Every zubbit call-to-action link you create contains a message and a call to action button but also a photo and a name. Which photo and name a zubbit link shows depends on the brand that is was created with. A brand contains a number of settings: a photo, a name, and a home URL.
If you are promoting yourself, you would enter your full name and upload a photo of yourself as the Brand. If you are promoting a company, you would enter your company name and upload a logo of your business and likewise you could also use brands for particular products or services you sell or promote.
Remember, Call-to-actions are not the only clickable elements on a zubbit link. Visitors can also click on your brand photo or name, and where that links to is determined by the home URL you set.
