You might wonder why there is no setting in the theme settings to create a link for the banner on the homepage and the banner in the sidebar. This is because our theme must be compatible for multiple countries around the world. As theme designers, we can include translatable text fields in the settings but not country applied URL's. For example, if your shop is active in French Canada and English Canada, you can insert a line of text in the banner and translate it through custom translations in the Lightspeed backend. But you can't unfortunately translate a URL. Therefor a link from the banner will either redirect to a French page, or an English page.
If your shop is only active in one country and really want to link your banner to a certain page, we can make a modification through the theme editor and create a setting for your shop only.
