The Healthcare Directory Stranglehold

For over a decade, Greek patients searching for doctors faced a simple reality: healthcare aggregators controlled page one of Google.

Google SERP: Directory Dominance

Google SERP Top 10 Doctors - Doctoranytime dominates at 88%

Doctoranytime captures 88% visibility - appearing in 44 of 50 queries. Individual doctors fight for the remaining 12%.

The Traditional SEO/Directory Model Required:

  • >Constant content production (20+ articles/month)
  • >Years building domain authority to outrank aggregators

The AI Revolution: How LLMs Leveled the Playing Field

When we analyzed ChatGPT's responses to the same 50 healthcare queries, the traditional hierarchy shattered.

The Reversal Is Complete

Independent doctors and small clinics now occupy 9 of the top 10 positions in ChatGPT. Doctoranytime dropped from 88% (Google) to 23% (ChatGPT) - a 74% collapse in visibility dominance.

The Channel Overlap Crisis

Only 21.2% of doctors appear in both Google and ChatGPT results. This is healthcare discovery democratization in action.

Channel Overlap - 21.2% overlap rate between Google and ChatGPT
DistributionGoogle OnlyBoth ChannelsChatGPT Only
Number of Doctors2949153
Percentage12.6%21.2%66.2%

Critical Finding: 66% of doctors recommended by ChatGPT are invisible in Google's top 10. Traditional SEO/directories reach only 1/3 of discoverable doctors. Patients using only Google miss 153 qualified practitioners.

Citation Source Diversity

AI platforms draw from significantly more sources than traditional Google, giving smaller practices equal footing.

Unique Domains Cited per Platform

Citation Source Diversity - ChatGPT cites 139 domains, Perplexity 114, Google AI only 38

More sources = more doctors discoverable. Google's ~10 top domains create winner-take-all dynamics.
