In your browser you have tabs for each website you are viewing. In each of these tabs is the name of the site page and a little icon called "favicon".
Now you can change that to one that is specific to your site.

good to know:

1. an icon file named favicon.ico uploaded to the web builder site will be used as a favicon for the site.

2. as an icon editor we recommend which is free and very quick to use

3. when you replace your favicon.ico, the new version might not be displayed for a while due to browser caching mechanisms.

Feel free to address your Implementation Manager if you have questions.
