Let your user know where they are going when they select a link. Don’t use ‘Click Here’ or ‘Read More’ for your link text. Learn more about descriptive links.

Images and text are required to meet WCAG 2.1 AA standards. You can check your content with WebAIM’s Contrast Checker(link is external). Avoid light colored text on a light colored background. Learn more about color and color contrast

This makes it easier to navigate a sheet with a screenreader. 

This makes it easier for all users to understand for information and navigate through your file. Avoid sheet names like "Sheet1" or "Unnamed", since these don't provide much content to users. 

Select your table and choose Insert > Table, then select My table has headers.

Keep one table or graphic per sheet and remove any blank sheets to avoid confusion.

Keep your tables as simple as you can.

Avoid blank rows and cells, and avoid merged cells, since these can be difficult for some users to navigate. 

Add additional explination for formulas and data columns.
