- Very small text.
- Very low contrast between the text and background.
- Empty alternative text: images don’t have an alternative text which is necessary in case the image doesn’t load in some devices
- Redundant title, the title should be different from the alternative text which is more descriptive of what is going on with the text or image.
- Broken ARIA menus
- Empty buttons
- Redundant links
- Redundant title text
- Skipped heading level; titles don’t follow a hierarchal order e.g. h1 title shouldn’t be followed by a h3 title so it should be h1 followed by h2 then h3.
