Eye Clinic Case Study: How AI Marketing Delivered Results in Kolkata

Real case study: a Kolkata-based eye clinic practice increased leads with AEO. Before/after metrics inside.

# Case Study: Eye Clinic in Kolkata Wins with AI Marketing

The Challenge

A well-established eye clinic practice in Kolkata offering LASIK surgery, cataract removal, and glaucoma treatment (Rs 10,000-1,00,000) was losing patients to Centre for Sight and other chains that dominated AI search results.

Despite strong Google reviews and years of experience, asking ChatGPT or Perplexity for "eye clinic in Kolkata" returned zero mentions of their practice.

What We Did (90-Day Sprint)

Month 1 — Foundation

  • Implemented full schema markup (services, pricing, practitioner bios)
  • Created 15 FAQ pages targeting exact AI queries
  • Unblocked AI crawlers and added llms.txt

    • Month 2 — Content

  • Published 8 long-form guides on LASIK surgery and cataract removal
  • Listed on 12 niche directories that AI models trust
  • Built patients testimonial pages with structured review data

    • Month 3 — Acceleration

  • Earned mentions in 3 local health/business publications
  • Created comparison content vs. chain competitors
  • Optimized for voice and conversational queries

    • Results After 90 Days

  • AI citations: From 0 to appearing in ChatGPT, Gemini, and Perplexity answers for 12 key queries
  • Organic leads: 40% increase in website contact form submissions
  • Phone calls: 28% uplift in calls attributed to organic/AI channels
  • Revenue impact: Estimated additional monthly revenue from new patients at Rs 35,000 avg ticket

    • Key Takeaway

    The practice went from invisible in AI search to being the recommended eye clinic in Kolkata. Total investment paid for itself within 8 weeks.
