Understanding HTML Headings

Introduction

HTML Headings are a crucial part of any web page's structure. They provide the page's content with a hierarchy of importance, making it easier for users and search engines to understand the main topics and sub-topics covered on the webpage. Headings also help visually impaired users improve accessibility to navigate the content using screen readers.

In this article, we will cover all the important information you need about HTML headings, including how to use headings properly and how headings can help with SEO optimization.

What are HTML Headings?

In order to organize the content of a web page, HTML headings are used. HTML headings are used to structure the content present on a web page. Headings are used in organizing the entire web page text into different sections with different levels of importance. There are six different levels of HTML headings ranging from H1 to H6. The heading inside H1 is considered the most important, and the heading inside H6 is considered the least important.

Each heading level - H1, H2, H3, H4, H5, and H6 has a different font size and font weight for the text written as the heading, where H1 is the largest and boldest and H6 is the smallest and lightest in size and weight of the text. Headings are generally used hierarchically, starting from H1 for the web page's primary title and then H2, H3, and others being used for subheadings and other important sections of the content.

What is the Importance of HTML Headings?

Several factors make HTML headings important. First and foremost, they help to organize the content of a web page clearly and logically. This increases the readability of the web page and helps the users traverse through the web page so that they can find the relevant data they are in search of quickly and efficiently.

Secondly, HTML headings are also important and active in SEO optimization. The headings on a web page help search engines like Google understand the main topics and subtopics covered in the content. Proper use of headings in the web page while designing the content helps the search engines to understand the structure of the content and helps to improve the rankings in the search results.

How to effectively use HTML Headings?

Proper use of HTML headings is essential for both usability and SEO optimization. The HTML headings should always be utilized correctly like,

Use the H1 heading tag level for the main title of the web page. The page's main title should always be included in an H1 tag. The heading inside the H1 tag should be the most important heading on the page and should appropriately describe the page's content.
Use the H2 heading tag level for subheadings to divide the page's content into several parts. Each section should have a descriptive subheading that can appropriately describe the content of that section particularly.
Use the H3-H6 heading tag level for the subheadings inside sections. If there are subheadings inside a section, using H3-H6 headings to indicate the significance of each subsection is appropriate.

Implementing HTML Headings using Code

HTML headings play an important role in defining web page structure and help optimize SEO to improve rankings in Google searches. Headings are also beneficial for visually impaired people to help them navigate through the content using screen readers. But implementing headings to perform such tasks in our web pages uses HTML coding, which follows a certain syntax.

In HTML, there are six headings ranging from H1 to H6; all these heading tags are implemented in our HTML document just by including the appropriate heading tags around the text we want as a heading.

Like. <heading tag> Text that we want as heading</heading tag>

Tags used as heading levels are - <h1> , <h2>, <h3>, <h4>, <h5> and <h6>

Heading tag used	Heading tag level
<h1>.....</h1>	Level 1
<h2>.....</h2>	Level 2
<h3>.....</h3>	Level 3
<h4>.....</h4>	Level 4
<h5>.....</h5>	Level 5
<h6>.....</h6>	Level 6

Syntax

<h1> This is Heading Level 1</h1>

Implementing Headings on a Webpage: Best Practices

Use heading to structure the web page content hierarchically, with the level 1 heading being the most important and moving down to the level 6 heading being the least important.
Headings should be descriptive; each heading should appropriately provide adequate information about the content of that particular section.
Only one Level 1 heading should be used inside per webpage to reduce confusion to search optimization engines and improve the content's readability.
Using keywords in headings can help improve search result rankings during SEO optimizations.
It is a good practice to avoid using too many headings on a web page; this sometimes confuses the user and the search engines and makes the content difficult to read.
Heading used just for formatting in a web page to increase the font size is not advised, rather than use headings to mark a particular section and to increase the readability of the content using the points mentioned above.
