# Headings: HTML section titles

Reviewed on 2026-10-07.

## What it means

Headings are section titles represented by the [HTML](/en/resources/glossary/html-the-web-s-markup-language) elements h1 to h6. These levels describe the content hierarchy: h1 is the highest level and h6 the lowest. This markup helps identify chapters and subsections on a page. CSS can set the text’s visual size without changing its semantic level.

## Why it matters for marketing

For marketing and content teams, a clear hierarchy makes the material’s organization easy to verify before publication. It helps distinguish the main topic, the questions answered, and the details in each section. It also supports navigation with screen readers. Choosing headings only to make a sentence larger can create a structure that differs from what the text is meant to communicate.

## Example in practice

Imagine an agency reviewing a page of plans. The main title is marked as a paragraph, while each price gets an h1 because it is prominent. By inspecting the sequence of headings, the team identifies this reversal. It requests an h1 for the page topic and appropriate levels for the plans, while preserving the prices’ visual prominence through presentation styles.

## How to apply or check

Check the elements actually rendered and the list of headings available in the browser or an accessibility tool. Verify that the page has a clear main topic and that subsections follow the level sequence. Prefer an h1 that describes the page and avoid skipping levels without a reason. The CMS needs to allow appropriate markup as well as visual formatting.

## Important distinctions

A heading is not the same as a title, the element that provides the document title, or an HTTP header. Large or bold text does not automatically become a section title. An organized sequence also does not prove content clarity or a ranking advantage. Review the meaning of the titles, their levels, and the information they present.
