Significance of the semantic core for a medical website

The semantic core plays a crucial role in the search engine optimization of websites, and if you have just started to digitalize your business, this article will be very useful material for you.

What is SEO?

Search engine optimization (SEO) is one of the main methods of website promotion on search engines. In other words, optimizing a website for a search engine:

  • increases its visibility in search engines
  • places it in a leading position
  • supports organic conversion (impression-click ratio)
  • increases website credibility in the market (local or international)

In this article, I would like to dwell on a narrow concept — the Semantic core, as well as talk about the rules of its formation for the medical business. Often, its quality is neglected, but it is the starting point in optimizing a website for the medical field.

First of all, it will be useful to know the owners of medical institutions, clinics, private specialists, or specialists working in the field of Internet marketing for medicine.

What is a semantic core, and how is it formed?

What is the Semantic core?

The semantic core is a huge list of keywords that describe your business, services, and all the queries that a user enters in the Google search bar to get information about your business.

Key queries have characteristics:

  • frequency (high-frequency, mid-frequency, low-frequency, super-low-frequency);
  • type (commercial, informational);

The frequency characteristic speaks for themselves: the more users enter a key query into the search bar, the higher its frequency. And vice versa.

Difference in frequency of keywords in semantic core for healthcare industry

The movement of the orange line to the right in the chart above is called the Long Tail. With the development of medicine and any other market, the number of keywords in the orange zone will increase infinitely, and their frequency constantly strives to 1.

Gathering the semantic core for medicine industry websites

To collect the semantic core, you need to identify markers — high-frequency key queries that apply to your area of employment.

Answer a couple of simple questions about you and your services:

  1. Who am I/are we?
  2. What services do I/we provide?
  3. What medical field do I work in?
  4. What diseases do I treat?
  5. What do I know about each disease?
  6. Where do I provide my services?
  7. How do I provide my services?
  8. Who am I working for?

The answers to these and other questions will be markers for the future semantic core.

Imagine that you are a dentist. If so, the answers to the questions above might look something like this:

  1. Dentist;
  2. Dentistry, tooth extraction, caries treatment;
  3. Dentistry;
  4. Caries, toothache, holes in the teeth;
  5. How to treat caries, how to remove a tooth, how to treat teeth;
  6. In Florida;
  7. Professional dentist, certified practicing dentist, experienced dentist;
  8. I treat teeth for both children and adults.

Use markers to plan a future or existing website structure. Perhaps the site structure will need to be expanded with additional pages.

To collect the semantic core by markers, you will need such a useful service as SEMrush. If you are the owner of a medical site or a private specialist, analyze the entire list of key requests, and you will see that there is always something to strive for. Do not stop only with commercial inquiries.

Lifehack: “How to find out which articles should I write?”

To do this, use the Keyword Magic Tool section in the SEMrush left panel and enter a search string marker. Next, select the country in which you work. The service will form a large list of key requests. Switch the slider to Questions, and you will see a list of ready-made topics for articles on your website:

Collecting of the semantic core for healthcare industry website

You are a professional in your field and must show your future client that you are an expert in your niche. Only publishing content regularly and expansion of the structure due to the semantic core will help you form the target audience around you, as a medical specialist, or medical institution.


After collecting the semantic core, place additional content on the pages based on an analysis of your TOP competitors. Create a blog branch on the site, a content plan, and begin to conduct stable work on increasing the number of publications.

Do not forget that before becoming your patient, people look for answers to their questions on the Internet. Show that you know about their problem and give a detailed answer in articles.
