Case #1 Health / Dental Clinic

A Dental Clinic in Kadıköy

Istanbul, Kadıköy — 1 dentist, 8-year-old clinic

Before GEO
  • ✗ Never appeared in ChatGPT, Gemini, or Copilot for the query "dental clinic in Kadıköy"
  • ✗ No Schema.org structured data on the website
  • ✗ Google Business Profile hours were out of date, no photos
  • ✗ No FAQ page; service descriptions were one-line headings
  • ✗ No llms.txt
After GEO (week 6)
  • ✓ ChatGPT and Copilot recommend the clinic for "dental clinic in Kadıköy"
  • ✓ MedicalClinic + FAQPage JSON-LD added (8 Q&A pairs)
  • ✓ GBP completed: 12 photos, current hours, service list
  • ✓ 5 blog articles on topics like "implant prices" and "booking an appointment"
  • ✓ /llms.txt and instant Bing notification via IndexNow

Visibility by Platform

Perplexity

After: ⚠️

💡 What we learned from this case

The missing GBP directly affected Gemini — Gemini visibility was zero until GBP was completed. Once FAQPage schema was added, ChatGPT started citing the clinic directly for questions like "what are this clinic's hours?" Perplexity took 8+ weeks and more external sources (directory listings) for full visibility.

Case #2 Legal / Law Firm

A Criminal Defense Law Firm in Ankara

Ankara, Çankaya — 2 partner lawyers, 15-year-old firm

Before GEO
  • ✗ Not present in AI for queries like "criminal lawyer Ankara" or "lawyer recommendation Ankara"
  • ✗ Static HTML website, no Schema.org, no SSL certificate (http://)
  • ✗ GBP listed as "law firm" category instead of "lawyer"
  • ✗ Practice areas (criminal law, felony defense) weren't clearly stated anywhere
After GEO (week 4)
  • ✓ ChatGPT started recommending the firm for "criminal lawyer in Ankara"
  • ✓ SSL (https) obtained; LegalService schema + practice areas added
  • ✓ GBP category updated to "Lawyer", 10 real photos added
  • ✓ "How does a criminal case proceed?", "What does hiring a lawyer cost?" — 6 FAQs

Perplexity

💡 What we learned from this case

The HTTP → HTTPS switch had the fastest impact; Bing's crawl frequency rose noticeably in the first week after the SSL switch (notified via IndexNow). In the legal field, AI engines want practice areas clarified precisely — not "lawyer" but specific entity clarity like "criminal defense lawyer, Ankara Çankaya" is essential. All 4 platforms gained visibility by week 4, the fastest result among these cases.

Case #3 Food & Beverage / Restaurant

A Seafood Restaurant in Izmir

Izmir, Alsancak — 45-seat venue, 6-year-old restaurant

Before GEO
  • ✗ Didn't appear in AI queries for "seafood restaurant in Izmir"
  • ✗ No food photos on GBP, no menu added
  • ✗ Website was a single-page HTML with just a mobile number and address
  • ✗ Missing Zomato and TripAdvisor listings
  • ✗ NAP in the wild: 3 different phone numbers across 3 platforms
After GEO (week 5)
  • ✓ ChatGPT and Gemini recommend it for "seafood in Alsancak, Izmir"
  • ✓ GBP: 28 food photos, full menu, reservation link added
  • ✓ Restaurant schema + servesCuisine + hasMenu + reservations added
  • ✓ Zomato + TripAdvisor listings completed, NAP aligned
  • ✓ FAQ: "Is a reservation required?", "Is there parking?", "What's the price range?" etc.

Copilot

After: ⚠️
Perplexity
Before: ❌
After: ✅

💡 What we learned from this case

NAP inconsistency (3 different phone numbers) was the single biggest factor blocking AI visibility. The impact of other steps stayed limited until it was aligned. The servesCuisine field in the Restaurant schema was critical for Gemini — it fully matched the "seafood in Izmir" query. Copilot needed a Bing Places listing; GBP alone wasn't enough for Copilot.
