If you are into blogging, SEO, or content writing, you must have heard about H1, H2, H3 headings. These headings are not just for making the text big or small — they actually play a major role in Google ranking, readability, user experience, and helping search engines understand your content.
Most beginners get confused because they jump into blogging after watching social media videos about “earning money from websites,” but they start without proper knowledge. As a result, they struggle — they don’t understand SEO, they don’t know how to structure content, and they don’t know how to properly use heading tags.
But don’t worry!
This guide is written in simple, clear English based on practical experience. By the end of this article, you will fully understand H1 to H6 headings — and you will be able to use them like a pro in your blog posts.
In this complete guide, you will learn:
- What is H1?
- What is H2?
- What is the purpose of H3?
- How to use H4, H5, and H6?
What Are Heading Tags (H1 to H6)? — Simple Definition
Heading tags are a part of HTML that help Google and readers understand the structure of your content.
Think of it like a book:
- H1 = Book Title
- H2 = Chapter Names
- H3 = Topics inside the chapter
And H4, H5, H6 are deeper subtopics used when needed.
Example (HTML):
<h1>Book Title</h1>
<h2>Chapter 1</h2>
<h3>Topic 1.1</h3>
<h3>Topic 1.2</h3>
<h2>Chapter 2</h2>
Exactly like this, your blog post follows a hierarchy using H1 to H6.
What Is H1?
H1 is the main heading of your page.
It tells Google and users what your page is about.
Rules:
- Only one H1 per page (best practice)
- Must include the main keyword naturally
- Should be clear, short, and specific
Good Example:
<h1>Heading H1, H2, H3… H6: Complete Guide for Blogging & SEO</h1>
Mistakes to Avoid:
- Using multiple H1 headings
- Keyword stuffing
- Very long or confusing H1
What Is H2?
H2 headings are your main sections.
They divide the article into major parts.
Examples of H2 in this article:
- What is H1?
- What is H2?
- Importance of headings in SEO
- Best example of heading structure
H2 headings help Google understand the major topics of your blog post.
What Is H3?
H3 is used inside an H2 section.
Example:
H2 → “Importance of heading tags in SEO”
H3 → “Better user experience”
H3 → “Improved crawling & indexing”
H3 → “Higher chances of featured snippets”
Use H3 only when you have sub-topics under an H2.
H4, H5, H6 — Do You Really Need Them?
These are optional and used only when your content is very deep.
Example:
- H4 = Sub-topic inside H3
- H5 = Even more detailed sub-topic
- H6 = Rarely used
Most blog posts use only H1, H2, H3.
Why Are Heading Tags Important for SEO?
- 1. Help Google Understand Your Content
Search engines read headings to understand your page structure and main topics.
- 2. Improve User Experience
Readers can quickly scan and find the information they need.
- 3. Better Crawling & Indexing
Clear structure helps Google crawl your page more efficiently.
- 4. Increase Chances of Getting Featured Snippets
Google often pulls concise answers from well-structured H2 or H3 headings.
- 5. Improve Accessibility
Screen readers use headings to help visually-impaired users navigate content.
Perfect Heading Structure Example
Let’s take a topic: “How to Take Care of Clothes”
Here’s a perfect structure:
<h1>How to Take Care of Clothes: Complete Guide</h1>
<h2>1. Washing Tips</h2>
<h3>• How to separate clothes</h3>
<h3>• Machine wash vs hand wash</h3>
<h2>2. Drying Methods</h2>
<h3>• Sunlight vs shade</h3>
<h4>– Tips for delicate fabrics</h4>
<h2>3. Ironing and Storage</h2>
This makes your article:
- Easy to read
- Easy for Google to understand
- Easy to rank

Content Length vs Heading Usage
| Content Length | Best Heading Pattern |
|---|---|
| 300–700 words | 1–2 H2 + few H3 |

| 1500+ words | TOC + structured H2/H3 |
For long SEO articles, heading structure matters the most.
