# Message bar
## Display for affiliate traffic
For the customers, buying through an affiliate link is sometimes confusing, they might browse your site while having no idea whom they are actually referred. In that case, you should add a message to let your visitors know from whose link they are accessing your store.
The message bar will appear on top of your store, on every page (except the checkout page). You can customize the message to any text you want, as well as edit the font size, text color, or the bar background color.
Simply go to **Displays** > **Message Bar** > Edit the **Message** settings > **Save**. You can see the preview right below the settings:
When adding the message, you can also add a tag of **{affiliate\_name}** or **{company}** to clarify who the customer is buying from. The UpPromote system will replace the tag(s) corresponding affiliate's name and company.
In order to edit the design, please click on the **Customize** button:
