Clinic Website Loading Speeds: Are Only 10% Meeting Google Standards? Independent Survey of 300 Clinics Nationwide

## "Clinic Marketing Blueprint" (operated by SUTEKi Inc., Utsunomiya City, Tochigi Prefecture), a service specializing in SEO for clinics, conducted an independent survey on mobile loading speeds (Core Web Vitals) for 300 clinics across 30 prefectures and 10 medical departments.

The findings show that only 10.2% of clinic websites meet Google's recommended "Good" standard, revealing that most sites have significant room for improvement. In response, SUTEKi is releasing 10 systematic improvement guide articles for free.

### 77% of 300 Clinics Rated "Poor" by Google, Average LCP 5 Times Higher than Standard

An investigation into Largest Contentful Paint (LCP), one of the Core Web Vitals used as a search ranking factor since 2021, found that 193 out of 251 measurable clinics (76.9%) fell into the "Poor" category (over 4 seconds).

The average LCP was 12.25 seconds, approximately five times higher than Google's recommended "Good" standard (2.5 seconds or less). Even the median was 8.52 seconds, indicating that patients searching for medical care are likely to experience stress when opening clinic websites.

### Orthopedics Ranked Slowest; 0% Achieved Good in All Core Web Vitals

Analyzing average LCP by department, Orthopedics was the slowest (average LCP 17.25 seconds), and 0% of clinics in this department achieved "Good" in all Core Web Vitals items.

Followed by Otorhinolaryngology (16.66 seconds) and Ophthalmology (14.84 seconds), indicating that departments with high image-to-text ratios struggle with website loading speed.

### Even the Fastest Departments Failed to Meet Google Standards

Conversely, the fastest average LCPs were found in Psychosomatic Medicine (7.55 seconds), followed by Internal Medicine (8.13 seconds) and Psychiatry (8.40 seconds). However, none of these met Google's "Good" standard (2.5 seconds or less).

### The Importance of Perceived Speed in Medical Search

In recent years, patient behavior has solidified into "search symptoms -> compare top-ranking websites -> call or book." Website loading speed influences both SEO ranking and patient bounce rates.

Since "Poor" websites with an LCP of over 4 seconds are at a disadvantage in Google search rankings, the results of this survey suggest that many clinic websites have room for improvement in perceived speed for medical searches.

### Releasing 10 Free SEO Systematic Guide Articles

Alongside this survey, SUTEKi has released "10 Systematic Guide Articles for Clinic Patient Acquisition" for clinic directors, covering five categories: SEO, MEO, Website Production, Medical Advertising Guidelines, and KPI Design.
