You publish texts and other content.
Ensure that the really important things can be easily identified. Construct the headlines and texts in such a way that everything can be scanned and the relevant information can be found quickly by users.
Use clear language
Write in a clear and consistent language. Avoid jargon and idioms. Use clear headlines to structure your content.
Write good alternative texts
Images must have an alternative text and videos must have subtitles. With images, take care that the communicated meaning is described, not the image itself. Don't provide important content just through pictures. Purely decorative images are supported with an empty alternative text.
Make sure that all your links are self-explanatory. For example, several uses of ‘Continue’ should not be used; better to use ‘Continue to login’.
Testing: Hide the text next to the link. Is it still understandable?
