How We Helped Augenarztzentrum Zürich Achieve 127% SEO Growth

Augenarztzentrum Zurich is one of Zurich's most trusted eye care centers, with ophthalmologists handling everything from routine check-ups to cataract surgery and laser treatments.

However, the clinic was nearly invisible for the searches that mattered. The treatments were there, the reputation was there, but the pages just weren't showing up where patients were looking.

So we got to work.

Where 
they started

A clinic with over a dozen specialist treatments, experienced surgeons, and a loyal patient base. But only 63 keywords are sitting in Google's Top 3. For a practice this broad and this good, that number should have been way higher.

So what was going wrong?

After our initial audit, we identified three core issues:

1. Technical Barriers Across the Website

The site suffered from:

  • Inconsistent and messy heading structures (H1-H6 hierarchy issues)
  • No structured data implementation
  • Weak internal linking logic
  • Poor semantic segmentation of service content

Search engines could crawl the site, but they couldn’t clearly understand it.

2. Under-Optimized Service Pages

Service pages lacked:

  • Clear answer-first structure
  • Extractable summaries
  • FAQ sections
  • Intent-aligned headings
  • Entity clarity for modern semantic search

For a medical institution operating in a highly competitive local market, this created a significant visibility gap.

3. Missed Opportunities in AI & Generative Search

In all of 2024, the clinic had just 47 AI-referred views. With AI-powered search tools like Google's AI Overviews reshaping how people find medical providers, that was a massive missed opportunity.

The clinic had earned its authority in the real world.

The website simply wasn't reflecting it.

What we built

Based on our findings, we built our strategy around a technically sound, semantically structured, and AI-ready search ecosystem.

Here’s how it looked in practice:

1. Technical SEO Audit & Structural Fixes

Before we touched a single word of content, we began with a full-scale technical audit.

That means: 

  • Rebuilding the heading hierarchy across core pages
  • Implemented relevant structured data
  • Ensured search engines could clearly interpret page intent
  • Removed structural inconsistencies that diluted ranking signals

This laid the foundation for sustainable ranking growth.

2. Service Page Optimization (Semantic + AI-Ready Structure)

Next, we restructured and optimized high-value service pages.

Each page was rebuilt to:

  • Follow a logical semantic flow (Problem → Solution → Process → CTA)
  • Include direct-answer sections
  • Add FAQ modules aligned with user intent
  • Improve readability for patients
  • Ensure AI tools can extract accurate medical summaries

With these changes, the website became easier to understand for both patients and search engines.

3. Internal Linking & Authority Flow

We implemented a strategic internal linking framework that:

  • Strengthened authority flow to high-converting service pages
  • Connected related treatments (e.g., dry eyes, glaucoma, cataracts)
  • Reduced orphan pages
  • Improved contextual reinforcement between topics

Instead of isolated pages, the website became a structured knowledge ecosystem.

The Results

Keyword Performance

  • Top 3 keyword rankings increased from 63 → 143 (+127% growth)

More high-intent service keywords now rank in the most visible positions, improving discovery for core treatments.

All within one year.

AI & Generative Search Visibility

  • AI-referred views increased from 47 → 605

Augenarztzentrum Zürich now ranks more consistently for high-intent, treatment-focused keywords in Zürich.

The website structure better reflects the clinic’s medical expertise, making it easier for both search engines and patients to understand the services offered.

Organic search is now a stronger acquisition channel, with improved positioning across core service areas.
