What is an H1 tag and why does it matter for SEO?

A good web article needs more than good content. Its form and its heading structure (H1, H2, H3 and so on) matter too. They let readers scan and grasp the main points easily, and a well-structured article is rated better by Google and climbs the keyword rankings faster. So, what is the H1 tag? And how do you optimize the H1 tag for SEO? The article below from MONA Media will help you answer these questions.

What is the H1 tag?

H1 tag is the first heading displayed on the content of a page. Usually readers only see this tag after they click into the article.

The Heading 1 tag is formatted completely differently from other Sub Heading heading tags such as H2, H3 and H4. It is short, covers the whole article and sits at the very top.

Although it is a small element, the H1 tag in HTML still helps your website grow in Google search. To learn more about what H1 tags mean and the role they play in SEO please keep reading.

Why the H1 tag matters in SEO

When you write an article, the heading tags, H1 first, form its outline and structure. That lets readers grasp the whole article quickly, and the Heading 1 tag helps them find the information they want fast. If the article matches what the visitor was looking for, they stay on your site longer, which helps Google rank your content higher.

For Google, the H1 and H2 tags help it picture what the article is about. From the H1 and H2 titles, Google can tell whether the content matches the user's query. If it does, Google keeps reading the article for the information contained in the headings through the HTML markup.

So the Heading 1 tag in HTML not only helps Google judge the article's content well, it also gives users a much better experience.

How does the H1 tag differ from the title?

Many people think the title and the H1 tag are the same thing, but they are not. Here is how to tell the two apart:

• Heading 1 only appears when a user clicks through to an article. The Heading 1 tag does not appear in Google's search results.
• The SEO title is the title of the whole page, so it is shown in search results. Put simply, it is the title users see when they search on Google, and it does not appear inside the article.

Can the H1 tag and the title be the same?

A question that people new to SEO often ask is: Can the H1 tag and the title have the same text?

As explained above, the H1 tag and the title are two different elements. They differ in how and where they show up in SEO, but their text can be the same or different.

Whether the <h1> tag and the title match or not, both need to follow SEO best practices to perform well in Google search.

How to optimize the H1 tag for SEO

Google usually reads an article through its headings. So for Google to read your article faster, you need to optimize the heading tags headings, especially the H1 tag. Here are ways to optimize the <h1> tag in standard HTML SEO Onpage

1. One H1 tag per article

If an article has too many heading tags with the same content, it affects how Google evaluates it. The H1 should appear only once, since that is the standard structure. Several identical H1 titles can also annoy readers because the content repeats.

2. Don't repeat the H1 tag across articles

Repeating the Heading 1 tag across articles is not necessarily a disaster, but it can leave Google confused about which keyword each article targets.

3. The H1 tag must reflect what the user is searching for

The Heading 1 does not need to be long, but it should cover the article and state its main point. Above all, it must contain information that answers the user's query.

The H1 tag matters because it sits at the top of the page and is the first thing users see when they click through. If it doesn't give them the information they want, they will probably leave. The site then loses potential customers, and its SEO results suffer too.

4. The H1 tag must contain the keyword

When writing, work the keyword into the H1 tag. That makes it easier for Google to understand and judge the topic of your article, and it helps your SEO work better.

Don't overdo it, though. Stuffing too many keywords into the H1 heading counts as keyword spam, and users will struggle to see what the article is about.

5. Keep the H1 tag under 70 characters

Keep the H1 tag short and complete, not long, at around 65 to 70 characters. If it runs long, Google reads it as a sentence and your SEO results suffer. You can also judge by eye whether your H1 tag looks right.

Specifically, check the following when optimizing the h1 heading:

• Is the H1 tag interesting enough to attract users?
• Is the Heading 1 too long?
• Does the H1 tag already contain the keyword?
• Does it answer the searcher's query?

• The H1 tag should not be too long, at around 70 characters.

Many people do SEO without knowing the standard rules for H1 tags and titles, so they often make mistakes like these: the Heading 1 is too long, has no keyword, or duplicates another article. So how do you check for these errors quickly?

You can use the search syntax allintitle:Your title to check whether your title duplicates the titles of other articles. You can also use Screaming Frog to check H1 tag and title errors in more detail.

How to fix H1 and title errors

Once you find the cause of an H1 or title error, you can fix it. The best solution depends on the error.

If the H1 tag is too long, shorten it so that it still holds the main keyword plus a semantically related (LSI) keyword. If it is too short (say, only 2 words), add suitable words so it describes the content properly.

If an article has no H1 tag, add one. Without it, optimization suffers and users may not find your article. Make sure the H1 and the title are within SEO length limits and give users genuinely useful information.
