Check for properly defined headings within any websiteScreenshot of Sitebeam's page headings test

Why is it important?

Using headings well has a positive effect on search engine rankings.

They also help accessibility (users with screen readers often browse a page by headings, to save listening to entire pages being read out).

Using headings also helps the usability of a website, making it easier for users to scan the text.

How is it measured?

A heading is a specially defined block of text visible within a web page – technically, it is text inside a Heading tag (<h1>, <h2>, <h3> and so on). Sitebeam checks that at least one of these is used on each page.

Sitebeam also checks whether the contents of these headings is appropriate (e.g. that they contain some actual text), and that they are nested appropriately.

The score is taken from the proportion of pages with properly defined headings, weighted for the relative importance of the pages they appear on. The best possible score would come from using headings on every page.
