Site icon: the small mark that identifies a browser tab

A site icon helps visitors recognize your page when many browser tabs are open.

Start with a simple square image that remains recognizable at a small size.

A detailed logo or tiny lettering usually becomes unclear in a browser tab.

In WordPress, open the Site Icon setting under Appearance or the Site Editor; its exact location depends on the theme.

Choose the image and keep the main symbol centered if a crop tool appears.

Save the change and open the public site in a new tab.

If the previous icon remains, refresh the page and remember that browser caching may be involved.

Place the tab beside several other sites and check whether your mark is easy to identify.

Also inspect it on a phone because browsers and devices may present it differently.

For a stronger result, use a clean high-contrast mark and keep the original image.
