Introduction
Well-structured content is easier for both people and search engines to understand.
One of the simplest ways to improve your content structure is by using heading tags correctly.
Headings help organise information into logical sections, improve readability, and provide search engines with valuable context about your content.
In this guide, you'll learn what heading tags are, how they work, and how to use H1, H2, and H3 headings effectively.
Quick Answer
Heading tags are HTML elements used to organise the structure of a webpage.
They range from H1 to H6, with H1 representing the main topic of the page and H2–H6 creating a clear hierarchy of supporting sections.
Why Heading Tags Matter
Heading tags help:
Improve readability
Organise content logically
Help search engines understand page structure
Make long articles easier to scan

A well-structured page creates a better experience for both users and search engines.
