Don't underline words, use italics or write in CAPITALS
Don't use complicated words or figures of speech
Check that the layout is easy to follow:
Avoid large blocks of text:
Large paragraphs of text can be hard to follow. Use left-aligned text with a short line width and don’t justify text, because it can be more difficult to read extra space between words.
Avoid using "Returns" to add space:
Repeated use of the 'return' key to create white space is not recommended. If somebody was using a screen reader, the returns would be read to them as 'click' 'click' 'click'; or 'space' 'space' 'space'; or 'blank' 'blank' 'blank', depending on their settings. If you need to create space in the document, use headers to set your paragraphs apart.
Linking to other pages or resources:
If your content links to a page that you manage which features videos, photos, or audio, include as much descriptive text as possible in your content so users have an idea of what to expect upon arrival. Also make sure that the page to which you are sending users includes content that has descriptive text, captions, or any other description that can help a user understand the page content.
If you do not manage the content on the page to which you are linking and the content is not accessible, inform the user first by including a short note of what to expect. For example:
A video does not have captions or descriptive text
