Should icons be before or after text?

Icons visually communicate the button's action and help draw attention. They should be placed on the leading side of the button, before the label text.

Why do we use the label icon?

Icons Need a Text Label

To help overcome the ambiguity that almost all icons face, a text label must be present alongside an icon to clarify its meaning in that particular context.

How are icons used?

Why are icons used? As graphic symbols, computer icons help users quickly and easily identify what they need or want. The use of icons also provides a more appealing visual representation, which makes them more enjoyable to use than traditional text-based links.
