Use a clear document structure
Headings should describe the hierarchy of the page rather than being chosen only for their visual size. A page normally needs one primary heading that identifies its purpose, followed by section headings in a logical order. Semantic HTML gives browsers and assistive technology more information about navigation, forms, articles, and page regions.
Make interactive elements usable with a keyboard
Links, buttons, menus, form controls, and dialogs should be reachable without a mouse. Visible focus styles help users see which control is active. Custom controls need appropriate keyboard behavior instead of responding only to pointer clicks. Test important workflows by using Tab, Shift+Tab, Enter, Space, and Escape.
Label forms and explain errors
Every input should have an understandable label or equivalent accessible name. Placeholder text is not a replacement for a label because it disappears when typing and often has poor contrast. When validation fails, explain what needs to be corrected and keep the message close to the relevant field. Avoid clearing the entire form after one mistake.
Use alternative text intentionally
Informative images need alt text that communicates their purpose. Decorative images can use an empty alt attribute so they do not create unnecessary noise. Do not stuff keywords into alt text. For icons used as buttons, the control itself should have a readable label even if the icon is visually obvious.
Check contrast, motion, and mobile layout
Text and controls should remain readable against their backgrounds. Respect reduced-motion preferences for users who are sensitive to animation. Zoom the page and test narrow screens to make sure content does not overlap or become unreachable. Accessibility improvements often improve usability for everyone, including people using small screens, temporary injuries, or slow connections.
Next step
Apply the parts that fit your website, then measure the result. Sustainable website growth comes from useful pages, accurate information, relevant promotion, and consistent improvement rather than guaranteed ranking shortcuts.
