How to use H1 tag to maximize SEO effect

We will summarize how to use the H1 tag which exerts the greatest influence on search results, but is not properly used.

What is H1 tag?

I will start with the premise that you do not know about the H1 tag at all.

I am defining it as follows.

The H1 tag is the most important heading tag that explains the entire page


In short, it is a minimum condition that you can explain what this page is about in a sentence.

This page states the following.

  • Concept of H1
  • Relationship between H1 and SEO
  • How many pieces of H1 should I write?
  • What keywords should be included in H1?
  • How many keywords should be included in H1?
  • How many letters should H1 be?
  • Where should H1 be listed?
  • What should we design for H1?
  • Other … …

If you summarize the above in a word, what do you guys do?

I set the H1 tag as follows.


How to use H1 tag to maximize SEO effect

H1 is a large factor of search result ranking

The next thing to consider is about the role that this H1 tag can play in SEO.

The trends and measures of SEO have changed with the growth of search engines.

For example, in the past, it was reflected in the search results simply by flooding the search keyword in the meta tag, but today it does not make any sense at all, it is treated as spam.

We do not need this code anymore.

<meta name="keywords" content="seo,h1,how to use" />

However, the H1 tag is different. If you do not write it will not be reflected in the ranking in search result rankings.

Actually, Google conducts a survey in 2015, about 80% of the sites on the search result page use H1 tags, and even if they spread to 30th place, 79% are using it.

Over 80% of sites on top 10 uses H1
Over 80% of sites on top 10 uses H1

This is a best practice on SEO and is an important and immutable element that Google uses for search result rankings.

First of all, if your site does not use H1 tags, use it now.

How to use H1 tag

I understood that it is important to put H1 tags. Rather than this, there are many people who understand intuitively so far.

However, there are many people who use the wrong way.

To properly use H1 tags, you should be aware of the following points.

One H1 tag per page

H1 tags should be on one page. There is a site that often tags the title of the site with an H1 tag, but it should be on the top page only, and on other pages you should not use the H1 tag.

If you are currently using H1 tags for site titles on all pages, let’s rewrite with reference to the code below.

<?php if ( is_home() || is_front_page() ) : ?>
<h1>Site title</h1>
<?php else : ?>
<div>Site title</div>
<?php endif; ?>

The H1 tag represents the topic of the page

The H1 tag is an important element representing the whole page.

  1. The H1 tag is basically the same as the article title.
  2. For the H1 tag, the reader has to write about the information that will be obtained from now.

H1 tag should be 20-30 characters

The shorter the catch phrase, the more impact you give.


Titles that are too long are not displayed perfectly in search results.

Based on this, the H1 tag should be 20-30 letters.

Include one keyword

This is somewhat controversial. According to the SEO company MOZ

3. Recommending People Use H1 Tags with Keywords
This mistake is a little bit more subtle. For years, SEOmoz recommended including keywords in the H1 of pages. After we started doing formal machine learning correlation tests we found out that this tactic didn’t actually help very much at all (including the keywords in normal text in bigger fonts worked essentially the same). This was a shame because it meant we wasted time and energy convincing our clients to update their H1s.


I do not understand the meaning at all.

As you can see from the above statistics, Google uses H1 tag as one index, it is nonsense not to include the keywords that represent the contents of the page there,

Neil Peter has the same opinion as me and states as follows.

But there’s nothing keyword-stuffing at all about using a keyword in an h1. To the contrary, Google wants you to use a keyword in the h1.
Why? So their crawlers can understand better what the page is all about!
If you don’t use a strong keyword in your h1, then Google can still find out what the page is about, index it appropriately, and give you a nice rank.
But why leave out the opportunity to give Google all of the information it needs and wants right in your website source code?
Use a keyword — a long-tail keyword.


The H1 tag should include keywords. However, you should narrow down the keywords to one, and use long tail keywords.

The experience that user can gain should be included in the H1 tag

Users who visit your site should have a purpose.

For example, suppose a person who wants to receive aesthetic treatment with a dentist.

I want to put white silver teeth in a decayed tooth with white teeth. However, because aesthetic treatment is free practice and expensive, there are few dentistry with abundant experiences of aesthetic treatment. Therefore, choosing a dentist without undergoing pre-emphasis can be hard

Which is the search result that will attract you when this user searches on Google?

  1. Cosmetic dentistry in Tokyo Top 10
  2. Cosmetic dentistry in cities that are cheaply reputed Top 10

On the option of 1, I do not know from the H1 tag about what the ranking is based on.

On the other hand, the option of 2 is based on “cheap · reputation”, so it is easier for users to click.

By the way, this is a story that I myself went to in the past, and as a result it is now indebted to Kamikaido Roppongi Dentistry.

This means that users’ experience is included in the H1 tag.


It is over with what I care about H1 tags. To summarize it will be as follows.

  • H1 tags on one page
  • H1 tags on page topics
  • H1 tags contain 20-30 letters
  • including user experience
