So, what is semantic markup?

Semantic markup is the practice of using HTML elements to describe the meaning and structure of content on a web page. This means assigning appropriate tags—such as headings (<h1>, <h2>), lists (<ul>, <ol>), and emphasis (<strong>, <em>)—to convey the purpose of each piece of content. By doing so, you ensure that your website is not only visually organized but also logically structured for both users and search engines.

In this article, I’ll explain why semantic text markup is critical for creating a user-friendly, accessible, and professional website. I’ll also provide examples of how to structure content effectively, including tips to avoid common mistakes.

1. Enhancing Text Readability

When website content is well-structured, users can easily navigate and find the information they need. This is especially important if you want your content to stand out.

Headings

Headings help divide text into logical sections. For example, the main page heading should always be H1, with subsections using H2, H3, and so on.

Example of correct heading markup:

<h1>Why Proper Text Markup Matters</h1>
<h2>1. Enhancing Text Readability</h2>
<h3>Headings</h3>
<p>Headings help structure text and make it easier to read.</p>

Common mistake: using H3 instead of H1, or multiple H1s on the same page. This confuses both users and search engines.

Example of incorrect heading markup:

<h3>Why Proper Text Markup Matters</h3>
<h1>1. Enhancing Text Readability</h1>
<h1>Headings</h1>
<p>Headings help structure text and make it easier to read.</p>

‍

Lists

Lists make information easier to understand, especially when outlining steps or creating summaries.

Example of correct list usage:

<ul>
    <li>Use numbered lists for ordered steps.</li>
    <li>Use bullet points for unordered items.</li>
</ul>

‍Example of a mistake: using <br> tags instead of <ul>:

<p>
    ・Step 1<br>
    ・Step 2<br>
    ・Step 3
</p>

2. Optimizing for Search Engines

SEO is directly impacted by proper text markup. If your content structure is clear, search engines can better understand what your page is about.

Headings

Headings and their levels help search engines understand what your text is about and rank it for keywords. Incorrect use of headings can make it difficult for a page to be indexed, which will lead to a decrease in its position in search engines.

‍

Example: The main heading of the article (H1) should be unique and contain the main keyword. Subheadings H2 and H3 support the general topic and help search engines better understand the structure of the text.

Keywords

1. Improved Readability and Scannability
   People often skim text rather than reading it word for word. Headings and lists act as visual anchors, making it easy for readers to quickly find the information they need. Placing keywords in these elements ensures that the most critical terms stand out, drawing attention to the key ideas.
2. Enhanced SEO
   Search engines prioritize structured content. Keywords in headings signal the relevance of sections to specific queries, helping your content rank higher in search results. Similarly, including keywords in lists emphasizes their importance to search engines, which recognize list elements as a means of highlighting key points.
3. Logical Flow and Context
   When keywords are integrated into headings and lists, they provide context and structure. This reinforces the theme of your content and ensures that every part of your document contributes to its overall message.

Example:

<h2>Optimizing Text for SEO</h2>
<ul>
    <li>Include keywords in headings.</li>
    <li>Use them sparingly in the body text.</li>
</ul>

‍

3. Accessibility for Users with Disabilities

This is an important topic often overlooked. Proper text markup ensures that users relying on screen readers can navigate your site effectively.

Example of accessible markup:

<h1>Main topic</h1>
<h2>Key sections</h2>
<ul>
    <li>Point 1</li>
    <li>Point 2</li>
</ul>

Incorrect markup can lead to screen readers presenting content in a chaotic order, confusing users.

4. Maintaining a Professional Image

We’ve seen many cases where clients are surprised that an improperly formatted website can deter users. In reality, well-structured and carefully formatted content demonstrates professionalism and builds trust in your brand.

No-code Makes it Easer

Creating and maintaining proper semantic markup doesn’t have to involve complex coding. No-code tools like Webflow simplify the process, allowing you to focus on structure and design rather than technical details. With its intuitive drag-and-drop interface and built-in semantic elements, Webflow empowers anyone—from designers to business owners—to create professional, well-structured websites.

Webflow includes a wide array of pre-configured elements designed to ensure proper semantic markup right out of the box:

‍

Of course, these are not all the available elements, but the main ones, touched upon in the article. In addition to semantic markup of text, it is also desirable to mark logical blocks on the website. For example: <header>, <footer>, <nav>, <main>, <section>, etc.

Conclusion

Proper semantic text markup is a fundamental aspect of creating a user-friendly, accessible, and effective website. If you want your site to attract clients, rank well in search engines, and meet modern standards, focus on the details of your markup. Check how your headings, lists, and accents are formatted.
