The assumption
Most clinic owners assume that if they rank well on Google, they'll automatically appear in AI answers. It's a reasonable assumption — but it's wrong.
Google Search and AI platforms like ChatGPT, Claude, Gemini, and Perplexity are fundamentally different systems. They use different data sources, different ranking signals, and different output formats. Success in one doesn't translate to success in the other.
How Google works
Google ranks web pages in a list. The ranking is driven by on-page keywords, backlink authority, technical site health (speed, mobile-friendliness, core web vitals), and user engagement signals. The output is a ranked list of links that you click through to visit.
This system has been the primary discovery channel for aesthetic clinics for over a decade. Most clinics have invested significantly in SEO to maintain their Google rankings.
How AI platforms work
AI platforms don't rank pages — they generate answers. When a patient asks "Where should I get cheek filler in Belfast?", ChatGPT doesn't return a list of links. It returns a paragraph naming specific clinics with descriptions of why they're recommended.
The data behind these answers comes from training data (a snapshot of the web from a specific date), real-time web access (for platforms that support it), structured data and schema markup, and citations from authoritative sources.
None of these are the same as Google's ranking factors. A clinic's backlink profile, page speed score, and keyword density are largely irrelevant to whether AI mentions them.
Real examples from our audit data
In our Belfast audit, several clinics that rank on page one of Google for competitive treatment terms had zero AI visibility — no mentions across 287 prompts on four platforms.
Conversely, some clinics with modest Google rankings appeared frequently in AI answers because they had strong entity data, good schema markup, and mentions in authoritative directories.
The correlation between Google ranking and AI visibility is weak. They measure different things.
Why you need both
This isn't an either/or situation. Google still drives significant traffic, and SEO remains important. But AI search is a separate channel with its own rules, and ignoring it means leaving a growing source of high-intent patients on the table.
The good news is that some actions — like improving structured data and building authoritative citations — benefit both channels. Learn more about how AI visibility and SEO compare.
