When writing a blog post or designing a landing page in WordPress, it is incredibly tempting to use heading tags (H1, H2, H3) simply to change the size or boldness of your text.
“This H3 looks too big, let me use an H5 instead.”
If you have ever done this, you have accidentally broken your page’s heading hierarchy. While it might look visually pleasing to human eyes, you have just created a confusing, broken roadmap for search engine crawlers.
In this guide, we will explain why a strict H1–H6 hierarchy is crucial for SEO, what “skipped levels” are, and how to fix your content structure to rank higher.
Why Heading Hierarchy Matters for SEO
Search engines like Google rely on heading tags to understand the context, relevance, and structure of your page. Think of your webpage as a textbook.
- The H1 is the title of the book.
- The H2s are the chapters.
- The H3s are the sub-sections within those chapters.
When Googlebot crawls your page, it reads this outline to figure out exactly what your content is about. Furthermore, heading hierarchy is a massive factor for Web Accessibility (WCAG). Visually impaired users rely on screen readers that use heading tags to navigate through your content. If your structure is broken, their experience is ruined—and Google heavily penalizes sites with poor accessibility.
The Problem: What Are “Skipped Levels”?
A “skipped level” occurs when you jump down the heading hierarchy by missing a sequential step.
An example of a BROKEN (Skipped) Hierarchy:
<H1>The Ultimate Guide to Coffee</H1><H2>How to Brew Espresso</H2><H4>Choosing the Right Beans</H4>(Wait, where is the H3?)
In the example above, the writer skipped the H3 tag and jumped straight to an H4. To a search engine crawler, this is a missing link. It breaks the logical flow of information, making it harder for Google’s algorithm to confidently understand the relationship between “Brewing Espresso” and “Choosing Beans.”
The Golden Rules of Heading Tags
To maintain a perfect, SEO-friendly structure, follow these rules:
- Exactly ONE H1 per page: This should be your main title and contain your primary keyword.
- Use H2s for main points: Break your content down into major sections using H2 tags.
- Nest logically without skipping: If you need to break down an H2 further, use an H3. If you need to break down that H3, use an H4. Never skip a number going down. (Note: It is perfectly fine to jump back up, for example, moving from an H4 back to a new H2 to start a new chapter).
- Do not use headings for styling: If you want a piece of text to be smaller, bold, or colorful, use CSS or WordPress block styling options. Never use an H5 just because you like the font size.
