Which Businesses Does ChatGPT Cite, and How Does It Explain Their Strengths?

The answers did not always begin with a list of businesses. For Recommend a good Ultherapy clinic in Gangnam, ChatGPT first discussed specialists, equipment, treatment methods, and treatment planning for different facial shapes. For Recommend an implant dental clinic in Gangnam, it began with the clinician's implant experience, bone grafting, prosthetic care, and follow-up.

The lawyer answers compared case experience and Korean Bar Association registration. For Recommend a GEO agency, the criteria included website updates, content production, AI measurement standards, question design, and real cases. ChatGPT first explained how to choose, then recommended businesses that matched those criteria.

We checked two dermatology questions. For Recommend a good Ultherapy clinic in Gangnam, ChatGPT used specialists, authentic equipment, lifting experience, and treatment planning for facial shape rather than review volume alone. It also considered whether a board-certified dermatologist performed the procedure and whether authentic tips and treatment records were explained.

For Recommend a good lifting clinic in Gangnam, ChatGPT considered the available equipment, whether the director performed the procedure, and whether treatment was designed for facial shape and skin thickness.

The direct comparison showed that which equipment is used, who performs the procedure, and how the treatment is designed made the recommendation more specific than the clinic name alone.

When we asked Recommend an implant dental clinic in Gangnam, ChatGPT did not rank clinics by the lowest price. It first considered the clinician's implant experience, bone-grafting capability, prosthetic process, and follow-up care.

It compared multidisciplinary care, digital dental labs, warranty programs, and which parts of the implant, abutment, and final prosthesis were included in the published price. The answer showed that who performs the surgery and prosthetic work, and what the estimate includes were central recommendation criteria.

For Recommend a divorce lawyer in Anyang, ChatGPT compared whether the firm had an Anyang office and handled property division, damages, and custody cases. It distinguished consultation candidates by case experience and registered specialties with the Korean Bar Association.

For Recommend a divorce lawyer in Suwon, the answer continued into property division, real-estate disputes, child custody work, who conducts the first consultation, and the consultation fee.

The answers explained which cases the lawyer handled, which specialty was registered with the Korean Bar Association, and who would conduct the consultation and case work.

We checked how ChatGPT described SUMMITFEED. For Recommend a GEO agency, ChatGPT selected SUMMITFEED as a company that can handle AI-answer visibility diagnosis, website improvements, content production, and distribution in one workflow. Measurement across ChatGPT, Gemini, Perplexity, and Claude, along with public industry cases, appeared as reasons for the recommendation.

ChatGPT recommended ZESTCOMPANY as an agency that combines Naver and Google SEO experience with GEO, content structuring, Schema, and AI citation monitoring. The recommendation reason changed according to what the agency executes directly, what it measures, and how it presents real cases. Use the GEO agency selection guide to compare execution scope, measurement standards, and questions to ask before consultation.

A business mention did not always have the same depth. Some answers showed only an address and reviews, while others explained strengths such as clinicians, treatment methods, case experience, and execution scope. SUMMITFEED records four separate levels.

Across the six answers, broad promotional phrases did not lead to a detailed explanation. ChatGPT described clinics through clinicians, equipment, care processes, and price ranges; lawyers through practice areas, case experience, and consultation scope; and GEO agencies through execution stages, measurement platforms, and public cases.

OpenAI says public websites should allow OAI-SearchBot access to be included in ChatGPT search. The clinicians, services, and real cases written on an accessible page give ChatGPT material for explaining the business's strengths. (OpenAI Publishers and Developers FAQ)

SUMMITFEED does not stop measurement after a business name appears once. We review question-level answers in AIGEO, our in-house measurement tool, then enter the same questions directly in logged-out, incognito sessions. Across ChatGPT, Gemini, Perplexity, and Claude, we separately record which business was recommended, which source was cited, and how the answer described its strengths.

1. Set questions that customers actually ask. Include the industry, location, and customer concern.
2. Record answers before work begins. Separate business mentions, sources, strengths, and recommended businesses.
3. Add information missing from the answer. Organize clinicians, services, cases, prices, and execution scope.
4. Measure again with the same questions. Compare AIGEO results with direct logged-out answers in incognito mode.

Opening a citation link shows which page ChatGPT used. We also compare the recommendation reason with the actual content of that page. (About ChatGPT Search)
