GEO Audit: Do ChatGPT, Gemini, Perplexity and Copilot Mention Your Brand?

Customers now ask AI before they search Google. Ktdigital’s GEO Audit measures whether your brand appears in those answers, which competitors appear instead, and what to fix first. Led directly by Aiden Hoang Nguyen.

How a GEO Audit Differs From an SEO Audit

An SEO audit answers “how does Google see your website”. A GEO Audit answers a different question: when customers ask AI, does the answer mention you, and if not, where is the AI getting its information?

	SEO audit	GEO Audit
What is measured	Rankings, indexing, speed on Google	Answers from ChatGPT, Gemini, Perplexity, Copilot
Unit of measure	Keywords	Full questions along the customer journey
Main output	List of technical and content issues	Mention rate, citation rate, share vs. competitors

Need both Google and AI covered? See the combined SEO & GEO Audit. Already audited and ready for ongoing work? See GEO services.

Mention rateAcross a fixed question set, how many AI answers name your brand, per platform.

Citation rateHow many answers link to your website rather than to media, forums or competitors.

Share of answersAgainst 3–5 competitors: who AI mentions most, on which questions, and why.

AccuracyWhether AI describes your fees, services, location or other details wrongly or from outdated sources.

💡 GEO Insight

Ktdigital.vn itself has started appearing as a source in AI-generated queries such as which GEO experts businesses can hire in Vietnam. The measurement method in the GEO Audit is tested on the site that runs it.

What the GEO Audit Covers

Six areas, scaled to your brand and target markets.

❓

Customer-journey question set

30–80 real questions customers ask AI, from research and comparison to decision. Vietnamese and English if you serve international markets.

🤖

Measured on 4 AI platforms

ChatGPT, Google Gemini, Perplexity, Microsoft Copilot. Full answers and cited sources are recorded so you can re-check them yourself.

🎯

Competitor benchmark

3–5 competitors of your choice. Who gets mentioned most, on which question groups, and what content they have that you don’t.

🕸️

Technical audit for AI crawlers

Can OpenAI, Google, Perplexity and Bing crawlers reach your site: robots.txt, llms.txt, speed, content hidden behind JavaScript, pages blocked from indexing.

🧩

Schema & brand entity

Organization, product/service and FAQ schema; whether brand facts are consistent across your website, Google Business Profile, press and profile sites.

🗺️

AI sources & 90-day roadmap

The websites AI relies on when answering about your industry, plus actions ranked by impact and effort.

Education sector

GEO Audit for Schools & Admissions Teams

Students and parents now ask AI to build their shortlist before visiting any website. If your school is not in the answer, it is not on the shortlist. These are typical questions I include for education brands:

“Best part-time MBA programs in Hanoi for working professionals”
“Which master’s in management in Ho Chi Minh City offers an international degree?”
“Compare MBA tuition at private universities in Vietnam”
“Best business schools in Vietnam for international students”
“Online or part-time: which programs are accredited?”

Extra checks for education brands

Program pages carry the facts AI likes to cite: duration, tuition, entry requirements, degree, accreditation
EducationalOrganization, Course and FAQ schema on admissions pages
English pages for international admissions, with hreflang between versions
Rankings, accreditation and international partners confirmed by third-party sources
Whether AI is quoting outdated tuition or discontinued programs
Whether multiple sub-sites (institutes, faculties, programs) dilute the brand entity

No English page for the flagship program. Across 20 English questions, School A is mentioned only twice.High impactMedium effort

Frequently Asked Questions

An SEO audit checks how Google sees your website: crawling, indexing, speed, keywords. A GEO Audit checks what AI assistants such as ChatGPT, Gemini, Perplexity and Copilot answer: whether your brand is mentioned, whether your site is cited, which competitors appear instead, and why. The two complement each other; a GEO Audit also includes technical checks specific to AI crawlers.

By actual working hours at USD 25 per hour. Starter is about 18 hours, Standard about 40 hours, Advanced about 40 hours plus 8 hours per month for 3 months of tracking. After a free scoping call you receive a fixed quote before any work starts.

With an individual. I work as an independent consultant, not an agency, so the person on the call is the person doing the audit. I sign a service contract covering scope, deliverables, timeline, acceptance and confidentiality.

No. As an individual consultant I do not issue VAT invoices. I provide a service contract, an acceptance record and payment receipts. If your organization requires a VAT invoice, please tell me before I start.

Yes. Confidentiality is part of the service contract and I am happy to sign a separate NDA on your template. Search Console, GA4 data and audit results are used only for the project.

Starter takes 5 to 7 working days and Standard 10 to 14 working days, counted from when the question set is agreed and access is granted. Advanced adds 3 months of tracking with monthly reports.

No. An audit is a diagnosis: it measures the current state, explains the causes and ranks the fixes. Nobody controls what AI assistants answer. What I commit to is a transparent, repeatable measurement method so you can verify progress yourself after implementation.

Your priority products, services or programs, 3 to 5 competitors to benchmark, and your target markets and languages. For Standard and above: read access to Google Search Console and GA4 if available.
