YMYL (Your Money or Your Life) websites are websites that have the potential to affect your health, happiness, finances, safety, or life.

Examples of YMYL pages such as financial consulting websites, hospital websites, legal service companies’ websites, etc.

Because depending on the feelings of each person will evaluate the flowers that Google offers may be beautiful or not. These search results have almost no impact on your interests or health.

However, if you are looking to use Paracetamol, then E-A-T plays an extremely important role. If Google gives inaccurate results, written by copywriters or writers but not verified and authentic. This information is very easy to influence the reader. Because this content is not professional and is not verified, when applied, it will threaten human health and life.

Therefore, if your website belongs to YMYL, it is even more important for Google to build Content Marketing that meets E-A-T standards. Below, I will show you how to apply E-A-T to build sustainable Content Marketing.

How To Build Sustainable Content Marketing According To E-A-T Standards

In order for the content on the website to be used in a long-term and sustainable way, it must first ensure quality and bring value to readers. And according to the Search Quality Rating Guidelines, E-A-T is one of the essential criteria for assessing the quality of a website. So how to build sustainable Content Marketing, meeting the 3 criteria of E-A-T?


According to the original definition, expertise is the in-depth knowledge of a particular field. However, professional knowledge is not enough to help your website get sustainable traffic.

Keyword research to know what your customers are searching for and understand the user intent behind each of those terms.

Then use your insights to answer their questions and strive to deliver information that exceeds your customers’ expectations.

In addition, behind each search term, there will be many types of perceptions about different information and products (unknown, learned, experienced…). The task of an expert is to convey information (through content marketing) to users in the most understandable way (without using too many specialized or figurative terms). So that even those who do not know anything still understand and grasp your content.

Depending on the type of website, the appropriate expertise will be applied:

With YMYL pages, we must specialize content, 100% accurate: legal, health, medical, financial…

For example: With the keyword how much is the fine for running a red light. The content needs to ensure accurate information by following the issued laws and decrees.

For non-YMYL sites that need more daily professional knowledge or personal experience: experience sharing website, the website is a forum…

Example: With the keyword sunscreen review. Content is not required to show exactly what is inside. But you definitely have to give your personal feelings after using it.

Finally, you should not hesitate to internally link articles on the same topic together to make it easier for users to access. This is also a way to help your website become a complete, accurate, and highly specialized source of information with much in-depth analytical content on the same topic.


The first element of authority for content on your website is that you have to prove an expert on your own content. To do this, you must first show your customers who owns this content, and what level of expertise the author has… by:

Create transparency and clarity for the author part

Each article should clearly state the author’s full name, not a generic name like Admin.

Add an introduction about the author: if the author of the article is an expert in their field, you need to show it to your customers and Google through referrals.

In addition, in order for Google and users to verify the information in the introduction and the qualification and authority of the author, you should put links or contact information such as: email, social network links… Authors.

After ensuring clarity for content owners, you can apply the following additional ways to improve the Authority factor for posts:

Cite Reputable Sources For The Article

Because when a user reads content with clear and transparent evidence. They will easily verify the origin of the information, helping to increase trust in that content and the brand.

Building Links From Competent Individuals And Organizations

Not to mention E-A-T, when a website receives backlinks from reputable websites is already a big plus to improve its ranking position on Google. Meanwhile, to evaluate the Authority factor in EAT, Google mainly relies on links coming from high authority sites such as: government sites, and reputable organizations (hospitals, large clinics). , research institutes…).

In addition, getting backlinks from influential individuals in a field is also a way to increase the authority of your content.

Mentioned On Sites Like Wikipedia

In addition to the backlink factor, being mentioned on sites like Wikipedia will help your business become more reputable and trustworthy. However, to appear on these sites, your content must be qualified and you must have a voice in your industry.


Trust in content is often demonstrated through customer experience with the content itself. Include UX/UI and quality elements within the content. Therefore, reliable content on the website should first ensure accuracy. Then combine it with other ways to increase the credibility of the website.

Regular Content Updates

We need to update the content regularly on the website. Because over time, your content will gradually become outdated, no longer relevant to the present. So when customers access it, it will be difficult to put their trust in the information that is no longer accurate. Besides, Google always wants to bring users the newest and quality information. Old content can hardly stand on the search results rankings, being replaced by better content.

Some ways to update content to improve the E-A-T of articles include:

  • Updated by someone with more expertise and authority.
  • Add citations, data from experts, and reputable websites.
  • Correct errors in grammar, spelling, and article structure.
  • Add new information to make the content more insightful and unique.
  • Add more attractive images and charts, and optimize according to SEO standards.

Increase Positive Business Reviews

Having too much negative feedback on your website or business-related media is a signal that your business, brand, and website quality is poor.

Therefore, you should enhance the good reviews for the business on the content of articles, social networks, Google My Business, and trusted websites in the industry.

Full Display Of Business Information

Websites that do not provide customers with contact information are considered unreliable sites. Especially for YMYL pages, contact information is essential and important.

So to increase customer trust in your website, you need to add at least some basic contact information such as contact address, phone number, email, etc.

In addition, you can apply the following ways to increase customer trust:

Use an HTTPS address to increase site security.

Provide customers with a commitment to their information security when accessing the website.

If it is a product description, you should provide complete and accurate information about the product to the customer.

If it is knowledge-sharing content, you need to be transparent and clear about who the author is, and where you can take the citation information from…
