# On the importance of headings

## What is a heading?

A heading is a title or a subtitle displayed in a document or webpage. Headings are created with the <h1> to <h6> HTML tags where <h1> is the main heading and <h6> is the lowest level heading.

## Why use headings

Headings in a document serve a dual purpose: they help the creators and readers interact with the content and affect the way search engines index the webpage.

### Human interaction

Having a clearly defined structure with sections and subsections is beneficial for both the creator and the readers. The creator can convey their message better and emphasize important parts. A few informative headings can help the readers scan the document in search for specific information.

### Search engine indexing algorithms

Search engines use the headings to index the structure of the document and point to important keywords.
