GEO AGENCY GUIDE

GEO Agency Selection CriteriaHow to choose a company that really does GEO

GEO is not simply publishing content. You must be able to design the citation structure of ChatGPT·Gemini·Perplexity·Claude, Schema Markup, JSON-LD, brand entity, authority, and AI Visibility measurement together.

WHY IT MATTERS

GEO agencies suddenly increased

After 2024, as generative AI search and AI Overview, Perplexity, and ChatGPT Search spread, many SEO companies and marketing agencies began talking about GEO services. However, not all agencies have actual GEO capabilities.

GEO is a strategy that combines traditional SEO, content marketing, technical SEO, Schema Markup, brand entity, external provenance building, and AI Visibility measurement. It is difficult for a brand to be cited reliably in AI answers simply by writing a lot of blog posts or repeating keywords.

A good GEO agency is not a company that says, “I’m exposed to AI,” but one that can explain in which questions, on which platforms, and with what source structure your brand should be cited.

SELECTION CRITERIA

GEO 8 strict criteria for choosing an agency

01

Do you actually understand the citation structure for each AI platform?

ChatGPT, Gemini, Perplexity, Claude do not all answer the same way. ChatGPT values ​​brand entities and structured documents, while Gemini strongly reflects the Google search ecosystem and E-E-A-T trust. Perplexity looks at real-time search and authority-based sources together, while Claude prefers long, professional documents and logical structures. A good GEO agency should be able to separate these differences into platform-specific strategies.

02

Can you design Schema Markup and JSON-LD?

GEO is not complete with content alone. In order for AI and search engines to clearly understand the brand, schemas such as Organization, Service, Article, FAQPage, BreadcrumbList, LocalBusiness, and Product must be designed to fit the situation. If an agency that can't handle JSON-LD at all says GEO, they most likely lack technical GEO capabilities.

03

Is it possible to build a brand entity?

AI understands entities beyond simple keywords. The brand is recognized as a single information unit when the company name, service name, representative service, industry, region, FAQ, and external references are consistently connected. GEO Agencies must design their brands not as search terms but as Entity Graphs that AI can understand.

04

Do you understand the authority structure of Perplexity?

Perplexity does not simply cite the latest content. We evaluate reliable sources such as official websites, media, professional media, research materials, communities, and external references. Therefore, GEO agency should be able to propose a strategy to build authority not only through internal content on the website, but also through external mentions, press releases, and distribution of professional content.

05

Can you design content rather than produce content?

Many companies emphasize monthly issuance volume, but AI does not evaluate simple issuance volume. What matters are responsiveness to questions, evidence, expertise, structure, and sources. Good GEO content should be designed based on Question, Answer, Evidence, and Structure, and should be in a form that is easy for AI to quote while directly answering the user's actual questions.

06

GEO Is there a performance measurement system?

GEO should not be operated by intuition. You should track how often your brand appears in AI answers and on what platforms it is cited through metrics such as AI Visibility, Citation Rate, Share of Voice, Mention Volume, and Platform Coverage. At a minimum, even for manual measurements, there should be a list of targeted questions and a record of responses for each platform.

07

Do you understand the relationship between Google SEO and Gemini?

Since Gemini is connected to the Google search ecosystem, the existing SEO base is very important. Index status, Search Console, Core Web Vitals, E-E-A-T, content quality, and structured data must be in place to increase the chances of your brand being discovered in Gemini-based AI answers.

08

Does it refer to long-term authority accumulation rather than short-term citation guarantee?

GEO is not structured to be set today and become number one tomorrow, as advertised. AI citations depend on content quality, source credibility, external mentions, update frequency, and competitor status. Rather, you should be cautious about proposals that unconditionally expose you to ChatGPT right away.
