For years, I avoided anything involving HTML.
My thinking was simple: I’m a writer. Developers handle code.
Then I realized that content writers interact with HTML every day, even when they never open a code editor.
Every time you select H1, H2, H3, bulleted list, numbered list, paragraph, or blockquote in a CMS such as WordPress, you are helping create the underlying structure of a webpage.
You don't need to become a developer. You just need to understand what that structure is supposed to communicate.
What Is Semantic HTML?
Semantic HTML means using HTML elements that describe the meaning and role of content, rather than using formatting purely to make something look a certain way.
For example:
- H1 = the main page heading
- H2 = a major section
- H3 = a subsection within that section
<ul>= an unordered list<ol>= an ordered list<p>= a paragraph<article>= a self-contained piece of content
The important distinction is that visual appearance and structural meaning aren't the same thing.
Making a sentence bold and larger may make it look like a heading. Using a real heading element tells machines that it is a heading.
The H1 → H2 → H3 Structure
One of the easiest improvements writers can make is to treat headings as a content hierarchy rather than a collection of font sizes.
A simple article might look like this:

The goal isn't to obsess over a rigid numbering system. The goal is to make the relationship between sections clear.

Stop Using Bold Text as Fake Headings
This was one of my biggest mistakes.
I'd write a paragraph, make the first sentence bold, increase its size, and assume I'd created a heading.
Visually, it looked fine.
Structurally, it wasn't necessarily a heading at all.
That's an important lesson for content writers: don't use formatting as a substitute for structure.
Use your CMS's actual heading controls when you're introducing a new section.
Lists Are Structural Too
The same principle applies to lists.
Instead of typing:
- First point
- Second point
- Third point
inside a normal paragraph, use the CMS's actual bulleted-list feature.
For numbered processes, use an ordered list.
This gives both readers and machines a clearer representation of the content.
It also makes long articles easier to scan.
Where Schema Markup Fits In
Semantic HTML and structured data aren't the same thing, but they work alongside the broader goal of making content easier for machines to understand.
Schema markup provides additional structured information about a page or entity.

The important point is that schema doesn't replace good content or proper HTML structure. It complements it.
What Writers Actually Need to Know
You don't need to memorize HTML tags.
Start with these habits:
- Use one clear main page heading.
- Use H2s for major sections.
- Use H3s when a section needs subsections.
- Don't choose headings just because their font size looks attractive.
- Use real list formatting for lists.
- Keep paragraphs as paragraphs.
- Use your CMS's built-in formatting tools correctly.
- Review the page structure before publishing.
That's enough to make semantic HTML much less intimidating.
The Bigger Lesson
Learning semantic HTML changed the way I edit content.
I stopped thinking only about how a page looks and started thinking about how the page is structured.
That distinction matters.
Good content needs to work for the person reading it, the systems interpreting it, and the technology helping people access it.
And the best part?
You can get most of the practical benefit without becoming a coder.
