, platforms and measurements per month. VirtuoLab helps businesses get mentioned sooner and more often, with Next.js for the technical work and the content in one hand.
How do you measure whether GEO works?
GEO works when a business is mentioned more often for a fixed set of customer questions over several months. Step 1 is a baseline: 15 to 30 realistic questions, asked in ChatGPT, Perplexity, Google AI Overviews, Copilot and Claude. Step 2 is repeating the exact same questions every month, because AI answers vary per attempt. Additionally, add hard data. For example, ChatGPT adds utm_source=chatgpt.com to referral links, so visits from ChatGPT can be tracked with Google Analytics. Since February 2026, Bing Webmaster Tools reports citations across Microsoft Copilot and Bing AI summaries, with citation share added in June 2026. Server logs show which pages OAI-SearchBot, PerplexityBot and Claude-SearchBot read. Google Search Console counts AI Overviews traffic inside the regular Performance report, under the Web search type. Together, the data sources show a trend instead of one lucky screenshot.
