A button, also known as a call-to-action (CTA), is a clickable control that initiates an action or changes a condition. Buttons allow users to take action.

Best practices for writing button copy


For readability, limit buttons to 1 or 2 words, maximum 3.

When pairing a button with a single-action instruction, match the button's wording to the title. This parallelism adds clarity. For example:

  • Title: Download package?
  • Button: Download package

Word choice

Lead with strong verbs that invite a specific action. For example, “Download <file>” or “Import <file>.”

For example, “Download package” is clearer than “Download.”

Use simple, common, specific phrases that are familiar to the user.

Avoid unnecessary words and articles such as “the,” “an,” or “a.”
