What Is an H1 Tag? Definition, Examples & Best Practices

Key takeaways:

Use one H1 per page
Include your target keyword naturally

An H1 tag is the main heading of a webpage. It tells both readers and search engines what the page is about.

Here’s what the H1 tag can look like on a web page:

And here’s how it looks in the form of an HTML code:

Why does the H1 tag matter? How do you add one to your page? And what are the best practices to follow?

Let’s break it all down in this guide.

What Is an H1 Tag?

An H1 tag is an HTML element that defines the main subject of a webpage. It is the most important heading on the page.

Here’s what it looks like in HTML:

H1 tags help Google understand what your page is about.

Every page can have multiple heading levels: H1, H2, H3, all the way to H6. They work like an outline:

H1 = Main title (what the whole page is about)
H2 = Major sections
H3 = Subsections under H2s
H4 to H6 = Deeper sublevels (you’ll rarely need these)

Why H1 Tags Matter for SEO?

Google uses your H1 to understand your page

Google’s John Mueller has confirmed that H1 tags help Google understand page structure.

A clear H1 makes Google’s job easier, which improves your chances of ranking for the right keyword.

Example: A page with the H1 “Beginner’s Guide to Email Marketing” clearly tells Google what the page is about. But a vague H1 like “Welcome to Our Blog” tells Google nothing.

Improves User Experience

Your H1 is usually the first thing people see after they land on your page.

If there’s no H1 or it’s confusing, visitors may feel they’re on the wrong page and leave quickly. That hurts your search rankings.

It Gives your Page Structure

The H1 is the foundation of your page’s heading hierarchy. It works together with H2s and H3s to create a structure readers can skim and understand.

Here’s what a simple heading hierarchy can look like:

H1 Tag Examples (Real Page Examples)

Here are real-world examples of H1 tags used across different page types.

Blog Post H1:

Moz uses H1 tags that clearly explain what a post covers and who it’s for.

Example: “Informational Keywords: What They Are and How to Use Them.”

Works because it clearly describes the page topic and matches what users expect to learn from the content.

Ecommerce Product Page H1:

The H1 tag on a Runner’s World guide about running shoes is “The 10 Best Running Shoes for Men.”

It’s clear, specific, and perfectly tells the shopper exactly what they’ll find.

Landing Page H1:

The H1 tag on a HubSpot guide on email list building is “49 simple ways to grow your email list.”

It is benefit-driven and action-oriented. Works well for landing pages where the goal is conversion, not ranking for a definition keyword.

Bad H1 Example:

“Welcome to Our Website”

It tells Google nothing. Gives readers no reason to stay.

H1 Tag vs. Title Tag

These two get mixed up all the time. Here’s the difference:

	H1 Tag	Title Tag
Where it appears	On the webpage itself	In Google search results & browser tabs
What it does	Main page heading for readers	SEO page title for search engines
Purpose	Explains the page topic	Drives clicks from search results
Visible to visitors?	Yes	Only in the browser tab

How Many H1 Tags Should a Page Have?

One. Always one.

Using multiple H1 tags confuses search engines about what the page is actually about.

One H1, but you can use multiple H2s and H3s.

Note: Google’s John Mueller has said multiple H1s won’t break your site. But it’s still not best practice, so stick to one.

H1 Tag Best Practices for SEO

Follow these simple H1 tag best practices to make your content more helpful for readers and easier for search engines to understand.

1. Use Only One H1 Tag

Covered above, but worth repeating. One page, one H1, one main topic.

2. Include Your Primary Keyword

Your H1 should include the keyword you’re trying to rank for, naturally.

If your target keyword is “email marketing for beginners,” a good H1 would be:

“Email Marketing for Beginners: How to Get Started in 2026”

You don’t need an exact match. You can add a keyword that’s relevant to your topic.

3. Keep It Clear and Descriptive

Your H1 should tell readers exactly what they’ll get from the page.

Vague: “Everything You Ever Wanted to Know”
Clear: “How to Start a Blog: Step-by-Step Guide for Beginners”

4. Match Search Intent

Look at the top-ranking pages for your keyword. How are they crafting their headlines? What tone and format are they using?

For the topic “How to learn SEO,” the top results are beginner-friendly how-to posts. That means your H1 should also be a simple tutorial, not a sales pitch.

5. Keep It Under ~70 Characters

Most CMS platforms use your H1 as the title tag. Google cuts off titles above 60-70 characters in search results.

The ideal length: 50-60 characters

If your H1 is too long, Google will truncate it, and that hurts your CTR.

How to Add an H1 Tag in WordPress, Wix & Squarespace?

Learn how to easily add an H1 tag in WordPress, Wix, and Squarespace with these simple steps.

WordPress

Your post title in WordPress is automatically the H1. You don’t need to touch anything.

To set a heading as H1 inside your content manually:

Open the post editor
Click on a Heading block
In the block toolbar, click the heading level dropdown
Select H1
Type your heading and publish

Wix

Wix automatically uses your blog post title as the H1 tag. Unlike WordPress, you can’t assign the H1 to other text, as it’s fixed to the post title.

Squarespace

Just like on Wix, your blog post title in Squarespace is automatically set as the H1.

To change a heading on a page manually:

Click the text block you want to change
Select the text
Click the formatting button in the toolbar
Choose Heading 1

Raw HTML

If you’re coding directly in HTML:

<h1>Your Page Title Goes Here</h1>

Place it once, near the top of your <body> section.

How to Check H1 Tags on Your Website?

There are three quick ways:

#1. View Page Source

Right-click anywhere on the page, select “View Page Source,” press Ctrl+F (Cmd+F on Mac), and search for <h1>.

#2. Inspect Element

Right-click directly on the heading, select “Inspect,” and look for text wrapped in <h1> tags.

#3. Browser extension

Install the free Ahrefs SEO Toolbar or Detailed SEO Extension. Both show all heading tags on any page instantly.

H1 Tag Optimization Checklist

Before you publish any page, check this:

You use only one H1 on the page
The H1 includes your primary keyword naturally (or a closely related keyword)
It stays under 70 characters (ideally 50–60)
It matches the search intent of your target keyword
It clearly describes the page content
It’s unique and not copied from another page on your site

Frequently Asked Questions on H1 SEO

Here are some frequently asked questions about H1 tags.

What is the purpose of an H1 header tag?

The H1 tag tells search engines and users the page’s main topic. It is also the highest-level heading tag, as heading tags range from h1 to h6.

Can a page have multiple H1 tags?

Yes, technically. Google won’t penalize you. But it’s not recommended because multiple H1s can confuse search engines about the page’s main topic. So it’s best to use only one H1.

Should the H1 match the title tag?

They don’t have to be an exact match, but they should be highly relevant. A completely different keyword in the H1 and title tag confuses both users and search engines.

Does the H1 tag directly affect Google rankings?

It’s not a direct ranking factor. But it helps Google understand your page topic and improves user experience.

Should every page have an H1?

Yes. Every page you want to rank should have a clear H1. Pages without an H1 tag are harder for Google to understand.

Should I include my target keyword in my H1 tag?

Yes, you should DEFINITELY include your target keyword in your H1 tag, as it will help search engines understand your page’s content.

What are some common H1 tag mistakes?

Here are some common H1 tag mistakes to avoid in 2026;
– Using multiple H1 tags within one page (or blog post)
– Not using any H1 tags on a page
– Using H1 tags that are NOT relevant to the content of the page
– Using lengthy H1 tags

How long should an H1 tag be?

Aim for 50 to 60 characters if possible.

What if my H1 and title tag are different in WordPress?

Use an SEO plugin like RankMath or Yoast SEO. Both plugins let you write a custom title tag that’s separate from your H1.
