As most people scan Web pages, and also to assist those with reading difficulties and those using assistive technology, it is very important that the information contained in a document is presented correctly. The correct use of bullet points, headings and summary paragraphs throughout a publication will ensure that the maximum number of readers will gain the information you wish to impart.

Every page should be written as if the user has not seen the rest of the site. Many visitors will access Web pages direct from internet search engines, or through links from other web sites.

However, the first two levels should not replace whole documents, such as in depth articles, no matter how long they might be.
To achieve scannable text, web pages should employ:
