TL;DR: HTML headings (H1 to H6) that organise a page so users and search engines can follow it.
In a nutshell
Header tags create a logical hierarchy on your page, like chapters in a book. The H1 is the main title, H2s are major sections, H3s are subpoints. For example, a blog about meta titles uses one H1, H2s for each topic, and H3s for tips. Used correctly, they help rankings, accessibility and featured snippets.
Quick answer: Header tags (H1, H2, H3, H4, H5, H6) are HTML tags that define a page’s heading hierarchy. They tell users and search engines about the structure and topic of a page’s content. Used correctly, they make pages scannable for readers and parseable for search engines and AI assistants. Misused, they confuse both.
What Are Header Tags?
Header tags, H1, H2, H3, and so on, are the structure behind your page’s content. They create a hierarchy of headings and subheadings that help users (and search engines) understand the layout and logic of your page.
Think of them like chapters in a book. The H1 is the main title. The H2s are your chapters. The H3s are your subheadings within each chapter, and so on.
In HTML, it looks like this:
<h1>What Are Header Tags?</h1>
<h2>Why They Matter for SEO</h2>
<h3>Best Practices</h3>They’re simple. But when used properly, header tags improve accessibility, readability, and SEO all in one go.
Why Header Tags Matter for SEO
Google loves well-structured content. When your page has clear, logical sections with relevant headings, Google can better understand:
- What your content is about
- Which topics are related or grouped
- What the most important sections are
That makes it easier to rank, and easier to win featured snippets or sitelinks, too.
At BrisTechTonic, we include header structure checks in every SEO Audit and technical SEO plan. Because messy headings = messy rankings.
What’s the Difference Between H1, H2, H3, etc.?
Header tags follow a strict hierarchy:
- H1: Used once per page. This is your main headline (e.g., the title of a blog post or product page).
- H2: Main sections of your content. Think of these as topic chapters.
- H3: Sub-points or subsections within your H2s.
- H4–H6: Used for deeper nesting if needed, but rarely required on most pages.
Important: Don’t skip levels. Don’t jump from H1 straight to H4. That’s like building a staircase with missing steps, bad for users and bots alike.
Header Tag Best Practices
Here’s our BrisTechTonic-approved checklist:
- Only one H1 per page, it should reflect your page’s main topic or target keyword.
- Use H2s for major sections, break content into logical chunks.
- Include target and semantic keywords, naturally, don’t stuff.
- Don’t use headers just for styling, use CSS for visual changes, not structure.
- Make them human-readable, avoid robotic, keyword-stuffed gibberish.
How Header Tags Help SEO (Real Examples)
Let’s say you’re writing a page about meta titles. Your structure might look like this:
<h1>How to Write Meta Titles That Boost SEO</h1>
<h2>What Is a Meta Title?</h2>
<h2>Best Practices for Writing Titles</h2>
<h3>Include Your Focus Keyword</h3>
<h3>Use a Number or Power Word</h3>
<h2>Common Mistakes to Avoid</h2>This hierarchy makes your content scannable, helps Google understand subtopics, and gives you a chance to show up in featured snippets like “How to…” lists and FAQs.
Where to Set Header Tags in WordPress (Bricks Builder too!)
Most page builders, including Bricks Builder (our go-to), let you define the tag level (H1–H6) for each text block. Always double-check that what looks like a heading is semantically correct.
Just because it’s bold and big doesn’t make it an H2! Check the settings or inspect the HTML to be sure.
Header Tags and Accessibility
Screen readers use headers to help users navigate your content. A clear structure means better accessibility, and better inclusivity. Google cares about that too.
It’s one of the reasons we pay close attention to heading structure during website migrations. A quick remap of headings can improve both SEO and usability overnight.
Header Tags and Featured Snippets
Want to win a “How to…” or “List” snippet? Use headers like:
- H2: How to Optimise Header Tags
- Followed by H3 steps or bullet points
Google often pulls these directly into SERPs, especially when content is well-structured and concise under each subheading.
Common Mistakes We See (And Fix)
During audits, we often find:
- Multiple H1s (bad for clarity)
- Missing H2s (no structure)
- Header tags used for styling only (e.g., H4s in the footer)
- Long, vague headings that mean nothing to Google
Our fix? A quick restructuring session as part of our SEO Strategy workshop or Blueprint course.

Frequently Asked Questions
Should I have one H1 per page?
Yes, almost always. The H1 is the page’s primary title, and Google treats it as the strongest topical signal in the heading hierarchy. HTML5 technically allows multiple H1s, but for SEO clarity and accessibility, one H1 per page is the safer default.
Can I skip heading levels?
You can, but you should not. Going from H2 to H4 (skipping H3) is valid HTML but breaks the logical hierarchy. Screen readers and SEO crawlers both expect heading levels to descend in order. Fix it by using H3 instead of H4 where appropriate.
Do header tags affect SEO rankings?
Indirectly, yes. Google uses headings to understand page topic and structure. Pages with clear, topic-aligned headings give Google better signals than wall-of-text pages. The effect is meaningful but not dominant; topical content depth and link signals matter more.
Should I put my keyword in every heading?
No. Force-fitting keywords into every heading sounds robotic and may even hurt rankings. Use the focus keyword in the H1 and one or two H2s where natural. Other headings should describe their section in plain language.
