What is the Health Update? : Explaining Web Operation Points for Medical and Health Websites

Health update

In fact, according to the Ministry of Health, Labour and Welfare, Japan’s medical expenses reached approximately 43 trillion yen in 2020, and are expected to rise to about 62 trillion yen by 2030. Additionally, the healthcare industry, including supplements, had a market size of about 25 trillion yen in 2016, which is forecasted to expand to about 33 trillion yen by 2025.

Given this increasing focus on the medical and health sectors in Japan, which has a significant impact on national life, websites operating in this field must disseminate accurate information more diligently than those in other sectors.

Furthermore, web managers in this field need to be aware of Google’s “Health Update” conducted in 2017 to be properly evaluated in SEO .

This time, we will explain the reasons behind this update, what aspects to be careful about to be accurately evaluated by search engines, and other key points.

What is the Health Update? 

The Health Update refers to an update implemented on December 6, 2017, specifically for “medical and health-related search results” in Japan. Unlike updates like the Penguin Update that targeted all countries, this was an unusual update implemented only in Japan.

Following this update, medical and health websites that are deemed less trustworthy have seen a decline in rankings, whereas those disseminating information from experts, medical institutions, or official agencies with credible evidence have tended to rise in rankings.


Background of the Health Update 

There are two main reasons for implementing the Health Update.

The first reason is the increased opportunity for Japanese people to gather health-related information via the internet. Indeed, according to the “2014 Health, Labour and Welfare White Paper” published by the Ministry of Health, Labour and Welfare, there has been a significant increase in the frequency of internet contact for health information.

The second reason can be attributed to the 2016 “WELQ scandal” that was widely covered by online media. This incident involved the major internet company DeNA, which was found to be posting a large number of low-quality health-related articles, eventually leading to the closure of the site.

Despite the fact that many Japanese people use the internet to collect medical and health-related information, there is a risk of health damage to the general public if websites posting incorrect information such as “eating this cures diseases” are ranked highly.

These reasons led to the implementation of the Health Update in Japan.

Impact of the Health Update on Search Results 

According to Google, about 60% of health and medical-related keywords are affected by the Health Update.

The update has had a positive impact on credible websites provided by medical professionals and experts, resulting in an upward trend in search rankings. Specifically, websites of medical institutions (eg, hospitals), websites operated by medical professionals (eg, pharmaceutical companies), and government websites (eg, Ministry of Health, Labour and Welfare) are included.

On the other hand, websites whose rankings have declined typically share the following characteristics

  • Affiliate links
  • Lack of evidence and low credibility
  • Information not directly disseminated or supervised by experts
  • Simply compilations of information from other sites

After the Health Update, there is a clear demand for more reliable information in this field.

Benefits of the Health Update 

For web managers who prioritize user needs, the Health Update offers numerous benefits. Here, we outline these advantages

Gaining Industry-Wide Trust 

The medical and health sectors attract the attention of many users. If search results are flooded with false or inaccurate information, the entire industry could lose trust. Conversely, if the information is accurate and useful for users, it enhances the industry’s credibility overall, which can lead to an increase in website visitors and conversion rates.

Accurate Information Reaches Users

If users mistakenly believe incorrect information to be accurate, it can lower the credibility of websites that were originally providing correct information.

For example, if one piece of incorrect health information spreads among users, websites that were providing correct information might be perceived as erroneous. The Health Update reduces the likelihood of such confusion, ensuring more accurate information is conveyed.

Focus on Creating Quality Content 

Before the Health Update, companies and individuals who created a large volume of pages with incorrect information often dominated the top of website rankings. Many of these websites were ranked highly due to technical SEO alone and did not necessarily provide useful information to users.

However, after the Health Update, websites operated by those who prioritize reliability and accuracy, and provide quality content useful for users, tend to rank higher. This shift has created an environment where web managers can focus more on producing quality content.

Web Operation Points Considering the Health Update 

Although the Health Update was implemented in 2017, there are still many important points relevant to website management in 2023. Here, we organize these points for you. If you are operating a website related to medical and health sectors, please check the following aspects.

Comply with the Pharmaceutical Affairs Law and the Health Promotion Law 

When operating a medical and health-related website, it is important to comply with the Pharmaceutical Affairs Law and the Health Promotion Law.

The Pharmaceutical Affairs Law pertains to the quality and safety of pharmaceuticals and cosmetics. When disseminating information in these areas, there are strict rules on how information should be presented. For instance, misleading expressions like “this cures diseases” are prohibited.

Additionally, the Health Promotion Law regulates to ensure that consumers are not provided with incorrect health information. For example, claims such as “effective” or “removes blemishes” without any basis are inappropriate.

When operating a medical and health-related website, adhere to these laws and pay close attention to the accuracy and the way information is presented.

Ensure Reliable Citations and External Links 

When creating content, you might cite data or clinical results from other websites. It is crucial to cite from reliable websites.

For example, consider citing from the following sites.

  • The Ministry of Health, Labour and Welfare
  • The World Health Organization (WHO)
  • Academic journals related to medicine and health, such as “The Lancet” and “New England Journal of Medicine”
  • University or research institution websites

Make sure to cite from websites that are known for their accuracy and reliability.

Publish the Latest Information 

When managing a medical and health-related website, also ensure that the information is up-to-date.

In this field, new research findings, insights, technologies, and treatments are constantly being released. What was once considered correct may now be incorrect. Therefore, as a web manager, keep an eye on the latest information to avoid providing outdated content.

Publish Information About Authors and Operators 

Please set up a dedicated page on your website to publicly display information about the operators and authors. Users prioritize knowing who and from where the information originates when judging the credibility and accuracy of a website.

Especially in the medical and health sectors, who is disseminating the information directly affects the accuracy and trustworthiness of that information. As a specific measure, you can communicate the author’s profession, work history, qualifications, and education on a profile page, for instance.

Attach a Supervisor if the Author is Not an Expert 

If the author is not an expert in the medical and health fields, make sure to have the content supervised. For example, if posting an article related to food and diet, seek supervision from a registered dietitian.

The supervising expert should check whether the article content is based on the latest scientific evidence and ensure there are no misleading expressions, making corrections and guidance as necessary.

Communicate in Simple Language 

Accuracy is particularly crucial for websites in the medical and health sectors. However, the users visiting these websites are not necessarily experts themselves. Therefore, merely prioritizing accuracy and using complex terminology can confuse users.

Thus, include annotations for specialized terms and use common words that ordinary people use, like “stomach ache” or “itchy eyes,” when creating content. Creating user-first content is essential, even in the medical and health sectors.
